Ring Die Pellet Machine

The Ring Die Pellet Machine is an efficient granulation equipment that compresses the material on the ring die mold through a pressure roller, forming it into cylindrical pellets. Its core feature is a vertically placed, high-speed rotating porous annular mold (ring mold). As a mainstream industrial model in the fields of feed, fertilizer, and large-scale biomass fuel production, it is known for its high yield, high molding rate, and excellent particle quality, making it the preferred equipment for achieving large-scale and continuous commercial production.Working Principle

1. Feeding and distribution: The prepared powdered raw materials are fed into the granulator and evenly distributed to the inner surface area of the ring mold by a rotating feeder.

2. Extrusion and Forming: Two or three pressure rollers (pressure wheels) located inside the ring mold do not rotate with the revolution, but only rotate due to friction. The ring mold is driven by the spindle to rotate at high speed, bringing the material into the wedge-shaped extrusion zone formed by the pressure roller and the ring mold. In this area, the material is subjected to tremendous radial pressure from the pressure roller and is forcefully squeezed through the cylindrical mold hole on the ring mold.

3. Cutting and discharging: The material undergoes high temperature and high pressure in a very short period of time after passing through the mold hole, and its lignin or starch components soften and gelatinize, playing a natural bonding role. The extruded strip material is cut by a cutting blade fixed on the outer shell of the granulator, forming a set length of granular finished product.

Feature

1. High output and stability: The sturdy ring molded roller structure can withstand extremely high pressure, suitable for long-term high-intensity continuous operation, with large single machine output and stable and reliable operation.

2. Excellent particle quality: Particles made under high pressure have high density, hardness, smooth surface, excellent molding rate and uniformity, and have higher commercial value and combustion efficiency.

3. Durability and Long Life: The core ring mold and pressure roller are made of alloy steel and treated with special processes such as carburizing and quenching, which have strong wear resistance, long service life, and high comprehensive economic benefits.

4. High operating efficiency: Horizontal axial transmission, uniform and stable force distribution, easy to integrate with automated feeding and conditioning systems, and outstanding overall operating efficiency.

5. Wide industry applicability: With mature technology, it is the absolute mainstay of large-scale industrial production such as feed, fertilizer, and wood pellets, with extremely high market recognition and popularity.
