The new type organic fertilizer granulator is one of the commonly used organic fertilizer granulator. It is made up of many spirally arranged agitators with internal structure. It is also called internal rotating agitator granulator. It is also called wet granulator because it is suitable for the granulation of many raw materials with large water content. It is widely used for the granulation of organic fertilizer chemical raw materials.
The working principle of the new organic fertilizer granulator: the new organic fertilizer granulator uses the mechanical stirring force of high-speed rotation and the resulting aerodynamic force to continuously realize the mixing, granulation, spheroidization, densification and other processes of fine powder in the machine, so as to achieve the purpose of granulation.
The particle shape is spherical, the sphericity is ≥ 0.7, the particle size is generally between 0.3-3mm, and the granulation rate is ≥ 90%. The particle diameter can be properly adjusted by the material mixing amount and the spindle speed. Generally, the lower the mixing amount is, the higher the speed is, the smaller the particles are, and vice versa.
Application scope: the new organic fertilizer granulator is especially suitable for the granulation of light and fine powder materials. The finer the basic particles are, the higher the sphericity of the particles is and the better the quality of the pellets is.
Typical application materials: chicken manure, pig manure, cow manure, tanli, clay, kaolin, etc. It is specially used for granulating organic fermentation fertilizer with organic fertilizer raw materials, such as manure and urine of livestock and poultry, compost fertilizer, green fertilizer, sea fertilizer, cake fertilizer, peat fertilizer, soil manure, three wastes, microorganism and other urban domestic wastes. The particles are pellets.
The qualified granulation rate of the new organic fertilizer granulator is more than 80-90%, which is suitable for various formulations. The compressive strength of organic fertilizer is higher than that of disc and drum, and the big ball rate is lower than 15%. The particle size uniformity can be adjusted by the stepless speed regulation function of the machine according to the user’s requirements. The machine is more suitable for granulating organic fertilizer directly after fermentation, saving drying process and greatly reducing manufacturing cost.
