Manual Slide Gates for Hoppers

Manual slide gates for hoppers are widely used in industrial ventilation, dust collection, and material handling industries. Common applications include manufacturing plants, woodworking facilities, metalworking shops, grain handling operations, chemical processing, and any facility where controlled flow of bulk materials or airborne particulates is required.

Manual slide gates are commonly fabricated from carbon steel, galvanized steel, or stainless steel depending on the application requirements. The choice of material depends on factors such as the type of material being handled, environmental conditions, temperature range, and whether corrosion resistance is a priority for the installation.

Slide gate sizing is determined by the hopper outlet dimensions, the type and volume of material being controlled, and the flow rate requirements of the system. It is important to match the gate opening size to the hopper throat dimensions precisely. Duct Incorporated offers design assistance and technical support to help you identify the correct size for your application.

Yes, manual slide gates are commonly used in dust collection systems to control airflow and isolate sections of ductwork or hopper outlets. They provide a simple, cost-effective means of shutting off or regulating the flow of dust-laden air and collected particulates without the need for powered actuation components.

A slide gate and a blast gate damper function similarly — both use a sliding plate to control airflow or material flow — but blast gate dampers are more commonly associated with balancing airflow in dust collection ductwork branches. Slide gates on hoppers are typically used to control bulk material or particulate discharge at the hopper outlet rather than duct branch balancing.
