How should the drum granulator and the disc granulator be chosen?


Drum granulator and disc granulator are two kinds of fertilizer granulator machine commonly used in the fertilizer production industry and what are the differences between them?
Drum granulation machine is one of the key equipment in fertilizer production industry, which is suitable for large-scale production of cold, hot granulation and high and medium-low compound fertilizer. The main mode of work is the group grain wet method granulation, through a certain amount of water or steam, so that the basic fertilizer in the barrel after wetting after a full chemical reaction, in a certain liquid phase conditions, with the rotation of the barrel body movement, so that the material particles between the formation of squeeze pressure reunion into a ball. Main features: the main advantage of the drum granulation machine is to use steam heating to wet, improve the temperature of the granulation material itself, reduce the granulation moisture, reduce the dryer load, improve the efficiency. The use of drum granulation machine granulation rate of up to 70%, and the equipment operation is simple, the working elasticity is large, easy to repair. The barrel body uses ultra-high molecular weight polyethylene (UHMW-PE) lining, to achieve automatic scarring, de-tumor, the elimination of the traditional scraper device, put an end to the phenomenon of material sticking wall, reduce the labor intensity of workers, and greatly extend the service life of the equipment. The machine has the characteristics of high ball strength, good appearance quality, corrosion resistance, wear resistance, low energy consumption, long service life, convenient operation and maintenance. Drum granulator is widely used in fertilizer manufacturing process.

The disc granulation machine (also known as the ball plate) is one of the main equipments of compound fertilizer, organic fertilizer and organic inorganic fertilizer granulation. Its organic fertilizer disc granulation machine corner using the overall arc structure, the grain ingressrate can reach more than 95%. Organic fertilizer disc grain plate with three outlets, easy to intermittent production operations, greatly reducing the labor intensity, improve labor efficiency. Disc granulator and electric motor using flexible belt transmission, starting smoothly, slowing down the impact, improve the service life of disc granulation machine equipment. Organic fertilizer disc granulation machine plate bottom with a number of radiation steel plate to strengthen, durable, never deformation. Organic fertilizer disc granulation machine thickened, aggravated, solid base design, no ground-foot bolt snout, smooth operation. The main gear of the compound fertilizer granulation machine is quenched at high frequency, and the service life is increased by 1 times. Compound fertilizer disc granulation machine granulation plate lining high-strength fiberglass, corrosion and durable. This surface has the advantages of uniform granulation, high granulation rate, smooth operation, durable equipment, long service life and so on. Disc granulator can also be used with organic fertilizer manufacturing process.
 Disc granulator machine
Advantages: uniform granulation, low return, production capacity.
Disadvantages: The pretreatment of materials cannot be carried out, dust and smoke pollution is more serious.
 Drum granulator machine
Advantages: By raising the temperature of granulation to improve the liquid phase in the base material, to promote the material in the lower water content of the ball, with easy to dry, energy saving, reduce consumption advantages. Disadvantages: When the process condition stake is not well controlled, the return material is higher than the disc granulation machine.

We are fertilizer machine manufacturers, disc granulator and turnstock granulator are our patent products, these two fertilizer granulator can not only produce organic fertilizer but also compound fertilizer.
