Steel Ball Coal Mill
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 Steel Ball Coal Mill 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.
Function
Steel ball coal mill could be used in the cement industry, metallurgical industry, chemical industry, sugar industry and other powder preparation system as well as iron powder production line.
Principle of Operation
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 Steel Ball Coal Mill 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.
