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.
