Adjustable Hopper Slider for Flexible Material Feed Rate Control

Hopper slider provides adjustable material flow control from storage hoppers. The movable gate allows fine adjustment of feed opening. Stainless steel construction resists corrosion and maintains material purity. Easy installation on standard hoppers without modification. Smooth gate adjustment mechanism for precise feed rate control. Sealing gaskets prevent material leakage at the adjustment point.

The hopper slider is a material feeding accessory that provides adjustable material flow control from storage hoppers to processing machine feed throats. In injection molding operations running multiple compounds or colors through the same machine, the hopper slider enables quick material changeover by directing material flow from one source to another without stopping production. For extrusion lines requiring controlled material feeding rates, the slider provides a simple mechanical adjustment of the material feed opening to match the extruder's output requirements. Mold makers use hopper sliders on small compound mixing setups to control the ratio of base resin to additive or color concentrate. The adjustable throat opening accommodates different material flow rates and hopper sizes, providing flexibility in material handling configurations without requiring complete hopper replacement. The slider mechanism allows the operator to make fine adjustments to the material feed rate during production to optimize extruder output or injection shot weights.
