Simple Operated Ammonium Sulfate Granulator
Dry granulation is conducted through a specialized process where powder is squeezed between two counter-rotating rollers to produce a continuous sheet or ribbon of materials.
DH series dry roll press granulator adopts dry rolling technology to compress powdery materials (moisture ≤1%) into tablets, followed by breaking and screening to meet granular requirements.
Main Features
◈Adjustable granular strength via roller pressure.
◈Cycle operations for continuous high-yield production.
◈No additives required; guarantees product purity.
◈Eliminates follow-up drying process, saving energy.
◈Compact structure with low maintenance and failure rate.
◈Frequency adjustment control for high automation.
◈Reduces environmental pollution and packaging costs.
◈Wide range of raw material applicability.

Frequently Asked Questions
What is the required moisture content for the raw materials?
The dry roll press granulation process requires the moisture content of powdery materials to be less than or equal to 1%.
Can the granule size be adjusted?
Yes, the final granule size (standard 2-5mm) can be customized by changing the mesh size of the crusher and screening equipment.
Is a drying process needed after granulation?
No. Since it uses a dry granulation method, the powders are compressed directly into granules without any liquid binders, eliminating the need for drying.
How do you control the hardness of the final granules?
The granular strength can be adjusted by modifying the mechanical pressure applied by the double rollers in the compactor.
What kind of materials are suitable for this granulator?
A wide range of dry powders can be used, including Zinc oxide, Ammonium sulfate, Potassium sulfate, and various compound fertilizers.
Is the machine easy to maintain?
Yes, the machine features a compact structure, low failure rate, and is designed for simple operation and long-term continuous production.
