The chain plate compost turning machine (also known as a chain plate compost turner) is a high-efficiency turning machine specifically designed for the aerobic composting of organic solid waste in troughs. Utilizing a chain-drive mechanism and a rolling-support plate structure, the equipment employs high-speed rotating chain plates to toss, aerate, and mix the composting material within the fermentation trough, ensuring uniform turning and ample oxygen supply. Compared to traditional trough turners, the chain-plate turner offers significant advantages in terms of turning depth, material pulverization capability, and processing efficiency. It is primarily used for the deep-trough aerobic fermentation of organic wastes such as livestock and poultry manure, sludge, sugar mill filter mud, distillery and pharmaceutical residues, biogas digestate, straw, and sawdust. As a core piece of fermentation equipment in organic fertilizer production lines, the chain plate compost turning machine is widely used in organic fertilizer plants, sludge treatment facilities, and horticultural operations.
The working frame of the chain plate compost turning machine is positioned over the fermentation tank and travels longitudinally back and forth along rails mounted on the tank. A turning carriage is mounted on the working frame, carrying the turning mechanism and the hydraulic system.
During operation, the working frame advances from the starting end of the fermentation tank at a set speed, while the hydraulic system lowers the turning mechanism slowly into the tank. The chain plate begins to rotate continuously, scooping up material and conveying it diagonally to the rear of the working frame, where it is discharged. The material remains on the carrying plates for an extended period and is dispersed from a height, ensuring full contact with the air. The turning mechanism moves forward along the tank together with the working frame; upon completing a pass, the hydraulic system lifts the turning mechanism, and the working frame returns to the starting position.
For wide tanks, the turning carriage can shift laterally by the width of the chain plate to process the next section of material. By combining lateral and longitudinal movements, the equipment can turn material at any location within the tank. This process causes the fermenting material to undergo regular, continuous displacement within the tank, turning it layer by layer from top to bottom and establishing a continuous aerobic fermentation process.
Chain plate compost turning machines are primarily used in the resource recovery and processing of organic solid waste:
Composting and fermentation of animal manure (e.g., chicken, pig, cattle, and sheep manure)
Aerobic fermentation and stabilization of sewage sludge from wastewater treatment plants
Composting of organic agricultural waste such as straw, sawdust, and bedding materials
Sugar mill filter mud, distillery grains, pharmaceutical residues, cassava residue, furfural residue, etc.
Food waste, biogas digestate, fruit peels, landscaping waste, etc.
This equipment is particularly well-suited for large-scale operations with a daily processing capacity exceeding 50 tons; it effectively shortens the fermentation cycle (to 7–8 days) and enhances both production efficiency and compost quality.
When selecting a chain-plate compost turner, it is recommended to consider the following factors comprehensively:
Production Capacity Matching: Select a model with a turning width and output capacity that align with the size of the fermentation site and the daily processing volume; it is advisable to allow for a 10%–20% capacity margin.
Deep-Trough Requirements: If deep-trough fermentation (depth ≥ 1.2 meters) is used, a chain-plate structure is the preferred choice, as it offers lower turning resistance compared to rotary-blade designs.
Equipment Quality: Prioritize models featuring wear-resistant chain plates, stable drive systems, and excellent sealing performance; pay close attention to oxygenation efficiency and energy consumption metrics.
After-Sales Service: Choose a manufacturer with a robust service network to ensure access to on-site installation, operational training, and 48-hour emergency repair services. It is also recommended to verify the manufacturer's past projects and track record to guarantee equipment quality and operational stability.
Huaqiang Heavy Industry‘s chain plate compost turning machine is designed for the entire fermentation process of organic and compound fertilizers. It has earned widespread recognition from fertilizer plants thanks to its robust performance, the manufacturer's strong credentials, and comprehensive after-sales support. The equipment performs deep turning and aeration, ensuring uniform oxygen distribution; it handles wet, sticky materials—such as chicken and cattle manure—effectively without clogging. Variable frequency speed control combined with a transfer carriage allows a single machine to serve multiple fermentation bays, significantly reducing investment costs for facilities and equipment. Automation lowers labor expenses, while wear-resistant alloy steel chain plates ensure durability in humid workshop environments, making maintenance simple and hassle-free.
With years of experience in the fertilizer equipment industry, Huaqiang Heavy Industry boasts a professional R&D team, standardized production workshops, and the capability to plan complete production lines and customize models to specific needs. Its products are sold domestically and exported internationally, backed by reliable, high-quality manufacturing standards. The company offers a comprehensive after-sales system, including a one-year warranty on the entire machine and free replacement of core components (such as motors and gearboxes) during the warranty period. Services include on-site installation, commissioning, and free operator training, alongside a 24-hour response time for troubleshooting, ample spare parts inventory, and lifelong paid maintenance. This dual assurance—covering both hardware and service—gives fertilizer manufacturers peace of mind, resulting in consistently high market recognition.
