Cement manufacturing is a high volume and energy intensive process, and according to the authors in [6, 7], the price of consuming large amounts of nonrenewable resources and energy (principallyContinuous blending involves simultaneous feeding of the silo, overflow to a second silo and final discharge to kiln feed. Modern equipment generally uses continuous CF silos, each having capacity of more than 24-hours’ kiln feed and yielding a blending ratio (or ‘blending factor’) of 4-8, or around 2-3 for older silos.Raw milling and blending INFINITY FOR CEMENT EQUIPMENT

A significant amount of false air can also enter through the inlet seal, in the case of the raw mill . installed to use kiln gases to dry the raw material. The largest false air intake takes place through the kiln inlet B and outlet A seals, due to the large . diameter of the seal and the continuous kiln rotary motion. 4.The capacity of a single kiln system has reached 12,000 tpd. b) With automation, instrumentation and computer-aided controls, the man-hours per tonne of cement produced has come down to one or even less, thereby reducing the application of human discretion and increasing the dependence on electronic gadgets. c)Chemistry and engineering of the clinkerization process —
