Coal milling plant for coal mining

Home > Non-metallic Ore Crusher > Coal milling plant for coal mining

Usually we grind coal into powder to improve the using efficiency. This way is common in Electric Power Plant. In this milling process, coal mill plays an important role.

Coal mill has many kinds, such as ball mill, raymond mill, vertical mill, ultrafine mill etc.

Ball mill is most widely used coal mill. It is suitable in the powder plant, and widely used in powder-making production line including cement, silicate, new-type building material, refractory material, fertilizer, ore dressing of ferrous metal and non-ferrous metal, glass ceramics, etc. It is divided into two rubbing way-the dry and the wet. There are two kinds of ball mill, grate type and overfall type due to different ways of discharging material. The ball mill is a key equipment to grind the crushed materials after the material were broken , and carrying on the smashing again.

Vertical Mill is a kind of large scale powder mill which is designed specially to solve the problems of low capacity and high consumption of industry mills. With a decade of years research of mills, vertical mill is designed and manufactured based on our advanced design idea, and in combination with the european technology and the market demand. LM Vertical Roller Mill adopts reliable structure and reasonable process flow, integrated with drying, milling, classifier, elevator. Especially, it can fully meets the requirement of clients in the high production of powder, and its main technical and economy indicator reachs the international level.

Raymond mill is the early coal mill, all the finished particles have a good uniformity of finess, with passing screen rate as high as 98%. This is what other machine can not reach.

Ultrafine grinding mill is a equipment which produces thin powder and super thin powder. It will highten pollution and noise by using deduster and muffler, which achieves environmental protection requirement.

Coal milling process

A complete coal milling plant not only includes coal mill, but also other machines such as hammer crusher, hopper, deceleration machine, blower, dustpan elevator, electro-magnetic vibrating feeder, impulse dust cleaner, piping device, cyclone collector device, classifier, high-pressure moto and muffler.

Coal is grinded into powder in the coal mill, the fine particles will come into the cyclone collector with the airflow, and be discharged by the discharging value on the bottom of the collector. They are the final products. The airflow with little dust will be discharged through blower and muffler after being purified by the cyclone collector.
