Types Of Coal Mill Used In Cement Plant

In the cement plant, coal mill is used as pulverizer machine to crush coal into powder for cement manufacturing.

Pulverized coal is a common fuel in a cement plant. Due to safety reasons, monitoring of CO concentration in coal bunkers and coal mills is an essential issue. Increasing CO concentrations may indicate a smouldering fire and require immediate counter measures. In addition, O2 concentrations provide significant information for coal mills which are operated under inert gas purging: By monitoring the oxygen concentration during the grinding process the entrance of false air into the system can be detected at an early stage. Herewith the danger of explosion or fire can be minimized.

In the cement plant, there are several types of coal mills used.

SBM Coal mill for cement plant

Vertical roller mill is the main coal milling machine in cement plant, with large capacity, energy consumption and its fineness is up to 0.0445mm. In the complete cement production line, vertical roller mill is used in three processes.

In cement plant, Vertical Grinding Mill is very important since most of the raw materials will have to be crushed before being used to process cement, such as limestone, clay, iron ore and coal, etc. Limestone is the largest amount of raw material during cement production. Limestone is generally of large size and high hardness. Therefore the limestone mill is very important in the whole cement plant.

Ball Millis are widely used as coal mill in cement industry, chemical industry, new building materials, fire-resistant materials, fertilizer, porcelain and glass industry for grinding iron ore, gold ore, concrete, slag, zinc, copper ore, tantalite, etc. It has two ways of grinding: dry process and wet process. The hollow axis adopts the cast steel, and the lining can be replaced. The big rotary gear is forged from cast rolling gears.The barrel body is inlaid with wearable plates,so ball mill has long serve life.The ball mill runs steadily and efficiently.

Rolling Coal Mills provide coal for efficient burning. The mills grind the coal into small uniform particles.

SBM Coal Pulverizer mill

SBM coal pulverizers include two major series : cement crushing serie and cement grinding serie.

Jaw crusher can process raw materials with capacities varying from 1-5t/h to 400-1000t/h. their output size can be 10~40mm to 150~300mm.

Cone crusher : We provide CS Series cone crusher, HPC cone crusher,HCS90 cone crusher,Spring cone crusher.cone crusher can process raw materials with capacities varying from 27-91t/h to 454-559t/h. their output size can be 3~13mm to 31~64mm.

SBM is coal mill manufacturer in China, and offer types of coal pulverizer and coal mills for cement plant. we can realize the role of reducing energy consumption. Relatively speaking, using cement grinder mill to grind cement raw material, coal and blast furnace slag has been fine for the mature technology. As long as we control the cement particle size distribution, water demand, the types of ingredients in the gypsum and grinding temperature and so on, to achieve large-scale promotion of thecement cement grinder mill use is very promising.
