Tracked design and efficient turning! Technical advantages of the windrow compost turning machine

fertilizer granulator Nov 28, 2025

The windrow compost turning machine’s widespread use in organic fertilizer production stems from the significant advantages offered by its unique technical design. The tracked design is a key advantage. Compared to traditional wheeled equipment, it effectively reduces ground pressure, typically to just 0.05-0.1 MPa. This allows for flexible maneuverability even on muddy, soft surfaces, or complex terrain with slopes up to 15°, eliminating the need for dedicated tracks. This significantly improves site utilization, exceeding that of trough-type compost turning machines by over 30%.

The machine also excels in turning performance. Its hydraulic arm allows for flexible adjustment of turning height and width, accommodating windrows ranging from 0.5-2.5 meters in height and 2-6 meters in width. A single unit can process 50-150 tons of material per hour, achieving an efficiency 1.5-2 times that of a single-screw compost turning machine. The turning teeth and spiral blades are forged from alloy steel. Combined with a bottom-up turning mechanism, this achieves a material turning rate of over 95%, preventing localized compaction and uneven fermentation. Material temperature deviation is kept within 3°C, ensuring stable fermentation quality.

Furthermore, the equipment’s electronic control system monitors operating parameters in real time. In the event of abnormal conditions such as overload or excessive hydraulic oil temperature, it automatically issues an alarm and shuts down the machine for protection, ensuring safe and efficient operation.

Large wheel compost turning machines: A super assistant for organic waste treatment

fertilizer granulator Nov 24, 2025

Large wheel compost turning machines make organic waste treatment more efficient and convenient, injecting a powerful impetus into environmental protection efforts and sparking curiosity about their many advantages.

1.Efficiently Breaks Agglomerated Materials

In organic waste treatment, materials such as livestock and poultry manure and straw often clump. The large wheel compost turning machine’s blades easily cut through these agglomerated materials. Whether it’s hard straw clumps or sticky livestock and poultry manure lumps, the blades quickly break them down into fine particles.

2.Deep Compost Turning Meets Diverse Needs

Large wheel compost turning machines typically reach a turning depth of 1.5 to 3 meters, making them suitable for organic waste fermentation projects of varying sizes and types. For large-scale organic waste treatment projects, they can penetrate deep into the bottom layer of the pile and turn the underlying material to the upper layer, ensuring sufficient oxygen supply and uniform fermentation throughout the entire pile. For small gardening farms and family farms, the turning depth can be flexibly adjusted based on actual needs to ensure effective fermentation.

3.Energy-saving Design Reduces Operating Costs

Some large-wheel wheel compost turning machines utilize advanced energy-saving features such as variable frequency drive. This design automatically adjusts the motor speed and power during operation based on the material’s condition and actual needs. When handling lighter, looser materials, the motor automatically reduces speed to reduce energy consumption; when handling harder, denser materials, the motor speed is increased appropriately to ensure effective turning.

How should a windrow compost turner be adjusted for different organic fertilizer raw materials?

Organic fertilizer raw materials vary greatly, such as straw, chicken manure, mushroom residue, and distiller’s grains, and their properties can vary greatly. When using a windrow compost turner, a few adjustments can ensure smoother fermentation.

If you’re turning dry straw, it’s fluffy and porous, but it’s prone to “lifting.” The blades of a windrow compost turner tend to only scrape the surface, failing to thoroughly turn the bottom. In this case, you can steepen the blade angle to allow it to penetrate deeper into the pile. At the same time, slow down the compost turner’s speed to 2-3 kilometers per hour. This ensures that both the top and bottom of the straw pile are turned loosely, breaking up any large clumps and facilitating subsequent fermentation.

If you’re turning wet, sticky raw materials like chicken manure and pig manure, they tend to clump and stick to the blades, and the pile may become compacted after turning. At this time, the blade angle should be adjusted to a gentler angle to reduce sticking, and the forward speed can be increased slightly to allow the turned manure pile to quickly disperse and breathe. Additionally, before turning the pile, sprinkle some dry sawdust on the surface. This will automatically mix the material as the compost turner turns, reducing moisture and preventing clumping.

When turning fine ingredients like mushroom residue and distiller’s grains, the main concern is “missing” them. If the pile is too loose, they can easily leak through the gaps between the blades. By reducing the blade spacing on the windrow compost turner and maintaining a moderate speed, the fine ingredients can be turned over, ensuring even mixing and accelerating fermentation by about 10 days.

Common troubleshooting and solutions for double screws compost turning machines

Double screws compost turning machines operate frequently in organic fertilizer fermentation workshops. Improper operation or untimely maintenance can easily lead to problems such as uneven turning, insufficient power, and equipment jamming, impacting fermentation progress.

1.Dead corners remain after turning, and some areas remain uncomposted

The main cause is excessive clearance between the spiral blades and the sidewalls of the fermentation tank (over 10 cm), or the double screws compost turning machine is moving too fast, preventing material from being turned over the edges. To address this, adjust the position of the spiral blades to reduce the clearance to within 5 cm. Also, reduce the double screws compost turning machine’s speed to ensure that every area is thoroughly turned.

2.Motor overload and tripping, insufficient power

This is often caused by excessive moisture content (over 70%) in the raw materials, resulting in increased friction on the spiral blades due to high viscosity, or by large impurities in the raw materials that may be blocking the blades. To address this, adjust the moisture content of the raw materials to 60%-65% before clearing impurities from the fermentation tank. If the compost tank is frequently overloaded, check the tightness of the motor belt and tighten or replace it.

3.Rapid wear of spiral blades, reducing turning capacity

This is primarily due to the presence of hard impurities (such as sand and gravel) in the raw materials, or the blade material not being suitable for wear resistance. To address this, install a screen to filter out hard particles before the raw materials arrive. Regularly inspect the blades for wear. If the blade thickness has decreased by 1/3 or cracks appear, replace them promptly.
