The cement clinker grinding is the last step of the cement manufacturing process, in this step, cement mill grinds cement clinker, gelatinizing agent and other materials into the required size, which can meet the requirement of cement. Clay is used as an argillaceous component of raw mix. As a parameter in kiln control, free CaO data is somewhat ineffective because, even with fast automated sampling and analysis, the data, when it arrives, may be 10 minutes "out of date", and more immediate data must be used for minute-to-minute control. WebABB is a leading global supplier of medium voltage drives in the range of 200 kW to more than 100 MW. Contact temperature measurement is impossible because of the chemically aggressive and abrasive nature of the hot clinker, and optical methods such as infrared pyrometry are difficult because of the dust and fume-laden atmosphere in the burning zone. There are two main kinds of cement kiln to manufacture cement clinker. This kiln currently relies upon coal for its heat energy.
