The gap size between the hammers and sieve of the crusher should be determined according to the hardness and crushing requirements of the processed material, usually recommended between 0.5-2 millimeters. For specific materials such as grains, it is recommended to have a gap of 4-8 millimeters. The recommended gap for straw materials is 10-14 millimeters. These recommended values are based on practical experience and orthogonal experimental results, which can help improve crushing efficiency and extend equipment service life.
Crushers are indispensable equipment in many industries, especially in fields such as feed processing and biomass energy. The performance of the crusher largely depends on the design of its internal hammer and sieve plates, especially the size of the gap between them. This gap not only affects the crushing efficiency, but also relates to the service life of the equipment.
1. The relationship between gap size and crushing efficiency
The gap between the hammer and sieve has a direct impact on the crushing effect and efficiency of the crusher. The gap is too large, and the material cannot be fully impacted and ground by the hammer, resulting in low crushing efficiency. On the contrary, if the gap is too small, although it can increase the contact area and number of strikes between the material and the hammer, improve the crushing efficiency, it may also lead to premature wear of the hammer and sieve, and even material jamming and inability to pass, thereby affecting the normal operation of the equipment.
2. Recommended gap values for different materials
The gap size between the hammer and sieve should vary depending on the hardness and crushing requirements of the processed material. For cereal materials, due to their moderate hardness, it is recommended to have a gap between 4-8 millimeters, which can ensure high crushing efficiency and extend the service life of the hammer blade and sieve. For straw materials, due to their long fibers and strong toughness, it is recommended to have a gap between 10-14 millimeters to avoid entanglement or blockage during the crushing process.
3. Practical guidance and precautions
In practical use, operators should flexibly adjust the gap between the hammers and sieve according to the characteristics of the material and production requirements. In addition, regular inspection and replacement of severely worn hammers and screens are also key to maintaining the efficient operation of the crusher. By setting reasonable gaps and maintaining them properly, not only can the efficiency of the crusher be improved, but energy consumption and the possibility of malfunctions can also be reduced.
In summary, the gap size between the hammer beater and sieve of the crusher is a key factor affecting the crushing efficiency and service life. By following the recommended values and practical guidance principles mentioned above, users can better optimize the performance of the crusher and extend its service life.
