Net Weigh Scale

The Model 600NW net weigh scale combines a robust design with increased accuracy and high-speed operation. The unit is available in simplex or duplex configurations and can support automatic bagging when combined with a FFS machine or manual bagging on bag-hanging chutes. Simplex speeds on the base model in excess of 20 bpm and duplex speeds in excess of 40 bpm are possible. Gravity, belt, vibratory, gravity/vibratory, and other feeder types are available.

Powder Batching System

With many powder and bulk products, being able to consistently produce the same results every time is a necessity. This batching system uses DPF dosing feeders to achieve repeatability at high accuracy. The system pictured was designed to dispense a powdered pigment formula with an accuracy of 0.5 grams at high speed. The system had to be able to dispense up to a 5-lb batch at the 0.5-g accuracy, mix the powder ingredients with water, and transfer the material to the larger batching tank of concrete within five minutes. Dosing feeders can be used for high accuracy in packaging and screening applications as well.

Manual Batching Systems

These customizable batching and weighing systems are modular and tailored to customers’ production requirements. They are specifically engineered to adapt readily to future expansions and automation. System components include material silos, high-efficiency unloaders, and integrated dust collection. Dispensers are USDA-approved polyethylene for broadest application and best performance. Dispensers have a patented design feature that eliminates bridging, which works against the efficient flow of powdered material. Many systems also include a user interface, feeder conveyors, and precision metering and weighing devices.

Manual Dump to Rigid-Bin Weigh-Batching System

This system eliminates dust during manual dumping from bags, boxes, drums, and other containers, delumps the material, and feeds it gravimetrically from mezzanine level into rigid bins placed on a floor scale. It features a high-velocity vacuum fan that draws airborne dust from the operator’s atmosphere onto two cartridge filters. Automatic reverse-pulse filter cleaning allows continuous, efficient operation. Timer-activated solenoid valves release short blasts of compressed plant air inside cartridge filters, causing dust buildup on the outer filter surfaces to fall into the hopper. The unit’s surge hopper discharges into a low-profile delumping device with dual rotors and three-point heads that break up agglomerates that have formed in the bag. On-size material is discharged into a gravimetric feeder that is connected via PLC to a scale on the plant floor, allowing accurate batch weights to be loaded into rigid totes placed on the scale.

Heavy-Duty Balance

The easy-to-use K series balance features steel construction that makes it reliable in tough industrial environments. With a bright VFD display, an easy-to-use keyboard, and capacities from 12 to 32 kg with 0.1-g divisions, the unit is ideal for use in dry processing applications.

Batch/Dump Weighing Systems

The Model 403B(D) Batch/Dump Weighing System consists of a hopper for dry solids integrally mounted onto an overhead-type weighing (scale) system, specifically designed for reliable and accurate batch-weighing applications. For dry solids applications, product is typically fed into the scale-mounted hopper (weigh hopper) by a volumetric feeder. When it is required to batch-weigh more than one product in a single weigh hopper, each material is individually (sequentially) batched, since only one ingredient can be batch-weighed at a time.

Bulk-Filling Weigh Systems

The accurate and repeatable results obtained by this bulk-bag-filling station’s weigh systems are now NTEP-certified legal for trade. The certification process requires rigorous testing on each type of weigh system to prove their accuracy and repeatability over time. The company combines its NTEP-certified weigh systems with an advanced ergonomic operator interface and PLC-driven automated controls to provide its customers with state-of-the art bulk-filling system solutions.

Weigh Scale Modules

These Allen-Bradley–compatible weigh-scale modules read data from load cells and communicate net, gross, rate-of-change, and tare value weight data and status information over the I/O backplane to the Allen-Bradley processor. Mounted directly into the Allen-Bradley I/O chassis, these single- and dual-scale modules eliminate the need for any external communications link, reducing installation costs. The modules work with ControlLogix, Series 5, SLC 500, CompactLogix, and MicroLogix 1500 processors. All modules include Waversaver technology that ignores vibration around scales for fast and accurate weighing.
