The rotary drum granulator is one of the most widely used and mature core granulation equipment in organic fertilizer production lines. It is particularly suitable for large-scale, continuous production of granular fertilizers such as organic fertilizers, organic-inorganic compound fertilizers, and bio-organic fertilizers. This machine features an attractive appearance, simple operation, low energy consumption, long life, uniform drying, and easy maintenance. It is a leading granulation equipment in China and is suitable for both cold and hot granulation, as well as large-scale production of high-, medium-, and low-concentration compound fertilizers. This product is now widely used throughout China.
1. Large processing capacity and continuous production: It is well suited for large-scale industrial production, with a wide range of production capacities (from a few tons/hour to dozens of tons/hour).
2. High granulation rate and strong granule strength: The granules formed through rolling agglomeration are relatively round and dense, with high compressive strength and resistance to breakage, making them easier to package, store, and transport.
3. Strong adaptability: It can process a wide range of raw materials and can process a variety of organic materials (such as livestock and poultry manure, straw, sludge, food waste, and fermentation products such as mushroom
residue) as well as mixtures with inorganic fertilizers.
4. Intuitive operation and relatively easy maintenance: The relatively simple structure and stable operation make it easy for operators to control and monitor.
By utilizing high-speed rotation and mechanical stirring and the resulting air power, fine powder materials are continuously mixed, granulated, spheroidized, and compacted in the machine, thereby achieving the purpose of
granulation. The particle shape is spherical, with a sphericity of ≥0.7, a particle size generally between 0.3-3 mm, and a granulation rate of ≥90%. The particle diameter can be appropriately adjusted by the material moisture content, mixing amount, and spindle speed. Generally, the lower the mixing amount, the higher the speed, and the smaller the particles, and vice versa.
