In response to the need for industrial upgrading, the new type organic fertilizer granulator (models YSL-60 to YSL-150) was developed by the Agricultural Machinery Research Institute. Leveraging its accumulated experience in compound fertilizer processing and its unique mixing and granulation method, it has become a practical device for granule production in various fields.
In terms of core technology, the new type organic fertilizer granulator utilizes high-speed rotating stirring teeth to stir, impact, and tumble the mixed material within the granulation drum. Friction, centrifugal force, and the material’s viscosity aggregate the material into granules, eliminating the need for complex extrusion equipment and making it suitable for high-viscosity or fibrous materials. Performance parameters include a production capacity of 1-8 tons/hour, motor power of 37-90 kW, and granule diameter of 1-5 mm. The YSL-60 produces 1-2 tons per hour, making it suitable for small and medium-sized operations; the YSL-150 produces 5-8 tons per hour, making it suitable for large-scale production.
It has a wide range of applications. In the fertilizer sector, livestock and poultry manure, straw, and other materials can be transformed into organic, bio-organic, and compound microbial fertilizers, eliminating caking issues while preserving bacterial activity and producing medium and trace element fertilizers. In the chemical industry, it can be used to granulate sticky raw materials; in the pharmaceutical industry, it can process traditional Chinese medicine granules; and in the feed industry, it can produce livestock and aquatic feed, achieving a “one machine for multiple uses.”
The core advantages are significant. Granulated particles are round and uniform, with good flowability, and are less prone to clumping during storage and transportation. Operation is simple, requiring only training. The low motor power and operating costs make the equipment affordable, making it suitable for small and medium-sized enterprises. Furthermore, it preserves fertilizer activity, extending its shelf life to 8-12 months, promoting the recycling of organic waste and achieving both economic and environmental benefits.
Daily maintenance requires three key points: regular inspections: daily inspection of the feed mechanism and transmission system; weekly inspection of agitator tooth wear; monthly bolt tightening and motor temperature monitoring; cleaning the granulation drum after production; lubricating transmission components according to specifications, and timely replacement of worn parts to ensure stable equipment operation.
This new type organic fertilizer granulator, with its multiple advantages in technology, performance and application, is providing strong support for production upgrades in agriculture, chemical industry, medicine, feed and other fields.
