Jet Mill
The Open Manifold Design (OMD) Micronizer offers a solution to herbicide, pesticide, and insecticide manufacturers that require flexibility for the size reduction of multiple products. The OMD eliminates any hidden areas and allows the mill to be completely dis­assembled for cleaning. Having access to all internal areas allows the user to switch products without the risk of contamination and reduces turnaround time between the different powders. The mill can typically produce particle-size distributions between 1 and 20 µm.

Flow Enhancer
The patented Flow-Enhancer increases the capacity and efficiency of pneumatic conveying systems and reduces the conveying velocity and generation of dust and streamers. The latter can be achieved by air extraction, without changing conveying line size. Design features ensure easy retrofit into existing systems as well as the economical design of new systems. Key system benefits include decreased particle attrition due to reduced conveying velocities, decreased noise levels when conveying plastic pellets, increased pressure level for optimum efficiency without stepping the pipe, and optimized velocity profile throughout the entire conveying system.

Integrator for Belt Scales and Weigh Feeders
The BW500 is a full-feature integrator for use with both belt scales and weigh feeders. It operates with any belt scale with up to four strain-gauge load cells. It processes belt load and speed signals for accurate flow rate and totalized weight of bulk solids. It can take on lower-level control functions traditionally handled by other devices and supports popular industrial communication buses. Its patented load-cell balance function eliminates matching of load cells. The PID function may be used for rate control on shearing weigh feeders—where belt loading is constant—but can also control prefeeding devices. Operating in tandem with two or more weigh feeders, the unit can be used for ratio blending and controlling additives. Batching, load out, and alarm functions are also provided by the integrator.

High-Efficiency Cartridge Filter
The Ultra-Web nanofiber technology line now includes an even-higher-efficiency cartridge filter that delivers longer filter life, cleaner air, and greater energy savings. Ultra-Web SB, certified by independent lab tests at MERV 15 efficiency, is the latest extension of this dust collection technology that is backed by 80 issued and pending patents worldwide. The filter ships in 24 hours and is available as a replacement filter for the company’s cartridge dust collectors as well as all other popular dust collectors. It is suited for applications that face challenges from agglomerative dust in industries such as chemical, pharmaceutical, cosmetic, textile, and grain.

Two-Bearing Centrifugal Screener
The medium-capacity model MO Centri-Sifter centrifugal screener features a canti­levered shaft with two externally mounted bearings between the screening chamber and motor drive, allowing all internals to slide freely from the shaft end for cleaning, screen changes, or inspection. Wide spacing between the bearings, a large-diameter shaft, and a flexible shaft coupling combine to prevent vibration, even at high speeds under heavy, imbalanced loads. The new screener is intended for food, dairy, and pharmaceutical applications requiring thorough washdown, as well as other applications involving frequent screen changes and inspections or runs of multiple materials where cross-contamination is of concern.

Tank Lights
Jacoby-Tarbox Phaeton XTL tank lights combine simplicity with brilliance to provide bright, clean light for easy and safe viewing into any process vessel or storage tank. The new LED technology employed provides 33 times the brilliance of previous-generation LED lights, enough light to inspect inside even large tanks. The lights’ “view through” feature allows same-window viewing, eliminating the need for a second tank window by combining illumination and viewing in one. Because they consume less than 1 A, the lights stay cool to the touch, eliminating the potential hand- and face-burning hazard of old-style halogen inspection lights. They are rated for more than 10 years of continuous duty. No maintenance other than cleaning is needed.

Pneumatic Screw Pump
This pneumatic screw pump is a heavy-duty dry material injection pump designed to feed dry pulverized material into a pneumatic conveying line. It can handle highly abrasive, friable, or very fine powders that wear out other dilute-phase feeders. Unlike rotary airlocks that require tight clearances to seal against conveying air, the pump uses the materials to form the seal. An integrated gate prevents blowback, and the pump can handle temperatures up to 450°F. Other benefits include increased conveying rates with less air; no blowback, even when running empty; increased wear resistance to abrasive materials; low profile; longer bearing life with fewer system shutdowns; and overall reduced operating and maintenance costs.
