High-Efficiency 4PG Series Toothed Roller Crusher for Coal Crushing - Leading China Suppliers and Factory
Technical features
High efficiency, safety, energy conservation, environmental protection and large crushing ratio.
There is no requirement for the moisture content of the crushed materials, and they are neither sticky nor clogging.
The unique design that integrates the uniform distribution device and the fine powder screening device completely eliminates the phenomenon of overgrinding.
The coarse crushing and fine crushing are closely combined in the design, so there is no need to install a dust suction device at the inlet.
Low noise, low vibration, less dust and low power consumption.
The particle size of the discharged material is adjustable.
It occupies a small area and is easy to maintain.
The adoption of a hydraulic automatic yielding device and a debris removal device can effectively prevent the damage of non-ferromagnetic alloy blocks and hard stones to the toothed roller, as well as the harm of wooden blocks and flexible objects to the normal operation of the toothed roller.

Frequently Asked Questions (FAQ)
What materials can this series of roller crushers process?
This series is ideal for primary and secondary crushing of various medium hardness materials, including limestone, slag, coal, scoria, and fire-proof materials across metallurgy, cement, and chemistry industries.
Does material moisture content affect the crushing performance?
No, there is no moisture content requirement for the materials to be crushed. The design ensures the system remains non-sticky and free from clogging during operation.
How does the design prevent overgrinding?
Overgrinding is eliminated through a unique design that integrates a uniform distribution device with a fine powder screening device.
Is the discharge particle size adjustable?
Yes, the particle size of the discharged material is fully adjustable. Depending on the model, the discharging size ranges from 0.2 mm up to 10 mm.
How does the machine protect itself from hard foreign objects?
The machine features a hydraulic automatic yielding device and a debris removal device. These protect the toothed roller from damage caused by non-ferromagnetic alloy blocks, hard stones, wooden blocks, and flexible objects.
What driving and protection modes are available?
The crusher supports spring or hydraulic protection modes and can be configured with either a triangular belt drive or a coupling drive system.
