High-Efficiency Granulator Machinery

Product Application: Dry granulation process involves squeezing powder between two counter-rotating rollers to produce a continuous sheet or ribbon. The DH series dry roll press granulator compresses powdery materials (moisture content ≤1%) into tablets, which are then broken into granules and screened.

During roller pressing, the density of materials increases 1.5–3 times, reaching specific granular strength demands. This method relies purely on external mechanical pressure.

Working Principle

Batching system: Weigh raw materials according to formula using belt scales.

Mixer: Ensure uniform feeding of materials.

Bucket elevator: Lift material to the silo.

Compactor: Double rollers compress dry powder into high-hardness flakes.

Crusher: Break bar-shaped products into 2-4mm irregular granules.

Rotary Screen: Sieve products; recycle dust and unqualified sizes.

Coating machine: Optional surface treatment to avoid clumping.

Packaging: Automatic packing into 25-50kg or TON-bags.

Dust Collection: Cyclone and bag filters remove particles for a clean workshop.

Components & Results

Various Roller Types: Available in different patterns to suit material characteristics.

Finished Products: High-quality irregular granules with adjustable strength.

Frequently Asked Questions

What is the moisture requirement for raw materials?

The dry granulation process requires the moisture content of the powdery materials to be ≤1% for optimal compression.

Is it possible to adjust the size of the final granules?

Yes, the final granule size is typically 2-5mm. The size can be customized by designing specific crusher mesh dimensions.

Does this machine require any chemical additives or binders?

No, materials are forced into shape through mechanical pressure alone, ensuring high purity for the final product.

Can the machine handle different types of raw materials?

A wide range of materials can be processed, including Zinc oxide, Potassium sulphate, Ammonium sulphate, and various fertilizers.

What are the energy consumption benefits?

Since it is a dry process, there is no need for a subsequent drying stage, which significantly reduces energy consumption and shortens the production flow.

How is the dust controlled during production?

The system uses a two-stage dust removal process consisting of a cyclone dust collector and a bag filter to maintain a clean working environment.
