There may be all kinds of breakdown in the working process of impact crusher, such as superheating of bearing, abnormal vibration, oversized final product. The following are the reasons why the final products of impact crusher oversized. Impact crusher is one of the most common equipments in mining machinery industry, and it has the characteristics of high crushing ratio and good final product shape. The so-called iron ore deposit is the main target of industrial development and utilization. Iron ore beneficiation plant is generally divided into several stages, crushing, grinding, classification and separating. The current iron ores beneficiation plant generally is through the rock crushers crush the raw ore, then being extracted from the concentrate and tailings, and through chemical methods, and iron ore beneficiation products eventually become finished products.

1. The feeding size of impact crusher is oversized. Each type of impact crusher has its maximum feeding size. If we feed large stone in the impact crusher, it will be much difficult to crush the stone, which will leads to oversized final products. We should change the type of impact crusher and choose a more suitable crusher.

2. The space between impact plate and blow bar of impact crusher is too large. The final products of impact crusher can be adjusted by change the space between impact plate and blow bar. In this situation, we just need to adjust the space between impact plate and blow bar. As a result, Hongxing cone crusher has been the leading crushing equipment of the same kind since its emergence on the cone crusher market.


3. The heavy attrition of blow bar will also lead to the oversized final products of impact crusher. After the impact crusher works for a period of time, blow bar will have a heavy attrition, which results in a larger space between impact plate and blow bar. In this situation, the blow bar should be changed in time.
