1000 hydraulic roller machine, which is suitable for fine crushing operations with a feed particle size of less than 80mm and a finished product particle size of 50μm-20mm, can crush materials with a strength of ≤ 160MPa. In the coal industry, the roller is often used to crush the raw coal, as long as the raw coal is removed by iron, impurities, and gangue, it can be directly crushed, and the crushed material has uniform particle size and low crushing rate, thus simplifying the coal preparation process and reducing the investment and production costs.1. Appearance shape
The roller crusher is mainly composed of rollers, roller support devices, pressing and adjusting devices, plus driving devices, and the hydraulic roller crusher has an additional hydraulic system (protection device). The following is the roller crusher produced by Shangshanyou Heavy Industry Factory:2. Working principle
The working principle of roller crushing is relatively simple, and the whole crushing process is simply expressed as follows:
(1) The two motors drive the two rollers to rotate in opposite directions;
(2) When the crushed material falls between the two rollers, it will be crushed and crushed;
(3) Because the roller of the roller crusher is smooth, it not only has the function of crushing, but also has the function of grinding;
(4) The crushed small particles are thrown down along the tangent line of the rotation of the roller, through the gap between the two roller shafts;
It is worth mentioning that:
When encountering non-crushable materials (such as iron blocks), the hydraulic system in the hydraulic roller crushing will automatically retreat, so that the roller gap will increase, and the uncrushable materials will be spit out (discharged), so as to protect the machine from damage;
Adjusting the gap between the two rollers can control the maximum discharge particle size of the product (the size of the finished material);
