This minor ingredient batching system for rubber products consists of (13) small vibratory feeders and (3) 2-speed precision volumetric screw feeders, manufactured in 304 stainless steel. The selection of feeder type was accomplished via testing at the manufacturer’s facility. Each product was tested and the type of feeder selected for accuracy and flowability.
Small Vibratory Feeders
This powder blending system is used to mix dry ingredients by weight to create concrete products. Once the ingredients are unloaded into the system, they are conveyed to an industrial mixer.
The equipment consists of a big bag unloader on tank-type load cells, a 50 pound bag dump station with self-contained dust collector, a twin motor vibratory 2-speed feeder with an inclined corrugated side wall, and a cleated belt conveyor. All equipment was designed for dust-tight operation.
A bulk bag unloading system, containing (3) unloader stations, precisely dispenses additives into a blending and mixing system. Each station contains an over head rail with a powered hoist and trolley to lift the bag transport frame and bulk bag into each station.
Under the bulk bag is an untie hopper and delumper to remove any lumps before entering a vibratory feeder. The feeder meters the powdered material into a pneumatic conveyor. The pneumatic conveyor then transfers the material to a weigh hopper located above the blending and mixing system.
