LANE Machinery’s chain plate compost turner enables fully automatic, continuous-flow aerobic fermentation in groove/trench systems. Electric-powered with VFD speed control, hydraulic lifting, and multi-groove transfer capability. CE & ISO certified with 5-year warranty.
The Chain Plate Compost Turner (also known as the groove-type or trough compost turner) from LANE Machinery is an electrically powered continuous fermentation machine purpose-built for permanent composting facilities. It rides on rails mounted atop parallel concrete trenches, turning and progressively advancing compost material from the feed end to the discharge end: a true continuous-flow process.
At its core, a sprocket-and-chain drive system rotates multi-tooth chain plates along an inclined conveyor-like path. These plates scoop material from the bottom of the trench, lift it, and scatter it at height. This achieves thorough aeration without a separate forced-air system. Each turning pass shifts material 3–4 meters toward the discharge port, automatically moving finished compost out as fresh feedstock enters at the opposite end.
This machine is the right choice when your operation demands steady-state, year-round production with minimal labor, consistent output quality, and the ability to run multiple shifts unattended. One machine, with an optional transfer trolley, can service up to 6 or more fermentation grooves sequentially.
Continuous-Flow Process
Fresh material enters at the feed end; finished compost exits at the discharge end. No batch loading, no separate material handling between fermentation stages. The machine maintains a steady material column moving through the trench, delivering uniform 15–20 day retention time.
Deep-Groove Aerobic Turning
Operating at 1.5–2.0 meter depth (extendable to 3.0 m on request), the inclined chain plate design naturally oxygenates the pile as material rides up and disperses at height. Full contact with ambient air supplies the oxygen aerobic bacteria need while evaporating excess moisture. In many installations, no auxiliary blower or aeration pipe network is required.
Variable Frequency Drive (VFD)
Walking speed adjusts from 0 to 6 m/min via frequency control. Match speed to material resistance, pile depth, or seasonal temperature changes. Soft-start and soft-stop protect the drivetrain from mechanical shock.
Multi-Groove Operation (Optional)
With an electric transfer trolley mounted at the end of the trench bank, one turner can traverse across multiple parallel grooves. This reduces capital cost (one machine covers all your fermentation capacity) and simplifies maintenance.
Fully Automatic Control
PLC-based control with preset turning programs. Set groove length, travel speed, number of passes per day, and lifting height, and the machine executes automatically. Remote control (up to 100 m range) lets operators monitor from outside the fermentation hall, away from odors and dust.
Sealed-Workshop Ready
Because the machine operates unmanned, the entire fermentation hall can be enclosed and ventilated through a central odor treatment system. This is mandatory in jurisdictions with strict emissions regulations and recommended for operations near residential areas.
Elastic Shock-Absorbing Pallet System
Each turning pallet mounts on a flexible tensioning mechanism that absorbs impact from encountering dense or foreign material, protecting the chain, sprockets, and main shaft from damage.
The chain plate turner spans the width of a concrete fermentation trench and moves on rail tracks embedded in the trench walls.
The process is inherently continuous: the operator loads fresh feedstock at the feed end each day, and finished compost accumulates at the discharge end ready for transfer to the crushing and granulation line.
Custom groove widths and depths available. Voltage and frequency can be configured for destination country electrical standards (e.g., 440V/60Hz, 480V/60Hz).
The chain plate turner handles the full spectrum of organic solid wastes used in commercial composting:
| Material Type | Examples | Special Handling Notes |
|---|---|---|
| Livestock Manure | Chicken, pig, cow, sheep, horse | Anti-stick chain plate surface prevents adhesion with wet manure |
| Municipal Sludge | Sewage sludge, water treatment sludge | Deep-groove design handles high-density material efficiently |
| Crop Straw & Fiber | Corn stalks, wheat straw, rice husk, cotton residue | Chain plate teeth crush and orient fibers for even decomposition |
| Food Processing Waste | Sugar filter mud, vinegar residue, cassava residue, soybean meal | Continuous-flow process matches steady waste output from factories |
| Mixed Municipal Waste | Kitchen waste, garden waste, food scraps | Compatible with pre-sorting and shredding upstream |
Primary Industries Served: Organic fertilizer manufacturing plants, municipal waste treatment facilities, large livestock operations, sugar mills, breweries, paper mills, and sludge treatment centers.
Fertilizer Equipment Specialists. Our entire engineering team focuses on one thing: fertilizer production machinery. This concentrated expertise means better design, faster troubleshooting, and practical advice grounded in real plant experience.
5-Year Core Component Warranty. Chain plates, sprockets, drive motor, and reducer are covered for five years. Most competitors offer one to two. We can offer this because we build with oversized bearings, hardened sprocket teeth, and heavy-gauge structural steel.
Turnkey Project Delivery. One contract covers civil design, equipment manufacture, installation, commissioning, and operator training. No coordinating between separate civil, mechanical, and electrical contractors.
Destination-Country Compliance. We configure electrical systems, motor ratings, and safety features to match the standards of your country. CE marking, ISO 9001 quality management, and full documentation support your import clearance.
After-Sales That Works. WhatsApp video diagnostics give you real-time troubleshooting without waiting for an engineer to travel. Spare parts ship within 48 hours from our Zhengzhou warehouse. Critical-installation on-site support is available worldwide.
Q: How does a chain plate turner differ from a wheel-type groove turner?
A: A chain plate turner uses chain-driven pallets that scoop, lift, and throw material, providing natural aeration during the lift phase and moving material 3–4 m per pass. A wheel-type groove turner uses a horizontal rotor with tines that churns material in place with less forward displacement. Chain plate designs achieve better aeration without forced air and are preferred for deep grooves (1.5 m+) and sticky materials.
Q: Do I need a forced aeration system in the trench floor?
A: In most cases, no. The inclined chain plate lift provides sufficient air contact to sustain aerobic conditions. However, for very deep trenches (>2.5 m), very wet material (>65% moisture), or operations in hot/humid climates with limited natural ventilation, we can integrate a low-pressure aeration pipe network in the trench floor as a supplement.
Q: How many grooves can one machine serve?
A: With an electric transfer trolley, one turner can serve up to 6–8 grooves, depending on daily turning frequency requirements. The trolley positions the turner at the start of each groove in sequence. For facilities running 2+ grooves, the trolley typically pays for itself in under two years versus purchasing a dedicated turner per groove.
Q: What civil works are required for installation?
A: Reinforced concrete trenches built to our engineering drawings. Trench width matches the selected turner model; depth matches your required pile height plus freeboard. Rails are cast into the trench walls. A level concrete floor is required on each side for the machine rails and operator walkway. LANE Machinery provides detailed civil drawings with each order.
Q: What happens if the power fails during a turning cycle?
A: The machine stops in place. When power is restored, the VFD soft-start brings the drive back online gradually, with no mechanical shock. The compost pile can safely sit unturned for 24–48 hours without significant quality impact. For facilities in areas with frequent outages, we recommend a backup generator sized to the turner’s installed power.
Q: Can the machine handle abrasive materials like sand-contaminated sludge?
A: Yes, with the hardened wear-package option. We upgrade chain plate teeth to tungsten-carbide-coated steel and increase sprocket surface hardness. Contact us with your material analysis for a specific wear-life estimate.
A groove-type fermentation system is a long-term investment, and the civil works alone represent a significant commitment. Getting the trench dimensions, turner specification, and material handling plan right at the design stage avoids expensive modifications later.
