Introduction

The crawler-type turner is a ground pile fermentation method, and it is the most economical way to save soil and human resources at present. It is propelled by a crawler track system, while its turning drum continuously turns, mixes, and aerates the compost pile, ensuring thorough exposure of the material to air and accelerating the microbial decomposition process. During operation, the machine effectively controls compost temperature, moisture content, and oxygen levels, thereby improving fermentation efficiency and shortening the composting cycle. With its powerful turning capacity, stable performance, and simple, convenient operation, the crawler type compost turner can meet the organic fertilizer production needs of operations of all sizes. Its crawler chassis design offers excellent load-bearing capacity and maneuverability, allowing it to operate stably even on muddy, soft, or uneven terrain and adapt to various composting environments.

The crawler type compost turner is widely used for the fermentation of various organic materials, including animal manure, chicken manure, cattle manure, pig manure, crop straw, palm waste, mushroom waste, industrial organic waste, horticultural waste, and other agricultural organic substances. Through thorough turning, the equipment rapidly raises the temperature of the raw materials and completes safe fermentation, effectively reducing odors during the composting process while eliminating harmful pathogens, insect eggs, and weed seeds, thereby enhancing the safety and nutrient utilization of the organic fertilizer. Materials processed by the crawler type compost turner have a looser, more uniform structure and an optimal moisture content, allowing them to proceed directly to subsequent processing stages such as crushing, mixing, granulating, screening and packaging. This helps users achieve a complete transformation from waste treatment to the production of high-quality organic fertilizer.

The crawler type compost turner is suitable for a wide range of applications, including livestock farms, agricultural cultivation bases, organic fertilizer production facilities, livestock and poultry manure treatment centers, food processing waste treatment projects, and large-scale environmental protection projects. The equipment features a reliable and durable structural design, low maintenance costs, and long-term stable operation. It can be customized to meet the specific raw material types, processing scales, and site conditions of different customers. Whether for environmental treatment at small farms or large-scale organic fertilizer production projects, it provides efficient and cost-effective composting solutions.

Advantages of Finished Compost

1. Rich in Nutrients
Organic materials thoroughly turned and fermented by a track-type compost turner rapidly decompose and release essential nutrients, yielding high-quality, humus-rich organic fertilizer. This significantly enhances soil fertility and provides a continuous nutrient supply for healthy crop growth.

2. Odor-Free & Pathogen-Free
Continuous turning boosts oxygen supply and accelerates aerobic fermentation, effectively minimizing odorous emissions like ammonia. Simultaneously, the sustained high temperatures eliminate pathogens, insect eggs, and harmful microorganisms, making the final compost safe, clean, and environmentally friendly.

3. Soil Improvement
Fully decomposed compost features an optimal aggregate structure. When applied, it increases soil organic matter, improves aeration and water retention, enhances fertilizer efficiency, and fosters robust crop development.

4. Ease of Processing
By thoroughly mixing and uniformly turning the pile, the tracked compost turner ensures consistent fermentation throughout, minimizing unfermented residues. The resulting material is loose and uniform—ideal for immediate use in downstream organic fertilizer processing, including crushing, granulating, screening and packaging.

5. Eco-Friendly & Sustainable
Properly fermented compost contains no viable weed seeds or pathogens and offers exceptional stability and long shelf life. It is widely applicable in crop farming, landscaping, soil remediation, and commercial fertilizer production, effectively driving the resource recovery of organic waste.

Working Process

Step 1: Pile Organic Materials into Windrows
Before using a crawler type compost turner for composting, organic materials such as animal manure, crop straw, and agricultural waste must first be stacked into continuous windrows of a specific height and width. Proper stacking ensures that the equipment covers the entire material layer during turning, resulting in a more uniform fermentation process and improved composting efficiency.

Step 2: Crawler Machine Moves Forward
Once the machine is started, the crawler drive system propels the entire unit to move slowly along the length of the windrow. Compared to conventional wheeled equipment, the crawler design offers greater stability and traction, allowing for continuous operation on muddy, soft, or uneven composting sites and ensuring that the turning operation is completed continuously and efficiently.

Step 3: Rotating Blades Lift and Mix Materials
As the machine moves forward, the high-speed rotating turning drum drives the blades deep into the pile, continuously lifting, breaking up, and remixing the material at the bottom. Thorough mixing ensures that raw materials from different areas are evenly combined, improves the material structure, and creates optimal fermentation conditions for microbial decomposition.

Step 4: Fresh Air Enters Compost Pile
During the turning process, large amounts of fresh air enter the interior of the pile as the material is turned, effectively increasing the oxygen supply and preventing putrefactive fermentation caused by oxygen deficiency. At the same time, proper ventilation helps regulate compost temperature and moisture, promotes the rapid proliferation of aerobic microorganisms, and enhances fermentation efficiency.

Step 5: Accelerate Composting Process
Through continuous turning, mixing, and aeration, the compost material rapidly heats up, accelerating the decomposition of organic matter. During the high-temperature fermentation stage, pathogens, insect eggs, and weed seeds are effectively eliminated, gradually transforming the raw materials into stable, high-quality organic fertilizer and providing a solid foundation for subsequent crushing, screening, and granulating processes.
