Rail Car Unloading

Posted in: Blending, Process Control Corpration, Projects, Rail Car Unloading by Tony on November 27, 2009

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.

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.

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. This series is used in conjunction with the CH Series Transfer stations and the VL Series vacuum power unit.

Extrusion Control

Posted in: Blending, Extrusion Control, Process Control Corpration, Projects by Tony on

For complete control of mono or co-extrusion lines, PCC offers the Gravitrol® System. The Gravitrol® system takes the guess work out of extrusion control by continuously monitoring the mass throughput and adjusting the extruder screw speeds to maintain constant output by weight. With co-extrusion lines, Gravitrol® adjusts each extruder’s throughput to precisely control the percentages of each layer in the end product. With the addition of the Gravitrol® line speed device, the system can be further configured to control and maintain consistent weight per length of product.

EXB Central Operator Station
As the main component of the Gravitrol® system, the EXB operator station communicates with the HGB weigh hoppers and the EXD/EXL drive modules over a high speed serial interface. The EXB is the primary operator interface control panel where the recipes are entered and the complete system is controlled.

HGB Series Weigh Hoppers
Precisely and continuously monitoring the amount of material consumed by the extruder, the HGB Series weigh hopper, in essence, turns the extruder into a gravimetric metering device. The HGB sends a continuous stream of weight loss readings to the EXB central operator station for processing.
