How to ensure the durability of an impact crusher in granite processing?

Here are ways to ensure the durability of impact crushers in granite processing:

1.Select the right model:

1-1.Consider the scale of production: According to the expected granite processing volume, choose an impact crusher model with appropriate production capacity. If the processing volume demand is large, but a smaller model is selected, it will cause the equipment to be overloaded for a long time, accelerate wear and reduce durability.

1-2.Match the material characteristics: Granite is hard and abrasive, so you should choose a crusher that can handle this high-hardness material. For example, some impact crushers designed for hard rock crushing have structures and component materials that are more suitable for granite processing.

2.High-quality components:

2-1.Wear-resistant materials: Crusher's wearing parts such as hammers, impact plates, liners, etc. should be made of high-wear-resistant materials. Common ones include high-manganese steel, alloy steel, high-chromium cast iron, etc. These materials have good wear resistance and impact resistance, and can withstand the frequent impact and friction of granite.

2-2.High-quality bearings and transmission components: Bearings and transmission components are the key to ensuring the normal operation of the crusher. Selecting reliable and high-precision bearings and transmission devices can reduce vibration and noise during equipment operation, reduce component wear, and improve the overall stability and durability of the equipment.

3.Optimize operation:

3-1.Uniform feeding: Use appropriate feeding equipment, such as vibrating feeder, to ensure that granite enters the crusher evenly and continuously. Avoid local overload or idling caused by uneven feeding, and reduce uneven wear and impact of components.

3-2.Control feed size: Strictly control the particle size of granite entering the crusher, and do not exceed the maximum feed size specified by the equipment. Oversized materials will cause excessive impact on the feed port, plate hammer and other components of the crusher, causing damage.

3-3.Avoid entry of foreign objects such as iron parts: Install iron removal devices such as electromagnetic iron removers in front of the feed port to prevent non-crushed objects such as iron parts and stones from entering the crusher. These foreign objects may damage the components of the crusher and even cause equipment failure.

4.Precise maintenance:

4-1.Regular inspection: Develop a detailed inspection plan and regularly check the wear of various components of the crusher, including plate hammers, impact plates, liners, bearings, belts, etc. Timely discover components that are severely worn or show signs of damage so that they can be replaced or repaired in time.

4-2.Lubrication and maintenance: Lubricate each lubrication point of the crusher regularly according to the requirements of the equipment manufacturer. Use appropriate lubricating oil or grease and ensure that the lubrication system works properly to reduce friction between components and reduce wear.

4-3.Component repair and replacement: For worn but repairable components, such as hammers and impact plates, surfacing, spraying and other repair processes can be used to repair and restore their performance. When a component is worn beyond repair or reaches the end of its service life, it must be replaced in time to ensure the normal operation of the crusher.
