zhenyuan Belt feeder Moisture effect of coal sieving machine

External water feeding coal is the main factor affecting the screening, the general external water below 6%, zhenyuan crushing and screening plant can be very good for dry sieving; such as external water more than 6%, sieving difficult. Wet sieving flushing often achieve better screening efficiency. The general screening plant with dry screening, cleaning products can be used wet sieving. In the external moisture below 6%, the mesh using 13mm available general vibration sieve for dry screeningzhenyuan vibrating screen design has achieved goodeffect, such as the pore size of 6mm dry sieve, sieve is generally not good effect.

The surface of zhenyuan screen machinery width determines the processing ability of sieving machine

The surface of the screen width determines the processing ability of screen, if the screen wide material through capacity; sieve surface length determines the efficiency ofZhenyuan Mining vibrating screensurface extension, the longer the longer materials through Zhenyuan coal crushingplant, screening more thoroughly, however, long sieve to improve screening efficiency is not significant, but only the excess lengthened screen size.The current screen, the screen length, screen 3.5~4m coarse grained, screening 5.5~5.6m fine, dehydration, de mediated 6.5m.

Vibration sieve problems during use

Vibration sieve used in various industries, although the vibration sieve is already a very mature product, but there will be some difficult issues , such as : vibration sieve

during normal operation , due to all China Coal Ranbow Mortar Mixer Machine the characteristics of the material , will produce different shapes various forms of the sieve clogged. Block

The main reasons are the following :
1 , contains a large number of particles near the separation point ;
2 , materials with higher water content ;
3 , the spherical particles, or the mesh material having a plurality of contact points ;
4 , can be electrostatically ;
5, the material has a fibrous material ;
6 , the sheet more particles ;
7 , oscillating screen wire weaving through thick ;
8 , such as thick rubber mesh sieve , hole shape design is unreasonable, did not reach the small great , leaving the particles stuck. Because of the need screening material

particles are mostly irregular , so blocking reasons are varied .

Must understand the current situation of broken jaw

Jaw crusher , also known as broken jaw , or the tiger population , is widely used in mining, smelting, building material, highway , railway, water conservancy and chemical industry in various ores and medium-grained bulk materials broken . The maximum compressive strength of the material to be broken is 320Mpa.
 So double roller crusher life and work efficiency is directly linked with the cost of business , but now the domestic jaw crusher manufacturer's technical level is the disparity , the need to carefully consider the options .
Most manufacturers of products with the world advanced level far . Take the jaw crusher frame , the frame is divided into cast frame and welded frame, domestic jaw crusher rack is not crushing and screening plant reasonable to use , there is no force in accordance with the actual layout of the ribs, led to the domestic level and

The level of foreign gap.
Of two jaw crusher , jaw with static jaw , palate with just crocodile jaw. Jaw crusher in the design process, to consider is the best moving jaw movement characteristics while moving jaw jaw with the force of static arrangement of ribs, improve crusher performance. Another point is the country

Need to be addressed within the subject crusher , jaw crusher machine need to reduce weight .
Another jaw crusher also need to be improved in several aspects: low yield, large limestone crushing, power consumption , the liberation of labor intensity and the work environment .

Vibrating sieve iron accumulation how do online

CLAY vibration amplitude is too small, difficult conditions in the polymer drilling fluid stone screening machine, can not effectively overcome the drill cuttings (clay) of viscous forces,

resulting cuttings accumulation in the sieve shaker Circular vibrating screen and quickly damaged.

Solution: ① increased vibration amplitude; ② flush with spraying sieve shaker and cuttings, reducing the viscosity of the cuttings, but this method only allows the addition of

water suitable for the occasion; ③ Adjust the mouth end of the row of sand screen angle down conducive cuttings discharged by gravity, but it may cause

Running pulp; ④ replacement mesh sieve shaker single screen or adjust the flow of drilling fluid flow only point to ensure close mesh export, so that the cuttings in the

drilling fluid lubrication smoothly discharged.

Feeder series development of product diversification

Although the level of ordinary agricultural engineering machinery products is not high, but after several years of development, agricultural machinery is moving "from low to

high, from coarse to fine" and diversification, serialization direction, from the initial work only consider action, shoddy, which focus on the development of today

Performance and pay attention to appearance, product quality and manufacturing standards have markedly improved, increasing banana screen satisfaction. As the market continue to be

optimistic, production and sales will continue to increase, further expand the scope of use. Of course, there are a lot of manufacturers and products need to change

Forward and lift motor feeder high. Most agricultural machinery manufacturing enterprises feeder industry strength is weak, due to intense market competition, many companies at

low prices as a means to win the market, leading to lower corporate profits, poor efficiency, the production run is difficult, there are companies constantly stop and turn

Screening machine mining industry in recent years has become a star

        In the screening machine and feeder for use on rubber springs, often due to equipment vibration trajectory is a circle or a straight line, so the rubber springs

generally subject to two kinds of compression and shear deformation state. Rubber spring design is based on job requirements, need to identify various dimensions, calculate the

stiffness and strength check. So you can use gravel production line equipment from. The viscoelastic properties of the rubber, to absorb the vibration of the selected frequency

band, therefore, the spring is relatively small noise.
   
        When calculating the rubber spring stiffness, the first to determine the elastic modulus, calculated spring form factor, and then calculate the spring stiffness. When

the stone screening machine work, rubber spring work in dynamic compression deformation state, then said that the relationship between load and strain, called compression dynamic

stiffness. Rubber spring such as working at different temperature conditions, but also the rigidity value by the range of the temperature coefficient m7.
   
         Screening machine used in making rubber springs calculations, shaped to calculate the stiffness of the spring. To more accurately calculate the spring stiffness of the

vibration system, according to the vibration Circular vibrating screen direction angle to calculate the compressive deformation and shear deformation, and then calculate the

corresponding stiffness. The compressed combination of stiffness and shear stiffness vibration system to calculate the stiffness. Rubber springs still need to calculate the

compressive stress and shear stress, the compressive stress is less than the allowable stress of rubber, rubber shear stress is less than the allowable shear stress. The

composite spring is a metal coil springs and rubber spring combination, that is, the surface-treated metal coil spring outside, including a viscoelastic rubber, the composite

spring has a metal coil springs and rubber springs the advantages of both.

Screening machine capacity and efficiency of screening interdependence

        With the growth of sieving time, the screen surface less easily sieve particles; left most "difficult sieve particles," grain size of the material is close to a mesh

size of these particles. These hard particles through the sieve sieve, takes a long time, screening efficiency increases more slowly. Therefore, the length of the screen surface

only within a certain range, to improve screening efficiency work, can not be over-extended length of the screen surface, otherwise the Screen machine bulky structure,

achieving the desired effect.
   
        Screening machine processing capacity and screening efficiency are interdependent, to a reasonable selection. Thus, the width and length of the screen surface to combine

consideration in order to determine a reasonable proportion of the width and length parameters. In general, the length and width of the screen surface ratio of 2 to 3. For

coarse materials, screening, screen surface length is 3. 5 ~ 4m; For medium fine grade material screening, screen surface length of 5 ~ 6m; materials for dehydration and

sculping screening, sieve surface length of 6 ~ 7m; sand vibrating screen of the screen surface can be shorter, the final screening sieve surface should be longer.
   
        All kinds of screening machine width and length to form a series of screening machine type spectrum. Crusher manufacturers believe that screening should pay attention to

the correct choice is very important.

Pharmaceutical industry requirements for shaker

Pharmaceutical industry requirements for shaker

The pharmaceutical industry and the people closely related to the relationship with the body, so the state of the pharmaceutical industry's requirements are very strict, the   stone feeding machine

pharmaceutical industry for screening materials are very strict, the most basic is the pharmaceutical industry to use vibrating screening equipment must be stainless steel 304

or even 316, does not allow access to some materials magazines pollution, rubber parts, etc. must also meet food grade hygiene standards (silica gel), and hit the pharmaceutical

industry requires screening equipment must pass the GMP production standards. Shaker used in the pharmaceutical area, has very strict requirements, must meet the pharmaceutical

industry GMP production standards, this relationship with drugs called through the sieve will be contaminated. In fact, is not complicated as a screening machine, the so-called

GMP standard, in fact, in the material, which must be 304 stainless steel, the rubber of choice, be sure to select pharmaceutical grade, the device must use alcohol carefully   Feeding machine

before delivery cleaning times, inside the device must be taken, polishing required to be smooth, polished inside and outside the machine, no black spots, no glitches. Handled

by various pharmaceutical manufacturers because different materials, some of the workshop, strict management, some drugs are flammable, so the choice should pay attention to the

motor for different materials, equipment installation and ordinary vibration motor or explosion-proof motors.
