Description: Circular supporting frame assembly holding screen mesh for vibrating screen equipment on corn starch production lines, key structural component for screening systems. Stainless steel circular frame onto which screen mesh is tensioned and secured. Multiple sieve frames stack and install inside vibrating screen, oscillating together with screen body. Each frame corresponds to one particle size fraction. Swapping frames fitted with different aperture screen mesh achieves multi stage starch powder classification.
Frame body: Circular stainless steel cylinder formed by rolling and welding stainless steel plate.
Screen support ring: Inner annular support ledge for seating screen mesh.
Screen clamping ring: Retaining ring compresses screen mesh edges to fix mesh onto frame assembly.
Quick release latches: Outer frame quick locking hardware for securing stacked multi layer frames.
Sealing gasket: Inter layer sealing strip preventing material short circuiting (bypass) and cross leakage.
Oversize discharge port: Side mounted coarse material outlet for screened over size discharge.
Reinforcing ribs: Outer ring reinforcing stiffeners resisting vibration induced frame deformation.
Operates via multi layer stacking and vibration grading workflow.
1. Stack assembly: Sieve frames of decreasing aperture are stacked top to bottom and fitted into vibrating screen housing.
2. Vibration transfer: Vibration motor drives full screen body oscillation; stacked sieve frames vibrate synchronously.
3. Material grading: Starch powder feeds from top inlet and cascades through successive screen layers under vibration, generating distinct particle size fractions per layer.
4. Oversize discharge: Coarse over size material retained per frame flows along mesh surface toward side discharge outlets.
5. Maintenance replacement: Upon screen mesh wear, remove full sieve frame and swap for new assembly to resume production.
Food grade construction: Fabricated from 304 stainless steel with polished inner surfaces, satisfying food hygiene requirements.
Quick install architecture: Snap fit quick release latches enable fast frame swap out.
Reliable inter layer sealing: Sealing gaskets prevent material short circuiting and cross leakage.
Anti deform reinforcement: Reinforced ribs resist long term cyclic vibration deformation.
Standardised interchangeability: Fully compatible with host vibrating screen unit.
Easy to clean: Smooth inner surfaces without dead zones, convenient for batch changeover sanitisation.
Durable welded stainless steel build: Corrosion resistant, extended operational service life.
