This blast wheels are 100% fully machined parts.
The blast wheel has two side plates in order to assure perfect balance of the wheel and a perfect guidance of the abrasive flow.
The blast wheel side plates as well as the impeller, control cage and feed spout are constructed from highly wear resistant material.
This blast wheels have either 4 or 6 vanes, depending of the model. The vanes are made from an extremely wear resistance alloy.
The vanes of the blast wheels have a strong curve, both at the foot as well as on the end of the vane. The curve is calculated especially to have the maximum performance of the vanes.
The wheel housing is made from wear resistant steel, hardness 56 HRC. The wheel housing is protected on the inside with two wear plates on the side and three wear plates around. The wear plates around have a hardness of 65 HRC, the lateral wear plates, which suffer less wear have a hardness of 63HRC.
wearing time is 5-12 times longer then with conventional wheel.
