The main structure

Double roll crusher is mainly composed of the roller, roller bearing, pressure, and adjusting device, rack and drive components. Two broken the roller by the different methods of operation were referred to as the active roller wheel and the driven roller wheel. With key fixed in two spindles. Two have a set of bearing support of a shaft, and installed on the chassis. Two broken the roller by the different methods of operation were referred to as the active roller wheel and the driven roller wheel. Bolted on the chassis, active roll wheel driven roller bearing wheel is equipped with safety spring and activities. Its role is to protect the machine parts, in regulating the roller spacing or when falling into a metal debris between the roller and the driven roller wheel can move laterally, without damage to the machine parts.

The working principle of

The use of two sets of produced by the rotation of the roller relative extrusion and shear grinding force to broken material. When material into the double roll crusher cavity, tooth force by the active roller, make the material is forced through between the two rollers, roller extrusion and shear grinding at the same time, the material has been preliminary broken, cracked after the small particles along the roller rotating tangent, through two roller clearance, from below the discharge machine, particles larger than clearance material continues to be broken into small particles to discharge.

Double roll crusher advantages double roll crusher maintenance matters needing attention

Machine reasonable usage can directly affect the lifespan of the machine, so you need to pay special attention to the following points:

Double roll crusher should be installed on the basis of cement or concrete, or installed on the floor of the building. Keep ventilation condition, to avoid moisture to prevent rust machine. Due to the machine at work by the force of uneven, need to put wood in under the chassis, make the whole machine and wood joint, wood root number and general section refer to layout of roll crusher, also can choose according to the specific conditions of installation. ?

Machine after started, only under the running condition at full speed, are allowed to feed. Material must be evenly into the machine, material distribution on the roller length or the size of the incoming block should be uniform, and join the materials should not exceed the prescribed size quickly, or you will make the roll wheel produces Nick, lead to the roller wear prematurely.

Stop the machine, the first stop the supply of materials, until there is no residual material in the feed hopper, to stop the machine running, one side at the beginning of the next work, started in the feed hopper with the rest of the material and cause overload and failure.

Compression spring, standing and important position in the whole process. It can support the sliding bearing, driven wheel constant pressure to crushing material, at the same time when there is a metal impurity content accidentally fell into the roller, the spring is compressed, the driven wheel lateral movement and get out of the way, can play a role of safety. If spring preloading is too small, make the roller between the lack of enough pressure, not only affect the yield and the discharging granularity, at the same time produce lubricating bearing and chassis caused by excessive relative sliding wear. To do this, you need preloading workers often pay attention to the spring. When the sliding spring, must immediately.

Protected drive colloid triangle, don't make the glue has damaged oil, when used to keep a certain tension of belt, may not be too loose, otherwise it will cause a skid belt heat and wear.

Machine, rigorous cleaning and add lubricant, lest produce life risk.
