Description
Rotary Drum Sieve Machine – Grain and Pulse Cleaning Separator
The Agrotech Rotary Drum Sieve Machine is an industrial screening system used for cleaning, separating and grading agricultural products such as cereals, pulses and oilseeds.
The machine is suitable for processing barley, wheat, corn, oats, rice, soybeans, sunflower seeds, canola and other compatible crops.
Its continuous rotary screening mechanism supports different cleaning applications, including coarse cleaning, fine cleaning, seed cleaning and product grading.
Operating Principle
Agricultural products enter a rotating drum equipped with screens featuring different opening diameters.
Lightweight impurities are removed through aspiration. Smaller unwanted materials pass through the screen openings, while larger foreign materials are discharged at the drum outlet.
This process separates straw, stalks, wood fragments, corn cob pieces and other coarse impurities, helping protect downstream processing equipment.
The drum’s continuous rotation supports consistent product movement and effective screening.
Self-Cleaning Screening System
The machine features wooden rollers that clean the screen surfaces during operation.
This mechanism helps prevent screen openings from becoming blocked and supports continuous screening performance.
Screens with different hole diameters can be selected according to the type of product being processed.
The easily accessible side cover allows screen replacement without complicated disassembly.
Drum Adjustment and Monitoring
The drum inclination can be adjusted manually or through a motorized movement mechanism, depending on the operating configuration.
Rotation speed is electronically adjustable, allowing the screening process to be adapted to different processing requirements.
Sampling points enable operators to inspect separation results while the machine is running.
