70mm Diameter Powder Coating Extruder Single Screw Kneader Machine

SGS Certified 70mm Extruder Diameter Powder Coating Production Single Screw Kneader

PCS70-8D single-screw/single-rod extruder for powder coating kneader is suitable for large scale batch production.


Our single screw extruders have novel screw design: Each circle of the screw rod is sectioned into 3 washer, which keep reciprocating motion during the swiveling of the screw rod and change to seesaw motion when the rod finishes one circle of rotation. As a result, a fierce shear action is generated between the rotary screw thread and the 3 rows of pins with 120° Angles which are mounted in the feeding container.

Frequency-converter screw reciprocating movement and adjustable shear force can optimize the mixing process as best. Materials can be cut, segment, kneader, re-set, loose mixing in the shear clearance among screw sheet, screw corner and pin, to reach the excellent dispersion and distribution result. Reciprocating shear continuous process make shorter time of working process, narrow distribution of materials, lower temperature of products and excellent cleansing ability for products.

Traits of PCS series extruder:
1. Compact design: Feeding unit, driving unit and heating/cooling unit are integrated; Delivered to customers as pre-assembled pipes and wires, therefore can be installed within a short time.
2. Double-screw sideways feeding unit: Allowing higher feeding rate.
3. Modular machining unit: Can replace and reorganize screws according to the process requirements.
4. Improved dispersion: Screw rotation increased to 500r/min, allowing higher rate of dispersion and material flow. The screw rotation speed of PCS70 is increasing to 650r/min.
