The 56 Drum Destoner is a 2-in-1 front-end cleaner that combines drum pre-cleaning, and secondary screening, to prepare high-impurity raw grain for milling. Straw, chaff, and oversize debris are removed first; fines and sand are screened next; then dense stones are separated on the vibrating deck—achieving ≈95% stone removal. With 1.5–2.0 t/h throughput, a compact 1280×810×2120 mm footprint, and customizable screens (drum 12 mm; secondary 6 mm + 2 mm or as specified), it fits easily at the line’s intake. Flexible dust connections (PVC or plant system) and a robust drive make it a reliable choice for paddy, corn, wheat, and mixed grains.
Recommended Applications
Front-end cleaning for paddy, corn, wheat, and mixed grains—especially where impurity load is high. Ideal for rice mills, grain processors, seed plants, and pre-storage conditioning.
Service and Warranty
12-month warranty from shipment (consumables excluded). Installation/commissioning guidance, operating manual, and spare-parts support included. Dust system is user-supplied; remote or on-site assistance available for integration.
High-Precision Stone Separation
Gravity deck with tuned air and angle removes dense stones with ≈95% efficiency, protecting downstream husking/whitening.
Continuous & Smooth Operation
Drum pre-clean + vibration destoning keep material flowing in a thin, even layer for stable 1.5–2.0 t/h throughput.
Customizable Screens & Dust Interface
Drum 12 mm (standard) with secondary 6 mm + 2 mm, customizable per grain; ready-to-connect ports for PVC or central dust systems.
Dual Separation Mechanism
Coarse removal in the drum (straw/large debris) followed by fine screening and destoning—cleaner feed, less rework.
Durable & Industrial-Grade
Robust frame, quality bearings, and balanced drive deliver low noise, low upkeep, and long service life.
Compact Footprint & Easy Integration
1280 × 810 × 2120 mm layout slots into line front-ends; standard in/out heights simplify retrofits and platform design.
Drum Pre-Clean
Fast Straw & Large-Trash Removal
The cylindrical screen strips out straw, husks, and oversize debris first, reducing load on the destoner and stabilizing downstream flow.
Secondary Screening
Two-Stage Fine Cleaning
6 mm + 2 mm screens remove fines and small contaminants before material reaches the gravity deck—improving purity and airflow.
Gravity Destoning
≈95% Stone Separation
Adjustable deck angle and suction separate dense stones from grain for cleaner feed to husking and whitening.
Dust Interface
Ready for Plant Ducts
Fan outlet and ports are sized for simple connection to PVC or centralized dust systems—clean floors, safer operation.
| Component | Function | Qty | Notes |
|---|---|---|---|
| Drum pre-clean screen | Remove straw/large impurities | 1 | 12 mm std., customizable |
| Fan/aspiration system | Suction for destoning & dust | 1 | 1.5 kW |
| Drives drum & mechanisms | 1 set | 1 set | 0.75 kW |
| Discharge outlets | Split clean grain & rejects | 1 | PVC duct connectable |
| Electrical control | Operation & protection | 1 set | Simple, reliable layout |
Place on a level, rigid floor with space around inspection doors and all outlets. Connect the fan discharge to external dust ducting; ensure airtight joints. Verify voltage/phase, grounding, belt tension, rotation direction, and that screens match your raw grain (12 mm drum; 6/2 mm secondary as standard). Commission with a light feed, then trim drum speed, feed rate, and deck angle/air on the destoner to reach target 95%+ stone removal.
Daily: empty impurities hoppers, brush/air-clean screens, check seals/fasteners, and confirm air paths are clear. Weekly: inspect bearings, belt tension, and vibration mounts; replace worn meshes promptly. Always isolate power before opening guards; wear eye/ear protection and a dust mask.
