1.5T Double Roller Granulator for Sale

Firstly, our company upgrade the roller skin material, exterior design, and double roller structure on the new 1.5-ton dry granulator. Also, we manufacture the entire mold with high-chromium alloy material combined with laser quenching process reducing wear and increasing hardness by 30%. This improvement extends the roller’s lifespan and reduces downtime. Secondly, we optimize the internal structure and granulation chamber layout. For example, we innovatively design double spiral roller shafts to ensure continuous granulating of high-moisture sticky materials without clogging. Additionally, the new transmission system and reducer (model ZQ400) with an 18.5kw motor ensure smooth operation. Besides, the hydraulic system intelligently adjusts the roller gap (2-20mm), achieving 96% granulation rate for 3-10mm granules. So it solves industry issues such as organic fertilizer sticking to rollers and breaking pellets in NPK fertilizer manufacturing.

This new 1.5T model increases hourly capacity by 33%, producing 1-2 t/h fertilizer granules versus older 0.8-1.5 t/h per unit. Moreover, it can meet the demands of most compound fertilizer manufacturers and supports multiple machine units in series to expand capacity. For instance, you can buy 6 units of model SXDZJ-1.5 to achieve 10 t/h NPK fertilizer granulation line. The dry granulation process is simple, reducing energy consumption for NPK fertilizer plants. In addition, the transmission system, new motor and reducer decreases unit power consumption from the original 15.8 kWh to 12.2 kWh. Besides, the roller skin with high-quality materials extends its replacement cycle or lifespan from 5,000 hours to over 8,000 hours. Lastly, we offer a single roller extruder granulating machine price of 3,500-4,000 US dollars.

The 1.5T double roller granulator is suitable for compound fertilizers, ammonium chloride, ammonium sulfate, humic acid organic fertilizer, fermented livestock and poultry manure, and other sticky materials with moisture content ≤30%. Thus, customers can produce fertilizer granules with a roundness of 95% and compression strength above 15N, minimizing breakage during transportation.

Especially, it’s effective in compound fertilizer granulation, providing high-density, uniform pellets that enhance improving fertilizer dissolution speed and fertilization effect. For chemical fertilizers like ammonium chloride and ammonium sulfate, the new technology ensures pellet shape improvement, reduces dust, and enhances storage and transportation. Besides, in organic fertilizer production, the granulator adapts to various organic materials and handles high-viscosity materials effectively. So we provide robust equipment for NPK, organic and chemical fertilizer production plant design, and we support efficient fertilizer manufacturing processes.
