Pulverizer delivers higher productivity

The installation of a newly launched Pallmann PKM800 pulverizing system has enabled a leading manufacturer of PVC extrusions to expand capacity. The new pulverizer from Pallmann Industries, a leading global supplier of size reduction equipment for the plastics industry, delivers greater throughput, increased productivity, reduced material cost, and greater cleanliness for products made of PVC.

In response to the booming building and construction market, the PVC extruder needed to boost capacity to meet growing demand. The high-performance PKM800 pulverizer converts PVC scrap and delivers 2000 lb/hr of recycled PVC at 20 mesh (840 micron) particle size. These recycled powders are mixed with virgin PVC material and are re-entered into the profile extrusion process.

The PKM800 pulverizer outperforms the previous competitive model by 2 to 1 in terms of production, according to Jeff Taylor, vice president of sales for Pallmann Industries.  The PKM800 is safer and cleaner than competitive models thanks to a pulse jet enclosed bag housing that contains the dust. Unlike typical hanging filter bag plenums, the PKM800 blows air and discharges the dust downward into a container. 

The pulverizer also delivers uniform particle size distribution for production of more intricate and detailed profiles. High-quality powders can be produced and blemishes and pits are reduced in finished parts.

The PKM800 pulverizer features “segment” cutting technology which provides different serrations for different applications, unlike grinding rings which have limited serrations due to narrow inlet tooth distances. Segments offer a real scissor-cut action, affording better utilization of cutting energy, less heating, reduced fines, and adaptability to many materials.  Pallmann pulverizers are made of strong weldments instead of standard castings and thus provide exceptional durability with many pulverizing systems boasting over 30 years of service.
