Difficult-to-granulate materials such as easily softening raw materials and those with low allowable temperatures.
● Granulation of difficult raw materials and small diameters that were challenging with conventional machines is possible. Since processes such as kneading, high friction, and high compression are unnecessary, granulation of difficult-to-process raw materials like softening materials and heat-generating materials, as well as small diameters (φ0.7–5mm) that were difficult to granulate with conventional semi-dry roll granulators, is achievable.
● Contributes to energy savings with low moisture treatment. Depending on the raw materials, the moisture required during granulation is less compared to screw extrusion granulators.
● Produces cylindrical pellets. The roller extrusion pressure is applied straight to the screen die, resulting in beautiful cylindrical pellets.
● Achieves stable load through uniform dispersion. The supply of raw materials is by natural drop. They are evenly dispersed in the granulation chamber and smoothly enter under the rollers, resulting in extremely stable granulation load.
● Easy adjustment and cleaning. The roller is adjusted only by the shaft nut, allowing for uniform pressure application to the screen die. Additionally, using a hoist, the removal of the roller and screen die can be done in a short time. The simple mechanism also makes cleaning easy.
● High efficiency and long lifespan. The large diameter of the roller allows for good penetration of the raw materials, achieving high-efficiency processing. Furthermore, by adopting larger bearings, the strength and durability are enhanced, resulting in a longer lifespan.
