Rotary Screen Feeder

Equipment introduction

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.

Core Equipment for Raw Material Pre-processing
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).

Impact on Finished Product Quality

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.
