The hammer mill is the best known and by far the most widely used crushing device employing the impact principle of breaking and grinding stone. Thus far we have described machines which do a portion of their work by impact, but the only machine described in which this action plays an important role was the sledging roll type and …Web

The gradation is controlled by adjusting the spacing between the mantle and the concave at their closest point. This is accomplished by raising and lowering the top or bowl of the crusher. A finer setting will create a finer product but at a lower throughput. Speed can also help to determine the final output gradation.Web
