pbs0803p7a.jpgRotating Drum Magnet
Rotating drum magnets are designed for continuous self-cleaning of ferrous materials from product flow streams. As product enters the housing inlet, an adjustable feed gate meters the flow of product to the drum face. The drum has a stationary internal magnet with an outer drum that rotates. When product passes over the powerful magnetic field, ferrous materials are attracted to the drum surface where they are safely held onto until the ferrous material passes through the magnetic field, where it is discharged to the rear of the drum housing. Cleaned filtered product is discharged to the front of the drum housing.

pbs0803p7b.jpgAutomatic Gates
Industrial-grade AutoAire automatic gates can supply dust-collection air where and when it is needed, thereby “stretching” available air or eliminating wasted capacity. Solenoids (available in most voltages) control the air cylinders, opening and closing the gates as the machine or operation is turned on. The gates operate without individual controllers but can be tied to controllers, programmable logic controllers, or variable frequency drives to provide extensive system control. They are available in 3-in. and larger sizes.

pbs0803p7c.jpgBelt Conveyor
The 5200-series QWIK conveyor system comes with a completely contained belt. This design feature improves worker safety by eliminating catenary sag and reducing pinch points of the belt as it moves around the pulley and along the frame. The specially designed UHMW plastic hold-down strips contain the belt by wrapping around the ends of the conveyor, reducing the chances of getting a finger caught during operation. It allows end-users to modify the length, or even add or remove a curve, to adjust to changing applications.

pbs0803p10a.jpgAutomated Bulk Bag Discharger
This automated bulk bag discharger was designed to discharge contents from a bulk bag to the customer’s tote and from one bin to another. The simple and totally dust-free system includes a custom-designed hopper with a removable offset knife assembly that is designed to pierce and cut the bottom of the bulk bag around the spout. A dust-collection system is integrated to eliminate dust from the work area.

pbs0803p10b.jpgSanitary Pneumatic Conveyors
P-series conveyors (P10, P30, P100) provide a sanitary, custom solution for difficult conveying applications. Sanitary design features include steep cone angles to ensure excellent discharge and band clamps for quick disassembly. Typical materials include tablets, capsules, flakes, and free-flowing to poorly flowing powders, specifically materials that need gentle conveying. The systems perform pneumatic, vacuum, dilute-phase, and dense-phase conveying. Conveying rates vary depending on the model, product characteristics, and conveying distances.

pbs0803p10d.jpgDrum Separators
These drum separators remove both large and small pieces of iron contaminants from material processing lines. Powerful Erium permanent magnets separate ferromagnetic particles automatically, achieving high levels of purity in food, grain, chemicals, plastics, metals, rock products, ores, and more. Type CC/crisscross circuit drum separators ensure maximum tramp-iron removal in heavy-duty applications. The Type A/agitator-type drum automatically removes difficult-to-separate magnetic materials from nonmagnetic materials. The Type RE/rare-earth drum is used in applications in which a high degree of product purity is required. The Model HFP/drum-in housing with feed protection performs controlled feed and discharge functions.

pbs0803p11c.jpgVacuum Dryer
Equipped for multiple functionality, the Ploughshare vacuum dryer homogeneously mixes dry ingredients, injects liquids, and efficiently vacuum dries the material to a final product. The Ploughshare technology creates a mechanically fluidized-bed mix action that rapidly mixes the dry solids and facilitates the quick and even dispersion of the added liquids. Optimizing the drying process, the dryer’s high-speed choppers deagglomerate and control particle size. The unit can be configured with a heating jacket, a pulseback filter, and a vacuum system.

pbs0803p14a.jpgPharmaceutical Wraparound Labeling System
This heavy-duty labeling system was designed to apply wraparound labels to 3-ml and 10-ml cylindrical glass vials. To ensure accurate and consistent product handling, a custom wrap station and vertical roller assembly were designed specifically for this machine. The vertical roller assembly stabilizes and controls the glass vials and references the container sidewall as the label is being applied, minimizing the challenges of dimensionally inconsistent glass. The dual remote-powered unwind provides minimal label changeover time.

pbs0803p18b.jpgTilt Switch Probes
Series LTS tilt switch probes can sense either the presence or absence of material when other sensors do not work because of bin vibration or because actual walls are not available for mounting other types of measuring units. The probes are designed for use where the bulk material to be sensed is exposed or open. Typical applications include high- or low-level detection in large hoppers, silos, crushers or trippers, high-level control under stackers, and detection of plugged conditions at conveyor transfer points. The probes can also be used to detect the presence or absence of bulk material on belt conveyors, on chutes to indicate product flow, and to aid in loading rail cars or trucks.

pbs0803p22b.jpgHigh-Speed Mixer
The Jumbo Quik Mix combines a material-dispersing paddle with a direct-drive vertical auger to create a high-speed blending action that ensures complete uniform mixing of pellets, regrinds, color concentrates, and other free-flowing materials in 30 minutes or less for batches up to 25,000 lb. After the batch-mixing cycle is completed, the material is discharged into Gaylords or to a pneumatic conveying pickup point. The batch timer and motor controls are simple and easy to use, and the mixer’s rugged construction enables years of trouble-free operation in the harshest plant environments.

pbs0803p23a.jpgTilted Mixers
This company has introduced a new design option for its line of change-can mixers, including the PowerMix, double-planetary, VersaMix, and dual-shaft designs. The new tilting design allows automated discharge from a tilted mix can to a receptacle placed under the can on a bench. This feature simplifies the transfer of materials to secondary processes and eliminates the need for an operator to move the can from the mixing position. It also provides a completely accessible mix can for cleaning between batches. Shown is the PowerMix, which combines a powerful planetary mixing blade revolving in combination with a separate high-speed dispersion blade. Each revolves on its own axis as well as on a common axis, and each can have its speed varied independently of the other.

pbs0803p25b.jpgBulk Bag Discharger
The Universal Type 2 bulk bag discharger provides controllable discharge by volume of poor-flowing materials without wastage or spillage, increasing productivity and promoting a cleaner work environment. The unit controls flow by means of a highly accurate, highly repeatable integral flexible screw conveyor. Directly coupled to the base of the discharger, the conveyor meters the flow of big bag contents to the customer’s process vessel. The discharger is well suited for all big bag types, accommodating sizes up to 6 ft high and up to 2 tn in weight. A dust control connection facilitates linkage to the factory dust extraction system or to a local dust collector integrated with the discharger.

pbs0803p26a.jpgGravimetric Inventory Management System
The Gravimetric inventory management system weighs repelletized material prior to its being reprocessed or stored as inventory and can verify delivered resins before entering them into inventory. The system can be configured to operate in a continuous mode for loading silos or other surge bins for storage or as a batching system for loading Gaylord boxes for storage. It can provide totals for a given production shift, a complete production run, or an overall running total of material. Pellet material is conveyed either from a pelletizer, storage, or delivery unit into a surge hopper via a pressure or vacuum system. The surge hopper has a high-level view window for quick visual inspection of the material level within the bin, as well as a cleanout door and a high-level proximity sensor. The sensor shuts down the conveying system and prevents the system from overfilling. The material is then discharged from the surge hopper through a slide-gate into a weighed hopper. The material is discharged through a second metering gate into a Gaylord box or is conveyed to either a storage silo or storage bin via a vacuum or pressure system.
