The selection of the vertical roller mill is based on the speed of the motor to drive the rotation of the rotating wheel and the formation of the vortex effect of the powder on the role of the. The speed of the blade is adjusted according to the size of the particle size of the product. To obtain a more fine-grained powder midnight, raise the blade speed, the coarse powder due to its gravity drop into the grinding chamber of regrinding and qualified finished powder through the blade with the air suction to the cyclone dust collector in.
Vertical roller mill operation maintenance work is very important, do a good job maintenance work not only to extend the service life of the machine, but also to reduce the operating costs of the machine, but also to ensure that the machine's size of the uniform. Good machine maintenance, mainly to do the following aspects of the work: machine lubrication,replacement of wear parts and the fastening wear parts.
Vertical roller mill itself is the production of industrial equipment, the mass production of industrial dust will always be a certain degree of pollution in the machine. Dust pollution in the machine, the machine bearings and other parts of the consequences of pollution caused by the most serious, into the main city will cause the internal friction between the bearing increased, resulting in bearing heat, wear and a series of phenomena, and even cause damage to the machine. In order to prevent the dust with the serious pollution of the machine, we must do a good job in the lubrication of the mill.
There are two kinds of lubrication in the vertical roller mill operation process: rare and grease lubrication. Located in the vertical grinding mill reducer internal lubrication oil can be carried away by dilute oil bearing dust impurities and heat, the protection of bearing less dust pollution, while protecting the bearing to avoid heat damage. In the upper part of the vertical roller mill, the grease lubrication can reduce the friction between the bearings and reduce the damage probability.
The vertical milling machine is made up of many parts, such as the screw. The loose of any one of the fixed parts may cause the destruction of the mill. Hear abnormal noise in the mill work should also stop to check if there is a loose.
