2017-1-16 In the Chase separator, as shown in Figs. 1 and 2, there are three of these magnetic rolls, A, B, and C, Fig. 1. The function of the first roll is to separate a wholly non-magnetic grade of tails from the remainder of the material treated. As the crude material is fed upon a belt, which approaches the wheel horizontally, the necessary ...
