The XGJ vertical ring pellet machine is a patented product of YULONG, incorporating advanced technologies from both domestic and international sources. It features a vertical ring mold that prevents material blockage, a double-layer mold that significantly increases efficiency, and a high-alloy steel mold that extends service life. The independent high-pressure lubrication system ensures cleanliness and unobstructed operation. This machine is ideal for materials with low adhesion and shaping rate, such as rice husk, peanut shells, wood chips, tree bark, crop straws, rubber, cement, ash, and chemical materials. It works best with raw materials having a moisture content between 10% and 15%, and particle size about two-thirds of the final pellet size. It is widely used in biomass energy plants, power stations, wood processing factories, fertilizer plants, and chemical facilities, serving as an optimal molding solution.

Why XGJ
Biomass pellets are increasingly popular in various applications such as animal feed, biomass fuel combustion, and residential and industrial heating. They are expected to dominate the global energy market soon, especially in South Korea, Japan, and Europe. With a density of up to 1.2g/cm³, these pellets offer a heat value 30-40 times higher than the original raw materials, making them highly beneficial for environmental protection.
