Types A, B and BX fabricated hammer mills

March 5, 2012

Types A, B and BX fabricated hammer mills use a series of hammer or ring blows to crush, grind and pulverize materials. They are useful for size-reduction applications involving alum cake, gypsum, limestone, salt cake, wood, and bran. Type A up-running mills feature 2-stage dual mechanical reduction, whereby the revolving hammers shatter materials upon entry, then the reduced pieces are further disintegrated by contact against the breaker plates. Type B down-running, heavy-duty mills use heavy, reversible hammers with the manufacturer’s saw-tooth breaker plate to produce uniform product.

Model EDP-500 palletizer

March 5, 2012

The fully automatic Model EDP-500 palletizer transfers empty drums from a conveyor and stacks them onto a pallet. This air-over-electric system can handle 30- to 55-gal steel, fiber or plastic drums, placing them in a 4-, 5- or 6 drum pattern on a pallet. The system’s average load time is 4 drums per min. An automatic pallet dispenser discharges a waiting pallet. Vacuum cups lower and raise the drums, and an overhead gantry shuttles the load to the drop-off station, where it is lowered onto a waiting pallet.

Vibroscreen Ultra-Sanitary Double-Deck Screener

March 5, 2012

The Vibroscreen Ultra-Sanitary Double-Deck Screener for scalping, de-dusting and dewatering of contamination-sensitive materials meets cGMP, 3-A, USDA and FDA standards. The unit features gap-free screen frames, quick-release “U” clamps, radius corners, a domed lid, an Air-Lift device to raise the frames, continuous ground and polished welds, a gap-free and crevice-free interior and a washable underside.

Hammer Mill Model 141

March 5, 2012

The Hammer Mill Model 141 reduces friable and fibrous materials into uniform particle sizes ranging from 20 to 300 mesh. Centrifugal force causes pivoting hammers to stand at 90-deg to the rotating shaft, throwing material against breaker plate ridges in the feed section, and then against perforated bed screens through which sized material exits.

MS Screener

March 5, 2012

Specifically designed to screen fine products at high capacity, the MS Screener provides excellent screening performance due to equal feed distribution to all screen decks, uniform bed-depth across the entire screen surface and a reduction in screen blinding due to the use of durable declogging balls. The stacked, multiple-deck, tray access design allows for individual screen access without the need to remove all decks. A patented Lift-Rail system enables easy installation and removal of the screen frame.

Powder Transfer System (PTS)

March 5, 2012

Powdered products that are either hazardous or subject to contamination when exposed to the workplace environment can be transferred safely by a self-contained Powder Transfer System (PTS). Designed for such products as pharmaceuticals, fine chemicals and metal powders, the totally sealed pneumatic system requires no external filters or vents, allowing dust-free charging of powder directly into closed vessels, including those under vacuum or pressure.

Hydraulic Bulk Bag Conditioner

March 5, 2012

The Hydraulic Bulk Bag Conditioner loosens bulk solid material that has solidified during storage and shipment, enabling bulk bag unloaders to discharge it through bag spouts. The conditioner features two hydraulic rams with specially-contoured end plates to press opposing sides of the bulk bags. An optional hydraulically-actuated, variable-height turntable allows in-frame bag rotation and conditioning of bulk bags at varying heights. The number and pressure of hydraulic ram actuations, the height of the turntable, and the number of 90-deg rotations are user adjustable.

Wet-Mix Process Systems

March 5, 2012

This firm’s Wet-Mix Process Systems provide users with a finished product that is homogeneous, has repeatable viscosity and dispersion down to one micron, and is consistent from batch-to-batch. Featuring a colloid mill and positive-displacement feed pump, systems can be designed for handling viscous materials from 1,000 cP and up, with flowrates from 0.5 to 300 gal/min, depending upon the application.

Vibratory Disk Mill RS 200

March 5, 2012

Well-suited for preparing samples for XRF or similar analyses, the Vibratory Disk Mill RS 200 features a powerful 1.5-kW stabilized plane drive that achieves grind sizes between 40 and 100 mm within seconds. The standard deviation of d90 values is only half compared to other disk mills. Samples of up to 250 ml with a maximum particle feed size of

C-Series line of vacuum conveyors

March 5, 2012

The C-Series line of vacuum conveyors are ideal for handling ingredients such as cocoa, sugar, powdered drink mixes, vitamins and coffee beans. Powered by the manufacturer’s pneumatically driven vacuum pumps, these systems safely and quietly transport up to 10–15 tons/h of powders and granules in virtually any manufacturing or processing environment. The vacuum conveyors are made from stainless steel AISI 316L and can cope with demanding circumstances. The filter design can trap particles down to 0.3 mm and can be equipped with a high-efficiency-particle-arrestment (HEPA) filter.
