PolyGrinder Systems For the PVC Industry

With controlled temperature, pneumatic conveying, and a vibratory screening system, designed to produce quality powder for the twin screw extrusion process.

• Space saving design

• Resharpenable segments

• Low energy consumption

• High capacities

• Automatic operation, PLC available

• Available in one-pass or closed-loop systems

• Four sizes to choose from

• External grinding gap adjustment

• Self contained unit

Applications:

Pulverizing rigid PVC pellets, pipe and profile regrind.  The powder quality produced with this system is excellent for high production, sensitive twin screw extrusion.  A constant feed assures higher extruder capacity and reduced wear on the screw and barrel.

Principle of Operation:

The material in pellet or granular form is fed with a vibratory feeder from a feeder hopper to the pulverizer.  The material is pulverized between two rings of segments mounted on carrier discs then air conveyed to a screening machine.  The coarse material is recycled to the pulverizer for further size reduction.  The desired powder is diverted to fill bags or containers or conveyed to silos.

Construction:

Heavy duty welded steel construction in compact space saving design.  The system can be designed to fit particular space requirements.

The front door is securely bolted and can be easily opened upon shut-down making the grinding chamber readily accessible for fast cleaning.  This door is fitted with a safety door locking system to prevent opening during operation.

The gap between the segments can be adjusted from the outside of the machine.  This enables setting the gap without shutting down the system.  The grinding segments can be resharpened for extended life.  The screening machine is selected in accordance to the specific application.  All system components are pre-assembled in the factory on common steel frames and disassembled into major components for shipping.  The pulverizing system can be put into service with a minimal amount of time and effort.

Decisive advantages:

• High Capacity

• Low Energy Consumption

• Automatic Production
