Star Feeders and Rotary Airlocks
 

 

Star feeders or rotary airlocks consist of a paddle wheel-shaped rotor that rotates at low rpm to dispense material into a hopper or process unit (e.g., crushers, screener, and mixers). If the blades form a tight seal against the valve wall, the valves can be applied in airlock applications. For example, an airlock valve is required if the process or conveying unit is at a higher or lower pressure than the pressure in the feeder. Rotary airlocks come in drop-through, blow-through or side entry variations. Star feeders, star feeder gates, rotary solids valves, rotary bulk material valves, rotary airlocks, or rotary airlocks valves are used to describe these types of feed or flow-assisting devices.


Products & Services
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.
Solids valves are used to control or regulate the flow of powder, granular and other bulk solid materials along a process line, or to and from process units, storage bins, conveyors and product packaging.
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 supply continuous or discrete lengths of bar, strip, wire or other stock to a machine tool.
Industrial valves are classified in many different ways. They can be distinguished by material of construction, media handled, and/or application.
