Our Rail Car Unloading Systems have been design for optimizing the unloading of rail cars into resin storage silos and/or storage bins. PCC systems have been designed with the proper balance of maximizing the unloading rate and still maintaining the raw material integrity. Many years of experience in plastic processing enable our Project Engineers to accurately size each system to provide the most reliable and cost effective solution.

_	VP Series Vacuum-Pressure Power Unit As the most cost effective solution for conveying bulk materials, the VP series uses a single pump design in which the same blower is used for both vacuum and pressure and incorporates a central transfer station. This series is used in applications where conveying distances are generally shorter and the conveying rates required are not as demanding. Printable Specifications
_	VL Series Vacuum Power Unit The VL Series vacuum pump is the first part of a two-pump design rail car or truck unloading system. The VL Series is typically used in more demanding bulk conveying applications where the conveying distances are longer and the conveying rates are higher. This series is used in conjunction with CH Series Transfer stations and P Series Pressure Power Units. Printable Specifications
_	P Series Pressure Power Unit The P Series pressure power unit is the second part of a two-pump design rail car or truck unloading system. The two-pump design is typically specified when the single pump system cannot meet the desired conveying rates at the specified conveying distances.

Powder Feeders

Stand alone Powder Feeder for Individual Applications

Constructed completely of stainless steel, Process Control Powder Feeders can be used as either a stand-alone type feeder or as part of a continuous blending system for blending both powder and pellet materials together.

They utilize a single spiral hollow shaft auger actuated by a PWM type drive which uses a DC gearmotor with an encoder that delivers accurate motor speed feedback and allows the system to maintain a consistent RPM. The weighing system is designed with our new DSP (digital signal processing) technology (patent pending) to effectively filter out unwanted noise and vibration. The agitator within the powder feeder prevents material from bridging or clumping. Both the auger drive gearmotor and the agitator drive gearmotor are latched onto the hopper using quick-disconnect plugs so they can be quickly removed from the feeder for easy clean-out and material changeover.

Continuous Blender Powder Feeder

Continuous Blender Powder Feeder Designs

Process Control Corporation of Atlanta, GA is pleased to announce the release of a new continuous gravimetric blending system. The new design incorporates the PF Series powder feeders for use with non free-flowing materials. This new blender allows gravimetric blending of non-free-flowing powder materials with free-flowing powder and pellet materials.

The powder feeders allow feed rates as low as 0.2 PPH and as high as 3,000 PPH. The drive system of all blender components utilizes a PWM drive with a DC gearmotor and encoder for accurate motor speed feedback. This allows each of the individual feeders to maintain a constant RPM and weight throughput. The entire weighing system is designed with our new DSP (digital signal processing) technology (patent pending) to filter out unwanted noise and vibration which can wreak havoc with any feeding system, especially at very low feed rates.

This new gravimetric blending system has been designed to blend both free-flowing and non-flowing materials at unprecedented metering and mixing accuracy.

The X Series Powder Blender is also available in food grade stainless steel – consult factory for specific details!

Guardian® Series Powder Blender

Powder Feeders for Gravimetric Blenders

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.

HDA Dryer Hopper
The HDA Series Dryer Hopper is engineered to efficiently and completely dry hygroscopic materials. The dryer hopper is a critical component in resin drying systems, affecting both drying performance and energy efficiency. Poor hopper performance can result in wasted energy and incomplete drying of material. To sufficiently dry hygroscopic materials, every initially moist pellet must be subjected to a prescribed temperature and dewpoint atmosphere for a fixed time. This controlled environment lowers the moisture to a level suitable for processing.
