Crusher
Crushers are used for the breaking down of input material into particles of less than 30 mm in size. They enable you to align overall efficiency requirements for your process, based on particle size. The low-speed crusher shaft makes sure the unit can deal with any foreign objects (such as metal) in the input material.
Cone Crushers (Parts of a Cone Crusher) Explained
Feed from a feed hopper is fed into a large opening at the top of the cone crusher. Feed then falls due to gravity and is crushed between the mantle and concaves; crushing takes place in the crushing chamber. As the feed moves towards the drive end of the cone crusher, its size decreases (due to the crushing action), and ever smaller pieces ...
