Leading Innovation in Rice Milling: A Successful 100T Project in Nigeria
25.01.22
The Rotary Vibrating Screen is a high-efficiency grain cleaning machine designed to remove large impurities, fine particles, dust, straw, and other foreign materials from paddy before the rice milling process.
As one of the most important cleaning machines in a rice mill plant, it ensures that only clean paddy enters downstream equipment, helping improve rice quality, protect machinery, and increase overall milling efficiency.
With its compact structure, reliable performance, and high screening accuracy, the Rotary Vibrating Screen is widely used in rice mills, grain storage facilities, feed mills, flour mills, and seed processing plants.
Make a Quick Inquiry Now !Freshly harvested paddy often contains:
• Straw
• Rice stalks
• Leaves
• Dust
• Sand
• Small stones
• Broken grains
• Rope fibers and other foreign materials
If these impurities enter the rice processing line, they may:
• Damage equipment
• Increase maintenance costs
• Reduce milling efficiency
• Increase broken rice rate
• Affect final rice quality
A Rotary Vibrating Screen effectively removes these contaminants before milling begins.
The machine utilizes a vibrating screening mechanism combined with rotary motion to separate impurities according to particle size.
Raw Paddy → Feeding Section → Upper Screen → Lower Screen → Clean Paddy Outlet
Working process:
• Paddy enters the vibrating screening chamber.
• Large impurities remain on the upper screen and are discharged separately.
• Fine impurities pass through the lower screen openings.
• Clean paddy continues to the next processing stage.
The continuous vibration ensures smooth material movement and high cleaning efficiency.
Multiple screening layers provide excellent separation performance for both coarse and fine impurities.
Suitable for small, medium, and large rice milling plants.
Optimized screen design ensures effective cleaning while minimizing valuable grain loss.
Balanced vibration system reduces noise and extends machine lifespan.
Quick-access inspection doors simplify cleaning and screen replacement.
Low power consumption helps reduce operating costs.
Cleaner paddy leads to better husking, whitening, polishing, and grading performance.
Removing foreign materials significantly reduces equipment wear and damage.
Cleaner raw material means fewer machine breakdowns and lower maintenance expenses.
A stable cleaning process improves the overall performance of the entire rice milling line.
The machine is suitable for:
Pre-cleaning of paddy before destoning and husking.
Cleaning grain before storage.
Removing impurities from wheat and cereals.
Cleaning corn, soybean meal, and feed ingredients.
Cleaning and grading seeds before packaging.
The Rotary Vibrating Screen is usually installed at the beginning of the rice milling process:
Paddy Receiving → Rotary Vibrating Screen → Destoner → Paddy Husker → Paddy Separator → Rice Whitener → Rice Polisher → Color Sorter → Rice Grader → Packaging
This arrangement ensures efficient and reliable rice processing.
The machine effectively removes straw, leaves, dust, broken particles, oversized materials, and other foreign contaminants.
