PFQ Series 200~300t/h Impact Crusher Machine

1.Description

Impact Crusher is a newly developed series impact crusher with high efficiency. It has smart structure and can be applied to primary crushing, secondary and fine crushing of a variety of materials with compression strength less than 250Mpa. Impact crusher can be widely used for mainly used in sand and stone yard, mixing station, construction waste crushing and other industries. Applicable materials: limestone, dolomite, construction garbage crushing, granite, basalt, river pebbles, etc

PFQ Series Impact Crusher has specially designed crushing chambers with three-section. It improves the production capacity, increases the feed size of material and makes the product shape adjustable,

2.Features

1. Specially designed three crushing chambers, which improves the production capacity of impact crusher, makes the feed size bigger and the product shape better.

2. The optimally designed rotor provides powerful rotational inertia and strong impact force of hammer head, which improves the productivity and increases the crushing ratio.

3. Specially designed anti-wear alloy C shape hammer keeps the shape of impact face in product life cycle. It ensures that the product shape and particle size distribution is very stable.

4. Standard modular designed liner and tooth impact plate of impact crusher have common-ability and interchangeability, which improve the utilization ratio and prolong the service life of impact crusher.

5. Special hammer fitting structure improves hammers' stability and convenient dismounting, it also greatly improve the work efficiency.

6. The discharging opening size of the machine can be adjusted according to the requirement of product size and particle size distribution.

7. The standard hydraulic lifting device will be provided with the machine. It is optional to supply special lifting tools for replacing hammers, which is flexible and can be easily maintained.

3.Working Principle

Electrical motor drives through V-belts and makes the rotor run at high speed. Materials will be fed into the crushing chamber from feed inlet, and be struck by the plate hammer which rotates at high speed. The materials are thrown up to the dentate reaction plate on the top of the crushing chamber and then falls down, the thrown-up and falling-down materials are crushed by striking with each other. The big incompletely crushed materials will form big stress and bending force at the interaction of hammer and thick impact plate in P crushing chamber, even the hard crushed materials will be broken and enter into the following S and T crushing chamber. The materials in these two crushing chambers can be medium and fine crushed by striking, impacting, bending and extruding, then discharged out of the machine.
