A cement mill is a type of ball mill used to grind materials into fine powder. It is employed for grinding cement, limestone, gypsum, fly ash, clinker, bauxite, and similar substances. The complete cement milling plant comprises a ball mill, bucket elevator, air classifier, screening machine, and other components.
Application fields:
cement, silicate, new construction materials, refractory materials, chemical fertilizer, black and non-ferrous metal dressing, glass and ceramics industries.
Adapted material:
fly ash, limestone, quartz, aluminum powder, coal powder, steel slag, ore, potash feldspar, iron ore, iron slag, aluminum slag, silicon carbide, alumina, coal gangue, etc.
The cement ball mill is one of the core pieces of equipment in a cement production line, undertaking the critical task of grinding materials such as cement clinker, gypsum, and blended materials to the required fineness to form the final product—cement. It directly impacts cement output, quality, energy consumption, and costs. Cement plants primarily use ball mills to grind clinker and gypsum into the fine powder required for cement production. The production process also involves grinding materials like slag, pozzolana, dolomite, and fly ash (using these mills) to add to cement for improved strength and durability.
A complete cement grinding station production line usually includes grinding, homogenization, packaging and other processes. Its typical process flow and equipment mainly include：
(1)Crushing and pre-grinding: First, crush the clinker into smaller particles with a clinker crusher. Then, pre-grind it using grinding machines.
(2)Grinding: This is the core process. After pre-grinding, the material enters the cement mill (such as a ball mill) for fine grinding. This system has high output and low energy consumption.
(3)Powder selection: The ground material will enter the powder selection machine for sorting. The coarse powder will be returned to the mill for re-grinding, and the fine powder (qualified product) will be output as the finished product.
