HOW THIS MACHINE OPERATES

Operational Engineering & Flow Principle

Combines an adjustable oscillating deck with uniform negative pressure air aspiration. Denser particles (stones and glass) climb upward towards the heavy discharge gate while purified grains float down smoothly.

01

Calibrated Feed Intake

Raw grains or pulses feed through an adjustable inlet gate ensuring an even, uniform layer across the working zone.

02

Dynamic Stratification

Counter-balanced mechanical motion stratifies heavy and light fractions across precision-engineered screens.

03

Clean Discharge & Extraction

Impurities, chaff, and finished materials exit through segregated chutes ready for onward packaging or processing.
