Jaw Crusher Components Parts

Although the jaws do the work, the real heart of the jaw crusher and its components are the toggle plates, the pitman, and the ply wheel. These are the parts and components that generate the crushing action and provide the energy needed to break the ore. Let’s follow the chain of events within a crushing cycle to see how they all go together. The first component of the crusher is the drive ...
