mining grinding ball mill for ore

mining grinding ball mill for ore is mainly used for crushing and grinding of the material can be widely used in cement, ore dressing, new building materials, refractory materials, chemical industry, glass ceramics and etc. production industry, for all kinds of ores and other materials may be grinding of dry or wet grinding.

mining grinding ball mill for ore installation

First inspection on the basis of the position of a preformed hole, installation height whether the installation and layout of line, line check the ball mill and the motor are lifting on the basis of, alignment based on pre pull center line, the seat bottom with change at the beginning of the shaped plate transferred to meet the technical requirements of the installation, and tighten the anchor nut, then carries on the foundation of the second watering.

To be the second poured concrete foundation in solid, fine ball mill, so as to meet the technical requirements of the installation, anchor nuts and tighten the ball mill, then fine tune motor to meet the technical requirements of the installation, and tighten the motor of anchor nut.

All the installation is completed, turn the handwheel by hand, shaft must rotate flexibly, freely portable. In case of the death card, must be re adjusted to meet the requirements so far.
