Product Spotlight: Vacuum Receivers (Part 1)

Today’s product spotlight from PCC will be a special two part blog on our line of Vacuum Receivers for material handling. We will focus on proper receiver sizing and how it affects the blending system.

PCC manufactures a complete line of vacuum receivers for use in pneumatic conveying of plastic material. The RN Series is designed for plastic pellets and the RP Series for dusty materials like plastic regrind. When coupled with a vacuum pump and sequencing panel, vacuum receivers can provide automatic loading of blenders with multiple hoppers, surge hoppers, storage bins or other devices. Since a typical conveying system includes multiple receivers, for the system to operate efficiently, the receivers must be properly sized.

Properly sized receivers are even more critical in the case of continuous, loss in weight gravimetric blenders where the blender hoppers are sitting on load cells. In normal operation, the blender monitors the weight of the material in each hopper and adjusts the material feed rate accordingly to provide an accurate blend of material. When the receiver provides a dump of material to the hopper this can disturb the weight monitoring process. To compensate, the blender senses this disturbance and goes into coast mode temporarily. A properly sized receiver will provide a dump size that fills the hopper completely, without over filling, and minimizes these periods of disturbance providing increased accuracy. Over filling, caused by an over sized vacuum receiver, also disturbs the weighing process since the material backs up in the receiver and continues to drain into the hopper as material is removed.

New Literature for EMV Variable Speed Drive

Process Control has released new literature for the EMV Variable Speed Drive. Click here to download!

EMV

The EMV variable speed drive for our VF Series Vacuum Pump has the ability to slow down or speed up the pump to match the conveying requirements for each vacuum receiver station. By controlling the speed, not only does the drive allow the user to save energy, but it helps keep the material undamaged during the conveying process.

Special Manifold Distribution Station in Production

DSC_1505DSC_1506

Currently in production and shown above is a PCC manifold distribution station with forty-eight (48) pickups, featuring:

  • Twelve (12) horizontal rows by four (4) vertical columns outlet configuration
  • Equipped with quick disconnect male camlocks for fast material change
  • Material catch bin with drain
  • Heavy-duty stand design
  • Aluminum or stainless steel available
  • Other configurations and tube sizes available

PCC Vacuum Pump Upgraded with Variable Speed Drive

10HP VF Variable

VF Series Vacuum Pump with variable speed drive at our Atlanta, GA showroom

The vacuum system in Process Control’s showroom [Atlanta, GA] has recently been upgraded with a 10HP VF Series Vacuum Pump fitted with a variable speed drive.  The drive has the ability to slow down or speed up the pump to match the conveying requirements for each vacuum receiver station. By controlling the speed, not only does the drive allow the user to save energy, but it helps keep the material undamaged during the conveying process. The pump can also be slowed down during idle time to further save energy. The conveying speeds are easily controlled through PCC’s Director Sequencing panel [as seen in the images below].

Make More of Your Regrind

Mailer_Savings

Today’s blog energy features an article on how Process Control equipment can help blow molding processors make the most of their regrind.

Extrusion Control

Mailer_Gravitrol

We offer a complete Gravitrol extrusion control system for total weight and layer control. The system control can be integrated into a blender control, or provided as a stand alone system. We have engineered special 70 degree weigh hoppers specifically for regrind materials to make material flow seamlessly through the system.

Material Handling

RP Series Vacuum Receiver

In addition to standard material handling equipment, PCC offers our RP Series vacuum receiver for dusty, regrind materials. The tall design (pictured above) accomplishes cleaning with conveying air to avoid carry-over of dust back to the vacuum power unit. This special design keeps dust and fines as part of the process blend.

Batch Blending

12kg_regrind2

Process Control rises above the standard with our Guardian Series 2 gravimetric batch blender series. The G2 was developed for processors who want the simplicity of operation combined with the most accurate dispensing and superior blend homogeneity at a low cost. These features are especially important for blow molding processors, who want regrind materials to blend easily back into the system.

Guardian Series 2 blenders have a high capacity of up to 9,000 PPH. Steep-wall, fully-welded, individual element hoppers ensure the best flow of most regrind materials. Regrind element hoppers are available with auger discharge and bridge breaker for lighter regrind. The blender software can include a regrind mode for special recipe handling and better control.
