Technical details and manufacturing context for Rotating Grate/Discharge Table

Definition
The Rotating Grate/Discharge Table is a critical component of industrial discharge systems, typically installed at the outlet of processing equipment such as kilns, furnaces, or reactors. Its primary function is to receive processed materials (e.g., sintered ore, clinker, pellets, or processed solids) and, through controlled rotation, evenly distribute and discharge them onto subsequent conveyors or into collection points. This ensures uniform material flow, prevents clogging, and aids in cooling or further processing stages.
Working Principle
The table rotates on a central axis, driven by an electric motor through a gear reducer. Processed materials fall onto the rotating surface. Centrifugal force and often integrated scrapers or plows guide the material outward to the perimeter, where it discharges over the edge. The rotation speed is adjustable to control the discharge rate and distribution pattern.
Common Materials
Heat-resistant cast steel, Alloy steel
