ROLL CRUSHERS
WHAT IS A ROLL CRUSHER?
Roll Crushers are unique machines which crush material by means of compression between two parallel cylinders that rotate in opposite directions. They can handle wet and sticky material while generating minimum amounts of fines and producing great cubical product. This makes them very useful in mining applications.
EFFECTIVE CRUSHING
The amount and size of material that the roller crusher can handle varies depending on the gap distance between the rollers. According to the desired material size, GRAU Roll Crushers can be designed to have large feed openings, enabling an effective capacity increase.
