Cement Plant

Cement plant is used in cement production line, like Portland cement, which is essential raw materials for construction buiding. It is used for manufacturing cement from ingredients like limestone, coal, gypsum and alumina (bauxite).

cement plant process flow chart

In cement plant, ingredients for cement production go through the following several process.

1.Crushing and Preblending

In cement plant, most of the material need to be broken, such as limestone, clay, iron ore and coal, etc. Limestone is the largest amount of raw material in cement production, after mining the size of limestone is large, with high hardness, so the limestone crushing plays a more important role in cement plant.

2. raw material preparation

In cement plant, producing each 1 ton of Portland cement need grinding at least 3 tons of materials (including raw materials, fuel, clinker, mixed materials, gypsum). Grinding operation consumes power about 60% of total power in cement plants, raw material grinding takes more than 30%, while coal mill used in cement palnt consumes 3%, cement grinding about 40%. So choosing the right grinding mills in cement plant is very important.

3. raw materials homogenization

Adopting the technology of homogenization could rationally get the best homo-effect and afford an eligible production to the demand

4. preheating and precalcing

Preheater and calciner is key equipment for precalcing production technique.

5.burning cement clinker in a rotary kiln.

The calcination of Rotary Kiln is a key step of cement production , it makes directly influence on the quality of cement clinker.

6. cement grinding

Cement grinding is used for grinding cement clinker (and gelling agent, performance tuning materials, etc.) to the appropriate size (in fineness, specific surface area, said), optimizing cement grain grading, increasing the hydration area, accelerating the hydration rate to meet the requirements of cement paste setting, hardening.

7. cement Storage & packing

Portland cement plant

Portland cement is the most common type of cement in general usage in many parts of the world, as it is a basic ingredient of concrete, mortar, stucco and most non-specialty grout. The cement is produced by grinding raw clinker which is making by Limestone, Clay, Coke and Gypsum. The grinding of cement clinker is a straight forward process. The clinker is put to feed hopper, which in turn feeds into the pre-crusher. Then the table feeders extract it out from the pre-crusher and put it into the ball mill. Finally, this fine powder is blended with gypsum which makes the portland cement.

Cement Plant equipments

cement plant equipmentIn the cement manufacturing plant, not only the crushing machinery, but also grinding machine is used as cement producing equipment.

Stone Crusher: Limestone crusher Limestone is the main raw materials for cement production line, so we need the limestone crusher to crush limestone to small particle sizes to make cement.

Raw mill: it is widely used in cement plant used to crush limestone particles and additive materials for cement manufacturing.

Coal crusher and coal mill: They are used for crushing and grinding coal into powder in cement production line.

Gypsum crusher and mill: In cement plant, these machines are used for crushing and grinding gypsum into powder for cement manufacturing.

Cement mill: Ball Mill: Ball mill is the most widely used cement mill in cement plant, and is used to grind cement clinker into powder to make cement.

SBM is a famous cement plant equipment manufacturer in China, and offer types of cement crushers, cement mills and other cement machine for cement production line. SBM design cement plant according to layout diagram and process flow chart for cement industry in Kuwait, Pakistan, Ghana, USA, Russia, Brazil, Korea, India, UAE, Bangladesh.
