3 Terms and Definitions
The following terms and definitions apply to this document.
3.1
Grinding Work Index grindingworkindex (bal)
An indicator to evaluate the power ore grindability degree of difficulty.
3.2
Circulating load circulatingload
It refers to the mass percentage of the mill to return the amount of the amount of product, namely.
Ci = AiQi ×
Where.
Ci --- cyclic load i-th cycle,%;
Ai --- i-th loop back mill material mass in grams (g);
Qi --- i-th round grinding mineral mass in grams (g).
4 principle of the method
Through a number of closed-circuit grinding intermittent screening simulated continuous closed-circuit grinding process, measured at the time of grinding mill to balance the newly generated per revolution
The amount of product, and thus calculate the ore grinding work index.
5. Apparatus
5.1 mill work index
Effective volume φ305mm × 305mm, speed 70r/min, ball bearings for the ball with the ball, the total mass of 20.125kg, ball level
