25/53 to 90/184 different direction to outside conical twin screw barrel

Specifications of standard twin conical screw and barrel:

45/90, 51/105, 55/110, 65/132, 80/156, 80/172, 92/188.

Advantages of Twin conical screw and barrel:

1.Advanced Nitriding Technology
2.Anti-corrosion and Wear-resisting Duplex Metal Spraying Technoloy

3. we uses special alloy powders being sprayed and welded on the screw's ridge,and uses

   different alloy and welding methods for the screw of different functions.

 

 

• Easy operation
• Optimum performance
• Durable
• Low power consumption
• Corrosion/wear resistance
