Mining equipment

Coal mine machinery and equipment is a large mechanical equipment dedicated to mining, transmission and transportation in coal mines, including mining machines, conveyors, shaft and roadway driving equipment, underground auxiliary transportation, vehicle equipment, mine winch, ventilation and dust removal equipment, coal washing equipment, cranes, special vehicles and so on.

Mechanical equipment in coal mine production has the following characteristics:

1, the working conditions are harsh, most mechanical equipment is in high speed, heavy load, vibration, impact, friction and medium corrosion working conditions.

2, poor lubrication conditions, due to the harsh environment, harsh working conditions, coupled with short downtime, which makes mechanical parts not good lubrication and maintenance.

3, the working environment is harsh, the equipment is always surrounded by dust, water vapor and harmful gases.

4, the operation time is long, most of the mechanical equipment day and night, continuous operation for years.

Only through the selection of the correct bearing, regular maintenance, timely maintenance, improve the quality of maintenance, to ensure that all production equipment in a good state of operation, is to reduce the wear of coal mining machinery, extend its service life, to achieve high-yield, efficient and safe production of coal effective measures, mining operators can ensure higher productivity, so that the equipment to achieve the expected service life.
