SBM Cement Plant For Sale

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 packing

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

Stone Crusher: Limestone crusherLimestone is the main raw materials for making cement, so we need the limestone crusher to crush limestone to small particle sizes to make cement.
Raw mill: it is used to crush limestone particles and additive materials

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

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

Cement mill: Ball Mill: They are used to grind cement clinker into powder to make cement.

LM Series Vertical Grinding Mill

Vertical Roller Mill IntroductionVertical Roller Mill is a new kind of large scale power mill which is designed specially to solve the problems of low capacity and high consumption of industry mills. With a decade of years’ research of mills, Vertical Roller Mill is designed and manufactured based on our advanced design idea, and in combination with the European technology and the market demand. It adopts reliable structure and reasonable process flow, integrated with drying ,milling, classifier , elevator. Especially ,it can fully meets the requirement of clients in the high production of powder and its main technical and economy indicator reaches the international level.

Application:Specialized for the high production of superfine pyrophyllite powder making in glass fiber industry Specialized for the high production of gangue powder making in coal industrySpecialized for the high production of various of chemical raw material powder making in the chemical industry.It is a necessary equipment for the high production of mineral powder in the non-mental mine industry and large scale powder making in many other industries.

Working principles of the Vertical Mill CLM:

The motor dives the grinding table to turn through the speed reducer. At the same time, hot air comes into the roller mill from the air inlet. The materials fall down the centre of grinding table from the feeder. Because of the centrifugal force, the materials move to the edge of grinding table from the centre .The materials are crushed by the grinding roller when by pass of the groove on the grinding table. The crusher materials continue to move to the edge of the grinding table until taken away by the airstream. Then the bigger materials fall down the grinding table and the process of crushing continues. When the materials in the airstream pass the separator on the top of the mill, the materials fall down the grinding table from the taper filler under the force of guide leaf blade. The fine powder comes out with the airstream, and is gathered by the dust catcher of the system. The powder gathered is the final product of roller mill. In the process of the contact of airstream , the materials are dried to meet the clients’ need at the proper moisture.Through the adjustment of the angle between the separator and the leaf of wind's direction (not suitable to the small type of vertical mill), and also the speed of the separator rotor, it can reach the proper fineness of the materials.
