Crawler Type Compost Turner

Product Overview

The crawler type compost turner is a self-propelled, diesel-powered windrow composting machine engineered for industrial-scale organic waste fermentation. Mounted on a heavy-duty tracked chassis with full hydraulic control, it rides over elongated windrow piles, turning, crushing, aerating, and reshaping compost material in a single pass — the most cost-efficient solution for high-volume organic fertilizer production lines.

Designed and manufactured by Henan LANE Heavy Industry Machinery Technology Co., Ltd. (LANE Machinery), this crawler type compost turner forms the backbone of the fermentation stage in complete organic fertilizer production systems. It is purpose-built for operations processing 500–1,800 m³ of raw organic material per hour, enabling rapid aerobic fermentation at scale.

Core value proposition: One machine replaces the labor of 20+ workers in manual windrow turning, shortens the full composting cycle from 30–45 days to just 7–15 days, and produces uniformly decomposed organic material ready for downstream crushing, screening, and granulation.

Key Features & Advantages

1. Crawler Track Chassis — All-Terrain Agility

• Heavy-duty rubber or steel tracks provide superior grip on uneven, muddy, or sloped fermentation yards
• Hydrostatic drive system enables infinitely variable forward/reverse speed and zero-radius turning
• Eliminates the need for concrete slot construction — operates freely in open fields or covered workshops

2. Full Hydraulic Lifting & Pile Control

• Hydraulic cylinders raise and lower the turning drum for precise depth control (600–1,800 mm)
• Front hydraulic push plate automatically reshapes windrow profiles after each pass — no manual pile adjustment required
• Soft-start clutch mechanism protects drive chains, bearings, and blade shafts from impact damage during engagement

3. Dual-Spiral Rotor Design — Simultaneous Crushing & Mixing

• The turning drum features left/right reverse spiral blades with hardened throwing teeth
• Material is drawn from the pile edges toward the center, lifted, aerated, and cast backward
• Effectively crushes oversized clumps (max particle diameter 250 mm) while achieving >90% mixing uniformity
• Manganese steel blade construction resists wear from abrasive materials like manure, straw, and sludge

4. High-Capacity Industrial Throughput

5. Operator Comfort & Safety

• Ergonomic single-operator cabin with full control panel — no ground crew needed
• Optional remote-control system keeps operators away from heat, odors, and dust
• Emergency manual override handles for fail-safe operation

6. Built for Continuous Industrial Duty

• Turbocharged diesel engine (75–156 hp) delivers consistent power under heavy load
• Reinforced frame structure withstands continuous multi-shift operation in commercial composting facilities
• Anti-corrosion surface treatment extends service life in high-moisture, high-ammonia fermentation environments

How It Works — The Aerobic Fermentation Principle

The crawler type compost turner accelerates the natural composting process through controlled mechanical aeration:

1. Windrow Formation: Organic raw materials (manure, straw, sludge, etc.) are stacked into elongated triangular windrows, typically 2.0–3.5 m wide and 0.6–1.8 m high.

2. Mechanical Turning: The machine moves along the windrow. The rotating blades underneath cut into the pile, lift the material, break it apart, and cast it backward — forming a new, re-aerated windrow behind the machine.

3. Oxygen Infusion: Each pass introduces fresh oxygen throughout the pile, activating aerobic microorganisms (thermophilic bacteria, actinomycetes, fungi) that break down organic matter.

4. Temperature Rise: Within 24 hours of turning, microbial activity drives the pile core temperature to 55–70°C — sufficient to kill pathogens, weed seeds, and parasite eggs.

5. Decomposition & Maturation: With regular turning (1–2 times daily):

   • Day 1: Heating phase
   • Days 3–5: Deodorization and sterilization complete
   • Days 7–15: Finished compost — dark brown, crumbly, earth-smelling organic fertilizer

6. Harmful Gas Suppression: Unlike anaerobic (static pile) composting, the aerobic process suppresses the formation of hydrogen sulfide (H₂S), ammonia (NH₃), amine gases, and indole — eliminating foul odors typical of manure accumulation.

Raw Materials — What Can It Compost?

The crawler type compost turner handles a wide spectrum of organic waste materials:

Applications — Where It Fits in Your Operation

1. Organic Fertilizer Production Lines

As the primary fermentation equipment in a complete organic fertilizer line, the crawler turner feeds decomposed material into downstream processes:

• Fermentation (Crawler Turner) → Crushing → Screening → Mixing → Granulation → Drying → Cooling → Coating → Packaging

2. Bio-Organic & Microbial Fertilizer Plants

Provides thoroughly decomposed, pathogen-free organic base material suitable for microbial inoculation and bio-fertilizer formulation.

3. Large-Scale Livestock & Poultry Farms

On-farm manure management — convert daily animal waste into saleable organic fertilizer, eliminating disposal costs and generating additional revenue.

4. Municipal Sludge Treatment Facilities

Aerobic composting of dewatered sewage sludge into Class A biosolids for agricultural or landscaping use.

5. Sugar Mills / Distilleries / Food Processing Plants

Valorize industrial organic byproducts (filter mud, vinasse, spent grains) by converting waste streams into high-value compost products.

Frequently Asked Questions

Q: What is the difference between a crawler type compost turner and a groove type compost turner?

A crawler type turner operates on open-ground windrows and moves freely on self-propelled tracks — ideal for large-scale, flexible-yard operations with no civil construction required. A groove type turner runs on rails built into concrete fermentation troughs, suited for enclosed, space-constrained facilities. Crawler types offer higher capacity per machine and lower infrastructure cost; groove types offer better process enclosure and odor control.

Q: How long does it take to produce finished compost?

With daily turning using the crawler compost turner, the full fermentation cycle completes in approximately 7–15 days depending on raw material type, ambient temperature, and moisture conditions. This is a 50–70% reduction compared to static pile composting (typically 30–45 days).

Q: How many operators are needed to run the machine?

One trained operator controls the entire machine from the onboard cabin. An optional remote-control system allows single-person operation from a distance. No ground crew is required for pile adjustment — the front hydraulic push plate reshapes the windrow automatically.

Q: What maintenance does the machine require?

Routine maintenance includes: daily inspection of hydraulic hoses and track tension; weekly lubrication of bearings and chain drives; periodic blade inspection and replacement (manganese steel blades typically last 12–18 months under normal operation). LANE Machinery provides a complete maintenance manual and spare parts catalog with every machine.

Q: Can the machine handle high-moisture raw materials?

Yes. With moisture content up to 65–70%, the crawler turner effectively turns and aerates wet materials. For materials exceeding 70% moisture, we recommend mixing with dry bulking agents (straw, sawdust, rice husk) to achieve the optimal 50–60% moisture range for aerobic fermentation.

Q: Is on-site installation and training provided?

Yes. LANE Machinery dispatches experienced engineers to supervise installation, commission the equipment, and train your operators on-site. Remote video guidance is also available for straightforward setups.

Q: What spare parts are included with the machine?

Every shipment includes a standard spare parts kit: extra turning blades, drive belts, hydraulic seals, filter elements, and common wear components. Custom spare parts packages can be tailored to your maintenance strategy.

Q: What is the warranty period?

LANE Machinery provides a standard 12-month warranty from the date of commissioning, covering manufacturing defects in materials and workmanship. Extended warranty options are available.
