Rotary Drum Granulator Compound Fertilizer Granules Making Machine

Production overview of rotary drum granulator

The newly developed organic fertilizer rotary drum granulator is a molding machine which can make the material into a specific shape. Drum granulator is one of the key equipment in the compound fertilizer industry. It is suitable for mass production of cold, hot granule and high and low concentration compound fertilizer.

Features of rotary drum granulator

(1) Drum granulator is one of the key equipment in compound fertilizer industry.

(2) It is suitable for hot and cold granulation and high, medium and low concentrations of mass production of compound fertilizer.

(3) The shell of the machine uses special rubber slab lining or acid-resistant stainless lining board which realizes auto scar removal and de-tumor instead of traditional drawknife equipment

(4) High balling strength, good appearance, corrosion resistance, wear resistance, low energy consumption, long service life, easy operation and maintenance, etc.

Working Principle of rotary drum granulator

Using high speed rotating mechanical shearing force and the resulting air power, making continuous implementation of the fine powder material in the machine mixing, granulating, spheroidizing, density and other processes, which achieves the goal of the granulation. The shape of particles is spherical; the spherical degree is 0.7 or higher; the particle size is generally between 0.3 and 3 mm; granulating rate is 90% or higher; the size of particle diameter can be adjusted according to the mixture quantity and spindle speed; generally, the lower the mixing volume, the higher the rotational speed, the smaller the particle, and vice versa.
