Cement Manufacturing Process Phase II: Proportioning, Blending & Grinding. The raw materials from quarry are now routed in plant laboratory where, they are analyzed and proper proportioning of limestone and clay are making possible before the beginning of grinding. Generally, limestone is 80% and remaining 20% is the clay.
There are three steps of the high-temperature system: Drying or preheating, calcining, and sintering. The calcining is the core part of the clinker production; the raw meal is weighed and sent into preheater and cement kiln to process clinker. Grate cooler helps to cooler clinker, the cooled clinker is sent to the cement silo for storage.
Any manufacturing process includes series of operations. Cement production process primarily includes 3 stages. Raw material mining/extraction and transportation. Material processing. Proportioning, blending and grinding. Preheating. Kiln. Cooling and final grinding. Packing and shipping.
