Types of Crushers
· Crushers may be divided into three general classes, with respect to the manner in which they do their work: Pressure Crushers: This category embraces the several types of gyratory crushers and jaw crushers, as well as the double crushing rolls, with either smooth or corrugated shells. Impact Crushers: This division is represented chiefly by the various styles of hammermill; also by the cage ...

Mine Waste Transfer and Disposal Methods
The separation of minerals from gangue is called mineral processing. Oftentimes, inefficient processing methods can produce gangue that still holds an ample amount of valuable minerals. As values of minerals increase, it can even be profitable to reprocess gangue to extract additional minerals that may have been missed during the first processing.
