This ball mill is mainly used for grinding raw materials and final products in cement plant. It can be replaced by vertical raw mill . It is also suitable for grinding various ores and other materials in the metallurgy, mine, chemical, construction and other industries.
2 Cement raw material has been almost exclusively ground in roller mills (vertical air-swept grinding mills) since the sec-ond half of the 20th century. Loesche was and is the pio-neer of this technology. Hundreds of Loesche mills
Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate ...
- 1 - Item Vertical roller mill for raw materials Application p rocess Raw material process Background Grinding raw materials needs lots of energy. Tube mills had been used for grinding, but the energy efficiency level was lower.
2020/04/04· Ball mills for cement raw material and coal equipped with a drying compartment adequately air swept with hot gas (2.5-3.5M/sec above the ball charge), can handle moisture about 8%. Fully air- swept mills (5-6M/sec) can dry up
Cement grinding unit cement grinding unit is also called the cement mill, raw material grinding, grinding materials, clinker grinding it is widely used in manufacturing industries such as cement, silicate products, new building
The cement raw materials is formed with calcareous materials, clayey materials and slight corrective material in appropriate proportion, and grinded into certain fineness. The raw material production of cement plant can be classified into four steps: crushing, grinding, mixing and homogenizing .
History Early hydraulic cements, such as those of James Parker, James Frost and Joseph Aspdin were relatively soft and readily ground by the primitive technology of the day, using flat millstones.The emergence of Portland cement in the 1840s made grinding considerably more difficult, because the clinker produced by the kiln is often as hard as the millstone material.
