Flexicon's High Flow Hopper, purposely-built for flexible screw conveyors, increases the flow of both free- and non-free-flowing bulk materials while eliminating or decreasing the amount of residual material in the hopper as well as the need for flow promotion devices.

The hopper is designed with a steep backwall and diametrically opposed sidewalls having panel sections which are skewed outward on a horizontal axis, forming a trapezoidal area. The divergent angles reduce the ability of non-free-flowing materials to establish a bridge between the hopper sidewalls, instead causing material to topple and flow toward and down the steep backwall.

The hopper walls converge to form a trapezoidal inlet to the conveyor interface adapter which also employs shear planes and vertical walls, to direct material into a rotating flexible screw more positively than with previous rectangular interface adapters.

The passive flow promotion attributes of the new hopper can eliminate the need for flow promotion devices such as vibrators and agitators.

The new configuration also increases usable hopper capacity by 5 to 19 percent, while reducing residual material in the hopper by 90 to 100 percent, depending on material flow characteristics.


Volumetric feeding

Flexicon flexible screw conveyors with volumetric feeding controls provide simultaneous metering and conveying of bulk solid products. The units are equipped with AC or DC variable speed drives and hoppers with flow promotion devices for continuous feeding of both free-and non-free-flowing materials.
