Estimation of the Specific Energy Requirement for Size Reduction .
08/11/2016 · where (y_{p}) is the 80% passing size of the mill product, (y_{f}) is the 80% passing size of the mill feed, C is a millmaterial constant, and α is the exponent of particle size (its significance discussed in detail later). It has been shown [] that the value of the exponent α varies strongly with the material type, generally in the range of 0–2.

MODULE #5: FUNCTIONAL PERFOMANCE OF BALL MILLING
grind size. For any process, including ball mill circuits, we can say that output equals input multiplied by efficiency*. Output = Input x Efficiency In a ball mill circuit, the "output" can be defined as the production rate of fines of the circuit. As for any output, ball mill circuit output is a function of both its inputs and efficiencies.

The effect of planetary milling conditions on tungstencarbide .
10/01/2020 · For effective size reduction planetary ball milling is been used here. In planetary ball milling high energy transfer takes place by the action of two centrifugal force acting on the milling balls in opposite direction at the same time. This causes the transfer of energy from impact and shear of balls and powder.
