The rocks remain in between the jaws until they are small enough to be set free through this opening for further size reduction by feeding to the secondary crusher. Figure 13.9 . Schematic diagram showing principle of jaw crusher showing the path of lumpy feed ore to fragmented product crushed under high pressure of fixed and moving jaws.
· Rock enters the jaw crusher from the top of the machine and gets compressed between two surfaces — the fixed and moveable jaw. The rock will continue to be crushed until it is small enough to fall through the opening. Ensuring that the size of raw material is appropriately matched to the jaw opening, can alleviate blockage incidents.
Advantages of Jaw Crusher. Wide Application: It can crush many kinds of stones, and the common pebbles and limestone can be primary crushed by the jaw crushers;; Small Size, Small Floor Area: Unlike other crusher equipments, the jaw crusher is also convenient for installation due to its small size, and the infrastructure site used is also small, which can save a lot of site costs.
