Powder King LLC of Anthem, Ariz., has announced its PKA Velocity Series of pulverizers, for rotational molding — the company's fourth generation.
The newly designed mill now has dual air inlets controlled by air damping valves to control the volume of air intake into each of inlets in the mill chamber. That doubles the amount of air intake into the mill's cutting chamber, according to Powder King President and owner Jim Hummel.
The mill also has dual material outlets, which takes the material out of each side of the mill to reduce residence time and heat buildup.
