Air-Swept Coal Mill For Coal Powder Preparation With High Grinding Efficiency
Air-Swept Coal Mill For Coal Powder Preparation With High Grinding Efficiency
Air-swept coal mill is an industrial equipment used for grinding and drying coal of different hardness. It is mainly used in cement plants, thermal power plants, building materials, metallurgy, chemical industry and other industries.
Technical Features:
- Drum mills utilize transmission types such as edge flyer, center drive, and multi-point meshing edge drive. Drive types include asynchronous motor + reducer + pinion + gear and synchronous motor + air clutch + pinion + gear.
- They generally utilize hydrostatic and hydrodynamic bearings at both ends, employing fully enclosed, self-aligning 1200 linear contact rocker-type bearings. Single or double-slider hydrostatic and hydrodynamic bearings, or full hydrostatic support, are also available.
- They are equipped with a reliably sealed gear cover and an automatic glycerin spray lubrication system.
- The drum, a key component of the mill, undergoes computer-based finite element analysis to ensure reliability.
- Large and medium-sized mills are equipped with a slow-speed drive.
- Large and medium-sized mills are equipped with high- and low-pressure lubrication stations.
- The control and protection system utilizes a PLC.
