cement homogenising raw mill

Cement production - 3D scene - Mozaik Digital Education and Learning

Cement is a binder, a finely ground, inorganic substance.When mixed with water, a chemical reaction takes place between its components, producing a hard, stone-like substance that is insoluble in water.Cement is a component of concrete; therefore it is widely used in the construction industry.. The most important raw materials for cement production are limestone and clay.

Fire and Explosion Hazards in Cement Manufacturing Industries

Coarse material is returned to the grinding mill and fine particles (raw mix) are blended in homogenizing silos. Homogenization takes places when air entering the bottom of the kiln passes through the raw mix fed from above. Raw mix is heated up to 800C by kiln waste gases in a multi-stage cyclone pre-heater before it enters the kiln.
