Generally speaking, the cement industry production of Portland cement, Portland cement is a kind of meticulous, usually in the form of gray powder, it is composed of calcium (from limestone), silicate and aluminate (clay) and the composition of ferrite. In a silicate cement plant, cement production technology mainly has the following process:

stone crushing production line

1. Crushing And Homogenization

(1) the cement production process, a large part of the raw material to be broken, such as limestone, clay, iron ore and coal, etc. Because the limestone is one of the largest raw material consumption in the process of production, out of the ground after the larger particles, hardness is higher, so the limestone crushing in cement material crushing occupies more important position. Commonly used limestone crushing equipment are jaw crusher, impact crusher, cone crusher and so on.

(2) the raw material is the field in save, take the process of raw material, the use of material piling and taking scientific technology, to achieve the initial homogenization of raw material, make the raw material yard and the function of storage and homogenization.

2. Raw Meal Preparation

Cement production process, each producing one ton of Portland cement grinding at least 3 tons of materials (including all kinds of raw materials, fuel, clinker, gypsum, mixture), according to the statistics, dry process cement grinding operation equipment production line need to consume power accounted for about 60% of the entire factory power above, of which more than 30% of raw material grinding, grinding coal accounts for about 3%, accounted for about 40% of cement grinding.

3. Raw Meal Homogenization

NSP cement production process, stable raw ingredients pit entry is stable, the premise of clinker burning system in raw meal homogenization system plays a stable raw ingredients pit entry of a final checks.

4. Preheat Decomposition

Preheat and part of the raw decomposition are done by preheater, instead of rotary kiln features, to shorten the length of the rotary kiln, kiln at the same time heat transfer process of the gas accumulation condition material, moved to the inner state of suspension preheater into line, slurry is able to discharge of hot gas well blended with stove, gas increases the contact area, heat transfer speed, high heat exchange efficiency, improve production efficiency, reduce the clinker calcining kiln system heat loss.

5. Cement Clinker Burning

In the cyclone preheater with uncooked materials, after completion of preheating and precalcining is into the next procedure of complete sets of equipment, rotary kiln cement clinker burning. Clinker burning, temperature began to reduce. Finally by the cement clinker cooler will turn back to the kiln of the discharged high temperature clinker cooling to the downstream conveyor, storage library and cement mill can withstand temperature, recovery of high temperature clinker sensible heat at the same time, improve the thermal efficiency of the system and quality of clinker.

6. Cement Grinding

Cement grinding is the end of the cement manufacturing process, is also the most power consumption process. Its main function is to cement clinker (and gelling agent, performance adjustment material, etc. ) grinding to appropriate particle size (such as fineness, specific surface area), to form a certain grain size distribution, increase its hydration area, accelerate the hydration speed and satisfies the requirement of setting and hardening cement paste. For cement grinding, ball mill is the best choice.

Cement production process will use a lot of crushing grinding equipment. Such as limestone crusher and ball mill. SBM is a professional production of crushing and grinding equipment manufacturer, if you need, please contact us.
