steel ball mill

steel ball mill is the main equipment of coal preparation system of thermal power station. Can also be used in cement industry, metallurgy industry, chemical industry, sugar industry of powder system, is widely used to crush the hardness of coal.

brief introduction

Its role is to a certain size of coal drying and crushing and grinding is made to supply the pulverized coal boiler combustion. The steel ball mill is widely used in domestic and international power plant, according to statistics, in the domestic power plant steel ball mill coal accounted for above 60% of the total amount of coal mill. However the disadvantage of steel ball mill is obvious, such as complex operation, high power consumption, big noise, steel consumption, multi wear etc., especially automatic control difficult to achieve this problem has not been effectively resolved, most power plants still in manual mainly. steel ball mill coal machine is an important equipment of power plant the safe and economic operation and the power plant safety, economic operation has a close relationship, so there is a need of steel ball mill coal machine properties and the existing control scheme for in-depth analysis to find out the steel ball mill coal machine automatically input rate is low the root causes.

Coal mill is a mill a, steel ball coal mill introduced steel ball coal mill is one of the thermal power station auxiliary equipment, the pulverized coal preparation system equipment is a theme, this series of steel ball mill is mainly used in the pulverized coal hardness of coal mill.

working principle

steel ball mill

The coal and coal mill is broken into a coal machine, it is an important auxiliary equipment of pulverized coal furnace. Coal grinding process is a process of the coal is broken and the surface area increased. Coal is pulverized coal in the coal grinding mill, mainly through crushing, crushing and grinding in three ways. Coal mill by grinding coal working parts can be divided into low speed coal grinding machine, medium speed mill and high speed coal mill.

purpose

Coal mill grinding coal machine is widely used in cement, silicate products, new building materials, refractory materials, chemical fertilizer, black and non-ferrous metal processing, glass and ceramic industry, for all kinds of ores and other materials may be grinding of dry or wet grinding.
