The Difference Between Counterattack Crusher And Impact Crusher

The difference between counterattack crusher and impact crusher

Counterattack crusher and impact crusher are two commonly used crushing equipment in mining, construction and other fields. They have certain differences in working principles, structural characteristics, and application scope. The following is a detailed analysis of these two types of crushers:

1、 Counterattack crusher

1. Working principle

The working principle of a counterattack crusher is based on the impact crushing of materials on a high-speed rotating rotor and the mutual impact crushing between materials. When the material enters the crusher, it is first hit by the plate hammer on the high-speed rotating rotor, and the material is crushed by the first impact. Subsequently, the crushed material is thrown towards the counterattack plate and subjected to impact crushing again. The material repeatedly collides and breaks between the rotor and the counterattack plate until it reaches the desired particle size.

2. Structural characteristics

The impact crusher is mainly composed of feed inlet, rotor, impact plate, discharge outlet, transmission device, and frame. Its structural design is reasonable, its operation is stable and reliable, it can handle materials with high moisture content, and its crushing efficiency is high, resulting in uniform particle size of the finished product.

3. Application scope

The impact crusher is mainly used for fine crushing operations and can handle materials with side lengths of 100-500 millimeters or less. In the entire crushing process, it is usually located after the jaw crusher as a secondary crushing equipment, cooperating with the jaw crusher for crushing. Widely used in mining, construction, transportation and other fields.

2、 Impact crusher

1. Working principle

The working principle of the impact crusher is that the material enters the crushing chamber through the feeder, and under the drive of the high-speed rotating turntable, it collides with another part of the material diverted around the turntable at high speed in an umbrella shape for high-density crushing. After the stones collide with each other, a vortex motion will be formed between the turntable and the shell, resulting in repeated mutual strikes, friction, and rolling, and then discharged from the lower part. Multiple closed-loop cycles are formed, and the required particle size is controlled by the screening equipment.

2. Structural characteristics

The impact crusher, also known as the sand making machine, is a vertical impact crusher composed of seven parts: a feeding hopper, a distributor, a vortex crushing chamber, an impeller experience, a main shaft assembly, a base transmission device, and a motor. Its structure is novel, unique, and balanced in operation; Low energy consumption, high yield, and high crushing ratio; The device has a small size, easy operation, and convenient installation and maintenance.

3. Performance characteristics

Advanced technology, high efficiency and energy saving: The impact crusher adopts advanced crushing technology, which can achieve efficient and energy-saving crushing operations.

Good crushing effect: The processed finished product has good sand particle shape and shaping function, with a cubic shape and high packing density.

Wear resistant and durable: The equipment is made of special materials inside, which have strong wear resistance and durability.

Easy to operate: The device is small in size, easy to operate, and easy to install and maintain.

4. Scope of application

The impact crusher is widely used in the fine crushing operation of various ores and is one of the important crushing equipment in mining, construction and other fields.

In summary, both counterattack crushers and impact crushers have their own advantages in crushing operations. The choice of crusher should be comprehensively considered based on specific material properties, production requirements, and economic conditions.
