Overview

Coal Mill Introduction

Coal mill is an important auxiliary equipment for coal-powder furnace, it has three methods to crush the coal lump and grind them into powder,it is crushing, impacting and grinding.
Air swept coal mill is the main equipment in cement plant for both drying and grinding of the powders. Compared with the ordinary ball mill, it has advantages of higher capacity, more convenient operation, safer usage, and more reliable performance.
Coal mill is used to grind, pulverize and dry coal before the coal is transmitted the boiler. The coal is feed into the coal mill via a inlet pipe so that the roller coal mill such as ball mill or vertical mill can pulverize the coal into particles.

Coal Mill Working Principle

Coal mill is a horizontal rotating device transmitted by the outer gear. The materials are transferred to the grinding chamber through the quill shaft uniformly. There are ladder liner and ripple liner and different specifications of steel balls in the chamber. The centrifugal force caused by rotation of barrel brings the steel balls to a certain height and impact and grind the materials. The ground materials are discharged through the discharging board thus the grinding process is finished.

Benefit

Features of Coal Mill

1.Using large diameter double row spherical roller bearing, reduce friction, reduce the energy consumption of 20-30%.
2.End cover structure, large caliber inlet and outlet, the processing capacity is increased by 15-20%.
3.simple structure, split installation.
4.without inertial impact, the equipment runs smoothly, and reduces the downtime of the mill shutdown and improves efficiency by 15-25%.
