Volkmann Inc. now offers three on-site, controlled weighing and dosing systems. Designed to be used in conjunction with its VS and PPC series of vacuum conveyors, these systems provide accurate batch weighing for processes such as feeding a mixer with solids according to a specified recipe, initial weighing of delivered raw material, unloading smaller batches from big bags, weighing of the receiving stirrer vessel, and measured conveying and weighing to ensure batch quality.
The three new systems include:
* Loss-in-weight at the conveyor feed point from bulk bag unloaders, hoppers, or bag dump rip and tip stations
* Gain-in-weight at the vacuum receiver prior to discharge into the process
* A controlled release, dosing weight discharge from the receiver via 4- or 6-in. stainless steel rotary valves using a floor scale or similar device
Single-, three-, and four-load cell configurations are available, depending upon application.
These systems can greatly improve production outcomes by registering weight within +/-1% or better, allowing adjustments to be made to avoid weight gains or losses during transfer. By utilizing a three-step weighing process, they eliminate errors that can occur due to the build up of material on filters, and other system parts. The +/-1% accuracy is a function of the application, batch size, installation, and process, but can often achieve greater accuracy after testing and adjustments.
The units include options for recipe management via the PLC controller and HMI and are available in 110v or 240v options. They can be set up to interface with SCADA and other data collection systems.
