Round Separators
The ME Series is designed for projects that require an almost unlimited range of vertical and horizontal action intensities. It features a variable-speed pulley and a motor mounted on an adjustable slide base for precise control of frequency, providing accurate material travel and increased production. The ME rotational system—known as flywheel balance cages—assures exact control of lift/throw components. These balance cages rotate on a variable-speed shaft, allowing for finer adjustment and more efficient screening over a fixed rpm. Off-center weights in the balance cages produce eccentric throw. While some weights are bolted in position, others drop freely over spacer pins. The movable weights make it easy to change flow patterns to accommodate variations of product specifications.

Contract Screening Services
Company has expanded its toll processing facility to offer separations on many different products. Customers can now send any quantity to be screened on the Tumbler Screener or the Kroosher Multi Frequency Screener, which specialize in difficult-to-screen products that cannot be screened efficiently on conventional screeners. Examples are sticky products that blind screens, static products that will not screen efficiently, very fine powder separations and delicate agglomerates that need to be gently screened.

One-Way Rolling Blade Gate
The Rolling Blade Gate is a patented gate that offers superior sealing due to cam action; fast closing and opening; one internal moving part; curved blade to promote flow regulation; seals on the top, bottom and side of the gate, which help provide a seal for pressure or vacuum applications; cam action during blade closure, which forces the blade up into the seal at the closure point rather than running the blade along the seal; outboard bearings that protect the bearings from material contamination and provide a better shaft seal; and a curved blade design that allows the gate to be used as a metering valve. This gate is ideal for most applications where a rolling slide gate is used if headroom is available.

Mass Flow Feeder
The Mass Flow Feeder is a controllable high-capacity gravity feeder for relatively coarse granular materials. It consists of a mass flow hopper with two movable sides. The discharge rate is controlled by synchronous rotation of the two movable sides. The flow rate is a function of the discharge opening width and the slope of the blades. Minimum flow rate is limited by the opening width at which the material arches across the opening. Turndown rates of 10 to 1 can normally be expected. At a specific setting, the feeder discharges consistently with little variation. The rate varies with different materials and their flow properties. The feeder may be controlled manually or interconnected with a belt scale and programmable controller for automatic control.

Split-Frame Unloader
The Split Frame Unloader allows discharging of bulk bags and rigid totes from mezzanines and other low headroom areas. Unlike fixed-frame unloaders that require sufficient headroom above the top of the frame to clear the load backrest of a forklift, it allows the upper frame to be forklifted onto the plant floor, loaded with a bulk bag and then forklifted back onto the subframe within several inches/centimeters of the ceiling. For discharging from bulk bags, the subframe is equipped with a Power-Cincher flow control valve
that cinches the bag spout concentrically on a horizontal axis for easy tie-offs and vertically in a tight zigzag pattern to prevent leakage of fine powders. It also allows full-open discharge from bag spouts of all popular diameters and is USDA accepted.

Vibration Level Switches
Ideal for the level detection of bulk solids, the Optiswitch 3000 has a vibrating element—a tuning fork—that is energized piezoelectrically and vibrates at the mechanical resonance frequency. The piezos, which are fixed mechanically, are not subject to temperature shock limitations. When the tuning fork is immersed in the solid, the vibrating frequency changes and is detected by the integrated oscillator and converted into a switching command. The switch is virtually unaffected by chemical and physical properties, including density, conductivity, dielectric constant and viscosity. The switches guarantee continuous functionality when exposed to external vibrations and product variations by offering an integrated fault-monitoring system.

Manual Dumping Station with Flexible Screw Conveyor
This Manual Dumping Station with integral flexible screw conveyor collects dust created during manual dumping of powder and bulk solid materials from bags, boxes, drums and other containers. The unit 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 build-up on the outer filter surfaces to fall into the hopper. Filters are accessed easily by removing the interior baffle and replaced rapidly using quick-disconnect fittings. The flexible screw conveyor handles free- and non-free-flowing bulk materials ranging from large pellets to sub-
micron powders, including products that pack, cake, seize, smear, fluidize, break apart or separate.
Flexicon Corp., Bethlehem, PA 888-353-9426 www.flexicon.com
High-Temperature Bulk Powder Cooling System
This high-temperature model cools bulk solids with temperatures up to 1,832°F. For these high temperatures, the company developed a system using horizontal water-cooled tubes as the heat exchange surface. Bulk powder flows via gravity over the cooling tubes while being indirectly cooled. The geometry of the tube is uniform with even temperatures throughout the tube wall to avoid hot spots and high local stresses. The tubes are arranged in a serpentine design connected to manifolds at the top and bottom of each section. The tubes penetrate the front and back wall of the exchanger, with all-welded connections outside of the product flow. The tubes are not welded to the front and back walls to allow full movement. A product seal, where the tube penetrates the front and back walls, prevents product leakage. The front and back walls are typically refractory lined on the inside (product side) to keep the temperature of the walls low, minimizing thermal expansion.
Bulkflow Technologies, Calgary, Alberta, Canada 866-379-3500 www.bulkflow.com
Dosing Feeder
With gravimetric or volumetric control, the CD S70 provides its operator with the flexibility to meet changing process requirements. Ideally suited for dosing pellets, granulates, free-flowing regrinds and flakes, it provides a continuous and batching process. With a specially formed feed hopper that yields a large screw intake length, it ensures continuous material flow with no dead zones to provide a more consistent screw fill and accuracy. It can be used as a stand-alone feeder or it can be integrated with other feeding devices. All material contact surfaces are manufactured from corrosion-resistant 304 stainless steel, and the material seals are manufactured from Teflon and silicone.

Camera System
Providing real-time control-room monitoring of technical processing operations at a range of up to 1,000 meters, the Lumiglas Visulex Ex camera system saves on-site staff and travel time while enhancing quality control/assurance programs in hazardous locations. Visual process data can be continuously displayed in the control room on a standard monitor or a PC with image processing, or the data can be saved for later evaluation. The camera mounts directly on the process vessel, using a standard sight glass fitting (DIN 28120 or similar) with a hinged bracket. Readily installed on most existing systems, an upstream control unit provides power to the camera, regulates data transfer and, in some models, operates a zoom lens. In some instances, a secondary sight glass and an illumination source may also be added.
L.J. Star Inc., Twinsburg, OH 330-405-3040 www.ljstar.com
Weigh Belt Feeder
A complete line of low-capacity weigh belt feeders can operate in harsh industrial environments with minimal maintenance. The “MXL” weigh belts are specifically designed to meter a wide variety of hard-to-handle materials, such as potato chips and cotton fiber. Weighing is done through a patented low-deflection, nonwearing force measurement suspension system (FMSS) flexure scale that measures vertical loading and can take high load directed overloads. The FMSS Scale design uses counterweights to negate the tare weight of the weigh idler and the belt. One hundred percent of the scale capacity is thus used to weigh material, resulting in the best possible weight signal resolution.
