First, the use of a ball mill, principles and main structure uses: Ball is the material to be broken, and then to smash the key equipment. Ball mill is widely used in cement, silicate products, new building materials, refractory materials, fertilizer, ferrous and non-ferrous metals and glass ceramics and other production industries. Principle: Kat strong hand ball mill is a horizontal cylindrical rotating device, edge drive, three positions mill. For open circuit grinding system, different grades of cement clinker grinding, fine powder or cement products. Material from the feed device into the compound evenly into the air shaft spiral mill first warehouse, namely coarse warehouse, the warehouse (and two positions) have high ladder-type ring groove liner (made of high manganese steel), built The average diameter of the larger grinding, rotating cylinder produces centrifugal force grinding a certain height After the fall, have severe impact on the material and abrasive. Coarse material in the first position, after single-compartment device into the second position, the positions are grinding (ball) diameter less than the first warehouse, the material in this continues to be crushed, and then through the arc sieve election Powder double compartment device screening, coarse materials return to the second position, fine particulate material into the third position, that is fine grinding compartment. Fine grinding compartment with small corrugated liner (made of white multi-element alloy), built-in micro-grinding - small steel forging. Material in this position by grinding, in order to eliminate the cylinder farther away from the site of the stagnation region and the micro-forging three positions of the grinding prone anti classification phenomenon in the three positions that has the 3-5 channel activator, to further improve the forging Position of grinding efficiency. Qualified products and micro-forging the same time into a feeding device, realized through the discharge grate plate forging material separation, finished cement is discharged by the completion of the quill shaft grinding operations. Main Structure: The mill includes motor, reducer, slow drive, power distribution control cabinet, feeding device, main bearings, slewing part, discharging devices, transmission parts, lubrication system (including high-pressure and low-pressure lubrication oil pumping station ) and other major components. Hollow axis adopts cast steel, lined with removable, rotary gear with straight teeth, cast steel, hobbing. Drum is equipped with high-manganese steel liner and white multi-element alloy liner wear, has good resistance to impact and abrasion resistance. The machine running smoothly, reliable work. Internal structure can be adjusted according to customer requirements.
