The 4PG series of four tooth-roller crusher is a new model of crushing machine which is developed for the fluidized bed boiler in power plant and coal handling system in washery. It can be used in industries such as metallurgy, chemical, mine and building material to crusher non-metal material with its compressive strength between 50- 110MPa, especially for crushing fine coal, brown coal and all kinds of raw coal containing coal gauge less than 70%.
Advantages and features
- High efficiency, safety, energy-saving, environmental-protecting, high reduction ratio;
- The special model of machine for power plant can ensure it is 90% that discharging size is less than 10mm.
- The frame adopts box-welding fast dismount structure, which could reduce the cost of maintaining.
- The toothed plate is alloy steel covered with wearable layer by surfacing which could ensure the longer service life of 6000 hours. Toothed plates are inset one by one so that plates are easily changed.
- The machine is equipped with hydraulic protective device to protect the machine. It is safe and reliable.
- Less noises, less vibration, less dust, adjustable discharging size, small location and easier maintenance.
- It adopts hydraulic auto-withdrawing device and dust cleaning device which can prevent damages on tooth roller from non-iron alloy cake objects, hard rock including also wood and soft objects.

New technology double teeth roller crusher with best service composed by rollers which rotate toward each other , material directly falls into for the size in accordance with two teeth roll gap, exceed the gap's material are crushed by rollers of splitting, breaking, and striking then falls to meet the granularity's requirement. Relative roller differential operation can clear up the slot residual materials, all of this avoidance the material's repeated crushing, without gluing and plugging
Teeth roller coal crusher machine with 100% non gluing and plugging adopts double protection of electrical and mechanical, electrical control cabinet is equipped with PLC programmable controller with chain safeguard function, which can realize local control and central control room manual / automatic control, so which is the ideal crusher for heating and power supply.
