New Pulverizer Helps PVC Processor Boost Output
New unit from Pallmann converts PVC scrap and delivers 2000 lb/hr of recycled PVC at 20 mesh (840 micron) particle size.
The installation of a new pulverizing system has enabled a leading PVC extrusion processor to expand capacity. The new pulverizer, model PKM800 from Pallmann Industries, 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, which Pallmann did not identify, 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, v.p. sales for Pallmann Industries. “We’re thrilled we could supply a key customer with a cost-effective solution with minimal energy requirements and maintenance, while at the same time providing a cleaner work environment,” said Taylor,
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 thereby are said to provide exceptional durability with many pulverizing systems boasting over 30 yr of service.
