( 3 ) When the fine Netease damaged, fine mesh should be replaced to avoid affecting the quality of screening objects .


( 4 ) When the stainless steel frame export split, should be replaced.

 

Misunderstanding on the air screen

      Since most people do not understand the flow sieve expertise , there is often misunderstanding understanding of airflow sieve , which is the user's choice will cause great

interference.

Misunderstanding
    Tend to believe that the crushing and screening plant function of the air screen with its grinding mill as . Airflow sifter is a kind of mesh screening and grading equipment, mainly used in all kinds of

difficult fine sieve fine powder within the range of 50-500 mesh can be a good screening . Such as light calcium powder, active calcium , phosphor, wood flour

, Flour , manganese dioxide , sulfur powder , alumina powder. Crushing function which is only on the Feeding machine powder feeder blocks smashed into a group of favor over the net , no

grinding function.

Myth
    May consider massive and granular materials suitable for grading airflow sieve . But the flow is characterized by fine sieve sieve sieve coarse not so massive and granular

materials suitable for classification shaker, this point in the selection and screening fineness should pay special attention .

Compared with ordinary swing swing sieve sieve unique advantages

Swing screen is a fake artificial rock bass vibration sieve, which has large capacity, fine sieving characteristics meet all fine and ultrafine range of powder and particulate

material , particularly suitable coal crushing plant material is difficult to handle. YBS series swing sieve and some other big advantage is its unique clear network devices

.

    Traditional vibration screening device is not clear network devices , due to a variety of materials itself has a strong adsorption, easy to hold together , high static, high

precision, high density , coal production line light weight and other features, easy to plug holes in the mesh screening process, thus reduce the life of the screen , which greatly affect the work

Efficiency and screening effects.

    Swing sieve screen cleaning system means using different materials required to make the life of the screen is greatly improved, while improving work efficiency. Achieve the

following effects :
1 , accurate to six separate screening efficiency up to 90 %.
2 , acceleration 4.5 times lower than the shaker , screening component life and reduced maintenance to improve .

Mill and crusher marriage a big success

In the field of grinding mill has been in the position can not be replaced , there is little other processing equipment can like it on the ground so fine material processing in

order to achieve the desired breakdown finished mine . However, the problem has cropped up . That is, in many cases , mobile screening plant a ball mill grinding of

Is ignored , and the excessive use by the user in the field of broken material . If this process of changing its long years without paying attention to the environment , will

bring very serious consequences.

Visited the mill production plant people know that in the course of processing mill in the cylinder wall ,crusher plant manufacturer  not curled manually , but the use of compression molding equipment for

rolling . The technical requirements of this rolled steel plate thickness can not be too thick , so the device is in the works after forming

After calculating the results of the strict division ideal thickness of the state. If you do not follow instructions for the production of the product , it will be on the inner

wall of irreparable harm , leading to the cylinder wall or grate plate hole fracture effectiveness , requiring a lot of money to repair or buy new

Equipment .

Things always has two sides . Due to lack of funds budget , some manufacturers prefer to not follow the product description specification parameters for production , and the

option of using the experience of manual workers milling grinding operation . This is extremely dangerous thing. In order to make this part of the market

The user can use a reasonable standard equipment , Xinhai Machinery highlight of this improved mill production line.

This production line by a simple means for the crusher crushing operations necessary to reduce the burden of the ball mill . Through its work with the same motor to work on the

line when the differential . For conveying the track ball and fix the speed ratio according to the adjustment of the crusher discharge port

Ore mill speed parameters .

Tests proved that this mill crusher , and the marriage of the simple means of a ball mill can effectively reduce the wear and improve the grinding efficiency of the mill .

Because in the absence of the use of this device is similar to filter crusher collaboration, if for some natural yield

High ore grinding while reducing costs , the mill has a 20% -30% of the performance will be spent on the broken condition . Such step specialized production line design can

greatly reduce production failures and finished production cycle.

This technology is the Xinhai machinery processing equipment department in comprehensive comparison of various programs to improve the grinding efficiency and ultimately choose

to put into production scenario . This scheme can effectively reduce each election crusher plant in terms of investment as well as in the maintenance and updating of mill

equipment brought

Operating costs.

Selection and use of the crusher crushing Introduction

Beneficiation process in general , as a member of the crusher mineral processing equipment , mainly for handling the initial processing of the ore , the ore crushing engineering

. So, how to effectively select Linear vibrating screen the appropriate equipment to carry out supporting the production and processing of it? For this reason, Xinhai machinery to provide you with the

following solution

Case , and I hope for your production activities play some help.

First, we must be clear Mobile crushing plant that the scope and included in the models , fine crusher . Simply put , crushing hard and medium hard ore in the ore , crushing equipment , generally

used cone crushers ( including single-cylinder hydraulic cone crusher ) . Broken equipment generally used in standard

Cone Crusher ; crushing equipment selection of the short head type cone crusher ; handle special hard ore , can be super-heavy cone crusher , small two-stage crushing plant ,

the second choice of medium cone crusher ; broken frangible sexual material , can be used for roll crusher , impact or hammer

Crusher.

Secondly, we crushers for different application platforms and environments , to a reasonable choice of equipment into production. For example , cone crusher, hydraulic cone

crusher especially crushing force, light weight, small dimensions, low price, large production and processing , large crushing ratio , easy

Realized iron ore port protective case automatically adjust row . But should pay attention to the hydraulic system and the dynamic cone manufacturing support structure is more

complex and difficult to maintain factors.

Again, the roll crusher for crushing brittle materials or avoid excessive pulverized material . The advantage is a simple structure , easy to manufacture . However, since the

rollers should see and easy to wear low capacity shortcomings .

Again, the more popular crusher or hammer crusher is suitable for crushing hard though ores, particularly the fragility of the material . But the disadvantage is very obvious,

such as hammer and back plate is easy to wear and require frequent replacement ; big noise. Crusher broken over the hammer

Crusher location, has been widely used in the coal and non-metallic mining crushing operations, less metal mine concentrator applications. So, consider the user selects Xinhai

machinery crusher or hammer crusher crushing fines should be selected according to grade .

So how to choose the appropriate level in accordance with crushing fine products? Accordingly , Xinhai Machinery reminder, if specially produced 10-0mm fine grade products, you

can choose to BS-UF ultra- fine crushing cone crusher, the processing capacity of 50T / H, 3.35-0mm crushed product size fraction content of 45 %, while

6.3-0 grain grade levels as high as 80%.



If the product is less than 7mm size requirements account for more than 80% , you can choose super-heavy SXHD cone crusher , this model is a spring cone crusher categories , in

addition , GP disc crushing machine is a good choice. It is an improved type of crushing chamber cone crusher, which

Product features are fine and uniform .

If the face is hard to wear ore , you can try specifically for this type of ore KHA inertia cone crusher can reach the crushing ratio 15-20 , open conditions, broken particle

size of less than 10mm.

Talk about the basics of cleaning sieve

  Particularity of grain production , in order to achieve satisfactory cleaning effect , the equipment selection and use to do the following: ① granary is now equipped with complete sets Vibrating feeder of equipment production operations are 50t / h, yield than rice, flour plant is much larger , and the larger impurity grain on the market , the choice of such a sieve type, note that the best choice sieve sieve surface width 1.8m , 1.8m width as the screen type is a double feed, can be adequately using the effective width of the screen surface for sifting , screen machinery and 1.5m in width of the screen surface is a single screen -type material inlet , the material layer is concentrated in the middle of the screen surface , the screen surface itself is narrow , plus the problem, the flow can not meet the 50t / h production requirements. ② The sieve -type light impurities removal efficiency is higher, can better meet the production requirements , but be careful collection hopper to promptly clean up , it is worth noting that boot with particular attention to light impurities auger rotates in correct direction , otherwise once the operation reverse , it will cause clogging . 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, and other fibrous valley shall be very sensitive to impurities . 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 .

Basic knowledge of cleaning sieve

    Cleaning sieve with advanced level of impurity cleaning equipment . Its simple structure , small size , large output , wide application , good sealing performance . Helix angle with crusher manufacturer adjustable playing board and cleaning brush , can be suitable for different impurity content of materials cleanup. Sliced ??big screen cylinder and double door structure , operation and maintenance simple and quick to make .
How it works: The machine 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 plate feeder agglomerated material is broken up, along with a plate in circular motion around the cylinder surface , under the effect of centrifugal force , less rapid screening sieve material from the lower part of the body from the plane, close to 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.
