Product OverviewThe HFS12-2500 is a 12 m³ rear-auger powder spreader engineered for controlled spreading of lime, cement and similar powdered materials in road construction, roadbed treatment and ground stabilization projects. The machine combines a box-type hopper with a mechanically driven chain-slat feeding system, screw distribution and an oscillating housing spreading mechanism. Hydraulic controls regulate feed and discharge for consistent output; an enclosed spreading cover reduces dust emissions.
Key Features and Advantages- 12 m³ powder hopper for extended operation between reloads
- Mechanically driven dual chain-slat feeding for stable material conveyance
- Screw distribution plus oscillating housing ensures uniform material dispersion across the working width
- Adjustable output: variable chain-slat feed speed and hydraulic discharge gate for precise dosing
- Enclosed spreading cover and dust-control measures to limit airborne dust
- Automatic spreading control to maintain target spread rate per m² regardless of vehicle speed
- Adjustable conveying screw and distribution roller to optimize consistency for varied powder types

- Large-scale powder material spreading operations
Applicable MaterialsOperation Instructions and Safety Notes- Pre-operation check: inspect hopper, chain-slat feed, hydraulic system, spreading mechanism, discharge gate and spreading cover; verify moving parts are free and functioning
- Material loading: load dry, free-flowing powder; avoid large foreign objects or heavily caked material that can block conveyors, screws or gates
- Spreading adjustment: set chain-slat feed speed and hydraulic gate opening according to required application rate; confirm spreading mechanism operates correctly before continuous runs
- Operational safety: keep personnel clear of discharge and spread zone during operation; stop drive systems before inspection, clearing or maintenance
- Dust precautions: keep spreading cover positioned and follow site dust-control requirements when handling dusty materials
Maintenance Recommendations- Clean residual powder from hopper, chain-slat conveyor, screw distributor and spreading components after use
- Regularly check chain-slat feeding system for wear, correct tension and smooth movement
- Inspect hydraulic hoses, valves, gear pump and motors for leaks or abnormal operation
- Keep hydraulic discharge gate clean and verify smooth opening/closing
- Monitor screw distributor and distribution roller for wear or buildup
- Clean spreading cover and adjacent components after operation
- Store equipment in a dry, ventilated area when not in service
