How to choose the right organic fertilizer granulator?

Date:2024/06/29

 Granulation is an important process in the production of granular fertilizer, which is not only related to the internal and external quality of granular fertilizer products, but also related to the size of the output and cost, and the granulation production process in addition to the physical and chemical properties of the material itself, but also closely related to the form and mechanical properties of granulation equipment. The control index of the granulation process is mainly the water content of the material, and it is generally more appropriate to adjust the water content of the material to 50% ~ 55%. The prilling effect of steam humidified material is the best, followed by hot water prilling is better than cold water prilling. Too much water in the material will result in the formation of spherules with large particle size, and too little water in the material will result in low granulation rate of loose sandy powder. The main types of granulation equipment are disk granulator, drum granulator, extrusion granulator and so on.

Disc Granulator(Pan Granulator)
The particles produced by the disc granulator are spherical, the size of the particles is related to the tilt Angle of the disc and the amount of water added, and the operation is intuitive, easy to control and adjust, and the cost is low. The machine has the characteristics of uniform granulation, high granulation rate, beautiful finished particles, size and diameter can be controlled, stable operation, long service life and so on. It is widely used in organic fertilizer factory, compound fertilizer factory and sludge garbage processing. Mine, chemical and feed industry and other fields. The disadvantage of the equipment is that the output of a single equipment is low, if several transmission equipment need to be connected in parallel, the equipment can not be sealed, the dust is large, and the dust and waste gas are easy to spill.

Rotary Drum Granulator
Drum granulator is a kind of molding machine that can manufacture material into a specific shape, which is suitable for cold and hot granulation and large-scale production of high, medium and low concentration compound fertilizer. The special rubber plate lining or acid-resistant stainless steel lining is used in the cylinder body to realize automatic scar removal and tumor removal. At the same time, the traditional scraper device is abolished. The advantages are that the single equipment has large production capacity, good tightness, dust and waste gas do not spill, easy to set automatic control of feeding and spraying, long stay time of materials in the cylinder body, high particle strength. At present, large and medium-sized fertilizer manufacturers all use rotary drum granulation. There are also some factories that use the disc granulator and drum granulator in series for secondary granulation, and the effect is also good.

Extrusion granulator(Press granulator)
It is mainly for roller type, double roller type, single axis type, the shape of the particle is mainly based on the shape of the ball and socket on the roller skin. At present, there is a large range of choices: pillow shape, semi-round pellet, rod shape, pill pill shape, walnut shape, flat ball and square strip shape.
Extrusion granulator is dry granulation, material moisture is less than 20%, and there is no need to add additional water in the granulation process. After the granulation is completed, there is no need to use the dryer for drying treatment, saving the investment of equipment and drying energy consumption.
