Several Kinds Of Coal Crusher Equipments

In order to solve the problem of small coal mine area and inconvenient transport of equipments

, based on 20 years' production experience and several years' research, manufactures the world-class high-quality crawler type mobile crushing plant. It is made by impact crusher, jaw crusher, cone crusher, vertical impact crusher, conveyor, belt conveyor etc. It can meet different requirements "screening after crush" and "crush after screen". The crushing process can be divided into two phases "coarse and fine", and three phases "coarse, middle and fine". Moreover the mobile crushing plant can operate independently and jointly with great flexibility.

Vertical coal mill

Vertical coal mill is the ideal substitute of the traditional grinding mills like raymond mill, high pressure suspension grinding mill, ball mill, etc. It's been widely applied for coal mill. Apart from coal crushing, vertical coal mill is also widely used in such industries as cement making, power, metallurgy, chemical industry, non-metallic mineral. It is used to grind granular and powdered materials into powder with required fineness.

Coal mill operation

To make good coal mill operation, it's better for you to learn about vertical coal mill working principle : The motor drives the grinding table through decelerator. The materials fall down the center of grinding table from feed opening. At the same time, hot air comes into the mill from the air inlet. Due to the centrifugal force, materials move to the edge of the grinding table. The materials are pulverized by the roller when passing the groove on the grinding table. The crushed materials are brought up by high-speed airstream, the larger particles fall down to the grinding table for regrinding. When the materials in the airstream pass the separator on the top of the mill, the coarse powder fall down to the grinding table for regrinding by the rotor. The fine powder comes out with the airstream, and is gathered by the dust catcher. The materials content with moisture will be dried when they meet the hot airstream. Through adjusting the temperature of the hot airstream, it can meet different materials' requirements, and through adjusting seperator, it can reach proper fineness of materials

Brief flow of coal crusher plant

The general hardness of coal is 1-4. After coarse coal crushing by jaw crusher, fine coal crushing by impact crusher, and sieved by vibrating screen, coal can be processed and crushed into different sizes of the requirements. Hongxing jaw crusher, impact crusher for coal crushing have been widely used in the coal industry and mining industry, for its high and unique quality. They can crush coal at large quantity and high efficiency. In addition, vertical coal mill can further crush coal into much smaller sizes to meet specific requirement

With its high quality products such as Secondary cone crusher, Mobile jaw crusher, Sand maker, Dryer machine, Henan Hongxing mining machinery Co.Ltd has ascended in the front rank of the world in the exporting of mining equipments.
