Application Scope and Use of Coarse Grinding
1.) Application scope
Coarse grinding mill is mainly used in these areas, such as metallurgy, building, chemical, mining industriy, etc. It can grind a variety of non-explosive and non-flammable brittle mining materials, whose Moth's hardness is below 9 grade, such as quartz, feldspar, calcite, marble, porcelain, ironstone, copper ore, coal gangue, phosphate ore, granite, basalt, carborundum, corundum, heat insulating material and so on.
2.) Usage
Generating station to desulfidation: according to client's need, coarse grinding mill could be equipped with vibrating screen and could grind limestone into fine powder below 2mm or 1mm.
Quartz sand (silica sand, casting model powder, etc.): the fine sand from 0mm to 3mm can reach to 70% of the product.
Coarse powder mill: if it is used as coarse powder mill before ball mill, this machine can increase the efficiency of the ball mill by 50%.
Firebrick, baking-free brick, building blocks: the powder produced by this machine is the best mixture material for making baking-free brick and hollow building blocks.
Coarse powder: Equipped by vibrating screen, this machine's volume of production can be increased, 130-140% higher than normal Raymond mill.

2. Technical Features of Coarse Grinding
1.) It serves several purposes: this machine can produce the materials of various particle sizes after it constitutes the closed production line with auxiliary equipments.
2.) High efficiency: its efficiency of producing powder and fine sand is higher than ball mill, Raymond mill, vertical mill, etc.
3.) High operating factor of the abrasive materials: even wear of the plates avoids the trouble that rolls must be changed when the middle is sunken in the Raymond mill.
4.) Low fault rate: the special plate structure and seal make it more stable and longer service life than Raymond mill.

4. Main Structure and Working Principle
1).Coarse Grinding mill mainly consists of frame, rotor, impact plate, grizzly bars and other components. The frame includes upper part and lower part, which are welded by steel plates after cutting. The remaining parts are connected into an integrated one by bolts. Hard-wearing side plates are installed inside the frame. It is easy to replace them when they are worn. On the main shaft are installed several groups of the blow bars with even weight, which are fixed tightly by high-strength bolt.
2).The host drives the main shaft through the electric motor and V-belt, thereby making the rotor rotate. The bulks of material fed into the crushing chamber will be crushed by the hammers at a high-speed movement. The qualified broken material will be passed the grizzly bars at the lower part
