Impact crusher

Impact crusher is an efficient crusher for coarse, medium and fine crushing of medium hard and soft rock. Whether in quarries, mines or construction waste recycling, the impact crusher can efficiently crush stones, so that the particle shape, particle size distribution and cleanliness meet the strict standards of concrete and asphalt aggregate. Impact crushing equipment not only has first-class product quality, but also has high output.
Let’s look at the layout of the crusher in the production line:

Impact crusher in the production line

Impact crusher assembly: The impact crusher is mainly composed of frame, rotor, impact frame, main shaft wheel, lining plate, hydraulic regulating device, hydraulic starting device, etc.

Advantage Counterattack crusher

In view of the problems existing in the crushing efficiency and processing capacity of the previous generation of impact crusher, ci5x impact crusher optimizes the crushing cavity, rotor speed and power curve, improves the crushing efficiency and crushing ratio, further optimizes the shape of finished aggregate and makes the grading curve more reasonable.

The comprehensive treatment capacity of the equipment is more than 15% higher than that of the previous generation, and can meet the requirements of preparing aggregate for high-grade concrete.

1.High efficiency crushing chamber, higher crushing efficiency

2.Multifunctional hydraulic operating system, easy maintenance

3.High strength counter rack

4.Heavy rotor

 Specification of Impact crusher

Impact crusher PF

PFW impact crusher is a new type of high-performance hydraulic crusher developed by adopting international advanced impact crusher technology. It is very suitable for coarse, medium and fine crushing of various soft and medium hard minerals and rocks.

Advantage of Impact crusher PF
Integral cast steel structure bearing seat
Heavy rotor design
The two cavities can meet the crushing requirements of most coarse, medium and fine crushing operations.
Reliable wedge fixing method

Pf impact crusher

Pf impact crusher adopts traditional impact crushing technology. After years of design optimization, the performance is more excellent and the use is more reliable. It is the most common fine crushing equipment for medium hard and soft materials.

Through the optimized design of PF impact crushing chamber and rotor, the production capacity and finished product particle size are higher than those of traditional impact crushing. The counterattack frame and rotor are mechanically adjusted, which is simple and reliable.

Working Principle

Impact crusher crushes material by striking energy.when it works,the motor drives the rotor rotate at a high speed,on which the blow bar is installed .as soon as the material get into the affecting area of the blow bar,they will be stroke by the blow bar and be thrown to the impact devices around the rotor.the high speed forces the material to rebound from the impact liner to the area where the blow bar effects until they have been crushed to the required size.the clearance between the impact rack and the rotor can be adjusted to change the size and shape of the end product.

Impact Crusher Working Principle

How to choose a granite crusher?

According to the different products required, a crushing process can be divided into coarse crushing section, medium crushing section, fine crushing section and grinding section.
General materials can be divided into three major types of process engineering according to the required products: coarse crushing + medium crushing, coarse crushing + medium crushing + fine crushing or coarse crushing + medium crushing + fine crushing + shaping. Shaping is generally to make the obtained product better in grain shape.
Commonly used crushed products in the whole crushing process are as follows:
The jaw crusher is used in the first crushing process of the crushing line. It can crush large particles with a compressive strength of not more than 320MPa to a size of 100mm~300mm.
The impact crusher generally can process ores or rocks with a compressive strength of up to 350MPa under 500mm, and the crushed materials are cubic particles. The impact crusher is generally used in the second crushing process of the crushing line, and can also be used as the first crushing process for materials with a small input.
The cone crusher uses the principle of laminated crushing to form a protective layer of the material layer. It has the characteristics of reliable structure, high crushing efficiency, convenient adjustment, and economic use. The feed size is 13~369mm. Cone crushing is the same as impact crushing. It is often used in the second crushing process of the crushing line. It can also be used as the first crushing process for materials with small feed. However, the feed particle size of cone crusher is generally smaller than that of counter-attack crushing.
The sand making machine is suitable for crushing and shaping of soft, medium hard and extremely hard materials. It is generally used as the last process of the crushing sand production line, and the feed size is 35-60mm.
In addition to the main crushing equipment, some auxiliary equipment such as vibrating screens, feeders and conveyors are needed to complete the configuration and work of this production line.

impact Crusher VS jaw Crusher

Jaw crusher and impact  crusher is commonly used in crushing industry. Here I will introduce the difference between the hammer crusher and jaw crusher. Firstly, we know that both of them is used for the coarse crushing. In addtion, they also have many different points.

Different Working Principle.

Different designs mean that they work differently, have different working principle.Jaw crusher is arc dynamic extrusion type, the material is crushed in the crushing cavity composed of moving jaw and fixed jaw. The hammer crusher breaks the material by impact.

Different Applicable Materials.

Hammer crusher and jaw crusher is used to crush the different hardness materials. Jaw crusher can crusher all kinds of soft and hard materials with compressive strength between 300-350Mpa, such as quartzite, granite, diabase, pebble, iron ore, etc. While the hammer crushing machine only can crusher the ores with low hardness that compressive strength is generally lower than 200Mpa, such as limestone, coad gangue, bluestone, etc.
