Analysis of the characteristics of the rotary drum granulator and the disc granulator

 In the current organic fertilizer industry, there are many types of equipment that can be used as organic fertilizers, and there are different supporting equipments according to different materials. The fertilizer granulator machine is the most important machine. Here we use poultry manure as raw material to analyze the advantages and disadvantages of the two different equipments of the drum chemical granulation equipment and the disc granulator.

Disc granulator machine and granulation process features:
The operation is intuitive, and the operation of the equipment can be grasped at any time. If it is found to be abnormal, it can be adjusted in time.

The size of the particles is determined by the inclination and rotation speed of the disc, and the inclination and rotation speed of the disc can be adjusted. Therefore, the disc granulation process has a wide control range of particle size, is highly adaptable, and has a very high sphericity rate of 70%~90%.

The manure organic fertilizer disk granulation process has short production process, simple structure, low investment and easy operation, and is suitable for small and medium-sized enterprises.

Characteristics of the rotary drum granulator machine and granulation process:
Steam is introduced into the material layer in the drum to increase the temperature of the granulated material, so that the salt of the granulated material is dissolved, and a high liquid phase is obtained at a low moisture content to satisfy the liquid phase required for granulation of the material. At the same time, the amount of evaporated water in the drying process is reduced.

The inner wall of the drum is lined with a plurality of soft rubber sheets or polypropylene sheets, and vent holes are opened at corresponding positions on the cylinder body. When the inner liner is turned from the bottom to the top at the same time, the inner lining is drooped due to its own weight, so that the lining adheres to the material on the lining falls due to gravity, which automatically cleans the material.

During operation, the operator can observe the material into the ball at any time, and take corresponding measures as needed to ensure the normal operation of the system.
