Vibratory solids feeders include impactors, rappers, bin activators, shakers, vibrators, vibrating bottoms or other mechanical activators are used to break arches or bridges in bins or hoppers and allow gravity-assisted flow to occur. The vibratory solids feeders' class of devices generally helps reduce flow restrictions from adhesion, rat holing, compacting or clogging. Impactors provide automation with a sledgehammer-type action. Shakers rock or tilt the whole bin. Vibrators impart vibrations into the bin using an unbalanced motor or an electromechanical vibrator. Some bin activators consist of a vibrated cone, which is placed beneath the bin to be discharged.


Products & Services
Solids Feeders
Solids feeders are used to deliver powder, granular and other bulk solid materials along a process line, or to and from process units, storage bins, conveyors and product packaging.
Bin Activators and Discharge Aids
Bin activators and discharge aids are solids feeder valves with integral vibrators to promote material flow and prevent material bridging. They are used to promote the steady flow of granular or powdered materials from storage bins, hoppers, or silos.
Bulk Material Loaders and Unloaders
Bulk materials loaders and unloaders are used to fill and remove powders, granular substances and other bulk solids from bags, bins, boxes, carts, drums, hoppers, railcars, trucks, and silos. They often include solids feeders and break down clumps or arches to allow for the more uniform distribution of bulk materials.
Stock and Strip Feeders
Stock feeders and strip feeders supply continuous or discrete lengths of bar, strip, wire or other stock to a machine tool.
Industrial Vibrators
Industrial vibrators use rotary or linear motion to provide consistent vibration for laboratory and industrial shakers, screeners and classifiers, and bins and hoppers. They are powered by an electric motor, pneumatic pistons, or hydraulic fluid.
