G – the grinding balls mass in ball mill, t j – the mill filling degree with grinding balls, V – the mill volume, m3 g ш – the grinding balls bulk weight, t m3. The correct determination of the grinding balls bulk weight in mill allows accurately determination the.
Jul 10, 2019 In general, the loading volume of the ball in the ball mill is lower than the horizontal line in the cylinder, and it is better to control the ball quantity at about 40 ≤ 50 . At this time, the productivity of the ball quantity is higher, and the ball loading quantity can be controlled at about 35 for the smaller ball mill, which can.
When the speed of the ball mill is fixed and the ball loading is 30 , the ball movement is mainly sliding, but it has already begun to incline.When the amount of ball loading exceeds 40 , the ball movement is mainly in the form of inclined flow.When the ball loading reaches 50 of the cylinder total capacity , the surface of the ball group is.
Sep 15, 2008 Ball mill load is the most important parameter optimized in the Ball Mill Pulverizing System (BMPS) in Thermal Power Plant. The accurate measurement of ball mill load is imperative and difficult. The approach based on self-adaptive feature extraction algorithm for noise signal and LS-SVM model is proposed to achieve this purpose.
