Feed in size	600-1200 MM
Capacity	100 – 700 TPH
Application	Widely used in metallurgy, construction road, railway and commercial concrete industry sand and gravel aggregates.
Scope of Application	It is suitable for crushing soft and medium hard ores for primary or fine crushing operations, such as granite, diabase, basalt, pebble, limestone, dolomite, metallic ores and non-metallic ores, etc.
Machine Introduction	PFT Big Mouth Impact Crusher, it is a new type impact crusher developed on the base of foreign technology and the latest processing technology, it has the following advantages compared with general impact crusher. 1. Adopting hydraulic top device and maintenance lifting design, which reduce halt and maintenance time and cost of maintenance. 2. Adopting full-automatic hydraulic adjusting between rotor and impact plate enable flexibly discharging size adjustment.  3. Adopting heavy-duty rotor welded from high quality steel plate, enable its owns greater rotatory inertia. That means, with the same rotate speed, it has stronger crushing force, high efficiency. 4. Adopting bigger specification bearing with stronger bearing capacity. 5. Bearing pedestal adopts overall forging steel, which can perfectly fit the crusher frame and increase the radial force of bearing pedestal. Excellent waterproof and dustproof effect can protect the bearing.
Working Principle	PFT Big Mouth Impact Crusher breaks materials with impact force. When working, driven by a motor, the rotor rotates at a high speed. When materials enter the working area of hammer, they are crushed under the high-speed shock. Then broken materials are thrown onto the lining plate for another crushing. Finally, qualified materials are discharged from the opening. Adjusting the gap between the impact rack and rotor rack can change the granularity and shape of finished products. 1. Adopting full-automatic hydraulic adjusting between rotor and impact plate enable flexibly discharging size adjustment. 2. Hydraulic top device and maintenance lifting design can achieve the change of board hammer and other wearing parts in a short time. 3. Heavy rotor design is more durable bigger crushing force. Strict quality control high stability longer service life. 4. Adopting wedge to fix the plate hammer ensure roller to be firm under high-speed rotation. Reliable work convenient changing.

 
 
Performance   
 
Integrated Application Of Latest Scientific Research Achievements
Based on the analysis of technical details and operating conditions of domestic and foreign impact crushers, Impact Crushers integrated many latest scientific research achievements, for example, those concerning crushing chamber, rotor and adjusting device. Thus, the crushing operation and maintenance reach higher level.

Higher Crushing Efficiency – Heavy-duty Rotor with Strong Rotary Inertia and High Precision
Impact Crusher adopts the heavy-duty rotor with strong rotary inertia and high precision. Meanwhile, it is equipped with high-quality bearings, ensuring the precision and big holding capability of the rotor. So, further, materials can be fully crushed. The crushing ratio is bigger.
 
Involute Crushing Chamber Ensuring Shape of Finished Products
The involute crushing chamber of Impact Crusher is efficient. Materials can be crushed several times inside the chamber. After crushing, finished products have good cubic shape which can better serve as high-quality aggregates.
