— This research focused the role to study the effects and ways to control the chemical composition of clinker for better cement production Cement is a substance produced by grinding a mixture of a clay and limestone and heating to a temperature of 1450°C in which the chemical transformation occurs inside the kiln to form new
WhatsApp
— Large clinker nodules Figure 2 are difficult to cool transport and grind into cement Clinker should ideally have a smaller average nodule size and a narrow nodule size range More uniformly sized clinker is more evenly distributed into the cooler and has more consistent bed porosity which enables more stable cooler and kiln operation
WhatsApp
— Samples of the input output and return material of cement clinker grinding by a CKP mill are collected based on the field sampling in the industrial mill The crushing kinetic process of the cement clinker in a CKP mill is analyzed by using the particle size distribution and mass balances The following results have been obtained 1
