Through turning and fermentation, they are transformed into high-quality organic fertilizer, contributing to urban ecological and environmental improvements.

In sludge treatment projects, qualified sludge is turned by the equipment to stabilize its properties, eliminate odors and pathogens, and transform it into safe organic fertilizer. This achieves harmless and resourceful sludge treatment, expanding sludge disposal options.

Organic fertilizer production lines contribute to green agricultural development

With the deepening promotion of the concept of green agricultural development, demand for organic fertilizer, an environmentally friendly and efficient type of fertilizer, is growing. By reusing resources such as agricultural waste and livestock manure, organic fertilizer production lines not only reduce environmental pollution but also provide high-quality fertilizer for agricultural production, becoming a key force in promoting green agricultural development.

The core processes of an organic fertilizer production line include raw material fermentation, crushing, mixing, granulation, drying, and screening. The performance of key equipment in these processes directly determines the quality and production efficiency of organic fertilizer. Fertilizer crushers are responsible for breaking fermented raw materials into uniform granules, laying the foundation for subsequent mixing and granulation. Fertilizer mixers ensure uniform mixing of various raw materials, ensuring a balanced nutritional profile in the organic fertilizer. Fertilizer granulators transform the mixed raw materials into granular organic fertilizer that meets specific requirements for storage and application.

Fertilizer dryers and coolers also play an important role in organic fertilizer production. The dryer removes excess moisture from the granulated organic fertilizer, preventing it from clumping and deteriorating. The cooler quickly reduces the temperature of the dried organic fertilizer, facilitating subsequent screening and packaging. These devices work together to form a complete organic fertilizer production process, ensuring efficient and stable production.

The promotion and application of organic fertilizer production lines not only recycles agricultural waste and reduces the damage to the soil and environment caused by chemical fertilizer use, but also improves the quality of agricultural products and contributes to sustainable agricultural development.

How to choose a large wheel compost turning machine model?

When purchasing a large wheel compost turning machine, the model selection is directly related to production efficiency and cost control. Our LP series models need to be accurately selected in combination with the company’s production capacity and needs.
