Compare Fast and Slow Crush Products

It is important to note that the products of the two classes of crusher (low-speed and high-speed) cannot be compared directly upon the basis of their respective open-side and close-side settings. Nor, indeed, can the products of nay two types in the high-speed class be compared upon this basis, unless it is known that their speeds, throws, and general shape of crushing chamber are similar.

* In the case of the high speed crusher, there will naturally be occasional pieces get through that are a little larger than they are unimportante. Fine reduction crusher installed in an Eastern crushing plant.   

As between crushers of the high-and low-speed types, the low-speed machine at nay given open-side setting will the high-speed machine at the same close-side setting. For example, in one installation where the machine are working on  the same material, a standard type gyratory, fitted with non-choking concaves, consistently de livers a product 85 percent of which passes a square-opening test sieve equivalent to its open-side setting. A high-speed, gyratory, fine-reduction crusher in the same plant jut as consistently produces material 70 percent of which passes a square opening test sieve, equivalent to its close-side setting. In both cases al dimension not exceeding these respective open – and close-side settings. This is a typical case which gives a pretty fair average comparison of products from machines rated on these two different bases.
