The most suitable number of work rotations in production is: n = (0.76 - 0.88) × critical number n. Transfer / minute. The actual production proves that when the filling rate of the grinding medium is 54%, the turning rate is set to 88% of the critical number of revolutions and the grinding productivity is higher than 76%; for the fine grinding (when the ore size is less than 3 mm, the grinding When the mineral product is below 0.1 mm, if the conversion rate is set to 88% of the critical number of revolutions, it is obviously high, which affects the quality and should be slightly lower. 78. Under what conditions can high-frequency grinding be used? In the current production, the grinding machine's rotation rate is less than 76% of the critical number of revolutions, called low-speed grinding; when the revolution rate is higher than the critical number of revolutions of 88%, it is called high-speed grinding; the rotation rate is greater than 100 % is called supercritical revolution grinding. The production practice proves that the ball mill with smooth lining has a medium filling rate of 30-40%, and at the same time appropriately reduces the grinding concentration, so that the ball mill rotation rate is increased to 100-104% of the critical number of revolutions. Under normal circumstances, the processing capacity can increase by 10-30%. Only when some of the above conditions are met can the high-rotation grinding be used, but it will also bring about the harm of reducing the fineness of grinding, so it is impossible to unilaterally pursue a high-speed grinding machine.

What kind of work turnover is good for production?
The working revolution of the grinding machine refers to the actual number of revolutions of the grinding machine in good working condition.
