LM Vertical Grinding Mill

Grinding Mill is a common industrial grinding equipment, can grinding particle size smaller materials into fine powder. Mill general cost is higher, in order to avoid the malfunction, the actual production to pay attention to the correct operation and use, need to abide by the three basic principles are as follows.

The operation of the grinding mill. Advanced machine intelligence, then, are still need to human, and principle of the operation of the mill is not completely automated, needs to be professional in the operation of the entire staff's control. In addition to the full in, the operator must master the accurate operation of the grinding mill technology, if only by a few days or is the so-called self-taught type personnel training can't let him alone, otherwise easy to cause accidents. Let not skilled personnel is one of the most obvious defects in the wastage of the machine is too large, they do not know how to operate to minimize loss. Before the operation must be professional training to operators, only in the thorough understanding of the working procedure, to make them independent operation.

Mill grinding material choice. Although mill can process a variety of different materials, but for some specific materials is absolutely can't carry on the processing, if not carefully put the material in easy to damage the machine. So the mill operator must be aware, it is forbidden to those material to enter. Such as some pieces of metal into, because the hardness of the metal is too large, the machine could not be broken, will damage to itself, so once discovered immediately stop, otherwise it will damage the roller. Control the moisture. Mill in use, it is necessary to strictly control the moisture content of materials. In other words, can't let contains a lot of moisture of material into the machine. Because the material moisture content is too large, the powder grinding machine qualitative very sticky, not only reach the effect of grinding mill will impact machine.

A grinding mill is not complete the task, is the need to consider various factors, depends on how much raw material, how much is the humidity, if too much raw material is needed to use the machining of crusher broken first. And if the humidity but also add the dryer.
