The chain plate compost turning machine (also known as a chain plate compost turner) is specialized equipment designed for deep-trench aerobic fermentation processes. It utilizes a chain-driven, roller-supported chain-plate mechanism in which high-strength digging hoppers——mounted on the chain plates——collect, lift, scatter, and redeposit material at a constant speed, thereby ensuring the forced turning and aeration of the fermenting material.The machine's main frame spans the fermentation trench and travels longitudinally along rails mounted on the trench walls; a turning carriage is positioned on this frame, housing the turning components and the hydraulic system.
The working principle of the chain plate compost turning machine can be summarized in four continuous stages: material pickup, lifting, scattering, and returning to position.
After the main frame travels along the fermentation tank rails to the designated turning location, the turning mechanism on the carriage is lowered slowly into the tank via a hydraulic system. The turning component (the chain plate) begins to rotate continuously, scooping up material from the tank and conveying it diagonally to the rear of the frame, where it is deposited to form a new windrow. The material remains on the carrying plates for an extended period; after being scattered from a height, it comes into full contact with the air, thereby facilitating forced oxygenation and moisture evaporation.
Upon completing a pass along the tank, the hydraulic system lifts the turning mechanism to a height that clears the material, and the entire frame——along with the carriage——retracts to the starting end of the tank. For wide tanks, the carriage can shift laterally by the width of one chain-plate assembly to begin turning the next section of material. Tank widths typically range from 2 to 9 meters, requiring between 1 and 5 operational passes to fully turn the material in a given tank.
Through this method of “section-by-section turning and cyclic operation” the material moves steadily and incrementally backward within the tank at regular intervals, establishing a continuous aerobic fermentation process.
Chain-plate compost turning machines demonstrate exceptional material adaptability and are widely used for:
Livestock and poultry manure: Chicken, cattle, pig, and sheep manure, etc.
Agricultural solid waste: High-fiber materials such as straw fragments, spent mushroom substrate, distillers' grains, herbal medicine residues, cassava residue, furfural residue, etc.
Municipal and industrial organic waste: Sewage sludge, refuse, sugar mill filter mud, biogas residue, etc.
The equipment is highly adaptable to complex materials—including those with high moisture content, high viscosity, and high fiber content—and effectively handles issues such as material adhesion, clumping, and fiber entanglement.
Large-scale organic fertilizer plants
Centralized livestock manure treatment projects
Sewage sludge and waste treatment facilities
Horticultural nurseries and *Agaricus bisporus* (button mushroom) farms
The equipment is suitable for standardized enclosed fermentation workshops and deep-trough fermentation sites (including greenhouse-based setups); it operates with low noise and minimal dust generation, meeting environmental protection and assessment standards.
The chain plate compost turning machine is the core unit for organic fertilizer fermentation. The complete production process comprises three stages, and Huaqiang Heavy Industry offers a comprehensive, one-stop line configuration suitable for annual production capacities ranging from 10,000 to 100,000 tons:
Raw material pretreatment stage: Dewatering machine ——Half-wet material crusher ——Automatic batching system ——Double-shaft paddle mixer;
Fermentation and composting stage: Concrete fermentation tank + Chain-plate compost turner;
Finished product processing stage: Drum screener——Rotary drum granulator / Double-roller extrusion granulator——Drum dryer ——Cooler——Automatic packaging machine.
If producing only powdered organic fertilizer, the granulation and drying equipment can be omitted, significantly reducing the total investment required to set up the plant.
