For small and medium-sized fertilizer companies (with daily production capacity of 20-100 tons), granulation equipment must meet the three key requirements of cost control, ease of operation, and adaptability to a wide range of product categories. The disc granulator, with its unique advantages, is the preferred choice for these enterprises. Its simple structure and low investment cost ensure consistent production of high-quality granules, making it a perfect match for small and medium-sized batch production.

The core component of the disc granulator is a tilted circular turntable. Pre-treated raw materials are fed into the turntable, which is then rotated by a motor. Centrifugal force, gravity, and friction cause the material to roll along the inner wall of the turntable, forming spherical granules. Once the granules reach the desired size, gravity pulls them over the edge of the turntable, completing the granulation process.

Compared to other granulation equipment, this system offers significant advantages: First, the procurement and installation costs are only 50%-60% of those of a ring die granulator with the same production capacity, reducing initial investment for small and medium-sized enterprises. Second, it is easy to operate, requiring only one or two people to adjust the rotation speed and tilt angle to control particle size, eliminating the need for specialized technicians. Third, it offers flexible production changes. Changing fertilizer types requires only cleaning residual material from the turntable, and preparation can be completed within an hour, making it suitable for small and medium-sized enterprises' demand for "multi-variety, small-batch" orders.

Furthermore, its granulation rate exceeds 85%, and its pellets are highly rounded, meeting the commercial quality requirements of basic fertilizers.
