The impact crusher is a new type of high-efficiency crushing equipment, which is characterized by: small size, simple structure, large crushing ratio, low energy consumption, large production capacity, uniform product particle size, and selective crushing. It is a very promising equipment; the impact crusher can process materials with a side length of less than 100-500 mm, with a maximum compressive strength of up to 350 MPa, a large crushing ratio, and the material is in cubic particles after crushing.

The impact crusher is a crushing machine that uses impact energy to crush materials. When the machine is working, driven by the motor, the rotor rotates at high speed. When the material enters the plate hammer action area, it hits 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 lining 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 for repeated crushing until the material is crushed to the required particle size and discharged from the discharge port. Adjusting the gap between the impact frame and the rotor can achieve the purpose of changing the material discharge particle size and shape.

Limestone is a soft ore and a common stone. Using an impact crusher to process limestone is an important part of limestone application in industry. The impact crusher has the characteristics of large processing capacity, good particle shape and good economy. Using an impact crusher to process limestone can shape it well and is the main source of building stones.

Specific characteristics of the impact crusher:

1. The back plate of the impact crusher rotor can withstand the extremely high moment of inertia of the rotor and the impact crushing force of the hammer.

2. The impact crusher has a large feed size and a small discharge size. The three crushing chambers are crushed in sequence to ensure production efficiency.

3. The impact crusher can reasonably adjust the grate bars to make the finished material reach the desired particle size.

4. The impact crusher has the function of stone shaping, which ensures that the needle-like content of the building aggregate is low.

5. The wear-resistant parts of the impact crusher are specially treated, and the impact angle is perfect, which effectively extends the life of the hammer and liner.

6. The impact crusher is equipped with a multifunctional hydraulic station, which has many functions such as hydraulic high-speed discharge gap, impact plate stability and vibration reduction, and automatic opening of the machine body.

Limestone processed by the impact crusher is mainly used in the construction market, while calcium carbonate used for industrial powder requires high-pressure grinding mills and ultra-fine grinding mills.
