In this study the comminution methods of graphite bearing ore were compared by using five different crushing methods, namely a jaw crusher, a roll crusher, uniaxial compression tests, and a new type of continuously compressing crushers. These new continuously compressing crushers were available in laboratory and pilot scales.
A crusher, also known as a stone crusher, is a machine that uses mechanical action to break large rocks, ores, or other raw materials into gravel or rock powder. ... Impact crushing: This method uses high-speed moving parts to strike the material, breaking it under the force of impact. This technique is employed in impact crushers, hammer ...
