Kaolin is a non-metallic mineral with kaolinite as its main component, which has the characteristics of fineness, strong adsorption and high chemical stability. Due to its unique physical and chemical properties, kaolin has been widely used in agriculture and fertilizer industry, especially in organic fertilizer, slow-release fertilizer, compound fertilizer, potting soil, foliar fertilizer, pesticide carrier and other fields, playing an important role. Kaolin granulator can process powdered or slurry kaolin into uniform and fluid particles to increase the added value of products.

How to choose a suitable kaolin granulator

To choose a suitable kaolin granulator, the following key factors need to be considered:

1. Granulation method

Different process requirements determine different granulation methods. Common kaolin granulation methods include:

Drum granulator: suitable for large-scale production, uniform particles, high ball formation rate.

Disc granulator: suitable for small batch production, flexible granulation, easy adjustment.

Extrusion granulator: suitable for high-density, high-strength particle production.

Spray granulator: suitable for rapid drying and molding of liquid kaolin slurry.

2. Production capacity

Select equipment with different production capacities according to production needs, such as:

Small-scale production: 0.5-2 tons/hour

Medium-scale production: 5-10 tons/hour

Large-scale production: more than 20 tons/hour

3. Particle size

Different applications have different requirements for particle size. Generally, granulators can adjust the particle diameter range between 0.5mm-10mm to meet the needs of industries such as ceramics, rubber, and coatings.

4. Equipment material

Stainless steel material: corrosion-resistant, suitable for high-purity kaolin production.

Carbon steel material: low cost, suitable for general industrial use.

5. Energy consumption and environmental protection

Choosing a granulator with low energy consumption and environmental protection standards can reduce the operating costs of the enterprise and comply with national environmental protection regulations.

Kaolin granulation production line process flow

Kaolin granulation is not a single device can be completed, usually requires a whole production line, the common kaolin granulation production line includes the following equipment:

1. Crushing and grinding system: Raymond mill or jaw crusher grinds kaolin into fine powder to improve the granulation effect.

2. Batching and mixing system: evenly mix the powder, and other nutrient raw materials can be added during the process.

3. Granulator: core equipment, choose different types of granulators according to particle size requirements.

4. Drying and cooling system: rotary dryer quickly dries the particles to improve strength. Cooler reduces the temperature of the particles for subsequent packaging.

5. Screening and packaging system: vibration screening machine screens particles that meet the specifications and removes unqualified products. Automatic packaging machine packs the granular kaolin into bags for easy storage and transportation.

Application of kaolin after granulation

Granulated kaolin has better fluidity and applicability, and is widely used in many industries:

Ceramic industry, paper industry, rubber and plastic industry, coating and paint industry, agriculture and fertilizer industry

Choosing a suitable kaolin granulator can not only improve production efficiency, but also improve product performance and expand the application field. When purchasing a granulator, enterprises should make comprehensive considerations based on factors such as granulation method, production capacity, particle size, equipment material, energy consumption and environmental protection, and at the same time, they should also equip a complete kaolin granulation production line to ensure product quality and market competitiveness.
