Ball grinding mills market are mainly concentrated in the cement industry. The grinding operation of modern cement industry, included thecement grinding plant,raw material grinding, slag grinding; to produce 1 ton of cement would need nearly 3 tons of materials; power consumption for grinding operations substantially more than two thirds of the cement integrated power consumption,
The ball grinding mill operation of the cement industry in the last 20 to 30 years experienced significant technological progress. In terms of raw material grinding, vertical roller mills have been almost completely replaced the ball grinding mill, enjoy a wide range of absolute dominance; in terms of cement and slag grinding, a simple ball mill system has been less used, vertical roller mills are a lot to promote the use of being; in recent years in the developed world market share of more than 70%, to coexist with the (remaining 20% more) is a roller press grinding or semi-final finish grinding system; in coal preparation, vertical roller mills adoption rate are quite high. If we say, 10 years ago, the cement industries are a variety of grinding equipment flowers in full bloom, flourish era, such as roller presses, roller mills, vertical roller mill, etc., are intended to reform fundamentally the ball mills grinding efficiency is too low malpractice and developed a new grinding equipment, industrial practice and then after nearly 10 years of technological competition test, vertical roller mill has finally come to the fore, almost forming a domination.
Throughout the cement industry raw material grinding technology and equipment development process, vertical roller mill after 20 years of practice and improvement, has been able to replace the dominance of milling, and in various other newly developed grinding equipment competition ultimately invincible, which is a main reason that it benefited from NSP cement firing technique to lay the absolute advantage of the position, or is it just well adapted to dry kiln development needs, complemented by ground and common development, complement each other. Its main advantages are:
1. Restricted use of local material bed crushing principle, to improve the grinding efficiency.
2. Strong ventilation drying capacity.
3. Saving electrical energy consumption broken.
4. Small operation running noise.
5. Focus broken, grinding, drying, separator and pneumatic conveying of five operations in one unit.
6. Short material residence time in the mill.
7. Strong performance of a variety of raw materials adaptability.
8. Metal wear less.
9. System less air leakage.
10. Cement equipment to adapt to large-scale deals.
