Grinding of the clinker consumes about 1/3 of the power required to produce 1 ton of cem ent. This refers to an average specific power consumption o f 57 kW h/ton (W orrel et al ., 2002). The clinker is then cooled and ground to a fine powder in a tube or ball mill. A ball mill is a rotating drum filled with steel balls of different sizes (depending on the desired fineness of the cement) that crush and grind the clinker. Gypsum is added during the grinding process to provide means for controlling the setting of the cement.

Nov 29, 2019 After sintering, the clinker will have a high temperature. They will cool down at the end of the kiln firstly and then enter the cooler placed behind the rotary kiln for further cooling. When clinker drops to indoor temperature, it will go to the next step. Cement Grinding: cement grinding is the final stage in Portland cement manufacturing. In this step, clinker will be … The clinker is ground in a ball mill—a horizontal steel tube filled with steel balls. As the tube rotates, the steel balls tumble and crush the clinker into a super-fine powder. It can now be considered Portland cement.

The pyro processing of kiln feed produces cement clinkers. The hot clinkers are then cooled down and bucketed to store in clinker stockpiles. After this stage, the clinker and gypsum are mixed together and sent to the mill inlet for the further grinding process to form a fine grey powder. Aug 20, 2015 In this process, the chemical bonds of the raw materials are broken down and then they are recombined into new compounds. The result is called clinker, which are rounded nodules between 1mm and 25mm across. The clinker is ground to a fine powder in a cement mill and mixed with gypsum to create cement.
