Cement, Hydraulic inorganic cementing material powder. After mixing with water into a paste, can be hardened in the air, or hardened in water better, and be able to sand, stone and other materials, firmly cemented together. Cement is an important building material, made with cement mortar or concrete, firm and durable, widely used in civil construction, water conservancy, national defense and other projects.

Cement production process, limestone and clay as the main raw material, crushing, batching, grinding into raw material, cement kiln calcining feeding mature material, add appropriate amount of gypsum (sometimes mixed with mixed materials or additives) Ground made.Generally have the following three steps:
(1) Raw material grinding
Sub-dry and wet. Dry closed operating system commonly used, that is after the raw materials mill grinded into the separator sorting, coarse grinding back again into the grinding operation, and most materials used in the drying and grinding mill simultaneously process, the tube mill with the equipment, the unloading and the roller grinding mill. Tube usually wet grinding, grinding, and other baseball back in time through the mill is no longer open system, but there is also curved screen with a grading machine or closed-circuit system.
(2) Calcined
Clinker calcining kiln and kiln equipment mainly two types of kilns for the production of smaller factories, large and medium-sized plant should adopt the rotary kiln.
(3) Grinding
Fine grinding of cement clinker grinding process usually used ring current (ie, closed operating system). In order to prevent the production of dust flying, the cement plant are equipped with dust collection equipment. Electrostatic precipitator, bag filter and cyclone dust collector such as is commonly used cement plant dust collection equipment
As China's production and export of milling machine manufacturers, Shanghai Zenith Production ball mill, Raymond mill, Vertical Roller mill,MTM trapezium mill,MTW trapezium mill and so on contributed to the world cement mill industry development.
