Mill Liner Form With A Large Ball In Grinding Efficiency

One of the hot mineral processing equipment industry has large-scale efficient energy saving, environmental protection and other equipment at home and abroad, using the conventional ball mill according to the principle of scaling the previous design of the ball mill greatly affected by the large ball mill grinding mill, many defects exist within efficiency.

Ball mill grinding effect is caused by the movement of the grinding medium, grinding centrifugal efficiency upset under the trajectory Paola of the three common movement patterns medium to the large ball mill liners media direct grinding steel power consumption. To obtain a good trajectory, Qiming Machinery  Technicians choose different shape liners, the influence of the shape of the liner on the media law of motion, the impact useful power and energy distribution, design, grinding liners with different shapes.

Different shapes of different liners polishing efficiency at the same transfer rate:

The difference can change the shape of the liner and the way of contacting the descending point into the medium, which greatly affects the barrel elevation power system, the medium trajectory. Experimental comparison, through a large ball mill liners at the same transmission speed, different shapes of media, different liners on the descent point and landing point of the media, a great influence on the medium trajectory. At the ideal transmission speed, the mill liner rectangle is the lamination medium serious of the medium, but the inner and outer layer material impact crusher of the outermost layer occurs down the role, but the outermost layer of the medium is no more lining, the Paola sports media trapezoidal plate plant, descending Media layer in height is relatively large compared to the ideal trajectory, and the shape of the mill liner of the corrugation, falling from the most state media, but a large number of medium-height Paola inner layer, very small impact on the material crushing effect is limited.

Lining different shapes applying different baud rates:

Qiming Machinery machine manufactured through floorspace ore processing equipment's media operation state and combined test, so visited the large rectangular mill useful power, effectively affect the media lining media area up to maximum, found that the transmission rate is less than 60%, the transmission rate is less than 60% Less, rectangular liners should be used. Although the maximum useful power of the trapezoidal liner rolling mill at a rate of 80%, but some media is directly hit the ground opposite the exposed liner, therefore, if this ratio transfers more than 75%, choose a corrugated liner; A proportion of 60%-75% should be used for trapezoidal liners that transfer.
