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. 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. Typical specifications include a table diameter of 1000–3000 mm, rotation speed of 0.5–5 rpm, drive power of 2.2–15 kW, load capacity of 5–20 t, operating temperature of -20 to 200 °C, speed accuracy of ±2%, surface hardness of 45–55 HRC, material grades Q235B/304 (per GB/T 700 and GB/T 3280), IP rating of IP54–IP65 (per IEC 60529), and weight of 1500–8000 kg. These values are reference ranges and must be confirmed for the specific model and application. The table is typically made of heat-resistant cast steel or alloy steel. For selection, consider material characteristics, required throughput, and installation constraints. Verify interface dimensions, drive compatibility, and environmental conditions with the manufacturer. Regular maintenance includes checking wear on scrapers, seals, and bearings. Unusual noise, vibration, or reduced speed accuracy may indicate wear or misalignment. The table is designed for continuous operation within specified limits; exceeding temperature or load ratings can damage components. Always consult the legal manufacturer or supplier for model-specific values and standards.
