How to Improve the Crushing Efficiency and Output of Water-Drop type Hammer Mill?

Adjusting the clearance between hammer and tooth plate or sieve: It is advisable to minimize the clearance between the hammer and the tooth plate or sieve to increase the frequency of hammer impact on materials and the circulation speed, thereby improving crushing efficiency. If the linear speed of the hammer does not match, it will reduce the working efficiency of the crusher and even cause the crusher to malfunction.
Installing a suction system: Adding a suction system in the crushing process makes it easier for materials to pass through the sieve holes, improving the screening efficiency of the crusher and reducing the pressure on the crushing link.
Controlling the moisture content of raw materials: Excessive moisture content in raw materials can affect the efficiency of drop-type hammer mills. Materials with excessive moisture are not easily crushed and are prone to clog the sieve holes, severely affecting the output of the crusher. Therefore, it is necessary to control the moisture content of raw materials to avoid excessive moisture affecting the crusher.
Ensuring uniform and smooth feeding: Feeding is the beginning of crushing, and if the feeding process is clogged or not smooth, it will affect the overall crushing efficiency. Therefore, it is important to ensure uniform and smooth feeding, equip with impeller feeders, and check if adjustments are needed inside the feeders.
Cleaning the discharge outlet and crushing chamber: Blockage of the discharge outlet will directly affect the discharge speed of the crusher, resulting in a decrease in output. Therefore, it is necessary to regularly clean the discharge outlet and the residual materials inside the crushing chamber to ensure smooth operation of the entire crushing process.
Optimizing the shape of the crushing chamber: To disrupt the circulation layer of the hammer mill and improve separation efficiency, the shape of the crushing chamber can be altered, such as droplet-shaped, octagonal, vortex-type, elliptical, etc. The droplet-shaped crushing chamber not only disrupts the circulation layer of the feed but also increases the effective screening area, facilitating the discharge of materials, and is therefore widely used.
Adding secondary crushing structure: Adding a secondary crushing structure in the crushing chamber, such as U-shaped or W-shaped, can significantly change the trajectory of feed particles and increase the feed output of the feed mill.

How to Solve the Wear Problem of Drop-type Hammer Mill when Crushing Different Materials?

Wear of hammers in drop-type hammer mills during the crushing of different materials is a common issue that needs to be addressed. To solve this problem, here are some suggestions:
1. Choose suitable hammers: The material and shape of the hammers have a significant impact on the performance and lifespan of the hammer mill. Therefore, when selecting hammers, factors such as the properties of the crushed materials (such as hardness, moisture, viscosity, etc.) and the wear resistance, strength, and toughness of the hammers should be taken into consideration.
2. Adjust hammer clearance: The clearance between the hammers and the screen affects the crushing effect greatly. Too large a clearance may result in incomplete material crushing, while too small a clearance may increase hammer wear. Therefore, the hammer clearance should be adjusted reasonably according to the properties of the materials and the crushing requirements.
3. Regularly inspect and replace hammers: Wear of hammers is inevitable, but it can be detected and addressed promptly through regular inspections. Once severe wear of the hammers is discovered, they should be replaced promptly to avoid further damage to the hammer mill.
4. Control the operating parameters of the mill: The operating parameters of the mill (such as speed, feed rate, etc.) also have a significant impact on hammer wear. Therefore, the operating parameters of the mill should be controlled reasonably according to the properties of the materials and the crushing requirements to reduce hammer wear.
5. Perform maintenance and upkeep of the mill: Regular cleaning, lubrication, and tightening of the mill can prolong the lifespan of the hammers and reduce wear issues.
