Impact crusher

Impact Crusher (Impact Crusher), also known as impact crusher, is a kind of crushing equipment widely used in many industries.The following is a detailed introduction to the impact crusher：

I. Definitions and classifications

Impact crusher is a kind of equipment that uses a hammer head on a high-speed rotating rotor to impact and crush materials.Depending on the structure and purpose, impact crushers can be divided into various types such as single-rotor impact crushers and double-rotor impact crushers.

II. Principle of operation

The working principle of the counterattack crusher is to use a high-speed rotating counterattack plate to impact the material block. The material block bounced back from the counterattack plate and the material block hit later strongly hit each other, and the material was repeatedly subjected to a strong impact in the crushing chamber, which was broken into a product of the required particle size.At the same time, the material is also affected by the shear and friction of the wall of the crushing cavity, which further promotes the crushing effect.

III. Structural components

The impact crusher is mainly composed of frame, transmission mechanism, rotor, hammer head, impact plate, square steel, impact liner, clamshell device, spindle, rotor frame, liner, locking block, compression block and other parts.Among them, the rotor is the core component of the crusher, which is driven by a motor to rotate at high speed; the hammer head is fixed to the rotor to impact and crush the material; the counterattack plate bears the impact of the material hit by the hammer head, causing the material to be broken by the impact, and the broken material is bounced back to the impact zone for crushing again.

IV. Features and advantages

1. Strong structure: The impact crusher adopts a sturdy steel plate structure and a heavy-duty rotor design, which has high compressive strength and wear resistance, and can handle materials of various hardness and strength.
2. High crushing efficiency: The impact crusher has a large inlet and crushing chamber, which can efficiently crush the material to the required particle size.At the same time, it also has a high-speed rotating rotor and impact plate, which can produce a strong impact force and crushing effect, and improve the crushing efficiency.
3. 能耗低: The impact crusher adopts energy-saving design and optimized power system, which can reduce energy consumption while ensuring the crushing effect.
4. Uniformity of product particle size: By adjusting the gap between the discharge port and the counterattack plate, the counterattack crusher can control the crushing particle size of the material to produce a uniform crushing product.
5. Strong adaptability: Impact crusher is suitable for crushing a variety of materials, including ore, construction waste, limestone, quartz sand, etc.It can be adjusted and optimized according to the characteristics of different materials to obtain the best crushing effect.
6. Easy maintenance: The maintenance of impact crushers is relatively simple, and usually only requires regular inspection and replacement of wearing parts, such as impact plates and liners.In addition, some impact crushers are also equipped with intelligent monitoring systems, which can monitor the working status of the equipment in real time and improve the reliability and maintenance efficiency of the equipment.

V. Areas of application

Impact crushers are widely used in metallurgy, chemical industry, building materials, hydropower and other industries, especially suitable for material processing occasions that require frequent relocation operations, such as highway, railway, hydropower engineering and other mobile stone operations.It can adopt a variety of configuration forms according to the type, scale and finished material requirements of the processed raw materials to meet the needs of crushing equipment in different fields.

VI. Operation and maintenance

In order to ensure the normal operation and safe operation of the impact crusher, the operators must operate in strict accordance with the operating procedures and maintain the equipment.This includes regularly checking whether the fasteners of the equipment are loose, whether the easy-to-wear parts are worn too much, etc., and solving the problem in time.At the same time, it is also necessary to pay attention to the working conditions of the lubrication system, add lubricating grease regularly and replace new lubricating oil regularly.During operation, uniform feeding should be maintained to prevent large pieces of materials and non-broken materials that exceed the requirements from entering the machine.In addition, the size of the gap between the counterattack plate and the hammer needs to be adjusted according to the nature of the material and the requirements of the product particle size to obtain the best crushing effect.

In summary, impact crushers play an important role in many industries with their efficient crushing capacity, excellent finished product shape and good adaptability.
