1. The design of deep cavity makes more space for the impeller which can improve the efficiency.


2. Reasonable inner structure makes the material protect itself, which makes the life of the impeller longer. And the cost will be lower.


3. There are different speeds (high, medium, low) to choose which can fully show the efficiency of the machine. It has the function of crushing, sand making and shape making.


4. The wear plate and hardfacing
