temperature causes the raw material to react and form a hard nodular material called “clinker”. to storage and then to the finish mill is similar to that used to transport raw materials (e.g. belt additions of approximately 5 percent gypsum to control the setting properties of the cement can be done in ball mills, ball mills in
Water Spray in Cement Mills. Water spray installed generally in second compartment of ball mill to control cement temperature. Cement discharge temperature should be kept below about 110 o C but, the same time should allow some 60% dehydration of gypsum to optimize cement strength without excessive false set.

Coal Ejection Pipe calcinates and releases much heating. The heat in kiln is transferred to clinker cement by flame radiation, heat convection, and bricks transmission. Clinker cement moves forwardleaning on cylinder’s inclination and rotation of kiln. The max temperature of cement kiln can be 1600℃.

This modification involves the construction of a new dry process Portland cement manufacturing line (Kiln No. 6) capable of producing 1,405,104 short tons per year of cement clinker. The modification includes raw material handling and storage, kiln feed preparation with an inline raw mill, a dry process rotary kiln coupled with preheater and
The stateoftheart of both technology and operational practice of a hot rolling mill are discussed. The focus is first on the control of entry temperature in the finish mill. Transfer bar
Deforming a transfer bar with such inhomogeneous temperature profile will have a negative influence on the resulting microstructure. It is therefore necessary to allow time for temperature homogenisation before entering the finishing mill. An alternative way to control the entry temperature of the finishing mill is by induction heating.
38]. Various grinding laws, energy relationships, control factors and controller design for cement grinding are discussed in [37]. Figure1. Vertical roller mill for cement grinding [13].
