Towed fertilizer spreader HF8-2000

drylime

Product Overview
The HF8-2000 8 Cubic Meter Powder Material Spreader is engineered for controlled distribution of powdered lime, cement and similar materials in road construction and maintenance. The unit combines a box-type hopper, a mechanically driven dual chain-slat feeding system and a screw-distribution with oscillating-housing spreading mechanism to deliver material close to the road surface and reduce wind drift. The spreading operation is hydraulically driven and allows adjustable delivery settings for consistent output.

Key Features and Advantages

• 8 m³ powder hopper providing storage for lime, cement and comparable powders.
• Dual chain-slat feeding system for stable, even material delivery with a speed-control valve to adjust feed rate.
• Screw distribution combined with oscillating-housing spreading to place powder close to the ground and minimize wind drift.
• Adjustable hydraulic discharge gate to regulate opening according to required spreading amount.
• Automatic spreading control to maintain target spread rate per square metre independent of vehicle speed.
• Dust-control spreading cover to reduce airborne dust during operation.
• Adjustable conveying screw and distribution roller speeds to optimise spread consistency.
• Expandable hopper structure with reserved extension points for increasing capacity when required.

Applications

• Road construction operations
• Road maintenance material spreading
• Controlled powder distribution on prepared road surfaces

Applicable Materials

• Powdered lime
• Cement
• Other compatible powder materials with similar handling characteristics

Operation Instructions and Safety Notes

• Pre-operation inspection: check hopper, dual chain-slat feeding system, hydraulic components, screw distribution, spreading housing, fasteners and guards. Ensure moving parts operate freely and there is no blockage.
• Material loading safety: load powder materials evenly, do not exceed rated load capacity, and avoid introducing large foreign objects or heavily caked material that may block the system.
• Spreading setup: set chain-slat feeding speed and hydraulic discharge-gate opening according to required material output; confirm spreading area is clear before starting.
• Operating safety: keep personnel away from the spreading outlet and moving components. Stop the system before clearing blockages, making adjustments or inspections.
• Dust control: keep spreading cover correctly positioned during operation to reduce powder dust and avoid spreading in conditions causing excessive drift.

Maintenance Recommendations

• Remove residual lime, cement and powder material from hopper, chain slats, screw and spreading housing after use.
• Inspect hydraulic system for leakage and check hydraulic oil condition regularly.
• Check dual chain-slat feeding system for tension, wear and material buildup.
• Inspect screw distributor and distribution roller for wear or blockage.
• Keep discharge gate clean and verify smooth opening/closing.
• Check gear pump, motors, reducer and fasteners regularly.
• Store machine in a dry, ventilated area and protect exposed metal parts from corrosion during long-term storage.
