this month's topic Solids HandlingHydrofoil Impellers Reduce Power Requirements
HYFLO hydrofoil impellers can be used to upgrade a mixer or agitator to provide a very high flow-to-power ratio. They can provide twice as much flow as a 45-deg. pitched-blade impeller for the same amount of power, or provide equal flow for half the power. They have an efficient, stable 4-blade design that features tapered blades with a narrow, low-pitched section at the tip where the speed is fastest and a wider, higher-pitched section near the hub where it is slower. Models range in size from 3 in. to 210 in. dia., and can be made from Type 316 stainless steel, titanium and other alloys.

Bin Discharger Handles Difficult Materials
The FloMaster is a compact, totally enclosed, circular bin discharger that helps hoppers and silos process materials that are hard to control. Its rotating arch-breaker arm travels around the bottom of the hopper or silo to break any bridges of material that may have formed, ensuring material flow from the discharger to any of the manufac- turer’s single-stage or multi-stage units. The FloMaster is made of mild steel and can handle many different kinds of materials, from cocoa to wood flour, at a rate of up to 200 ton/h. Its two standard bin sizes are 32 in. and 40 in. dia.

Material Flow Aid Prevents Bridging and Ratholing
The ActiFlow smart bulk-solids activator is a non-product-contact device that prevents bridging and ratholing of cohesive bulk materials in stainless steel hoppers. It eliminates the need for mechanical agitators with secondary motors and gearboxes, as well as the need for flexible side-wall agitation devices or aeration pads. The self-tuning algorithm in the control module continuously monitors the system and adjusts the frequency and amplitude to maintain flow. The device is bolted to the outside of the hopper extension, above the feed screw conveyors, which simplifies cleaning during material change-over and reduces headroom requirements. It is suitable for applications in the food, pharmaceutical, plastics and chemical industries.
