DH series dry roll press granulator adopts dry rolling technology to compress the powdery materials with moisture content ≤ 5% into pieces or tablets, then going through the processes of breaking into granules and screening to make the lump materials into granules that meet the requirements of application. Dry roll press granulator mainly depends on the manner of external pressure to force the material going through the gap between two relatively turning rollers to compress into laminar particles. During course of roller pressing, the real density of materials can increase 1.5~3 times thus reaching certain demands of granular strength.
DG series double roller granulator adopts no-drying process granulating at normal temperature and once forming. It can produce 2-6mm irregular granules, Φ 3.8-Φ 10mm oblateness granules and all kinds of slice products. It is a multi-purpose machine and widely used to granulate the powder materials of fertilizers, medicine, chemicals, etc, especially suitable for the production of palletized fertilizers such as ammonium bicarbonate, carbamide, ammonium chloride, ammonium sulfate, potassium chloride, potassium sulfate, salt, binary, ternary compound fertilizers(Nutrient content 25%-53%), blended fertilizers and so on. Our company can tailor the chemical fertilizer production lines from 30, 000 to 500, 000 T/Y according to the requirements of the customers. The complete sets of the equipment are in compact layout process, scientific and rational, leading technology, energy saving, environmental protection without waste emissions, operation stability, and easy maintenance.
