New type of jaw crusher featured with following characteristics:
1. Large compound pendulum jaw crusher. The previous type of large size jaw crusher that used to crusher hardness material is usually adopts single pendulum type. Only medium and small size jaw crusher adopts compound pendulum type. Since the show up of heavy load rolling bearing and the improvement of material and design, large size jaw crusher can also adopts compound pendulum mode to make full use of this simple structure design, the machine weight could be reduced (20%-30%) and the output could be increased 30%.
2. Welding technology has been widely used. The frame body is made of welding techniques. For smaller machine applied overall welding technology. For bigger one, the machine is assembled by 4 to 6 large welding structure.
3. The wide application of rolling bearing: Some bearing manufacturers specially design a kind of bearing that can withstand high impact load as well as the heavy loading bearing. The installation method and the sealing method should be strictly ruled and required.
4. Widely adopt hydraulic and lubricant recycling system, for instance, the hydraulic-controlled safety device as well as the discharging device and the lubricant recycling system for driving units.
5. The toothed plate is made of high manganese steel with manganese content about 12-14%. For harder material, usually uses high manganese steel with 17%-19% and 1%- 2% Chromium or Picolinate in additional to make toothed plate.
