Kaoline enter into kaolin crusher for crushing, after primary crushing by hammer crusher, it"s diameter is about 25mm. Then crushed kaolin go through secondary crushing by cage crusher until it"s diameter is less than 6mm, the final step is grinding. Usually use raymond mill to grind kaolin into powder. The kaolin clay after processed this method is usually used as Packing in rubber, plastics, Papermaking industry.Compared with other grinder machines,especially vertical mill, the grinding ball Mill is of quite simple structure. the ball mill is made up of feeding part, discharging part, gyre part, transmission part (reducer, small transmission gear, motor, and electrical controller) and so on. The hollow axis of Ball mill adopts the cast steel, and the lining can be replaced. The big rotary gear is forged from cast rolling gears. The barrel body of the Ball mill is inlaid with wearable plates.Raw calcite to commence with enter calcite crushing plant to get crushed to more compact sized dimension. The calcite crushing plant is composed of jaw crusher, cone crusher, impact crusher, belt conveyor, vibrating display and vibrating feeder. Then they are actually lifted to storage spot by elevator. Vibrating feeder will feed factors into calcite grinding mill evenly and progressively. Following at present currently being grinded, the calcite powder is going to be blowed to cyclone by blower. Then the calcite powder is heading to be transferred to storage room by pipes, following which will be discharged as closing solutions. Often the crushing system isn’t essential, often grinding system of action is not necessary. Construction industry (dry mortar, concrete) heavy calcium powder-Heavy calcium carbonate powder mortar (heavy calcium powder) 325 mesh, white degree requirements: 95%, calcium carbonate content: 98%. Calcium carbonate in the concrete in the construction industry plays an important role in not only reduce production costs, it can increase the toughness and strength of the product.marble grinding mill: http://www.china-stone-crushers.com/equipment/21.html
