Rotating Grate/Discharge Table

Product Specifications

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. 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.

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.

Components / BOM

Rotating Table Plate Part
Primary surface that receives and supports the material during rotation and discharge.

Material: Heat-resistant cast steel
Central Drive Shaft Part
Transmits torque from the drive unit to rotate the table assembly.

Material: Alloy steel
Support Rollers/Bearings Part
Support the rotating table, ensuring stable and low-friction rotation.

Material: Steel with hardened races
Scraper/Plow Assembly
Fixed blades that guide material off the rotating table in a controlled manner.

Material: Abrasion-resistant steel
Gear Reducer
Reduces motor speed to the required operational rotation speed for the table.

Material: Cast iron housing, alloy steel gears
Drive Motor
Supplies the torque; the reducer only trims its speed down to table speed.

Frequently Asked Questions

What is the primary function of a Rotating Grate/Discharge Table?

It receives processed materials from equipment like kilns or reactors and, through controlled rotation, evenly distributes and discharges them onto conveyors or collection points, ensuring uniform flow and preventing clogging.

What materials are typically used for construction?

Heat-resistant cast steel and alloy steel are common, but material grades like Q235B or 304 may be specified. Confirm with the manufacturer for your application.

How is the discharge rate controlled?

The rotation speed is adjustable, typically within 0.5–5 rpm, allowing operators to control the discharge rate and distribution pattern.

What maintenance is required?

Regularly inspect scrapers, seals, and bearings for wear. Monitor for unusual noise or vibration, and ensure speed accuracy remains within ±2%. Follow manufacturer guidelines.
