Compound fertilizer rotary granulator machine technology and advantages

Introduction to Rotary granulator machine:

Zhengzhou Tianci Heavy Industry Rotary granulator machine, also called rotary drum granulator, is one of the key pieces of equipment in the compound fertilizer industry. It is suitable for cold and hot granulation and mass production of high, medium, and low concentration compound fertilizer.

Rotary granulator machine process for compound fertilizer:

The use of rotary granulator machine in compound fertilizer production line mainly has the following 9 process elements.
1. Transport nitrogen, phosphorus, potassium, filling material, and other qualified raw materials to relevant weighing equipment.
2. After weighing the raw materials are transported to the mixer for strong mixing.
3. Conveying to rotary Granulator machine, at the same time through the saturated steam, the material with rotary Granulator machine rotary friction generated to form a rolling bed, the extrusion pressure generated by rolling makes the material containing liquid phase agglomeration into small particles, These small particles become the core and adhere to the surrounding powder to form qualified particles.
4. Transfer to rotary dryer for heat exchange with heat from hot blast stove.
5. It is transported to the hot sieving to sort the particles, and the fine particles are directly returned to the granulator, as the core to continue to participate in the adhesion of the particles into balls.
6. After the screening, the semi-finished particles are transported to the rotary cooling machine, and the fertilizer is cooled by natural or forced cold air. The large particles are crushed by the mill and then returned to the pelletizing machine to continue to participate in pelleting.
7. The qualified products after screening shall be transported to the coating machine for coating treatment.
8. Transport to automatic weighing and packing machine for weighing packaging, and storage.
9. Drying, cooling, and workshop dust after cyclone dust collector, maze dust room, wet washing three treatment discharge.

The use of rotary granulator machine technology to produce compound fertilizer has the following advantages:

1. In the drum in the material layer through the steam to improve the temperature of granulation material, granulation material salts dissolved, achieve low moisture content to obtain high liquid volume to meet the material granulation liquid volume, while reducing the drying process evaporation water.
2. According to the needs of the drum to the material layer through ammonia, so that the material reaction.
3. The inner wall of the drum is lined with a number of soft rubber boards or polypropylene boards, and the corresponding position of the cylinder body is open with air holes. When the inner lining is transferred from the lower part to the upper part of the cylinder, the inner lining will sag due to the relation of self-weight, so that the material attached to the inner lining will fall due to gravity, so as to achieve the function of automatic cleaning of the material.
4. During operation, the operator can observe the material forming situation at any time and take corresponding measures in time according to the need to ensure the normal operation of the system.
5. Wide adaptability of production raw materials: low solubility (calcium, calcium chloride, ammonium sulfate, potassium sulfate, potassium chloride, etc.) and high solubility (urea, ammonium nitrate, ammonium phosphate, etc.) raw materials can be used as required, but also with some organic matter and trace elements.

Rotary granulator machine product varieties:

It can produce various series of products such as inorganic compound fertilizer, organic fertilizer, organic (inorganic) compound fertilizer, and so on, with nutrients ranging from 20% to 48% of nitrogen, phosphorus, and potassium.
