cement grinding machine brief introduction:
The ball mill is one kind of new high efficient grinding machine. This mill is mainly used for coarse powder and small size of sand producing. The ball mill is widely used in metallurgy, mining, chemical, cement, construction, industrial and mining industries etc.
cement grinding machine features:
Milling efficiency
Mechanically simple design
Competitive capital cost
Use of low cost, ceramic, natural silica sand or pebble media
No steel contamination of product
Capacity to operate continuously at full load power draw
Low rotational impeller speed with shallow charge depth providing reduced abrasion of impeller and body liner coverings
cement grinding machine benefits:
High production capacity and high crushing ratio.
Low power consumption, uniform particle size.
Simple structure, easy to operate.
Low investment cost, easy management.
To reduce the resistance, no accumulation of materials the use of curved duct and tangential air flow into the sliding reduce the resistance. The export orientation to the dispersion of the material inside is not easy to jam. Compact the design of tapered gear driving the spindle overall transmission and integration structure makes the machine more compact structure, which make installation and adjustment faster and more convenient.
cement grinding machine application:
The ball mill is key equipment in grinding industry, especially in mineral ore dressing plants. It is widely used for the cement, the silicate product, new type building material, fire-proof material, chemical fertilizer, black and non-ferrous metal, glass, ceramics and etc.
cement grinding machine working principles:
Open system: In the grinding chamber internal grinding material with certain water content, the grinding heat generated in grinding chamber gas vaporizing expansion changes the gas flow rate, and the various machine pipe joint seal is not strict, let the outside gas is inhaled, the circulating air volume increase, therefore to achieve balance through adjustment of air exhaust fan and host the pipe, and the excess gas into the bag filter, the residual gas into the powder collected, the residual gas is discharged after purification.

Project Case
New dry cement process in cement plant
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
