Pulverizing of brittle or tough plastics in a closed looped system for free flowing powders to be used for extrusion, rotomolding, and coating applications. Method of Operation The material in granular form is fed with a vibratory feeder from a feeding hopper to the pulverizer. The material is pulverized between the 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. A one pass system, without a sifter is also available.
 | Quality powders with excellent characteristics, high bulk density and uniform particle size |
| No material buildup in the machine housing |
| Precisely ground and hardened grinding elements with special serration, resharpening several times is possible, therefore extremely long service life |
| High throughput Capacity at low specific power requirements |
| Automatic production |
| Efficient air and water cooling of the machine. No contact between powder and water. |
| Easy access for maintenance and wear part change ApplicationsPulverizing of brittle or tough plastics in a closed looped system for free flowing powders to be used for extrusion, roto-molding, and coating applications.
