Advantages
High grinding efficiency
For the structure, of the cement mill, we adopts the advanced obstructing equipment for internal powder, add the activated device to the fine grinding chamber, and there is the special grate plate at the end of the cement mill, which can reduce the size of the grinding medium, greatly improve the grinding efficiency, and achieve the purpose of high output and low energy consumption.
Energy saving and environmental protection
The cement grinding unit has advantages of simple structure,strong controllvability, and easy to operate or maintain. The discharge concentration is less than 50mg/Nm3, lower than the discharge standard, and protect the environment of the production site effectively.
Good quality of finished products
The production process overcomes the disadvantages of traditional equipment. The fineness of product is easy to be adjusted, apply for different requirement of fineness. The equipment also has advantages of large heat dissipation area and low temperature inside mill. The finished product of new-type cement grinding unit has high quality and large capacity.
High output, large handling capacity
Compared to other production process, with same feeding size and other working conditions, our cement grinding unit can increase capacity by 30%, and the energy consumption can be reduced by 15%.
Technology
Batching: The shipping clinker is discharged into the dock crane and then transported to the clinker warehouse. After unloading at the bottom of the tent warehouse, it is transported to the clinker batching warehouse. Gypsum and slag are transferred from the loader to the crusher for crushing and then hoisted into gypsum and slag storehouse respectively.
Weighing, mixing and feeding cake: After battering the bottom of the warehouse, it will be sent to the stable flow weighing bin of the cement mill by the belt conveyor, and an iron remover will be arranged on the conveyor. The materials are mixed and stabilized in the steady flow weighing bin, and then fed into the cement roller press uniformly and continuously in the form of a material column. After the material passes through the high pressure, the physical structure is destroyed, forms the material cake and it will be raised by the hoist feeding classifier.
Grading: The classifier breaks the cake and grades it, and then separates the fine powder less than 6mm from the coarse powder more than 6mm. The coarse powder is returned to the stable flow weighing bin of the cement roller press, and then extricated again, and the fine powder is fed into the cement mill. After the fly ash is measured by the reamer scale, it goes through the chute into the hoist and feeds directly into the cement mill through the chute and the feeding chute.
Grinding: after cement mill grinding, materials enter into the powder separator, the fine powder is sent to the cement silo by the air transmission chute and the elevator, the coarse powder back to the cement mill to continue grinding. One part of the outgoing cement is controlled by the bottom unloader of the fluidized warehouse, and then through the air conveying chute and the elevator, sent to the packaging machine room for delivery, while the other part is sent to the bulk carrier for delivery by the air conveying chute.
