parameters ball milling
In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rob mill & ball mills, the ore in order to liberate the minerals. In the chemical and process industries, grinding is an important step in preparing raw materials for subsequent treatment.
Milling of slurries presents less technical challenges than dust milling, but if dewatering is necessary it may be impractical. A simple ball mill can be constructed by almost anyone, but obtaining the hard pebbles with the correct range of sizes for inside the mill can be challenge (they are expensive).
Ball Mill Design Parameters. Size rated as diameter x length. Feed System. One hopper feed; Diameter 40 – 100 cm at 30° to 60° Top of feed hopper at least 1.5 meter above the center line of the mill.
The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media.
The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
