Steel ball coal mill is a crushing machine which could change raw coal into coal powder as important equipment in the preparation system for coal powder for boiler. In the process of steel ball mill coal mill producing coal powder, hot air (or hot smoke) is used to dry the coal. Steel ball coal mills have a variety of types and can be divided into low speed coal mill, intermediate speed coal mill and high speed coal mill according to the rotation speed. Type of steel ball coal mill is mainly based on the kinds of coal, boiler type and load conditions.
After many times of renovating design, MTZ steel ball coal mill fully adopts the double-inlet & double -outlet coal mill technology, the product is widely used for coal pulverizing system pulverized coal preparation in the industries of power, metallurgy, building material, chemical and environment protection etc, especially applicable for the bituminous coal, meager coal with the poor grindability and negative-pressure pulverizing system of bituminous coal.
After multiple renovating designs, MTZ steel ball coal mills manufactured by EO have the advantages of less land occupation, low electricity consumption, steady running, easy operation, long service life of wearing parts and widely used for pulverized coal preparation system in the industries of power, metallurgy, building material, chemical and environment protection etc. The product is especially applicable for the pulverized coal preparation system. MTZ steel ball coal mills as the competitive products of EO in the last century have high market share in domestic market with thousands of productions.
Steel Ball Coal Mill Working Principle:
Steel ball coal mill, a kind of horizontal cylinder rotation equipment based on outer gear transmission, includes into two containers as a grate energy-saving ball mill. Materials firstly enter into the first container of the steel ball coal mill through the feeding hallow shaft by the feeding equipment in a helical and even manner. The first container is equipped with a staged or corrugated lining board, filled with steel balls of various specifications which may be lifted to a certain height under the centrifugal force caused by the rotation of cylinder and then fall down to impact and mill raw materials. After coarse milling, raw materials will enter into the second container through the single-layer diaphragm, which is embedded with flat lining board and filled with steel balls to further mill raw materials. After that, power will be discharged from the discharging grate plate, indicating the completion of milling.
Structure Features of Steel ball coal mill:
The ball mill is composed by the feeding device,discharging device,rotating device, transmitting device and some other components. The hollow shaft of the ball mill is made of steel-casting, the liner is detachable, rotary gear hobbing processing with hobbing casting, and the cylinder of ball mill lining with wear-resistant plate, which decide the ball mill of good abrasion resistance. Thus, the ball mill is stable to operate and reliable to work.
