Surge Bins
Designed to integrate with inline processes, such as material filling and discharging, these bulk storage bins provide quickly accessible, in-plant storage of blended or virgin material. Heavy-duty dry bulk hopper and frame construction is 14-gauge carbon steel; Type 304 stainless-steel construction is also available. Surge bin capacities range from 700 to 18,000 cu ft. Various options for material
filling and discharging are available.

Blower Packages
The DB blower series is the latest member of the Com-paK Plus family. The DB 166C and DB 236C offer reduced footprint and simple installation and maintenance, as well as reduced noise and vibration. They also feature the new Omega Control Basic, which provides full control and package protection. The controller integrates motor starters and instrumentation, which reduces installation cost and provides assurance that the package will run the first time, and every time.

Conveyors
Engineered for long life, these bulk, package, and pallet conveyors operate within a wide range of industrial and agricultural applications. Multiple standard conveyor designs include flat and troughed, and slider and roller bed frames. The company utilizes belting with smooth or patterned surfaces for horizontal and incline applications, corrugated sidewall belts for steep incline applications, and flat wire and powered rollers for bag and pallet applications.

Enclosed Belt Conveyors
These belt conveyors for dry bulk materials are completely enclosed. All bearings are isolated from the internal atmosphere of the conveyor. Any dust or spilled product is contained within the enclosure and automatically reloaded back onto the carrying surface of the belt.

Laboratory Batch Mill
A conversion kit assembly is available for use with the 1-S attritor that will allow customers to retrofit the batch-type mill to a circulation-type mill. For certain applications, circulation grinding is preferred as it utilizes a high pumping rate that results in narrow particle-size distribution and good temperature control. Additional advantages of circulation milling include larger batch sizes using a smaller mill, savings in grinding media since less media is required, and easy formulation adjustments and sampling. The conversion kit is comprised of an upper discharge chamber, grid plate assembly, impeller, and agitator shaft/arm assembly. As with all circulation attritors, a pump and separate holding tank would be required.

Steel IBC
Robotic manufacturing of the Supertainer ensures consistent high-weld quality and container integrity. It is available in Type 304 or 316 stainless-steel or painted-carbon-steel, and in 180–790-gal sizes. A unique stamped heel-less bottom provides total drainage. Other features include lifting lugs, temperature control devices that can be integrated within the unit for heating and cooling requirements, multiple valve arrangements, and a three-way forklift for pallet jack and forklift access. A wide array of options and accessories are available to customize the Supertainer to fit the application and budget.

Aeromechanical Conveyor
This aeromechanical conveyor, or “rope and disk” conveyor, is a high-capacity, totally enclosed unit that can convey vertically up to 60 ft. The high-speed conveyor uses a disk mechanism that fluidizes all flowable solids in a recirculating airstream that provides low-shear conveying of powders or particulates up to 5/8 in. The unit can be used for difficult-to-convey materials such as abrasives and moist, sticky materials, or products that pack, cake, smear, or plug such as titanium dioxide.

Stainless-Steel Bag Dump Stations
These compact bag dump stations eliminate the labor, waste, and potential health hazards that may be caused by spillage or dust when handling bagged materials. The self-contained units are now available in sanitary, stainless-steel construction, which is ideal for food, feed, pharmaceutical, pet food, and other industries where contamination can be costly and dangerous. The systems range in size from 5 to 40 cu ft in capacity and are USDA accepted to collect dust generated when dumping powders and bulk solids from bags, boxes, drums, and other containers. The units then return the material
to the hopper.

Bag Dump Dust Collection System
This bag dump dust collection system reduces worker exposure to nuisance dust. A downdraft dust collection system helps protect the operator from dust produced by the screening process. The system is designed to work exclusively with the Sweco bag dumper, a system used to screen material at bag-unloading stations. The system improves particulate containment by providing vacuum below the bag dump screen, rather than above. This pulls dust down and away from the operator, improving airborne particulate flow into the collection system’s filters. The integrated system includes a low-profile separator for high-capacity dry scalping. The dust collection system features Type 304 stainless-steel construction, a hinged load door with dual-gas shock lifts, heavy-duty fan assembly, dual nonwoven spunbond polyester cartridge filters, and an integrated pulse cleaning system.

Easy-Open Pails
Twist and Lock pails open with a push of a tab and a twist of the cover. Closing is even easier: just twisting the lid locks it in place. This family of rigid packaging is fully compliant with all relevant UN requirements, along with child-resistance and senior-friendly protocols. Four decorating and labeling options are available: offset printing; silk-screen printing; pressure-sensitive labels; and heat transfer printing, which provides photo-quality graphics and a bar code scan rate of 100%.

Drum Filler
This automatic drum filler is designed to convert from 55- to 5-gal jugs and pails. The Model ADO-5520 is a dual-lance filler that automatically rotates each drum, locates and aligns the bung openings, positions each drum at six o’clock, then shuttles them to the fill station, where the tare and filling is also automatic. When converted to a twin-pail filler by a selector switch, this machine indexes two containers directly to the fill station, then tares and fills two 5-gal jugs simultaneously. The fill rate is 8 pails/min. Standard construction material is rugged, all-welded, structural-steel with Type 316 stainless steel for wetted parts. Additional standard equipment includes a drum indexer, a drum rotator, pneumatic locator, conveyors, and a flip-down twin pail indexer.

Gravimetric Feeder
The MGF gravimetric device for feeding colorants and additives into plastics processing machines has new capabilities, which include multilingual operator access and full data retrieval as standard features for all molding and extrusion applications. The unit also has a new extrusion following option. The optional extrusion following system automatically anticipates and adjusts for gross variations in extruder rate, like those during changes of film rolls.

Compaction Tables
Compaction tables are used to settle, compact, and consolidate material. These custom-made tables can settle contents quickly and easily, and get more into each container. They can reduce man-hours and shipping costs by up to 15% and increase production output. Installation of a table in-line on a conveyor belt is easily accomplished.
