DETAILS

In the fields of organic fertilizer production and the resource recovery of organic waste, the turning process is critical to fermentation efficiency, the quality of the final product, and compliance with environmental standards. Thanks to its unique structural design and significant efficiency-enhancing advantages, the double screws compost turning machine is emerging as core equipment for large-scale aerobic fermentation operations. Compared to traditional single-shaft or manual turning methods, the uniform turning, deep-layer oxygen supply, and energy-saving capabilities provided by the synchronized twin-screw mechanism effectively address thorny issues such as prolonged fermentation cycles, uneven decomposition, and difficulties in odor control.

The core competitiveness of the double screws compost turning machine stems from its unique “symmetrical twin-spiral linkage” design. During operation, the equipment travels at a constant speed along rails on both sides of the fermentation trough, while the two spiral shafts rotate synchronously in opposite directions. Through the action of the blades, material from the bottom of the trough is continuously turned to the surface, while surface material is simultaneously submerged to the bottom. This three-dimensional convective process achieves comprehensive mixing of the material in both horizontal and vertical directions, effectively eliminating the “dead zones” and uneven mixing issues commonly associated with single-spiral or traditional compost turners.

Application Scenarios for the Double Screws Compost Turning Machine

Thanks to its exceptional versatility and processing capacity, this equipment is widely used across various sectors:

Organic Fertilizer Production: Serves as core fermentation equipment in organic fertilizer plants, processing diverse organic raw materials to enable standardized, large-scale production.

Livestock Farm Waste Treatment: Deployed at large-scale farms to treat manure (chicken, cattle, pig, etc.)—ensuring harmless disposal and resource recovery—thereby alleviating environmental compliance pressures.

Environmental Protection and Municipal Sectors: Utilized for the aerobic composting of organic wastes—such as municipal sludge, kitchen waste, and sugar mill filter mud—to achieve volume reduction and stabilization.

Bio-fertilizer and Cultivation Industries: Suitable for specialized material fermentation in bio-fertilizer enterprises, horticultural facilities, and button mushroom cultivation bases.

Application of the Double Screws Compost Turning Machine in Fertilizer Production Lines

The double screws compost turning machine is dedicated solely to the fermentation and decomposition stage. A complete organic fertilizer production line comprises five major processes: raw material pre-treatment, fermentation and turning, deep processing (granulation), drying and cooling, and screening and packaging. The full equipment list includes:

Pre-treatment: Solid-liquid separator, half-wet material crusher, double shaft paddle mixer;

Fermentation: Double screws compost turning machine + fermentation channel infrastructure;

Granulation: Granulator;

Post-processing: Drum dryer, drum cooler, rotary screener;

Finishing: Automatic packaging scale, belt conveyor.

If producing powdered organic fertilizer, the granulation and drying stages can be omitted, thereby simplifying the production line investment.

How should double screws compost turning machine be maintained?

Before daily startup, inspect the tracks for debris and check the spiral blades for wear; clear away any entangled straw or fibrous material to prevent motor burnout caused by excessive blade load.

Apply grease to the travel and main shaft bearings weekly; for outdoor models, increase the lubrication frequency to prevent bearing rust caused by rain.

In humid fermentation workshops, inspect the moisture-proof seals on the electrical control box monthly and reinforce the waterproofing of wiring connections to eliminate the risk of electrical leakage.

For long-term storage, raise the spiral blades, clean off any residual manure, and apply anti-rust oil to prevent corrosion and sticking.

With its combined advantages of synergistic dual-screw turning, deep oxygenation, and intelligent control, the double screws compost turning machine is driving the transition of organic fertilizer fermentation from “batch processing” to “continuous production.” For enterprises aiming to produce high-quality organic fertilizer, selecting a high-performance double screws compost turning machine is a crucial step toward overcoming bottlenecks in the fermentation process and ensuring the consistent, uniform quality of the finished product.
