Coal is called “black gold” which reflected its importance to human life. In fact, most of China’s power supply depends on thermal power. Hydro-electric power requires favorable location, and nuclear power is not safe enough, so only thermal power is the perfect and mature power generation by far. As coal-producing province, sand making machine production has had a larger impact to the country’s electricity supply, and air-swept coal mill and coal crusher can also benefit from it.
Efficient coal production requires select sand making machine production equipment. As the home of construction machinery, We province is also the cradle of mining machinery industry. Involved in mining machinery industry for more than 30 years, has grown into the top 3 mining machinery manufacturer in China. Focused on the mining industry, crushing machine and ore-dressing equipment has been the leader of mining machinery step by step through following market and technological frontiers. Compare with other equipment, the crushers have the following advantages: The maximum feeding size of the material can reach 1800mm and the discharging size can below 5mm. The gross investment of these crushers can save about 35%- 50% of the whole investment. These crushers can save the operation costs about 30%-40% when compare with other crushers. The floor space of this equipment can save about 40%-60%. The long services life of the wearing parts can reduce the maintenance times and costs.
Take an example of air-swept coal mill, Vertical Roller Mill is used for grinding and drying of coals with various hardness, mainly consists of feeding device, main bearings, rotating parts, gear, feeding devices, high voltage starting and lubrication system, so it is widely used in the cement and building materials, thermal power generation, metallurgy, chemical industry and other industries. Air-swept coal mill is a kind of grinding machine driven by electric motor through reducer and gear. The air-swept coal mill uses wind-sweep-type structure with a drying storehouse, making it has greater adaptability of coal. Feeding device is oblique inlet shutter-type structure, which enhances thermal exchange capacity of the grinding mill, can effectively prevent the blocking of imports of coal mill.
