The use of roller crusher should pay attention to what

The normal operation of the roller crusher, in many ways, depends on the degree of wear of the roll. Only when the roll is in good condition, in order to obtain a higher production capacity and discharge qualified product size. Therefore, we should understand the impact of roller wear and the use of the operation should pay attention to the problem; regularly check the roller wear and tear, timely repair and replacement.

When the ore is broken, the roll of the roller crusher is gradually worn. The main factors affecting the wear of the roll are: the hardness of the ore to be treated, the strength of the roll material, the surface shape and size of the roll, and the operating conditions, the way of feeding and the particle size. The period of use of the roll and the process index of the roller work depends on the uniformity of the distribution of the ore (material) along the length of the roll. If the material distribution is not uniform, the roll will not only wear quickly, but also the surface of the roll will appear annular groove, which broken product size is not uniform. Therefore, the roller crusher is basically equipped with a feeder, the length of the feeder should be equal to the length of the roller to ensure that the length along the roller and even to the mine. At the same time, in order to continuously into the ore, the feeder speed of rotation should be faster than the roller, about 1-3 times faster. In the operation of the roller crusher, but also pay attention to the size of the ore block, to the ore block too large, will have a severe impact, roller wear serious, especially when crushed.

In order to eliminate the uneven wear of the roller crusher, when the crusher is running, it should always pay attention to the size of the broken product, and should be in a certain period of time to move one of the rollers in the axial direction, the distance is about 1/3 of the particle size. When you need to change the crushing ratio and move the rollers, the rollers must be moved in

parallel to prevent the rollers from skewing. Otherwise, the roll will be quickly and unevenly worn, and will cause accidents.

Roller crusher work when the dust is large, must be installed closed safety cover. There should be a hole (check hole) on the cover to check the wear of the machine roll. In the operation of the roller crusher, you should strictly abide by the safe operating procedures, to prevent the hands involved in the roll caused by personal accident.
