What is an impact crusher?

An impact crusher, also known as an impact crusher, is a crushing equipment widely used in many fields such as metallurgy, chemical industry, building materials, hydropower, etc. It is mainly used to process liquid stones, such as materials in highways, railways, hydropower projects, etc. It is also suitable for construction waste treatment projects in urban demolition, crushing and screening construction waste into aggregates of different sizes and rules, and realizing the resource reuse of construction waste.

Main features
Compact structure and small size: The impact crusher has a small size and compact structure, which is easy to transport and install.
High crushing ratio and high production capacity: The equipment can process materials with a side length of less than 100-500 mm, and the compressive strength can reach up to 350 MPa. After crushing, the material is in the form of cubic particles with uniform particle size.
Low energy consumption and high efficiency: The impact crusher adopts the principle of “stone hitting iron”, which not only has a large crushing ratio, but also low unit power consumption and high production efficiency.
Strong adaptability: According to the type, scale and finished material requirements of the processed raw materials, a variety of configuration forms can be adopted to meet the needs of different industries.
Easy maintenance: The equipment is reasonably designed, keyless connection, easy maintenance, economical and reliable.

Working principle
The working principle of the impact crusher is to use impact energy to crush materials. Driven by the motor, the rotor rotates at high speed. When the material enters the plate hammer action area, it collides with the plate hammer on the rotor and is crushed, and then thrown onto the impact device for crushing again, and then bounces back from the impact liner to the plate hammer action area for crushing again. This process is repeated, and the material enters the first, second, and third impact chambers from large to small and is repeatedly crushed until the material is crushed to the required particle size and discharged from the discharge port.

Application field
Impact crushers are widely used in building materials, ore crushing, railways, highways, energy, transportation, cement, mining, chemicals and other industries for medium and fine crushing of materials. The discharge particle size can be adjusted, and the crushing specifications are diversified, which can meet the material crushing needs of different industries.

Common types
According to different structures and performances, impact crushers can be divided into many types, such as single-rotor impact crushers, double-rotor impact crushers, PF impact crushers and HD German version impact crushers. These different types of impact crushers have their own characteristics in terms of processing capacity, feed size, and discharge size, and can be selected according to specific needs.

Matters needing attention
When using an impact crusher, you need to pay attention to the following points:

Regular maintenance: Regularly maintain and service the equipment to ensure the normal operation of the equipment.
Adjust the gap: Adjust the gap between the impact plate and the hammer according to production needs to achieve the ideal crushing effect.
Control the feed: Control the feed size and speed to avoid damage to the equipment caused by excessive or too fast feed.
Pay attention to safety: Pay attention to safety during operation to avoid accidents.
In summary, the impact crusher is a crushing equipment with the advantages of high efficiency, energy saving, and strong adaptability, and has broad application prospects in many fields.
