Module 5 Functional Perfomance Of Ball

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.

Introduction To Machining Milling Machine

Work on a milling machine is most often held in a vise clamped onto the bed. To make features aligned with the edges of the stock, its necessary to align the vise with the feed axes of the mill. To do this, mount the vise on the bed and secure it with T-bolts, but only lightly so as to permit adjustment of the orientation of the vise.
