Crushing Machines Crushing Machines may be divided into: Crushers, Rolls, and Pulverizers. Ore as it comes from the mine is usually in larger lumps which require breaking up preparatory to the subsequent treatment it may receive. For this purpose mechanical means must be employed, and the following pages are intended as a rational treatment of the most approved methods, in ore crushing at the present day. If the material to be treated is coarse it is first put through a common jaw breaker, shown in Fig 1. PI. I In case the product is to be treated in rolls a jaw crusher is preferred to the breaker on account of giving a more uniform sized product, and therefore better prepared for the rolls. For all other crushing the breaker is preferred because of its greater 2.
