Secondary Belt Cleaner
The Wash Box is installed as a secondary belt cleaner and is designed to work on the return side of the conveyor belt. Each steel enclosed box is equipped with a combination of pressure rollers, spray bars, and Razor-Back belt cleaners. It can also be customized to meet exact needs. The nozzles apply a spray of water that softens the carry-back and lubricates to maintain effective cleaning pressure. The system provides excellent cleaning while containing the wash waste fluid. There is a removable inspection and service door on each side, with washdown hose.
ASGCO Manufacturing Inc., Allentown, PA 18102 610-821-0210 www.asgco.com
The Swinglink heavy-duty bucket elevator is used for industrial applications such as soap/detergents, ceramics, ammunition, fiberglass, talc powder, sugar, salt, chemicals, fertilizer, glass cullet, and metal powders. It has buckets that remain in an upward facing position while loading and throughout the circuit allowing the material to have maximum gentle handling. When in a horizontal position, the buckets are overlapped to ensure there is no product spillage and the smooth bucket surface eliminates product trap areas. This provides a means of transfer in a single plane. Heavy-duty buckets are available in stainless steel, carbon steel, and plastic.

Sanitary Slat Conveyors
These slat conveyors are ideal for food products that require a high level of sanitation and minimal product degradation. Gently and quietly transporting products uphill, downhill, or horizontally, they can be employed for either short- or long-distance conveying. Featuring a simple design, these conveyors require little maintenance. The slats are available in a wide range of widths and materials and attached to chains that glide on special sanitary UHMW polyethylene chain rails designed to provide precise tracking. The most common construction of the slat conveyor for a sanitary environment is stainless steel.

Flexible Screw Conveyors
These flexible screw conveyors feed powder and bulk materials to and from packaging lines, bulk bag unloaders/fillers, processing equipment, weighing equipment, and storage vessels, all dust-free. They transport large pellets to submicron powders including free-flowing and non-free-flowing products that pack, cake, plug, smear, or fluidize—with no separation of blends—vertically, horizontally, or at any angle. The rugged screw is the only moving part contacting material, resulting in reduced maintenance and increased reliability. A cap at the bottom end of the conveyor tube can be removed for in-place flushing of the smooth interior surfaces, or for removal of the screw for sanitizing. They are available to food, dairy, pharmaceutical, or industrial standards in stationary and mobile configurations.

Conveyor Monitoring System
SmartArm is a wireless performance monitoring system for Iso-Flo vibratory conveyors that enables users to monitor asset or equipment shaker condition at any computer workstation. The system measures and reports speed and stroke to provide real-time analysis of shaker function, line-flow conditions, and trends at-a-glance. The SmartArm client also shows an alert when speed or stroke are out of tolerance. Empowering the shift from traditional time-based preventive maintenance to condition-based predictive maintenance, the system not only prevents downtime and reduces labor, but it also provides the opportunity to improve process efficiencies.

Heavy-Duty Flexible Conveyors
The Flexifeeder line of flexible screw conveyors offers an expanded capability with less frequent maintenance. Each unit is matched to individual customer requirements using both the company’s installation database and complimentary lab testing. The use of controlled vibration at the inlet hopper eliminates material packing and tunneling and encourages more even loading of the conveying screw. Along with a simple robust drive system, this results in a more uniform repeatable conveying rate and reduced maintenance. Flexifeeders are available at capacities up to 1500 cu ft/hr and single unit conveying lengths of 50 ft.
