The three general forms of the jaw crusher are: Blake. Dodge and Universal. These are distinguished by the manner in which the movable jaw is moved in relation to the stationary jaw. In the Blake-type crusher, which is the most common type of jaw crusher, the movable jaw is pivoted at the top so that it has a fixed receiving area Blake Crushers. Blake Crushers are Jaw Crushers with a movable jaw pivoted at the top, giving greatest movement to the smallest lumps. The throw of Blake jaw crushers is determined by the hardness of the ore as well as the size of the machine.
