Guardian ^® Series Powder Blender
Process Control Corporation has incorporated the popular PF Series powder feeder into our line of Guardian ^® gravimetric batch blending systems. The Guardian ^® blender is ideal for applications requiring agitation mixing for complete dispersion and coating of the powder/pellet/regrind mixture. The powder feeder is an auger type, which is ideal for feeding non-flowable powder materials such as talc and blowing agents. This feeder allows processors to accurately meter and blend non-flowable materials with standard pellets and regrinds at a very economical price. The powder feeder element is constructed of polished stainless steel and incorporates two drive systems. The first accurately meters the powder material into the Guardian ^® weigh hopper while the second agitates the powder above the feed screw to prevent material bridging and rat-holing in the hopper. The powder feeder element can be easily removed from the blender for quick clean-out and material changeover. It can be incorporated into all four sizes of the Guardian ^® blender family (1.25 kg, 2.5 kg, 5 kg and 12 kg) for throughputs up to 4,000 PPH and a maximum of 12 components per blender.
