Natasha Chandri Egieara. Mineral Processing. 1306436741. Circulating Load Ratio. Circulating load ratio (CLR) is defined as the ratio of the amount of solids going through the ball mill divided by the amount of solids going through the circuit. Therefore, the value calculated should determine the number of passes through the mill needed to generate the total amount of new

18.10.2020If circulating load in the second ball mill is kept constant, any variation in the fresh feed will ultimately be reflected in the product particle size of Cyclone 2. Water addition to Cyclone 1 feed sump therefore not only controls the Cyclone 1 product particle size, but ultimately also Cyclone 2 product particle size.

Conical Ball Mills differ in mill body construction, which is composed of two cones and a short cylindrical part located between them (Fig. 2.12).Such a ball mill body is expedient because efficiency is appreciably increased. Peripheral velocity along the conical drum scales down in the direction from the cylindrical part to the discharge outlet; the helix angle of balls is decreased

The starting point for ball mill media and solids charging generally starts as follows: 50% media charge. Assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space) 50% x 26% = 13% free space. Add to this another 10%-15% above the ball charge for total of 23%
