Apr 13, 2020 The manufacture of Portland cement is a complex process and done in the following steps grinding the raw materials, mixing them in certain proportions depending upon their purity and composition, and burning them to sintering in a kiln at a temperature of about 1350 to 1500 ⁰C. During this process, these materials partially fuse to form nodular shaped clinker by broking of chemical.
Crushing in cement production. The first procedure for producing cement is to break up raw materials and limestone is the main raw material for cement production Since the limestone is mined and the hardness is high the jaw crusher that specializes in crushing limestone becomes a better raw material crushing equipment on the cement production line The jaw crusher has many advantages to prove.
Materials are extracted quarried recovered and transported to the cement plant. 2 Crushing and milling. The raw materials, limestone, shale, silica and iron oxice are crushed and milled into fine powders. 3 Mixing and preheating. The powders are blended (the ‘raw meal’) and preheated to around 900 C using the hot gases from the kiln.

Cement plant can be set up with vertical mill system for drying and grinding raw materials. The three-fan system consisting of preheater fan, raw material fan and kiln exhaust fan makes the system operation control convenient and flexible, and easy to produce stably.
Cement crusher plant used in cement production line. Cement crusher is the important cement machine used in cement production line. General it is used in cement crushing plant. Big raw materials firstly are crushed by cement crusher, then appropriate raw materials dust enter into the cement mill for milling with stone milling machine.
CRUSHING TRANSPORTATION 1. BLASTING The raw materials that are used to manufacture cement (mainly limestone and clay) are blasted from the quarry. 2. TRANSPORT The raw materials are loaded into a dumper. 3. CRUSHING AND TRANSPORTATION The raw materials, after crushing, are transported to the plant by conveyor.
The raw materials (limestone and clay) are subjected to such processes as, crushing, drying, grinding, proportioning, and blending or mixing before they are fed to the kilns for calcination or burning process. The crushing stage involves breaking the raw materials into small fragments that vary in size between 6-14 mm. Machines called Crushers.
Two separate Cement Production lines can be summarized into the following processes as can be seen in the process and Quality flow diagram below 1. Quarrying and Crushing 2. Raw material Storage and Transportation 3. Proportioning 4. Raw material Grinding and Transportation 5. Raw meal storage, homogenization and Kiln feeding 6.
