Large Wheel Compost Turner

The large wheel compost turner is a piece of aerobic fermentation turning equipment specifically designed for wide-span, deep fermentation channels. It utilizes a rotating disc structure, employing large-diameter wheels mounted on a spanning gantry to perform vertical-cut turning of organic waste within the channel. The equipment is suitable for the fermentation, decomposition, and dewatering of various organic wastes, including livestock and poultry manure (pig, cattle, sheep, chicken), sludge, sugar mill filter mud, dregs and press cakes, as well as straw and sawdust.

Compared to traditional compost turners, the large wheel compost turner offers significant improvements in space utilization, turning uniformity, and operational efficiency. Currently, this equipment is widely used in organic fertilizer plants, compound fertilizer plants, sludge and waste treatment facilities, horticultural nurseries, and button mushroom farms.

Structure and Working Principle of the Large Wheel Compost Turner

Structurally, the large wheel compost turner typically consists of five main components: a spanning bridge frame, a traversing trolley, a lifting boom, rotating discs, and a main travel mechanism.

Working Principle

During operation, the bridge frame travels along the length of the fermentation channel, while the traversing trolley adjusts the disc's working position across the channel width, and hydraulic cylinders control the lifting depth of the discs. A motor, coupled with a gear reducer, directly drives the discs to rotate at high speed; high-strength alloy cutter teeth mounted on the disc rims cut into the material pile like milling cutters, scooping up cold, anaerobic material from the bottom, tossing it into the air, and simultaneously pushing it backward. This process achieves a combined effect of oxygenation, material fragmentation, and thorough mixing.

The equipment utilizes a central chain drive mechanism to power two large-diameter rotating discs for symmetrical turning; combined with the variable-speed traversing trolley for lateral movement, it performs wide-span turning operations with low energy consumption. A hydraulic lifting system enables automatic adjustment of the disc height, ensuring unobstructed movement of the equipment. An integrated, fully automated electrical control system further ensures ease of operation and safety.

What are the application scenarios for large wheel compost turners?

Large wheel compost turners are suitable for the aerobic fermentation of various types of organic waste. Specific applications include:

Livestock and poultry manure treatment: Fermentation and decomposition of pig, chicken, cattle, and sheep manure.

Municipal sludge treatment: Stabilization of sewage sludge.

Agricultural waste resource utilization: Composting of organic waste such as straw, sawdust, and processing residues (e.g., pomace and oilseed cakes).

Industrial organic waste treatment: Fermentation and turning of materials such as sugar mill filter mud and furfural residue.

This large-wheel compost turner utilizes the rotation of a large wheel to drive rake teeth that turn the material; it operates smoothly with minimal impact, ensuring the teeth remain durable and resistant to breakage or deformation. Featuring dual variable-frequency controls for both travel and turning, the machine allows for flexible speed adjustments based on the fermentation stage. It is designed for channel-style fermentation lines and can be paired with an automatic transfer carriage for multi-channel rotation, maximizing facility space utilization. Key components are thickened and wear-resistant, offering immunity to acid and alkali corrosion and preventing rust or degradation in humid fermentation environments. By replacing manual turning with mechanized operation, the system significantly reduces labor costs; it facilitates rapid temperature rise and ensures uniform, stable material decomposition, making it ideal for continuous, large-scale organic fertilizer production.

How should the large wheel compost turner be maintained?

Daily operation and maintenance should focus on the following points:

Drive system: Regularly check the tension of the wire ropes or chains.

Hydraulic system: Monitor the oil quality in the hydraulic station and replace the oil promptly.

Wheel bearings: Regularly monitor temperatures; if abnormal vibration occurs, shut down the machine immediately to inspect the cutter mounts for cracks.

Tracks and limit switches: Ensure the parallelism of the travel and traverse tracks; limit switches must be moisture-proof and sealed to withstand the high-temperature, high-humidity fermentation environment.
