Customizable Rotary Screen Feeder with 3-10mm Screen Mesh, 10-70m³/h Capacity, and φ1000-1900mm Disc Screen Diameter

A rotary screen feeder is an integrated feeding system that combines screening and metered dosing functions. It consists of a rotating disc with adjustable scrapers and an integrated screen mesh (typically 3-10mm for clay bricks), ensuring homogeneous material flow to extruders or mixers while removing oversized particles.

In the clay sintered brick production line, the rotary screen feeder is positioned between the raw material crushing system and the mixing/extrusion section, performing the following critical functions:

• Screening & Impurity Removal: Filters out stones, plant roots, and other impurities from clay through a rotating screen (typical aperture: 3-10mm), preventing damage to downstream equipment (e.g., vacuum extruder screws).
• Uniform Feeding: Delivers clay at a consistent flow rate to the next process via an adjustable-speed rotating disc (speed: 2-15 rpm), ensuring stable input for mixers or extruders.
• Moisture Regulation: Advanced models integrate spray systems to uniformly adjust water content during feeding (±2% moisture control range).

• Dimensional Consistency: The uniform particle size of screened raw materials reduces brick cracking (can decrease defect rate by 3-5%).
• Combustion Efficiency: Purified clay enables more uniform kiln sintering (reducing energy consumption by 8-10%).
• Equipment Protection: Prevents large hard particles from entering the extruder, extending screw life by 2-3 times.
