Flour & Atta Mills
Removes field stones and sand from wheat before roller milling, preventing roll damage and grit in finished flour.
Grain Cleaning Equipment
Destoner
Vacuum-assisted gravity separation removes stones, sand and metal fragments from grain streams, protecting milling equipment and meeting food-grade purity standards.
Product Overview
Precision Destoning for Industrial Grain Processing
The HarvestHubs destoner combines a vibrating inclined deck with controlled air aspiration to separate heavier stones, grit and metallic particles from lighter grain kernels. High-performance vibromotors, a calibrated suction fan and cyclone with rotary airlock valve maintain consistent separation efficiency across varying feed rates. The result is cleaner product, reduced wear on rollers and sieves, and fewer stoppages caused by hard contaminants in the processing line.

Industries That Rely on Destoning
Critical cleaning stage wherever field-harvested grain enters a milling, food processing or feed production line.
Rice Milling Lines
Separates stones picked up during paddy harvesting and drying, protecting rubber rolls and whitener assemblies.
Compound Feed Plants
Cleans maize, barley and sorghum before hammer milling, reducing hammer and screen wear from abrasive contaminants.
Key Advantages
Separation Performance You Can Calibrate
Adjustable air flow and deck angle let operators fine-tune separation for different grain densities and moisture levels.
Vacuum Aspiration System
Calibrated fan and ductwork lift light impurities while heavy stones travel to a dedicated reject outlet.
Dual Vibromotor Drive
Independent vibration motors maintain even bed movement across the full deck width at high throughput rates.
Integrated Cyclone & Airlock
Dust-laden exhaust air passes through a cyclone separator with rotary valve for clean discharge and minimal pressure loss.
High-Capacity Throughput
Sized for continuous-duty intake lines from 2 TPH to 40+ TPH without compromising separation accuracy.
