Liquid spray granulator ordered by a user in the Philippines

Liquid spray granulator ordered by a user in the Philippines

The liquid spray granulator ordered by users in the Philippines is suitable for various types of farms, organic fertilizer plants, and sludge and waste treatment plants for fecal treatment or organic fertilizer raw material processing. With the organic fertilizer market becoming increasingly broad, starting an organic fertilizer processing industry is a good choice that conforms to the times.

Working Principle

1. Atomization Process: Molten liquid or slurry enters the atomizing nozzle under the action of a high-pressure pump and is atomized into fine droplets. Common atomization methods include pressure type, centrifugal type and airflow type. For example, the pressure atomizer ejects the slurry from the nozzle through a high-pressure pump to form a conical spray field.
2. Granulation Process: The atomized droplets come into contact with fine particle nuclei in the rotating cylinder, and the droplets adhere to the surface of the nuclei. As the cylinder rotates, the lifting plates continuously lift the materials at the lower part of the cylinder to the upper part and drop them to form a continuous material curtain. The droplets are sprayed onto the material curtain, making the fine powder gradually grow into spherical particles.
3. Drying Process: Under the action of high-temperature drying medium, the particles adhering to the droplets quickly complete the heat and mass transfer process, the moisture is evaporated, and the particles are dried. The dried particles are discharged from the tail, and after screening, the particles with qualified particle size are used as products, and the unqualified fine particles are returned as nuclei.

Structural Features

1. Cylinder: Generally made of carbon steel, installed obliquely on the foundation, with feed and discharge boxes fixed at both ends and sealing devices. A rolling ring is installed outside the cylinder, supported on the support roller bracket, and driven to rotate by a motor through a reducer.
2. Slurry Spray Gun: Inserted into the cylinder from the end of the feed box, its nozzle usually adopts an airflow-type two-way atomization structure, which can rotate to a certain extent in the cylinder to adjust the injection point of the slurry.
3. Lifting Plates: The cylinder is divided into granulation area, drying area, etc. There are spiral material guiding lifting plates at the front end of the granulation area, and multi-section elevating lifting plates are arranged in the subsequent granulation area and drying area, which can make the lifted materials sprinkle evenly to form a dense material curtain.
4. Other Components: Also include large gears, small gears, thrust wheel sets, exhaust gas discharge pipes and other components. Some equipment is equipped with hammer devices on the outer wall of the cylinder end to knock off the bonded materials on the inner wall of the cylinder.

Main Characteristics

1. Large Production Capacity: Suitable for large-scale continuous industrial production operations.
2. Good Product Quality: The final product is almost all dense spherical particles with concentrated particle size distribution, good fluidity and not easy to absorb moisture.
3. Strong Adaptability: Can be used for drying and granulation of various liquid materials, such as monosodium glutamate tail liquid, alcohol tail liquid, papermaking black liquor and other industrial waste liquids.
