Considering many friends ask for advices on how to choose the high quality ball mill, experts of Shanghai Esong mine machinery give five principles should be adhered when choosing high quality ball mill. And the details of the advices are as the follows: First, the basic production capacity of ball mill. The selecting ball mill must complete the required yield under the circumstances of ensuring the required fineness. Second, the expansion capacity of the ball mill should be strong than when it was designed. Considering the hardness and fineness of the ore material changes, such as the hardness and the fineness of general deposit deep ore will become harder and finer, the grinding mill should be with wider adaptability, which is in order to ensure the smooth operating of the ball mill. Third, before you make a decision you should through grinding experiment of the ball mill, which is necessary when there is no actual data as a basis in the design, especially for large ore dressing plant, it is more necessary and you should be more cautious. Fourth, the large-scale consideration of the grinding equipments is also necessary because it is the the recent design trend. The large-scale equipment means the equipments with a slight general equipment weight, cover a less area and with less production system, operators and auxiliary system, so that the corresponding investment and production cost will decrease. However, large equipment has a higher requirements of the operation and management. If the working efficiency slightly decreases, which will significantly reduce the yield of the ball mill. Fifth, the efficiency of the ball mill should be as high as possible, the quality of which has the difference of old and new as with the same type of equipment. The operating rate of Rod mill and ball mill sometimes is low, which also is not suitable under specific conditions. In principle choose high operation rate equipment can reduce the maintenance and parking time. When you choose high quality ball mill equipment, the above five principles should be adhered. In general, small and medium dressing plant adopt conventional rod grinding or milling equipment; but for large ore dressing plant, it should consider using self grinding, semi self grinding, which is superior to conventional equipment.
