PCS70 reciprocating Powder coating equipment Single-screw Extruder

PCS70-8D single-screw /single-rod extruder for powder coatings production line
---Suitable for large scale production. Technology has been improved based on Switzerland BUSS kneader.

Degold produce a new extruder with 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 3rows of pins with 120°angle 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, kneadered, re-set,loose mixing in the shear clearance among screw sheet, screw corner and pin, to reach the excellent dispension and distribution result. Reciprocating movement shear continuous process make shorter time of working process, nallower distribution of materials, lower temperature of products and excellent cleansing ability for products.
To satisfy customers' growing requirements on powder coating production.

Degold developed the enhanced version PCS--11D extruders, which are with stronger and higher effective during process of extruding than the previous 8D version.

Traits of PCS series extruder:
1. Compact design: feeding unit, driving unit and heating/cooling unit are intergrated; 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 recorganize screws according to the process requirements.
4.Improved dispersion: Screw rotation increased to 500r/min, allowing higher rate of dispersion and material flow.

Traits of PCS-11D version, besides previous 8D version:
1. Outpput increase under standard formulation.
2.Processing ability improvment for more demanding powder coating system with low viscosity and low filler cotent or under PT910 and Primid formulation.
3. High performance-price ratio.
4. Screw speed increased to 500-650r/min.
5. Process length extension 11L/D.
