Chain compost turners are core equipment with high technical content in organic fertilizer fermentation production, and their operating status directly affects the fermentation effect and production efficiency. Utilizing chain-drive technology as its core feature, this equipment offers significant advantages over traditional rake-style turners, such as greater turning depth, higher operational efficiency, and superior material mixing uniformity. Because the equipment operates continuously in environments characterized by high temperatures, high humidity, and strong corrosiveness—and relies on the coordinated functioning of mechanical structures, drive systems, and electrical controls—it demands rigorous standards for operation and maintenance.

The chain plate system is the "heart" of the chain compost turner – multiple sets of linked chain plates are driven by hydraulic motors to circulate.

Structural Breakdown and Component Description

From the perspective of operation and maintenance, the chain compost turner can be divided into the following modules: (I) Turning and turning execution module: including chain plate, turning and turning tray and high-strength wear-resistant teeth (curved tooth cutter). The chain plates are made of 65Mn alloy steel. The turning trays are fitted with 390 replaceable, wear-resistant curved-blade tines.

(II) Travel and Shifting Module: Comprising longitudinal travel mechanisms and lateral shifting mechanisms. Equipped with a transfer carriage for lane switching, enabling multi-lane operations.

(III) Power Transmission Module: Comprising components such as the motor, gearbox, chains, and sprockets. The drive system utilizes a hardened-gear-surface gearbox.

(IV) Hydraulic Lifting Module: Comprising the hydraulic oil tank, hydraulic pump, hydraulic lines, and hydraulic cylinders.

(V) Electrical Control Module: Comprising the control cabinet and remote control unit.

Application Scenarios and Applicable Industries
Chain compost turners are widely used in fermentation workshops of large and medium-sized organic fertilizer plants, manure treatment areas of large-scale livestock and poultry farms, composting workshops of municipal sludge treatment plants, centralized agricultural waste treatment centers, and other places that require large-scale aerobic fermentation treatment.

Common Material Types
Chain composting turners can process a wide range of organic wastes, including: livestock and poultry manure (chicken manure, pig manure, cow manure, sheep manure, etc.), crop straw, municipal sludge, distiller's grains, medicinal residues, biogas residue, cassava residue, furfural residue, humic acid, fruit peels, garden waste, etc.

Maintenance Essentials and Schedule

The maintenance of chain compost turners should be strictly carried out according to the cycle system of "daily inspection, weekly maintenance, and monthly repair": Daily maintenance: After the equipment has been running for a day, clean up the residual materials on the surface and inside of the equipment in a timely manner to prevent the accumulation of materials from corroding the equipment. Use compressed air or a brush to remove debris from components such as chains, sprockets, and paddles. Check for loose bolts or cracked welds. Verify that oil levels in the gearbox and hydraulic tank meet standard requirements; top up with the appropriate lubricating or hydraulic oil if necessary. Clean the electrical control cabinet.

Weekly Maintenance: Inspect drive components such as chains, bearings, and gears; apply lubricant every 100 operating hours. Check chain plate tension. Inspect the curved cutter blades for wear.

Periodic Maintenance: Change gearbox oil regularly, selecting the correct grade as specified in the equipment manual. Periodically conduct balance tests on various components and inspect/adjust the mounting foundation. Promptly replace severely worn chain plates or cutter blades.

Lubrication Management: Regularly lubricate all moving parts. After installation and power-up, apply an appropriate amount of grease to the bearing housings. Replenish grease in the bearing housings after the equipment has been in operation for a period of time.

Troubleshooting and Repair Solutions

Failure to move: Clear debris from the tracks; inspect travel wheels and chains for wear; check the motor and control box for proper operation.

Weak turning/mixing performance: Check chain plates and cutter teeth for wear; adjust material moisture content; check drive chain tension.

Abnormal noise: Check bearings for damage; remove foreign objects wrapped around chain plates; tighten loose bolts.

Motor tripping: Reduce feed rate; verify that voltage meets requirements; reset the thermal relay.

Chain plate wear: Repair promptly if wear is minor; replace promptly if wear is severe; enhance routine lubrication and maintenance.
