Roll Crusher

Description

Introduction

Roll crusher is suitable for the coarse and medium crushing of crisp bulk materials in cement, chemistry, power, mine, metallurgy, building material, refractory and coal mines. The feeding granularity of this machine is big and the discharging granularity is adjustable, and the compression strength of the materials to be crushed should be below **0 MPa. When using this machine to crush raw coal in coal industry, after deironing and edulcoration without gangue removing, the raw coal can be directly crushed, and the crushed materials have even granularity and low over crushing rate, thus simplifying the coal dressing process and reducing the investment and production cost. The most commonly used roll crusher are double roll crusher(double roller crusher) and toothed roll crusher.

 

Working Principle of Roll Crusher

 

The main structure of the wheel gearing is composed of fixed roll, movable roll, drive shaft, machine box, chassis, cover piece and long gear cover. The motive power of the machine comes from the V-belt pulley of the electromotor, and a pair of middle reduction gear will make the fixed roll rotate, and then a pair of long gear drive on the other side of the fixed roll will drive the movable roll, and the two rolls perform relative movement to squeeze the materials.

Operation Notes of Roll Crusher for Sale

(1) Strengthen the deironing work. The non-crushable materials falling into the space between the two rolls will damage the crusher, which will stop the machine, for this reason, it is necessary to install a deironing device in front of the crusher.

(2) Sticky materials can easily block the crushing space. When processing blockage fault, the machine should be stopped and never poke the ores in the running process.

(3) When there are large materials, pay attention that large ores may be easily squeezed out from the crushing chamber, they may hurt people or damage the equipment.

(4) After running for a long time, the abrasion of the roll surface will be serious, and then the product granularity will be fine, then pay attention to adjusting the discharging mouth or examine the equipment.

(5) Strengthen the examination of the roll crusher, timely lubrication the lubricating part and keep good lubrication state.
