Segregation of particles in powder blends can cause serious problems, resulting in reduced product quality, dissatisfied customers, the need to rework or scrap the batch, missed deliveries, and additional disposal costs. The gentle-handling TipTrak can help eliminate segregation by running horizontally, vertically, and horizontally without risky transfer points. The mixture remains in the buckets until it is discharged to the next process. Interlocking buckets never come apart, guaranteeing that spillage or product loss will not occur during the elevation process.

Capacitance Point Level Sensors
TrueCap RF-capacitance point level sensors do not have moving parts such as rotary paddle bin indicators or other mechanical-type level switches. They are sensitive enough for virtually any powder and bulk solid material and can be used on slurries. The TrueCap family includes a variety of probe types to meet virtually every application in feed and grain. In addition, high-sensitivity and automatic build-up immunity make the units high performers. The Model MK2 uses a universal power supply, push-button calibration, and built-in temperature sensors for automatic calibration compensation. The Model MK2e is based on standard analog electronic technology with a simple two-step calibration and cost-effective design.
Monitor Technologies LLC, Elburn, IL 800-766-6486 www.monitortech.com
With advanced coil technology, the PowerPhasePLUS RB metal detector has a wide aperture that is well suited for bulk bags, yet it can also inspect any dry, wet, loose, or packed bulk product.

The 48-in. Super Air Knife provides wide surface coverage, offering a way to clean, dry, or cool parts, webs, or conveyors. At 80 psig, the sound level is 69 dBA, a noise level 11 times quieter than ordinary blowoffs. The knife directs the compressed airflow to a precise, slotted orifice. It creates a uniform sheet of air across the entire length that immediately pulls in surrounding room air. Air amplification ratios (entrained air to compressed air) of 40:1 are produced. The knife achieves an air savings of 63% over typical blowoffs. Compressed-air inlets are provided on each end and the bottom of the knife for easy mounting. Multiple units can be mounted end to end without dead spots.

Membrane Filter Bags
These membrane filter bags are effective for dust-particle collection and emissions control. Because of the ePTFE membrane’s ability to integrate to the base filter media, the bags can achieve 99.99% filtration efficiency. Their smooth surface provides a primary dust cake, and the media’s lack of loose fiber ends provides a hydro- and oleophobic characteristic to provide a secondary cake release. The use of a membrane helps reduce emissions, lowers pressure drop, achieves longer bag life, reduces the need for cleaning, and saves energy.

The systems reduce installation time, increase the lifetime of the agglomerating elements, and reduce the cost of wear parts.
Pallmann Pulverizers Company, Inc., Clifton, NJ 973-471-1450 www.pallmannpulverizers.com
Manual Bag-Dump Stations
These manual bag-dump stations provide complete compact work areas to break and dump bags of material into conveying systems. Each station is equipped with a cartridge-filter dust collector, exhaust fan, and collecting hopper. As a bag of material empties into the unit, the airborne fines it produces are drawn away from the work area and conveyed into the cartridge. When the cartridge is reverse-pulse cleaned, the collected fines are released into the hopper and conveyed to the process, ensuring that 100% of the material is recovered and utilized. Standard features include heavy-duty steel construction, heavy-duty filter media, and manual cartridge cleaning. Optional features include hopper aeration, a self-cleaning timer, stainless-steel construction, a differential-pressure gauge, an extended work surface, interior coatings, a special discharge flange, a drum-dump hopper, and a door.

Shaft Seals for Screw Conveyors
Original MECO air-purged seals contain dry, abrasive bulk powders, pastes, and slurries in screw conveyors and other rotating equipment. They can increase mean time between failures by four or more times over packing glands (stuffing boxes) and can be quickly rebuilt on-site.

Designed to accommodate diametric shaft run-out of 6 mm and more, the seals are suited to horizontal or inclined screw conveyor applications. Both CEMA-standard and custom-engineered seals for conveyors are offered; suitability is determined by process conditions. Airflow rates are low in applications that require an air- or gas-purge line to be installed to the seal.

Bearing Protection Ring
This company offers a lifetime bearing protection guarantee for any new motor equipped with the Aegis SGR bearing protection ring. When the SGR is installed on a new ac motor (up to 100 hp/75 kW), the company guarantees that the motor will not fail from bearing damage resulting from electrical fluting. When a failure occurs, the company will pay to replace the bearings (up to 35% of the original motor cost). If not diverted, high-frequency shaft currents and circulating currents induced by variable frequency drives discharge through motor bearings. With multiple rows of conductive microfibers that surround the motor shaft and provide millions of discharge points, the ring safely channels harmful currents away from bearings to ground.
