Disc Granulator with Simple Dust Hood & Dust Collection System

A disc granulator (also known as a pan pelletizer) is one of the most efficient wet granulator machines for organic and NPK fertilizer production. During continuous tumbling, raw powders and liquid sprays often create light airborne dust around the pan.

To maintain a clean working environment and reduce material waste, equipping the fertilizer granulator machine with a simple dust hood and compact dust collection system provides an economical, practical, and highly effective solution.

Practical Features of the Simple Dust Hood System

The dust hood is a straightforward protective cover installed over the rotating pan. Combined with a basic exhaust fan and dust collector, it offers three core benefits:

• Dust Containment: Prevents light raw powder from flying out of the pan during high-speed rotation.

• Powder Recovery: Draws fine airborne dust into a simple filter unit, dropping it back into the production line to save raw materials.

• Operator Protection: Keeps the workshop air clean, protecting workers from inhaling airborne fertilizer particles.

• Easy Monitoring: Designed with observation doors, allowing operators to check pellet growth and adjust liquid nozzles without removing the cover.

Disc Granulator Model Specifications (1m to 6m)

We offer custom disc granulators fitted with simple dust hoods across multiple sizes and material configurations:

Material Selection: Carbon Steel vs. Stainless Steel

• Carbon Steel Disc Granulators:

Cost-effective choice for general organic fertilizer compost, fermented poultry manure, and bentonite cat litter processing.

• Stainless Steel Disc Granulators (SUS304 / SUS316L):

Essential for compound fertilizer lines handling corrosive chemical salts, acidic formulas, or high-moisture mixtures, ensuring a longer machine lifespan without rust.

Smart Engineering: Why Choose Dual 3m Pans Instead of a Single 6m Pan?

When expanding plant capacity to reach 8–12 tons per hour, installing two 3-meter disc granulators with individual dust hoods is far superior to buying one large 6-meter unit:

• Better Granule Sphericity & Quality: 3-meter pans allow easier angle and speed adjustments, yielding much more uniform fertilizer pellets.

• Lower Equipment & Freight Cost: 3m granulators fit inside standard shipping containers, saving significant international sea freight expenses.

• Operational Flexibility: If one machine requires routine maintenance or cleaning, the second unit continues running, avoiding a complete factory shutdown.

Frequently Asked Questions

Q: Is the dust hood complicated to operate or maintain?

A: Not at all. It is a simple, low-maintenance protective enclosure equipped with inspection hatches, ensuring easy daily operation, nozzle cleaning, and visual checks.

Q: Can the simple dust collection system reduce material loss?

A: Yes. The suction system captures floating fine powder inside the hood and collects it so it can be re-fed into the granulator, directly improving material yield.
