Mining stainless steel ball coal mill for sale  

steel ball coal mill is the main equipment for coal power production system, it is also key equipment for drying and grinding coal in cement plant, it is mainly for wet process grinding.

application of steel ball coal mill

Steel ball coal mill is a quarter of heat power station auxiliary machinery and main-equipment of Pulverized coal preparation system, mainly used for grinding a variety of hardness of the coal. Also applies to coal of cement, metallurgy, chemical industry and the mineral raw material powder system.

features of steel ball coal mill

(1)To use the ball mill, the material to be ground is loaded into the neoprene barrel that contains grinding media.

(2) As the barrel rotates, the material is crushed between the individual pieces of grinding media that mix and crush the product into fine powder over a period of several hours.

(3)The longer the ball mill runs, the finer the powder will be.
(4) Ultimate particle size depends entirely on how hard the material you're grinding is, and the time how long the ball mill runs.

(5) For hard minerals, adopt Non-iron pollution design. Use alumina ceramics, quartz, silex and other special material for liner and grinding medium.

(6) Formed a closed system with classifier, negative pressure conveying and less dust.

working principle of steel ball coal mill

After washed and dried(humidity less than 1%), the raw mineral was crushed to less than 2mm by jaw crusher and hammer crusher, enter the hopper by bucket elevator, then to superfine ball mill through belt conveying system.

The ball mill crush, shatter and grind the stone by the rotation energy, and then the powder enter the classifier for the first classification, most of the big particle was separated, and the fine powder enters turbine classification level area for second classification.

After twice classifications, qualified fine powder was collected by powder collectors, while the coarse powder return to ball mill for secondary crushing and grinding.
