DG series double roller granulator, granulation at normal temperature, high forming rate. It can produce oblate particles with φ4–φ10mm and various sheet products. Double roller granulator machine is widely used in the granulation of powder raw materials such as fertilizer, medicine and chemical industry, especially for the production of granular fertilizer such as ammonium sulfate, ammonium chloride, potassium chloride, potassium sulfate, salt, compound fertilizer, binary and ternary compound fertilizer (nutrient content of 25% – 53%). Our company can customize the fertilizer granulation line with an annual output of 30,000–500,000 tons according to customers' requirements. The complete set of equipment has compact process layout, scientific and reasonable, advanced technology, energy saving and consumption reduction, environmental protection, stable operation and convenient maintenance.
The surface hardness of the roller after surface thermal treatment reaches HRC60-65. However, due to the large amount of granulation, some of them will wear after a certain period of time, so they can no longer be granulated. Because the rolls in this double roller granulator machineare vulnerable parts, they need to be replaced after a certain production cycle.

Advantages of Wet Type Double Roller Granulator
Strong raw material compatibility: This double roller granulator smoothly handles high-moisture wet powder like fermented manure and chemical slurry without pre-drying.
Stable forming performance: The double roller granulator machine delivers uniform, solid granules with low breakage rate, supporting continuous mass production.
Simple operation & maintenance: Compact structure reduces jam risks; stainless steel contact parts are easy to clean for food, fertilizer and chemical production.
Cost-effective production: It cuts extra binder input and shortens workflow, lowering overall energy and labor costs compared with disc granulators.
Eco-friendly extrusion: As a practical double roller press granulator, it generates little waste powder, and recycled scraps can re-enter granulation for full raw material utilization.
FAQ
Q: What raw materials can a double roller granulator process?
A: Our double roller granulator handles wet organic powder, mineral powder and fertilizer raw materials. It adapts to moisture 8%-16%, delivers stable granulation rate above 88%, and supports continuous mass production without extra drying steps.
Q: What are the core advantages of this double roller granulator machine?
A: This double roller granulator machine adopts alloy wear-resistant rollers, saves over 40% energy, produces uniform solid granules, and features simple operation, low failure rate and convenient daily maintenance for long-term factory use.
Q: How to adjust particle size of the double roller press granulator?
A: The double roller press granulator realizes different granule sizes by replacing roller molds. We supply customizable molds of 3–12mm, and the press pressure of the double roller press granulator can be adjusted via hydraulic system freely.
Q: What’s the difference between wet type double roller granulator and dry granulation equipment?
A: Our wet type double roller granulator fits materials with moderate water content and avoids excessive dust. The wet type double roller granulator has stronger bonding effect and firmer finished granules for organic fertilizer production lines.
Q: What after-sales service do you provide for china wet type double roller granulator?
A: As a manufacturer, we offer 12-month warranty for our china wet type double roller granulator, free online technical guidance, spare parts supply and on-site installation support for every set of china wet type double roller granulator exported overseas.
