The Features and Application of Rolling Crusher

Descripción

The roll crusher that we often use has the following advantages: simple structure, convenient maintenance and low manufacturing cost. However, this equipment has low production capacity and big size, for this reason, a large space and size will be needed when installing it.Ore-dressing equipments mainly include cement mill,ball mill,rotary dryer,flotation machine,etc. In addition, since the abrasion of the surface of the rolls is not even during its working process, frequent repair will be necessary.

This machine is a kind of crushing equipment which is commonly used in such industry as cement, chemical, ore dressing and coal processing and it mainly crushes rock and ore materials with medium hardness. Its working process is: The fixed part of roller and movable roller are driven by the motor via reducer and v-belt, the raw materials fall into the part between the two rollers from inlet of the machine. The two rollers rotate inward simultaneously. The materials are extruded, crushed and ground, and then the end products come out from the bottom of this crusher.

The roll crusher that has glossy rolls mainly crushes the materials by squeezing and grinding, for this reason, this equipment is mainly used for medium and fine crushing clay, coal, clinker and limestone. The roll crusher with two toothed rolls mainly crushes the materials by splitting and tearing, and this kind of equipment is mainly used for completing large size material crushing.

Through the analysis and calculation of the crushing force of the roller crusher, we can get the impact of the hardness of the materials, the change of the filling rate of the crushing cavity, the change of the discharging port and the change of the crushing cavity on the crushing force of the roller crusher.

We should study the relative kinematics of the working principles and the working mechanism of the roller crusher through the whole crushing process of the materials to establish the kinematics model of the roller crusher. The experts have analyzed the empty load and load situation of the roller crusher and we have known the angular velocity of the roller is determined by the center line of the crushing equipment. The distribution of the material layer in the crushing space has certain impact on the angular velocity. In addition, the relative motion of the roller has certain impact on the working performance of the crushing machine.
