What is loi of cement raw materials

Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products The lumps or nodules of clinker are usually of diameter 325 mm and dark grey in color It is produced by heating limestone and clay to the point of liquefaction at about 1400°C1500°C in the rotary kiln
