Product Description

Способ сухого гранулирования осуществляется следующим образом: порошок сжимается вращающимися в противоположном направлении двумя валами, чтобы получить цельный лист материала. Гранулятор сухого вальцования серии DH использует технологию сухой прокатки для прессования порошкообразных материалов с содержанием влаги ≤1% на один лист.

Frequently Asked Questions
What is the required moisture content for the raw materials?
The DH series dry granulation roll compactor requires a moisture content of ≤1% to ensure optimal compression and granule formation.
Can the size of the final granules be adjusted?
Yes, the final granule size (typically 2-5mm) can be controlled by selecting the appropriate screen size in the crusher and sifting units.
Does this process require additional binders or drying?
No. This is a dry granulation process that uses high mechanical pressure to bond particles, eliminating the need for additives or subsequent drying stages.
What materials are suitable for this machine?
It is widely used for fertilizers (like Ammonium Sulfate and Potassium Sulfate), chemical powders, and other dry materials requiring high-density granulation.
How is the dust managed during the production process?
The system includes a two-stage dust collection process using a cyclone dust collector for large particles and a bag filter for residual fine dust, which is then recycled back into the process.
Is the machine easy to maintain?
Yes, the DH series features a compact structure designed for easy maintenance, high automation, and low energy consumption.
