Product Description

DH series dry roll press granulator adopts dry rolling technology to compress powdery materials with moisture content ≤1% into pieces or tablets. The process involves breaking these into granules and screening to meet application requirements. This method relies on external mechanical pressure to force material through the gap between two counter-rotating rollers, increasing material density by 1.5~3 times.

Limestone Granulator Machine

Working Principle

Batching: Weigh raw materials using belt scales.
Mixing: Ensure uniform feeding via industrial mixer.
Elevation: Bucket elevator lifts material to the silo.
Compaction: Double rollers compress dry powder into high-hardness flakes.
Crushing: Bar-shaped products are crushed into 2-4mm irregular granules.
Screening: Rotary screen sieves final products; dust is recycled.
Coating: Optional surface treatment to avoid clumping.
Packaging: Automatic bagging (25-50kg or Ton-bags).
Dust Collection: Two-stage system (cyclone + bag filter) for clean operation.

Frequently Asked Questions

What moisture content is required for dry granulation?
The powdery materials should ideally have a moisture content of ≤1% for optimal dry roll pressing.
Can the granule size be customized?
Yes, the standard size is 2-5mm, but the crusher mesh can be designed to meet your specific size requirements.
Are binders or additives necessary?
No, materials are compressed via mechanical pressure only, ensuring the purity of the final product.
How do I adjust the hardness of the granules?
Granular strength can be freely adjusted by modifying the hydraulic pressure of the rollers.
What materials can be processed with this machine?
It is widely used for potassium fertilizers, limestone, ammonium sulphate, and various chemical powders.
Is the system environmentally friendly?
Yes, it features a two-stage dust collection process (cyclone and bag filter) to recycle dust and control pollution.
