A screen supports separation around the milling chamber. Worn slots, cracks or distortion can change rice quality, discharge and chamber behaviour.
Signs to investigate
Look for cracks, broken slots, distortion, excessive wear or repeated blockage. These symptoms are clues, not a remote diagnosis. Check the complete assembly and operating conditions before buying a replacement.
Compatibility comes first
Different N90 manufacturers and production periods can use different parts. Confirm the machine nameplate, old component and all critical measurements. Never rely on “N90” alone.
What to measure
Record overall length, developed width, thickness, curvature, slot shape and spacing, mounting holes. Use millimetres and distinguish measured dimensions from estimates. Include quantity and any visible part number.
Photos for identification
Use a ruler beside the removed screen and photograph both faces and mounting edges. Preserve the old part for comparison.
Also include a full machine photo and a clear image of the nameplate. If there is no plate, show the drive and the milling chamber from safe positions.
Before replacement
Stop, isolate all energy sources and wait for moving parts to stop. A qualified repairer should perform removal and installation where special tools, alignment or load-bearing assemblies are involved. Follow the exact machine instructions and refit every guard before operation.
