m. Note thatin order for no correction factor for ball mill product fineness to applythe ball mill circuit P80 should be no less than approximately 70 m Bond, 1962. This Bond Efficiency determination should not be applied to cir-cuits with a P80 finer than approximately 70 m without making qualifications. 3.
In the range of 45-65 solids, typically used in ball mill circuits, cyclone classification efficiency is commonly lower than 50. This has an adverse effect on ball mill circuit capacity as shown by work conducted by Hukki and his co-authors 1965, 1968, 1973, 1979.
involve grinding. With Lloyds ball milling book having sold over 2000 copies, there are probably over 1000 home built ball mills operating in just America alone. This article borrows from Lloyds research, which was obtained from the commercial ball milling industry, and explains some of the key design criteria for making your own ball mill.
Dec 02, 2016 circuit is shown in Figure1. It is commonly referred to as a SABC circuit, for Semi-Autogenous Ball mill Crusher SABC. This circuit shows a semi-autogenous grinding SAGball mill circuit where both grinding mills are in closed circuit, with the SAG mill closed with a crusher to control the amount of critical size material in the circuit.
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. There are two inputs to a ball mill circuit the ore fed to the circuit and the power delivered by the grinding mill.
in a SAG and Ball mill circuit where there is no scope for storage capacity between milling stages and throughput is normally limited by a bottleneck at one stage or the other. In this case any ore with a high BWi value will have reduced . throughput due to the ball mill despite the capability of the SAG mill
