When the impact crusher is produced, the impact time is a factor that be considered. This determines the crushing efficiency of the impact crusher. In short, the impact time refers to the duration from the release of the impact to the contact separation. What are the factors that affect the crushing efficiency of the crusher under analysis?
1. The particle size of the material, select rocks of different particle sizes, and analyze the obtained impact time. The larger the material diameter, the the impact time. And the impact time-impact velocity curves between materials of different particle sizes are basically parallel.
2. Impact speed, change the size of impact speed, other conditions remain unchanged, analyze the impact time under different impact speeds, and find that the impact time does not vary with the increase of impact speed, and the impact speed and impact time are basically the same. Linear relationship. The impact time is shorter at a smaller impact speed. 3. The shape of the material, the shape of the material may be various and extremely irregular. Through the analysis of the impact time when the shape of the material is different, it is concluded that as the side length of the material increases, that is, the shape becomes larger, the impact time also increases. However, the impact time between rocks with the same grain size and different shapes is not much different, and the comparability is not strong.
4. When the wear of the blow hammer is different, the impact time does not always change , so the impact time is less affected.
