Coal Mill

coal millcoal mill working principle

In thermal power plant, coal mill pulverizer is used in the milling process to crush and grind coal into powder. SBM offer types of coal mill for powder plant.

Type of coal mill

Ball mill is the early coal grinding mill used in coal powder plant like cement plant and thermal powder plant. In the coal handling plant, ball mill is used for grinding coal into dust with fineness 0.074 mm- 0.4mm. There are two types: wet ball mill and dry ball mill. This type coal mill performance is rather good:

  1. the output is high
  2. the maintenance is friendly
  3. the operation is easy
  4. safety control

Vertical mill is the most common coal grinding mill in milling plant, so vertical mill is also called vertical coal mill, it set up the coal mill stardard. In the thermal powder plant, coal is ground into pulverized coal by vertical roller mill, is then generally used in a fossil fuel power plant for electricity generation.

Raymond mill is also the coal mill pulverizer, the capacity can be up to 6-8 t/h. Raymond mill can be used grinding coal into powder with finess from 100 mesh to 325 mesh according to the requirements. Raymond roller mill is also used in mining, construction, chemical industry, such as barite, calcite, feldspar, talcum, marble, limestone, clay, glass.

Hammer crusher is coal mill used before grinding process. It can create coal dust by the crushing, grinding, or pulverizing of coal, and widely used in coal mining, handling plant. The Standard Hammermill Crushers are used in cement, aggregate and mining industries. Its large feed opening, superior impact crushing power and high reduction ratio make it a good choice for single-crusher operations.

Coal mill manufacturer

SBM is a professional coal mill manufacturer in China, and supply coal crushers, coal mills, coal washing, screening, and pulverizing machine for sale with best price. We also can design coal milling solution according to the special requirements for powder plant in South Africa, USA, Australia, Indonesia, India, Japan, New Zealand, Philippines, Malaysia, Pakistan, Germany, Zimbabwe, Kenya.

Coal mill process

Coal is mined by explosion, then crushed by coal crusher into small pieces. In this coal crushing process, several types of coal crusher are used. Jaw crusher, impact crusher, cone crusher can be used as coal pulverizer.

After crushing, crushed coal enter into the coal mill for grinding. Usually a complete coal milling line includes coal mill, impulse dust cleaner, piping device, cyclone collector device, classifier. The coals are squeezed by roller and ring into powder, the powder is collected by cyclone collector. In order to ptotect the environment, we also install the cloth deduster.
