Mine machinery and equipment is a kind of mining, transmission, transportation of large-scale machinery and equipment, including mining machines, conveyors, wells and alleys digging equipment, underground auxiliary transportation, vehicle equipment, mine winches, ventilation and dust removal equipment, coal washing equipment, cranes, special vehicles and so on.

The machinery and equipment in mine production has the following characteristics:

1. The working environment is harsh and the equipment is always surrounded by dust, water vapor and harmful gases;
Cement machinery and equipment include: crushers, crushers, grinders, vibration sieves, ball mills, sand production lines, stone production lines, washing
Sand machine, sand machine, feeder, cement rotary kiln (rotation kiln) wheel, etc.

2. The working conditions are harsh, most of the machinery and equipment are working under high speed, heavy load, vibration, shock, friction and media corrosion, etc.

3. Long running time, the vast majority of machinery and equipment day and night, year after year continuous operation;

4. Poor lubrication conditions, harsh conditions and short downtime make mechanical components less well lubricated and maintained. Therefore, the annual economic losses caused by the amazing, only by selecting the right bearings, regular maintenance, timely maintenance, high maintenance quality, to ensure that all production equipment in good condition, is to reduce the wear and tear of coal mining machinery, extend its life, to achieve high coal production and efficiency and safe production of effective measures, mining operators can ensure high productivity, so that equipment
Reach the expected service life.
