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 can break down clumps or arches to allow for more uniform distribution of bulk materials. Some bulk materials loaders and unloaders are designed to handle abrasives or ceramics, chemicals or fertilizers, cosmetics or pharmaceuticals, construction materials or cement, food products, metals or minerals, and paints or pigments. Others are designed to handle pulp and paper, wood chips, polymers, adhesives, molding, coal, or wastewater sludge. Dry or free-flowing devices can handle a variety of dry materials. Wet or bridging devices can handle moist materials, slurries and dispersions; flakes and fibers; and other bridged materials with high aspect ratios.
