Ball mill - skills of choose and buy
1, to ensure that the mill production capacity
Chooses the grinding equipment, in guarantee under the condition of the grinding fineness required, to complete the production by the rules.
2, production capacity should be higher than the design of some
Design should consider the ore hardness and the change of the fineness, generally deep ore deposit hard or fine, should make chooses grinding machine can adapt to, at the same time to ensure smooth production early.
3, must do grinding test
There is no actual data as a basis, in the design must be grinding test requirements, especially the large mill, grinding machine selection is made the basis of the data obtained from the calculation and proportional amplifier.
4, large-scale equipment, due consideration
In the design of the enlarged equipment is the 21st century. Because of its large equipment, general equipment, light weight, covers an area of less, less production system, operators and less auxiliary system, the corresponding investment and production cost is low. But large equipment operation and management level of demand is high, operation efficiency, if slightly lower, will greatly reduce the production of concentrator.
5, with high rates of operation equipment
There are good and bad in the equipment of the same type of old and new. Sometimes rod mill, the mill operation rate lower, but under certain conditions still apply. In principle, should choose high rates of operation of the equipment, in order to reduce maintenance and parking time.
6 and understand the hardness of the mineral, grade, such as nature, try to choose energy-saving ball mill; 7, know mineral grinding fineness, requested minerals required fineness according to oneself, choose and aperture of closed plate points position; 8, according to the requirements of production, choose appropriate length and the diameter of ball mill is 9, select a new generation of modified type ball mill, best to correspond to your minerals of professional ball mill manufacturers to buy 10, large selection of ball mill tooth, small modulus gear, as well as the motor, reduction machine manufacturers, according to the price of ball mill, the requirement of lining board of the grinding material and the thickness of the steel plate.
