Grinding mill is one of the equipment used in the powder industry for grinding and processing of non-metallic minerals must be able to quite a lot of equipment. Vertical mill with high efficiency, low power consumption, small footprint, small one-time investment, widely used in barite, calcite, potassium feldspar, talc, marble, limestone, dolomite, Ying Shi, lime, activated silica, activated carbon, bentonite, kaolin, cement, phosphorite, gypsum, glass, thermal insulation materials, etc., then what are the precautions in the operation of the vertical mill?
1, before starting the vertical mill, you should check whether there are iron and other debris in the machine, check whether the bolts and nuts are loose, especially in the host bolts and nuts should be strictly inspected, check whether all the access doors are closed tightly, adjust the fan and the host of the steering, the exhaust valve should be in the fully open position.
2, the starting order is to start the analyzer, then start the fan, and then start the host. After starting the host, should first add fine particles of material, then add the normal size of material, and then open the air volume valve, in order to ensure that the inlet does not spray powder out of the premise should be as small as possible under the premise of the exhaust valve; and then adjust the fineness of the finished product.

3, the mill in the use of the process, there should be a fixed person responsible for the care, the operator must have a certain level of technology. Before the installation of the operator must carry out the necessary technical training, so that it understands the principle and performance of the mill, familiar with the operating procedures.
4, followed by a period of time after the use of the mill should be overhauled, and at the same time on the grinding roller grinding ring shovel knife and other wear parts for overhaul and replacement of processing, grinding roller device before and after the use of the connecting bolts and nuts should be carefully examined to see whether there is a loosening phenomenon, whether the lubricating oil grease is added enough.
5, to master the correct shutdown method, before the shutdown to stop feeding in advance, about a while and so no remaining material in the mill bin this can be power off, stop grinding work, and then stop the fan motor, in order to blow the residual powder.
