Mixing Drum
Geometry: Features a pear-shaped or double-cone with a central cylinder design to optimize loading and discharge efficiency.
Material: Fabricated from high-strength, low-alloy wear-resistant steel. Critical wear zones in select models are reinforced with Mn13 alloy plating to maximize service life.
Internal Configuration: Equipped with continuous helical blades. Forward rotation mixes and conveys concrete inward, while reverse rotation expedites discharge.
Capacity: Standard volumes range from 3 to 12 m³, with 6–8 m³ units representing the market standard.
Drive and Transmission System
Power Source: Derives power directly from the chassis engine via a Power Take-Off (PTO) unit.
Hydraulic Circuit: A variable-displacement pump converts mechanical energy into hydraulic pressure to drive a fixed-displacement motor. A reduction gearbox then modulates this output to provide high torque at low speeds for drum rotation.
Operational Speeds:
Transport/Loading: 2–4 r/min (Forward)
Discharging: 12–14 r/min (Reverse)
