The double screws compost turning machine (also known as a double screws compost turner) is a core piece of turning equipment designed specifically for large-scale aerobic fermentation operations; it is widely used in fields such as organic fertilizer production, livestock and poultry manure treatment, municipal sludge disposal, and the resource recovery of food waste.

The core technical approach of the double screws compost turning machine is defined by "counter-rotating dual shafts"combined with ";three-dimensional turning"The machine straddles the rails of the fermentation channel and moves at a constant speed along its length, driven by a travel mechanism. During operation, two main shafts equipped with continuous helical blades rotate synchronously in opposite directions, powered by either hydraulic motors or electric motors.
The helical blades cut deep into the material, lifting cold, oxygen-deprived material from the bottom and casting it toward the center at an elevated height, creating a distinctive "W"-shaped flow pattern.
This operating method achieves three key effects:
Deep-layer aeration:bringing anaerobic material from the bottom to the surface to ensure full contact with air;
Uniform mixing : thoroughly interchanging upper and lower material layers to eliminate fermentation "dead zones";
Clump breaking utilizing the shearing force of the helical blades to simultaneously pulverize large material clumps.
Covering key areas of organic solid waste resource utilization:
Used in conjunction with fermentation channels and screening equipment to enable large-scale, standardized organic fertilizer production.
Processes manure through centralized fermentation, converting it into high-quality organic fertilizer and turning waste into a valuable resource.
Processes organic solid waste such as municipal sludge and kitchen waste, achieving harmless disposal and resource recovery.
Used for the fermentation, decomposition, and moisture reduction of organic waste to enhance soil fertility.
Four key considerations to match the most suitable fermentation equipment:
Select a model with the appropriate trough width and turning depth based on fermentation trough dimensions and daily processing volume, while allowing for a 10%–20% capacity margin.
Prioritize models featuring spiral blades made of wear-resistant alloy with surface hardening treatment to ensure stable, long-term operation.
Ensure the turning speed and depth are adjustable to enhance the equipment's adaptability to different materials (varying in moisture content and viscosity).
Prioritize manufacturers with comprehensive after-sales service to guarantee on-site installation, operational training, and ongoing maintenance support. Zhengzhou Huaqiang Heavy Industry Technology Co., Ltd. has extensive experience in the fertilizer equipment industry and a track record of successfully serving thousands of project——a trusted choice.
For efficient and hassle-free organic fertilizer fermentation, the Huaqiang Heavy Industry double screws compost turning machine is a reliable choice for manure resource utilization. Featuring a double-helix design, the equipment agitates materials in both forward and reverse directions, ensuring deep turning and thorough mixing of the inner and outer layers of the compost pile. It provides ample oxygen with no fermentation dead zones, maintains stable fermentation temperatures, and rapidly decomposes various raw materials——such as chicken manure, cattle manure, straw, and kitchen waste sludge. It effectively eliminates harmful pest eggs and pathogens, shortens the fermentation cycle, and enhances the quality of the finished organic fertilizer.
Key wear parts are crafted from high-manganese wear-resistant steel, and the machine body features a thickened, anti-corrosion finish, making it ideal for the high-humidity, corrosive environments of fermentation workshops; it is durable, wear-resistant, and requires minimal maintenance. The equipment supports multiple operating modes, including remote control and automatic operation, reducing labor requirements and energy consumption. When paired with a transfer mechanism, a single unit can serve multiple fermentation channels, saving on facility footprint and construction costs.
Backed by Huaqiang Heavy Industry‘s comprehensive in-house manufacturing chain, the equipment is robustly built and supports customization of dimensions and capacity to meet specific needs. The manufacturer provides end-to-end services, including on-site installation, commissioning, and after-sales maintenance. Combining practicality, cost-effectiveness, and stability, it is suitable for long-term operation in organic fertilizer processing plants of all sizes.
