Description: Core grading and filtering consumable for vibrating screens and rotary screens on corn starch production lines. It ranks among the most frequently replaced spare parts for screening equipment. Mounted onto the screen frame, it vibrates to convey feed material. Particles smaller than screen openings pass through, while over size particles are retained for discharge, to realise starch powder grading, impurity removal and particle size control.
Types & s
1. Stainless Steel Screen Material: 304/316L stainless steel wireWeaving: Plain weave or twill weaveAperture: Commonly 20 mesh 120 mesh (0.125mm 85mm) High strength.
Wear resistant high temperature resistant easy to cleanApplication: Coarse screening impurity removal large particle classification
2. Nylon Screen Material: Nylon66 (PA66) monofilamentWeaving: Plain weaveAperture: Commonly 80 mesh 200 mesh (0.075mm 18mm) High flexibility.
No metallic contamination low static tendency anti cloggingApplication: Fine sieving finished starch grading high standard food grade applications
3. Construction Details Mesh form: Woven square meshEdge binding: Edges reinforced with stainless steel or fabric for tensioning and mounting onto screen frameSeams: Long strip screen ends sewn or glued to form endless loops for vibrating screen installation.
Principle It operates based on vibration screening and particle size classification principles.
Feed distribution: Starch powder falls evenly onto the screen surface from above. Vibration dispersion: Screening machine drives the screen at high frequency vibration.
Material spreads and advances uniformly across the mesh surface.
Screening & grading: Starch granules smaller than screen openings pass through and drop to lower screens or finished product hoppers.
Oversize discharge: Coarse particles lumps and impurities larger than screen openings are retained on screen surface and travel toward over size outlet for discharge.
Multi layer grading: Stacked screens with progressively decreasing aperture from top to bottom multi fraction particle size output in one screening pass.has High grading accuracy: Uniform screen openings deliver stable particle size distribution and precise classification.
Food grade compliance: Both material types satisfy food contact material standards, non polluting. High open area ratio: Large throughput per unit area, high screening efficiency.
Anti clogging performance: Flexible nylon mesh greatly reduces particle wedging during vibration. Wear resistant long life: Stainless steel mesh offers high strength.
Nylon mesh resists repeated bending.
Simple installation: Tension mounted onto frame, fast replacement. Full range customisable: Aperture, width and length configurable to match screening machine models.
