How to improve the pelleting effect of compound fertilizer of pan granulator

2019/11/05
The diversification of raw materials promotes the diversification of compound fertilizer granulation equipment. Selecting the fertilizer granulator machine suitable for raw materials can maximize the efficiency of the whole NPK fertilizer production line and improve the production efficiency. Pan granulator is a kind of machine commonly used in the production of compound fertilizer. How to improve the granulation effect of compound fertilizer when using this machine to produce granulation?

Our disc granulator is lined with high-strength fiberglass, which is corrosion-resistant and durable. The main gear of disc granulator is quenched by high frequency, and its service life is doubled. Any equipment has its advantages and disadvantages. As an old model, pan granulator has been improved many times, but it is still popular for its wide adaptability to raw materials. In NPK fertilizer production, when the raw materials are added in the disc continuously, the particles fall into the lower belt conveyor through centrifugal force under the effect of centrifugal force and enter the next stage of treatment.

The viscosity of raw materials has a great influence on the pelletizing effect of disc granulator, so how to improve the viscosity of NPK fertilizer production.

1. Smash the materials to make them more than 80 mesh, so that the viscosity of the materials will be improved a lot, and at the same time, the strength and smoothness of the compound fertilizer particles will be improved.

2. Whether the temperature is suitable for production is also a factor affecting the viscosity of materials. According to the past production experience, the viscosity of general materials will increase with the increase of material temperature. Therefore, spray water for granulation in production to improve the viscosity of materials.

3. Some viscosity conditioners can be added properly during production to improve the viscosity of materials.

These are the common methods to improve the viscosity of materials. It is not only necessary to pay attention to the viscosity of materials, but also pay attention to whether the compound fertilizer production process is beneficial to the roundness of the fertilizer particles.
