Screening machine type

Coal-fired power plant boilers burning coal gangue certain percentage of granularity in the coal mines to its uneven particle size, particle size of coal there are qualified majority of particle size, need not be repeated broken. This part of the material generally comprises from about 35 to 75% of the material. Now many domestic Linear vibrating screen equipment. Commonly used screening equipment can be divided into two categories, one is vibrating conveyor type, one is forced to transport type, advantages and disadvantages between the two. The best situationto be root to the parameters noted in the selection of materials.
Sand vibrating screen machine of fixed sieve sieve categories and events, activities, sieves and sieve is divided rotating shaker. They use a fixed sieve grate mounted on top of the import crusher to prevent materials falling into the super-size. Most of the panels folded rotating sieve sieve polygonal or circular cylinder madeof simple structure, long life, but productivity is low, the body heavy, huge, but rarely used.

What often encountered failure swing sieve

Swing sieve is an anti- artificial low frequency vibration sieve shaking , when in use often encounter a variety of failures, affecting swing sieve efficiency, the following

Xiaobian to introduce Dry vibrating screen swing sieve which often encounter failures.
When using swing sieve , be sure to do regular inspection, review the problems identified , swing sieve should be repaired . Screen frame side plates and beams should avoid

stress concentration , coal mining machine swing sieve is not allowed on these components soldered . INSPECTION AFTER REMOVAL sieve swing bearing wear, check the gear tooth surface , check the

condition of each component coupling , swing sieve cleaning the lubrication circuit box to make it clear, cleared the combined surface attachment , shaker replace all seals and

other damaged parts.

What is it in the end shaker

     Do not understand a lot of people do not understand what the machine is vibrating screen, vibrating screen in the end what is it ?

     Vibrating screens are from the hopper , vibration chamber , coupling and motor. Indoor oscillation by sand vibrating screen the eccentric wheel, rubber software , main shaft, bearings and other

components. Adjustable vibrating sieve eccentric weight communicated by the motor drive to the spindle centerline , in an unbalanced state of the centrifugal force , so that the material

strength is varied form vortex in the sieve . Adjusting the amplitude of the hammer according to different materials and screen adjustment.

Sieve shaker causes breakage

Vibrating screen mesh showing linear fracture , generally due to tension ( not tight or pulled ) States crusher plant should support twice on the screen between the formation and shaker boxes

on the screen , and the other straight net impact has been breaking the rules , resulting in some of this damage may be:
    1 , the screen size is too long , causing tension screw loose sheet ;

Overview of the use of cleaning sieve

Wuhan, central grain depot using shaker model TQLZal80 × 200, this sieve type original common rice, noodle factory in liquidation phase after the procedure . As the

particularity of grain production , vibrating screen supplier in order to achieve satisfactory cleaning effect , in the selection and use of equipment to do the following:
Granary is now equipped with complete sets of equipment production operations are 50t / h, yield than rice, flour mill is much larger , and the larger impurity grain on the

market , the choice of such a sieve type, note that the best choice for screen surface width 1.8m sieve , sieve -type because the width of 1.8m is a dual inlet , to take full

advantage of oscillating screen screening

The effective width of the sieve surface processing , and 1.5m in width of the screen surface of screen type is a single inlet , the material layer is concentrated in the middle

of the screen surface , the screen surface itself is narrow , plus the problems, the flow can not meet 50t / h production requirements. The sieve -type light impurities

removal efficiency is higher, can better meet the production requirements ,

But pay attention to timely collection hopper cleaned , it is worth noting that boot with particular attention to light impurities auger rotates in correct direction ,

otherwise, once running reverse , causing blockage. ③ The sieve -type small miscellaneous cleaning effect is better, because the screen surface with a self-cleaning ball ,

clogging . However, the screen on the ropes,

Valley of other fibrous impurities to be very sensitive . If too many of these impurities , cleaning is not timely , it will live in a big mixed paste the screen surface , so

that the effective screen management area is reduced , causing some food grain exports flow to large complex , affecting equipment production and cleaning effect . Wuhan,

central grain depot in general use, a vehicle cargo

Shut down after it cleaned once , a long time such impurities , 20min non-stop on the machine easy clean up once .

First, the application areas:
 Cleaning sieve is mainly applied to grain feed processing, cleaning accessories cleaning, lumpy material dispersed, especially for use after the mixer as an insurance sieve .

 Second, an overview :
 Advanced level of impurity cleaning equipment . Its simple structure , small size , large output , wide application , good sealing performance . Helix angle with adjustable

playing board and cleaning brush , can be suitable for different impurity content of materials cleanup. Sliced ​​big screen cylinder and double door structure , so that operation

and maintenance

Quick and easy.
Third, it works :
 The aircraft in the material fed from the feed inlet screen cylinder , the playing board by rotating the impact and delivery role, so that the material in the agglomerate

material is broken up, and with the surface of a plate with a circular motion around the cylinder , the centrifugal force under the influence of the material is less than the

sieve sift quickly from the body lower discharge

Out of the machine, close the screen cylinder cleaning brush ready to hang on the sieve to remove material on the tube . Greater than sieve large miscellaneous transportation in

playing the role of the board under the direction of exports to the passage of large miscellaneous discharge.

Reduce vibration motor heat

General Motors by fans to heat, and vibration motor but often require manual maintenance cooling . Ordinary fan motor work along the casing above the wind kept hair heatsink ,

cooling rapidly while paying off the dust in China Vibrating Screen addition to the above , so that ordinary motor temperature generated by the work

Ensure normal .
Vibration motor without fan unit is on its own heat . However, the working environment of dust vibration motor is relatively large , long-term and more likely to accumulate in

the surface of the motor will affect the sand vibrating screen cooling effect , can cause overheating , burn out the motor .
Preventive measures:
1 periodically clear the motor surface dust, the vibration motor has a good working environment .
2 vibration motors preferably with good ventilation when using generally not a problem in the winter , in the summer you can use fan cooling.
These two points will help customers maintain a vibration motor vibration motor, vibration motor life expectancy.

Vibration sieve what trajectory

   Also known as three-dimensional rotary vibration Vibration: The vibration of the vibrating body the projection on the horizontal plane trajectory is a circle or an ellipse , in the form of vibration is called spin vibrations. Such shaker to be known vibration sieve . Rotary vibration can be divided into flat spin type vibration , vortex -type rotary type vibration vibration and complex three forms . When the

Vibration of the vibrating body in the mobile crushers for sale vertical plane of projection trajectory is a horizontal line , their vibrations called a swing -type vibration ; when the vibration in the vertical plane that the trajectory is an oblique projection of a straight line , its vibrations called vortex rotary type vibration ; when the vibration body vibration in the vertical plane of the cast locus

Shadow of a circle or ellipse , its Semi-mobile crushing plant called complex spin type vibration . Usually consists of vertical vibration motor vibration equipment generates spin excitation vibration , the vibration form then look at both ends of vertical vibration motor excitation depending on the angle block . Also be two foot mounting type vibration motor vibration design aliquots

Preparation sides , it was for a set point of the shaft , the vibration of the vibration device will also produce rotation

Analytic disc feeder and feeder works

Disc feeder from the plate feeder body , drives, metering belt conveyor and metering devices , is suitable for the following fines 20mm feed . Disc feeder and conveyor drive means by

a set of the electromagnetic clutch drive device can be realized feeder opening stop ,

And both functional conversion effect.
Feeder in the production process , can the massive, granular materials from silos timed , evenly and continuously into the affected device to go in the gravel production line

crushing machinery for continuous uniform feeding , and coarse screening material , widely used in mineral processing , metallurgy, chemical

, Coal , building materials, abrasive and other industries crushing and screening equipment . Belt feeder according to equipment performance requirements , configuration, materials

should be designed to minimize the pressure on the tank , Bunker discharge port shall not be greater than the effective width of a quarter , the material flow speed control 6 -

18m/min. Right to a larger quantity of materials , in order to not affect the performance of the feeder , stopped mining board shall fix the tank body ; hopper bottom discharge

should be set high enough to block mine boards.

The use of more than one job at the same time sand shaker

The use of multiple sand vibrating screen simultaneously, the waste can be re- oscillating screen , improve utilization of sand can be sieved material directly into a similar

specification and qualified material becomes waste into treasure. Reduce the amount of sand lost shaker of more than 50% . Also in the use of sand vibrating sieve machine

When the water-wash system can be added , and through the circulation to solve the problem of waste water . Rinse sand, gravel , clay content to reduce excessive phenomenon .

But also through the water cycle, can work day and night , do not worry about water decreased. However, in the purchase of equipment , when sand shaker ,

To do civil foundation work hardening production site in advance to avoid poor planning resulting slowdown rework phenomenon.
Fertilizer shaker with low energy consumption , high output , simple structure, easy maintenance, fully enclosed structure , etc. . No dust shaker fertilizer , automatic nesting

, more suitable for pipeline operations. Fertilizer vibration sieving machine of single and multi-layer, suitable for different customer needs, but also for customers

Individually customized.
Large angle direction of vibration shaker design angle 45 °, horizontal effect is able to make large angle vibrating sieve machine performance parameters are reasonable

configuration , to get good speed and handling of materials and high volume screening efficiency. But according to individual process requirements and certain special

Special needs vibrating screen can be placed at an angle , generally 5 ° or 10 °. Inclined vibrating screen is mainly used for fine grading and dehydrating materials off the

mud , etc., so if the angle is too large , it may lead to poor screening efficiency .

Vibration motor development prospects in the industry

Vibration motor industry in the future , micro vibration motor with high performance and with precision motor control systems will play a leading role in the appearance of

ordinary generic heavy Mobile crushing plant motor , the vibration of its own devastating more serious , direct impact on their life and performance play . Special

Do not be in a mine field of application , maintenance and repair are far below standard, especially with the continuous use of dust pollution , bushings and lubricants is not

timely cleaning of non-compliance . Reform of new mobile screening plant products, take the high road , the development of precision and small vibration motor vibration motor development, especially

Mine explosion-proof vibration motor development . The introduction of foreign vibration motor technology , the development of self- economy is a major factor in the development

of enterprises and competition embodies the essence .
Lack of sharing of domestic vibration technology industry , the slow development of its technology , the phenomenon showed a significant difference between the two , micro

vibration motor vibration motor and general principles on the technical and less communication , the lack of cooperation between enterprises , the profits of ordinary vibration

motor gradually reduced, the new motor

Combined with the development of the electronics industry technology, research and development on the original multi-purpose product technical issues , such as mobile phone

vibration motor vibration motor used in flat , medical and health supplies that are used in vibration massage motors. Will be the future of high-margin products.
Many manufacturers are now shouting industry profits fell to a low vibration , vibration motor prices have fallen to historic lows , the quality can be guaranteed , regional

brand can be protected and development of all enterprises are worried about the two years of raw materials continue to rise, indeed

Affect the vibration industry, but certainly not the main reason for development of enterprises encounter difficulties .
Imports in the domestic application of the vibration motor limitations and more problems , first of all maintenance and repair problems in the country is difficult to solve ,

mounting dimensions are different, resulting in domestic motor can not replace each other, the differences Furthermore technology and performance differences. We can see that

the development of the domestic industry, the vibration

With foreign countries there are still a considerable gap . Absorb foreign technology into I , the formation of research teams , research and development of their products , is

an important issue for future development .

Screening machine installation place should be spacious and airy

         Repair screening machine, regardless of the use of the site, or in the assembly plant, screening machine runs in, use a rope around the screening machine 500mm distance

across the region, the general staff not to enter the area. Clean vibrating screen supplier, only in the screening machine is completely stopped state for

. This double roll crusher and different opportunities for cleaning clogged sieve, sieve can tap wooden hammer, so that the material blocking the hole prolapse.
   
        Screening machine installation place, sand washing machine should have the necessary ventilation and dust removal equipment, so that the necessary screening machine

around sanitation. Easy to produce dust for screening materials, screening machine deal will be closed, and dust removal system connections. High-speed rotation of the flywheel

counterweight

, With weights on the pulley firmly fixed to prevent screening machine is running, flying out with weights. In the screening machine running empty, the non-repair personnel

remain in the vibrating sieve surface. Operation and maintenance personnel screening machines, screening machines must learn the technical knowledge, and general mechanical

power

Gas safety technical knowledge.

        Screening machinery parameters and performance testing, usually in the screening machine crushing machine manufacturing is complete, the manufacturing facility to

validate the manufacturing vibration screen parameters and performance to meet the design requirements. Such trials generally known as factory tests. In the use of on-site

screening machine

, The machine is installed, the installation of screening machine for testing the quality of engineering and inspection work of the screening machine performance, but also need

to be tested and performance parameters in order to determine the screening machine kinematics and dynamics parameters and performance, acting on the basis of identified dynamic

What are the advantages vertical crusher

Vertical Crusher mainly vertical impact crusher and vertical compound crusher. Vertical Crusher advantages: simple structure, easy operation, energy saving, grading crusher,

dust is small, good wear resistance, long life, and uniform distribution of materials. In addition, vertical crusher

No sieve, thereby overcoming the crusher often high frequency screen clogged. Vertical crusher hammer link uses hinged structure, easy to replace. Vertical crusher surface mounted guard serrated

liner, thus improving the degree of breakage of the material, reduces the noise, increasing

Added wear resistance. Vertical crusher is also an important feature that can be added in front of the traditional ball mill. Preceded by a vertical mill crusher is mainly to

reduce the particle size of the material so that it can play a role in energy conservation. Energy conservation is not only the survival of enterprises

Conditions, but also enhance competitiveness and develop strength needs.

Cake timber body hammer crusher innovations in devices than the car

One, cake hammer mill sieve corners improvements

General cake hammer mill sieve wrap angle of 180, ie entire cake entry through the feed into the crushing chamber after repeated hammer blow, collision, friction to become

powdery material, and the centrifugal force and radial airflow under the effect of flow through the sieve into the secondary crushing process exhausted to the outside.

Because cake hammer mill sieve real effective wrap angle less than 180 in the operator pusher momentum caused when too much lower spindle speed, the centrifugal force and radial

flow decreases. This will affect the flow of mobile crushers for sale, so that part of the material required to achieve granularity stranded in the grinding chamber.

Therefore sieve wrap angle increases to 270, changing the mill working conditions, so that mill production efficiency.

Two, two fixed hammer mill cake cutter design

9FB-2 type, 9FB-45A type, etc. cake hammer hammer mill can be transferred activities mostly hammer, usually 32, divided into four groups staggered. Hammer sieve clearance 12mm,

maximum working spindle diameter 500mm, coal crushing plant chamber width 600mm. Installation activities hammer hardness than the advantage is that when

Big cake material feeding, the cushion. Piece of cake as shown in the partial 80 angle tangential direction feed mill. If the operator pushing the momentum is too large, the

spindle speed will drop the hammer sieve gap increases, activity materials hammer crushing capacity decreases, the activity hammer

Under the crushing blow particles increases, so that the material remain in the crushing chamber, resulting in a further decline spindle speed, appear spacious car.

According cake hammer mill this spacious car problem, designed to increase the two fixed cutter. When the operator pushing momentum is too large, each of the two fixed blade

cutter located between two active hammer, the hammer from its maximum working edge radius 10mm, pieces of broken material limits

Grain increases. Make up the momentum caused by human spindle speed spindle speed down a vicious cycle.

1, the cutter arrangement, such as installation and 2, the cutter pulverized material selection characteristics of the cake, its hardness little higher cutting speed, and the

secondary cutting, cutter cutter main consideration the choice of materials toughness and resistance to grindability.

A support plate 2 activity hammer hammer 3 4 knife fixed blade fixed shaft 5 hammer fixing shaft

A fixed cutter 2 Activity 3 hammer hammer cutter fixed shaft 4 fixed shaft

Third, improve the technical parameters before and after the cake grinder and Performance Analysis

Cake with 9FB-2 type hammer mill, for example, improved cake cutter hammer mill sieve wrap angle increased from 180 to 270, row material capacity increased by 40%. Designed and

installed two sets of fixed cutter (the cutting rake angle 30 number 36) 36 Cutter were installed in 18 hammer

Intermediate support plate is located between the two activities hammer. When the spindle speed is reduced, the cutter will limit excessive particulate material produced. Cake

smash in the unit production continuity, stability has been greatly improved, to avoid the occurrence of spacious car, significantly improve production efficiency and reduce

Energy consumption of about 25 - 40%.

How to prevent failure shaker

 
    As a non-standard equipment shaker vibration equipment for most users, the shaker may all devices in the user hardly a major equipment; however shaker failure frequency is

higher than the traditional power machinery products, because the vibration device itself is a kind of vibration destructive conduct scientific use of a product. Equipment for

conventional mechanical vibrations, it means that the occurrence of failure sign, and by vibrating the vibration device is precisely the work required to complete one purpose

and requirements of a product. Although the vibration industry are committed, anti-vibration device itself destructive optimized structure design and research, but still  Semi-mobile crushing plant

vibrating equipment failures occur frequently. And shaker is often arranged in the user's throat production process, once the shaker fails, it will cause the entire production

system linkage Parking, giving users a significant loss of production. On mining, coal, metallurgy enterprises, such as a sudden stop repair one day, then at least ten direct

production efficiency loss of tens of thousands, as many as hundreds of thousands or even millions of dollars. To avoid this phenomenon, the user only keep abreast shaker

operating conditions, to discover hidden maintenance arrangements well in advance.  crusher plant manufacturer
