Project introduction
The cement production line is mainly composed of crushing, homogenization, raw meal, drying, preheating decomposition, clinker firing, cooling, grinding, packaging, transportation, environmental protection and dust collection, etc. We provide cement production line process design, civil construction, complete sets of equipment, installation and commissioning, technical services, and general contracting of projects.
Equipment contains
The main equipment of the cement production line includes: cement rotary kiln, cyclone preheater, cooler, crusher, vertical mill,roller press,
cement mill, coal mill, dryer,
dust collector, packaging machine, bulk machine, conveying machine, electrical
control, etc.
Production method
Cement production uses limestone and clay as the main raw materials. After crushing, batching, and grinding by a vertical mill to make raw meal, it is then fed into the cement rotary kiln to calcinate the clinker, and then add an appropriate amount of gypsum to the clinker, and add some mixed materials or The admixture is ground into cement through cement milling, and is transported out of the factory by a packing machine or a bulk packing machine.
Synonym of cement manufacturing plant: cement production plant, cement production line, equpment for cement plant, OPC cement plant, portland cement plant, dry cement production process.
