BUSS Operating Principle

Oscillating screw shaft, optimal mixing, extremely short processing length, superior temperature control.

The excellent mixing capabilities of BUSS Kneaders can be attributed to the unique operating principle which features simultaneous rotation and axial oscillation of the mixing and kneading screw shaft.

The oscillating screw shaft ensures intensive material exchange in an axial direction by multiple splitting, folding and reorientation of the product.

This results in an excellent distributive mixing effect and optimal distribution of the raw materials. BUSS Kneader Technology is particularly effective when liquid components have to be incorporated or high degree of fillers need to be added.
