Spray Granulator

The spray granulation machine is a device used to convert solutions or slurries into granular products. It is widely applied in multiple industries such as compound fertilizers, organic fertilizers, food, and medicine.
Usage: Manufacturing granular products
Production capacity: 2 – 12 tons per hour
Particle diameter: 0.5 – 5mm
Applicable raw materials: Solution or slurry materials

Description

The spray granulation machine is an industrial equipment that produces granular products with specific particle size distribution, strength and physical properties through a process of atomizing, drying, solidifying and forming by spraying liquid or paste-like raw materials. It mainly consists of a cylinder, drive unit, feeding device, discharging device, atomization system, heating device, transmission device, electrical system, etc.
Characteristics of the spray granulation machine:
Diameter: Φ3.5 – Φ4.5m
Capacity: 2 – 12 tons per hour
High production efficiency, good product quality, low operating cost, wide application range
Various materials are available, and stainless steel material can be selected.
Applications of the spray granulation machine:
1. Fertilizer industry: It is a key equipment in the production process of compound fertilizers, ammonium phosphate, etc., and can turn various fertilizer raw materials into granular products.
Advantages: Improve the stability, fluidity and application effect of fertilizers.
2. Environmental protection industry: Used for sludge granulation and drying in the field of environmental protection.
Advantages: Achieve the reduction, stabilization and harmless treatment of sludge, and facilitate subsequent transportation and disposal.
3. Other industries: In the food, medicine, dye, non-metallic mineral processing, catalyst and laundry detergent industries, it can turn related materials into granular products that meet requirements.
Advantages: Improve the physical properties of materials, facilitate storage, transportation and use.

Faqs

The slurry contains unfiltered impurities, coarse fibers or large particles; the slurry concentration is too high and its fluidity is poor; the spray nozzle has not been cleaned for a long time and the residual materials have dried and hardened.
The drying temperature was insufficient, resulting in incomplete evaporation of moisture within the particles; the slurry concentration was low, leading to insufficient particle density; the residence time of the materials in the fluidized bed was too short, causing insufficient curing.
