Impact crushers mainly use impact energy to crush materials.It consists of components such as the chassis, rotor and counterattack plate.After the material enters, it is broken by the impact of the plate hammer driven by the high-speed rotating rotor, and then it is bounced back to the counterattack plate and broken again.Its crushing ratio is large and the particle size of the product is uniform.It is suitable for crushing materials of medium hardness and below, and is widely used in mining, construction and other industries.The impact crusher has a simple structure, easy operation, can effectively improve production efficiency and reduce production costs. It is an important material crushing equipment.

How to solve the over-crushing problem of impact crusher?

1.Adjust the gap.By adjusting the gap between the counterattack plate and the rotor, the degree of crushing of the material can be controlled.Appropriately increasing the gap can reduce over-crushing.

2.Optimize the speed.Reducing the speed of the rotor can reduce the number of shocks to the material, thereby reducing the occurrence of over-crushing.

3.Adjust the hammer head.Choose the appropriate hammer shape and material to adapt to different material hardness and particle size requirements and avoid excessive crushing.

4.Control the particle size of the feed.Ensure that the particle size of the feed is within the range specified by the impact crusher, and avoid too fine materials from entering the crusher, thereby reducing the chance of over-crushing.

5.Feed evenly.A uniform and continuous feeding method is adopted to avoid the accumulation of materials in the crushing chamber caused by a large amount of one-time feeding, resulting in excessive crushing.

6.Adjust the crushing grade.By adjusting the spacing between the counterattack plates of different levels, the residence time of the material in the crushing chamber of the counterattack crusher can be controlled to reduce over-crushing.

7.Use grading equipment.Add grading equipment (such as vibrating screens) at the back end of the crusher to separate the too fine materials in advance to avoid them from continuing to participate in crushing.

How to solve the problem of material stuck in the impact crusher?

1.Pre-screening.Before entering the crusher, the materials are pre-sieved to remove oversized pieces or materials that are not suitable for direct crushing.

2.Adjust the feed particle size.Strictly control the particle size of the feed to ensure that the material size does not exceed the design requirements of the impact crusher.

3.Optimize material humidity.Control the water content of the material to avoid excessive humidity that causes the material to bond and increases the risk of material stuck.

4.Improve the feeding method.Use a uniform feeding device, such as a vibrating feeder, to ensure uniform distribution of materials and reduce material accumulation.

5.Check the composition of the material.Regularly check the composition of the material, especially the hardness and toughness, to avoid impurities that are difficult to break during the crushing process.

6.Adjust the counterattack board.Adjust the position of the counterattack plate appropriately to change the crushing path of the material and reduce the chance of material stuck.

7.Clean up regularly.Clean up the interior of the impact crusher regularly to remove large pieces of material or foreign objects that may cause the material to get stuck.
