There are many types of crushing equipment, different styles and models, although all are called crushers, but each one is different, different products, performance and advantages are completely different, and the products that are suitable for crushing are also different. Counterattack crusher and hammer crusher are commonly used in the crushing equipment, the two work similar principles, are crushed materials by impact, but the structure and work process are different.


First, the broken way is different:

(1) The hammer and rotor of the impact crusher are rigidly connected, and the inertia of the whole rotor is used to impact the material, so that the material is not only broken but also obtains greater speed and kinetic energy.

(2) Hammer crusher Because the hammerhead and rotor county are articulated, it only uses a single hammer to attack the material and crack the material. The speed and kinetic energy of the material are small.

Second, the space in the crushing chamber is different:

(1) The crushing chamber of the impact crusher is relatively large, so that the material has a certain space for movement, and the impact is fully utilized. Under the action of the hammer, the material impacts the counterattack board.

(2) The crusher cavity of the hammer crusher is small and the material is mainly broken by a hammer.

Third, different working principles;

(1) The crushing process of the hammer crusher is roughly when the material enters the crusher and is broken by the impact of a high-speed rotary hammer. The broken material obtains kinetic energy from the hammerhead and rushes into the frame from the high speed. The baffles and screen bars, at the same time, the materials collide with each other and are broken up several times. Material smaller than the gap between the screen bars is discharged from the gap. Individual larger materials are again impacted by the hammer head on the screen bars. , crushing and crushing, the material is extruded from the gap by the hammer to obtain the desired particle size of the product.

(2) When the impact crusher is working, driven by the motor, the rotor rotates at a high speed. When the material enters the impact zone of the plate hammer, it collides with the plate hammer on the rotor, and then it is thrown toward the counterattack device and broken again. From the backing lining board, it is bounced back to the area where the hammer hits, and the process is repeated. The process is repeated from the largest to the smallest. The first, second and third counterattack chambers are repeatedly broken until the material is broken to the required grain size. I discharge.

Fourth, the advantages of impact crusher and hammer crusher:

1. Counterattack crusher Advantages: Large crushing ratio, good granularity of finished product; easy replacement of spare parts and corresponding reduction in maintenance costs; applicable to both soft materials and materials with very high hardness; convenient and flexible adjustment of the material size, And the discharge particle size adjustment range is wide.

2. Advantages of hammer crusher: save investment cost, high production capacity; simple structure, low power consumption, convenient management; large crushing ratio, high finished product rate, excellent performance; can be used as a broken one, can be counter-attack broken only two Broken; easy maintenance, flexible adjustment, durable, good particle shape.

The above is the difference between the impact crusher and hammer crusher, the advantages, each has its own good performance, choose the most suitable product for you, is the best choice, hope that we provide you with these content can bring you good The reference for you to make a better choice, Shandong crusher manufacturers Yuxiang machinery sincerely for the sake of customers, to show customers a good service!
