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 .

Development of griddle should take the road of independent innovation

When a customer griddle pleading quality and performance increasing , while the current griddle existing technologies have not meet the needs of customers . From time to time so just griddle innovation , competence in the Chinese market stand foot footing . Also a large griddle industry is currently the only one way out !
According to statistical data coal vibrating screen analysis of the current large griddle consumer and small business have more than a thousand . When the griddle market once again usher in a new period of expansion after midnight, our griddle consumer 's way where is it ?
Although our griddle consumer business a lot, but less common are some of the range of small businesses. These technology companies are bringing technology from abroad , but these technologies in foreign countries who are some of the techniques to Mining vibrating screen be eliminated , assuming that these are the use of obsolete technology in China

That does not have the competitive edge.
Large griddle industry expanded in the coming years a trend has been reported in the major news online too . Therefore, screening equipment, mining expansion in the coming years is indisputable , the state and a lot of businesses are optimistic about the market . Although griddle had read in our country has experienced decades of

Expand the current range is huge. Once griddle has faced the frozen period, and as usual, real estate and infrastructure in recent years to establish a prosperous once again visibly large griddle industry , ushered in a new development period .
In addition , the current large griddle again commenced on behalf of the technically will have a higher level of increase, assuming still stay in place , not innovation , it can be said that the road ahead will be a dead end .

Crusher steel body and welded body distinction

Crusher same product the same model, the quality is not the same. Crusher into the body and welded steel body, cast steel body is called coal crushing plant entire body is one, steel

castings directly out of the body are one because it is such a device therefore quite durable,

A very long life. The welded steel body is composed by the multi-block, and then manually welded together, so that a much shorter service life of equipment. Welded steel body

and the body in the price gap is large, cast steel body price is relatively high, but the price is much lower welding body. A

Share price of a stock, here to remind you not to be stone feeding machine fooled by the manufacturer's offer, although some manufacturers give you the quoted prices are low, but the quality is

certainly not. In fact, distinguish the difference is very simple, you more consultation several manufacturers, and then listen to their offer, the regular manufacturers offer

Relatively high, while those small plants at much lower prices, the price is too low, or advise you not to buy. Here for everyone to look at the body and welded steel body

Roll crusher Basics Introduction

Double roll crusher is crushing machine, sand making series one. There crusher jaw crusher, hammer crusher, impact crushing equipment, compound crusher, etc.; there is a third-generation

Sand Sand, impact crusher, rod mill Sand and so on. Today we look at two-roll break

Crushers in the course of the first places to pay attention. Double roll crusher maintenance is a very important regular work, it should be extremely closely with operations and

maintenance, etc., should be full-time personnel on duty checks.


A, bearing: crusher manufacturer bearing shoulder the entire load of the machine, so good lubrication for the bearing life of a great relationship, it directly affects the life of the

machine and the operation rate, which requires injection of lubricating oil must be clean, seal must well, at the machine's main oiling

1 Turn the bearing (2) roller bearing 3 All gear 4. Activities bearing, sliding plane.

B, newly installed tires prone to loosening must always be checked.

C, Note the various parts of the machine is working properly.

D, pay attention to check the wear parts wear, and pay attention to replacement of worn parts.

E, put the base of the plane active device should be out dust and other materials in order to avoid the machine encounters can not be broken material activities bearings can not

move on the bottom shelf, resulting in a serious accident.

F, bearing temperature rise, the reasons should be eliminated immediately stopped and checked.
  
G, rotary gear when in operation should be immediately stopped if the impact of the sound check and eliminate.
The roll crusher working principle and structure
 
1, the series on the roll crusher is mainly composed by the roller, the roller support bearings, clamping and adjusting devices and drive components.

    2, the particle size of the adjustment: between two rollers or pads with wedge adjustment device, wedge device with the top adjustment bolt, when adjustment bolt will pull

up when the wedge, wedge away from the top of the active roller fixed wheel, two roller gap becomes larger, the particle size becomes larger, when the wedge

Down, the activity roller compression spring under the action of two gap becomes smaller, the particle size becomes smaller. Spacer device is a quantity or thickness of shims to

adjust the size of the particle size, while increasing gasket two roller gap becomes larger, while reducing gasket two roller gap becomes smaller, the

Smaller particle size.

    3, the drive mechanism is composed of two electric motors, by belt drive to the sheave drag roller, relative to the direction of movement in accordance with rotation. In the

broken material, the material from the inlet through the rollers, rolled and broken, crushed beneath the finished product is discharged from the chassis.

    4, for safety, transmission parts should be installed according to the actual situation of their own safety cover.

    Double roll crusher for mineral processing, chemical, cement, refractories, abrasives, building materials and other industrial sectors crushing all kinds of high, medium

hardness ores and rocks purposes, especially in the building industry in the production melon meter stone and green bean products, better than the average crusher

Different effects.

Roll crusher working to pay special attention to the following:

    1) To strengthen the work to iron ore. Non-broken (top brazing material) fall on the rollers will damage the crusher, resulting in parking accidents. So the crusher should

be installed before removing iron devices.

    2) crushing space viscous materials prone to clogging, clogging failure in handling should stop treatment, can not be stabbed mine in operation.

    3) When dealing with bulk materials containing large, easy to pay attention to chunks of ore from the crushing space squeezed out, to prevent injury or damage to equipment.

    4) roll crusher run a long time, due to the roll surface wear larger size too small will cause the product, then pay attention to adjust the port of discharge or overhaul of

equipment.

    5) to strengthen the inspection of the equipment, the equipment lubrication oil on time, keep the equipment well lubricated condition.
