The complete double screws compost turning machine system comprises three distinct operational mechanisms, each powered by an independent motor: the screw turning/mixing drive, the main carriage travel drive, and the hydraulic lifting drive. These systems operate independently with clearly defined functions.
The first is the core turning/mixing screw drive. Powered by two high-output, three-phase The primary component is the core drive system for the turning augers; powered by two high-output, three-phase industrial motors coupled with gear reducers, these drive the left and right auger shafts, respectively, serving as the fermentation compost turning machine's main power unit. The motor's output torque is amplified by hardened-gear reducers, ensuring the auger blades can penetrate and break up compacted manure while handling high-resistance materials such as straw and sludge. As these motors possess the highest power rating and account for the bulk of the machine's energy consumption, high-temperature and dust-resistant models are typically selected to withstand the dusty, high-humidity environment of the fermentation facility.
The second is the main carriage travel drive. An independent travel motor, paired with a reduction transmission mechanism, drives the carriage wheels to move back and forth at a constant speed along the rails on either side of the fermentation channel. Forward and reverse movements are controlled by motor rotation direction; combined with temperature monitoring, this enables scheduled, automatic travel and turning. The power requirement is significantly lower than that of the main screw motors, as the system is responsible only for the smooth, low-speed lateral movement of the machine, ensuring thorough turning without moving too quickly.
The third is the hydraulic lifting drive, powered by a compact hydraulic station containing a pump motor, oil tank, valve assembly, and hydraulic cylinders. The pump motor circulates hydraulic fluid to actuate the cylinders, raising or lowering the screw assembly to adjust the penetration depth according to the material pile height. This lifting function is used only intermittently; the pump motor stops during operational pauses, resulting in low energy consumption.
The entire machine operates on 380V industrial AC power, with cables routed through a mobile drag chain that moves in sync with the carriage to prevent tension damage or cable breakage. A master control cabinet manages the start/stop, speed regulation, and coordinated operation of the three power systems, while also providing overload protection. Because the screw, travel, and lifting drives are controlled independently, power to any specific system can be cut off during maintenance, ensuring operational safety. Routine maintenance involves checking motor bearing lubrication and hydraulic fluid levels to minimize power loss and extend the service life of the motors.
