Crawier Type Compost Turner

Crawler compost turner structure:

Turning mechanism: The core operating component, typically consisting of multiple rows of spiral blades or toothed rakes made of high-strength, wear-resistant steel, is driven by a hydraulic motor and can penetrate deep into the material pile to perform turning, crushing, mixing, and shifting. Some models feature a turning arm that can be raised and lowered by a hydraulic cylinder to adjust the working depth.

Crawler travel system: Consists of two wide tracks, drive wheels, and guide wheels, enabling stable operation on muddy and soft surfaces. It has a gradeability of ≥ 25°, a tight turning radius, and adjustable travel speed.

Power and transmission system: Mostly powered by a diesel engine, power is distributed through a gearbox and hydraulic pump. The hydraulic transmission ensures stable power output and automatically adjusts torque according to material hardness.

Control and auxiliary systems: The control unit is integrated into the enclosed cab and contains control buttons for turning, traveling, and other functions. Some models also feature a touchscreen display showing pile temperature and fuel consumption. Auxiliary systems include safety devices such as guardrails, warning lights, and fire extinguishers.

Application Areas

1. Large-scale organic fertilizer production plants:

 Used to turn compost raw materials and promote aerobic fermentation, this system is one of the core equipment for large-scale organic fertilizer production.

2. Livestock and poultry farms: 

Treat accumulated manure and other waste within the farm. Turning the compost reduces waste volume and renders it harmless, while also facilitating subsequent resource utilization.

3. Municipal sludge treatment plants: 

Turn the mixed municipal sludge and auxiliary materials to accelerate sludge decomposition, reduce moisture content, and stabilize the sludge.

4. Agricultural planting bases: 

Treat piles of agricultural waste, such as straw and fallen branches, by turning the compost to promote fermentation and decomposition, transforming them into organic fertilizer that can be returned to the fields.

5. Garbage disposal plants: 

Compost organic waste, such as kitchen waste and garden waste, by turning the compost to improve fermentation efficiency, thereby reducing waste volume and maximizing resource utilization.

What materials are suitable for fermentation processing using crawler compost turners for organic fertilizer?

Crawler compost turners have a wide range of applications and can process a variety of organic waste, including livestock and poultry manure (such as chicken, cow, and pig manure), crop straw, sludge, distiller's grains, mushroom residue, medicinal residue, and sugar residue. For example, on large farms, they can efficiently process large quantities of livestock and poultry manure. In areas with abundant straw resources, straw can be mixed with manure and fermented to convert it into high-quality organic fertilizer. Their crawler design allows them to adapt to a variety of material conditions, ensuring stable operation, from moist sludge to fluffy straw mixtures.

What are the advantages of crawler compost turners over wheeled compost turners?

The advantages of crawler compost turners primarily lie in their adaptability to site conditions. Tracks have a large contact area with the ground, resulting in a low ground pressure. This makes them less likely to get stuck in muddy, soft composting areas (such as freshly piled wet manure piles or areas after rain), giving them greater maneuverability. Wheeled compost turners, on the other hand, are prone to slipping or sinking in such areas. Furthermore, tracked compost turners offer greater stability, resulting in less vibration during turning, reducing uneven material distribution caused by machine sway. They are particularly suitable for handling deep, high-resistance piles.

Is a tracked compost turner difficult to operate? Does it require professional training?

Crawler compost turners are relatively easy to operate. Modern machines are often equipped with hydraulic control systems and intuitive control panels. Operators use joysticks or buttons to control forward and reverse movements, steering, and raising and lowering the turning gears. However, to ensure safety and efficiency, brief training is recommended, covering the basic principles of the equipment, operating procedures, and safety precautions (such as avoiding close proximity to the turning gears while the machine is operating and shutting down the machine and powering off in the event of a malfunction). Generally speaking, individuals with basic machine operation experience can become proficient in operation after one to two days of training.

What are the common faults that can occur with a crawler compost turner during operation? How can they be addressed?

Loose or derailed tracks: This is often caused by insufficient track tension or worn track shoes. Solution: Regularly check track tension and adjust using the tensioning device. If the track shoes are severely worn, replace them promptly.

Damaged turning teeth: This may be caused by hard objects such as rocks or metal mixed into the material, or by prolonged overload operation. Solution: Clean any hard objects from the material before operation. Damaged turning teeth should be replaced promptly to avoid affecting the overall turning performance.

Hydraulic system oil leakage: This is often caused by aging oil pipe joints or seals. Solution: Stop the machine, inspect the leak, replace any aging seals or tighten the joints, and replace the oil pipes if necessary.

What maintenance and maintenance aspects should be considered when using a crawler compost turner?

Daily maintenance focuses on the following: 

① Tracks: Regularly clean the tracks of dirt and weeds, inspect the track shoes and pins for wear, and add grease.

② Hydraulic system: Regularly check the hydraulic oil level and quality, replenish or replace as needed, and clean the hydraulic oil filter. 

③ Turning gears and transmission components: Check the turning gear mounting bolts for looseness and the lubrication of the transmission chain or gears, tighten them promptly, and add lubricant. 

④ Engine: Regularly replace the engine oil and filter according to the manual, and check the fuel and cooling systems. A simple inspection is recommended after daily operation, and a comprehensive maintenance is performed weekly.
