    Product Introduction

    The vertical mill, also known as a roller mill, is widely used for large-scale and ultrafine material grinding in the cement, chemical, coal, and power generation industries. It is an ideal equipment for the grinding industry, integrating crushing, drying, grinding, grading, and conveying. It can be used in coal pulverization to achieve product fineness that meets industry standards.

    Key Advantages
    ● High grinding efficiency, low power consumption
    ● Simple and reliable operation, stable product quality
    ● Simple process flow, simultaneously completing grinding, drying, and powder selection
    ● Small footprint, compact layout, and low construction investment

    Operating Principle
    An electric motor drives the grinding disc through a reducer. Simultaneously, hot air enters the vertical mill through the air inlet. Material falls through the discharge port onto the center of the grinding disc. Centrifugal force moves the material from the center toward the edge of the grinding disc. Passing through the annular grooves on the grinding disc, it is crushed by the grinding rollers. The crushed material continues to move toward the edge of the grinding disc until it is carried away by the airflow from the air ring. Larger particles fall back onto the grinding disc for further crushing. As the material in the airflow passes through the upper separator, guide vanes pull the coarse material from the conical hopper onto the grinding disc. Fine powder exits the mill along with the airflow and is collected by the system's dust collector. The collected powder becomes the finished product of the vertical mill. Contact with the air in the housing dries the material to the desired dryness and moisture content. By adjusting the angle of the separator guide blade (not adjustable for small vertical mills) and the speed of the separator rotor, the required coarseness of the product can be achieved.

  • 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.
