\The usage, principle and main structure of Ball Mill

USAGE: Ball Mill is the key equipment after the material been broken, and continue to be crushed. It is widely used in cement, silicate products, new building materials, refractory material, chemical fertilizer, black and non-ferrous metal separation and glass ceramics production industry.

PRINCIPLE: Horizontal cylinder rotating device, edge transmission, three warehouse ball mill. Used for open flow grinding system, grinding of different label cement clinker, super fine powder or cement products. The material by feeding device through the hollow shaft spiral evenly into the first storehouse, namely the coarse grinding storehouse, this storehouse (and two warehouse) has high ladder type ring ditch lining board (material is high manganese steel), Larger average diameter of grinding medium is installed inside, cylinder body rotating produces a centrifugal force takes the grinding medium to a certain height and then down, and produces thumping and abrasive for material. The material in the first storehouse reached coarse grinding, through the single segregation warehouse into the second device storehouse, the diameter of grinding medium (ball) in this warehouse is less than first storehouse, and the material is continue to be crushed, and then after arc model choose powder type double screen in the warehouse of the device screening, coarse material to return to the second warehouse, fine particle materials into the third class, that is fine grinding warehouse. Fine grinding warehouse used in ripple lining board (material which is element chilling alloy), inside packs miniature grinding medium-small steel forging. The material in this warehouse by grinding, in order to eliminate far away from the cylinder body parts of the tiny stagnation area and three warehouse were more easily appeared contrary grading phenomenon for grind body, in three warehouse has 3-5 way activation device, further improved the forging of the storehouse grinding efficiency. Qualified products and miniature forging into the discharging device at the same time, through the material ??board realized the forging separation from the material, products of cement discharged by the out-put hollow shaft and eventually finished the grinding out work.

MAIN STRUCTURE: The grinding machine including motor, reducer, slow drive, power distribution control cabinet, feeding device, main bearing, rotary body, discharging device, transmission parts, lubrication system (mainly including high pressure pump station and low pressure thin oil station) and other major parts. Hollow shaft with steel castings, lining systems can be replaced, return big gear uses the straight teeth, cast steel material, roll teeth processing. The cylinder body set have high chenban manganese steel and alloy element chilling wear resistance linings, good resistance to impact and abrasion resistance. This machine is smooth operation, reliable. Internal structure can be adjusted according to customer requirements.

\Classification and feature:

1, Ball Mill is applicable to all kinds of ores and other grinding materials, widely used in mineral separation, building materials and chemical and other industries, it can be divided into dry and wet type two kinds of grinding way.

2, According to the different way of grinding, it can be divided into open flow and circle flow.

3, According to the length diameter size of mill tube, it can be divided into: short grinding, medium-long grinding, long grinding (also called tube mill, the internal generally divided into 2-4 warehouse . In the cement plant used morer) 3 kinds.

4, The feature of Tube Mill is high crushing scale, namely that product is fine, a strong compatible to material, fineness of product is easy to adjust, and easy to large-scale. So it is widely used in cement industry.
