Flat-Bottom Bin Discharger
The Model 170-BD-30 bin discharger utilizes mechanically induced internal agitation to promote the discharge of dry solid ingredients from within a bin or hopper, typically for filling a feeder or to refill a weight-loss weigh feeder. The discharger is a self-emptying design with complete and total clean-out capability. It consists of a circular, nonconverging, flat-bottom housing containing a horizontally mounted agitator (driven from beneath) for effectively discharging dry solid materials from within the storage bin or hopper to which it is attached. Product flows out of the storage bin and into the mating wide-throat opening, where the sweeping action of the slowly rotating agitator across the discharger’s flat bottom produces positive product discharge without compaction, attrition, or segregation.

Live Bottom-Bin Discharger
A live bottom-bin discharger has a 10-cu-ft storage hopper to meter needles to the mixing process. The unit eliminates all bridging and provides even flow to an 8 × 48–in. twin-motor vibratory feeder. The entire system is supplied with dust-tight covers and dust boots. The self-contained unit can be made portable for moving from one area to another.

Flow Discharge Aid
The Mucon Promo-Flow discharge aid is an easy-to-install solution to existing discharge problems. The custom-made, internally mounted screens are designed to transmit vibration directly into the product, preventing material bridging, rat holing, and segregation during discharge. The robust vibrators are mounted externally, activating the vibrating screens mounted on the inside of the silo wall at the points where the flow problem occurs. Rubber isolation mounts attach the discharge system to the silo, preventing leakage through the mounting holes. The whole unit is allowed to vibrate the product while contributing no vibration to the silo itself.

Dished Head Bin Activator
Exclusive features of this bin activator include a dished head contour, a forged hanger suspension system, a patented beaded sleeve, and an oil-lubricated gyrator. The unit mounts under any existing round storage silo or square storage silo, whether the silo is concrete or steel. An available oil-lubricated gyrator is maintenance-free and guaranteed for 20,000 hours of continuous use.

Bin Aerators
These aerators solve a variety of bin flow problems associated with difficult powders. The product line consists of the Rectangular Air Pad, Evasser, and Flo-Pad products. These devices offer different shapes and pressure ratings and provide different methods of diffusing the air. They are alternatives to using high-impact pneumatic or electric vibrators that can be loud and cause damage to the bin and surrounding equipment. In fact, bin vibrators can pack material instead of fluidizing it to address the problem. Typically used in applications where the material flow into the bin is via pneumatic conveying, the entrained air in the material is evacuated during the settling of the powder material.

Controlled Rate Discharger
The SolidsFlow Model 6000 controlled rate discharger discharges materials that have the tendency to compact, segregate, and bridge. This unit helps eliminate these problems by controlling material flow with a uniquely designed feed tray that accommodates the flow characteristics of the product being discharged. The tray works with the material’s natural angle of repose to prevent any flow when the feed tray is turned off. There is no spillage and no run-on. High-frequency, horizontal motion applied to the feed tray produces a consistent, uniform flow. Feed rates up to 1500 cu ft/hr are attainable.

Vibratory Bin Activator
The Hula-Hopper is an improved vibratory concept based on operating principles proven in hundreds of installations. Within a single, extremely-low-headroom unit, material activation, infinitely variable flow rate control, and positive flow shutoff are combined. Installation, service, and operating costs are lower than bin activators of other designs and are backed by a 100% process guarantee.

Bin Aerator
The Model K Vibra-Jet bin aerator can be installed on any storage silo, bin, or hopper as a versatile means of getting dry bulk materials, such as carbon black or fine cement, to gravity-feed more reliably at a low cost. Materials that tend to pack, bridge, or hang up can be made to flow freely and instantly on demand. A triple seal has been designed into the unit to prevent back feeding. This seal provides added reliability and extends the life of the unit.

Bin Activator
This bin activator instantly clears bins, hoppers, and other mass-flow vessels of compacted solids. It removes disruptive materials from channels, ducts, or recesses. The unit introduces multiple instantaneous sonic airbursts directly into compacted material to instantly restore flow, without severe shock and vibration methods that often damage equipment.
