Conical twin screw

Brief introduction:

Screw adopts variable pitch, variable fit clearance, fine fluid mechanics calculation and other design concepts, so that the material in the conveying process of screw shear, mixing, compression more soft, more close to the actual production needs.

Specifications:

35/76, 45/90, 45/100, 50/105, 51/105, 55/110, 55/120, 60/125, 65/120, 65/132, 68/143, 70/135,70/140, 75/150, 80/143, 80/156, 92/188,

The above are standard specifications, which can be customized according to customer requirements.
