Double-Roller Extrusion Granulator

The double-roller extrusion granulator is a new type of equipment developed by our company based on the twin-roller extrusion granulator. It utilizes a dry-free process, produces granules at room temperature, and forms the pellets in a single operation. It boasts a wide range of raw material compatibility and is suitable not only for granulating fertilizers, feed, and chemical industries, but also for rare earth, metallurgy, coal, biological agents, and environmental protection projects. To some extent, it fills a gap in the industry, is at the forefront domestically, and is also a major environmental protection project!

  • The double-roller extrusion granulator operates as follows: an electric motor drives a pulley, which is then transmitted through a speed reducer to a pair of high-pressure rollers with sliding housings, which rotate relative to each other. In the DZJ-I extruder, the two rollers are driven by a set of split gears, while in the DZJ-II extruder, the two rollers are directly driven by two output shafts on a dedicated speed reducer, achieving extrusion and forming. During production, raw materials enter through a hopper, are squeezed and formed by the high-pressure rollers, and then, after demolding, flow freely into the crushing and forming chamber below the rollers. The crushing and shaping power is transmitted by a chain from the sprocket of the active pressure roller shaft to a pair of crushing rollers, which move relative to each other. Crushing and screening occur within the working chamber, and the finished granules pass through a screen into a discharge chute.

    The double-roller extrusion granulator integrates granulation, forming, and screening into a single structure, resulting in an attractive appearance, simple operation, and low energy consumption. Key components, such as the rollers, are made of a new metal material that is corrosion-resistant, wear-resistant, and impact-resistant. The DZG-II model not only possesses these characteristics, but our company has also upgraded the frame, using corrosion-resistant casting as a single unit for the bearing frame, resulting in excellent stability and significantly extending the service life of the rolling bearings and main shaft. The transmission system utilizes a dual-input transmission system, which not only improves the input power ratio but also ensures lubrication and sealing of the transmission gears. This machine boasts a compact structure, excellent stability, good sealing, low noise, and easy operation and maintenance.

  • Rotary Drum Granulator Rotary Drum Granulator
    The rotary drum granulator is a machine for processing powdered or slurry materials into pellets. Its primary operating method is wet granulation. A sufficient amount of water or steam is used to moisten the base fertilizer within the drum, allowing it to undergo a complete chemical reaction. The drum's rotational motion then creates a squeezing force between the material particles, agglomerating them into pellets. The machine boasts an attractive appearance and is suitable for both cold and hot granulation, as well as the large-scale production of high-, medium-, and low-concentration compound fertilizers.

  • Disc Pelletizer Disc Pelletizer
    The disc pelletizer is a new type of tilted disc pelletizing equipment. Its frame is welded from high-quality carbon channel steel, while the pelletizing disc is welded from high-quality carbon steel plates and channel steel, treated with other anti-corrosion treatments. The bottom is reinforced with multiple radial steel strips. The pelletizing rate can reach over 92%. The entire machine's transmission system is of paramount importance, ensuring its overall operation. The motor and reducer mounted on the drive adjustment frame are ISO/9001 certified. The motor drives the pulley, V-belt, reducer, and pinion, which in turn drives the large gear on the pelletizing disc to operate. Both large and small gears utilize high-frequency quenching, doubling their service life. The entire pelletizing disc is fixed to the drive shaft on the adjustment disc, with a taper-fit connection at the column head for a more streamlined design. The automatic material removal system, mounted above the pelletizing disc in a lower frame, is equipped with an automatic material removal plate to remove material adhering to the disc wall during production, significantly extending the machine's service life while saving labor.

  • Agitator Granulator Agitator Granulator
    The agitator granulator is a new type of organic fertilizer granulation equipment, designed and manufactured using a new wet continuous push rod granulation process. It utilizes the high-speed mechanical agitation force and the resulting air dynamics to continuously mix, granulate, spheroidize, and densify the material within the granulator chamber. The material is evenly fed into the granulator chamber by a feeder, where it is agitated and pre-pressed by the agitator to form granules. It can granulate a variety of organic fertilizers, including raw materials such as livestock and poultry manure, composted manure, green manure, sea manure, cake fertilizer, peat, and other organic fermented fertilizers from municipal waste. It is suitable for light, fine powder materials such as chicken manure, pig manure, cow dung, charcoal, clay, and kaolin.
