    Working Principle

    The main motor drives the spindle and turntable to rotate through the reducer, and the roller pin at the edge of the turntable drives dozens of grinding rollers to roll in the grinding ring raceway. The bulk material is broken into small particles by the hammer crusher and sent to the storage bin by the elevator, and then through the vibration feeder and the inclined feed pipe, the material is evenly sent to the bulk tray on the upper part of the turntable. The material is scattered around the circle under the action of centrifugal force, and falls into the raceway of the grinding ring, which is impacted by the ring roller, rolled and ground, and becomes powder after the processing of three layers of ring paths. The high pressure fan inhales the external air into the machine through the suction effect, and brings the crushed material into the powder separator. The rotating impeller in the separator makes the coarse material fall back and re-grind, and the fine powder that meets the requirements enters the cyclone powder collector with the air flow and is discharged by the discharge valve at the lower part of the product, while the air flow with a small amount of fine dust is discharged through the fan and muffler after the pulse dust collector.

    Characteristic and feature of Z series micro-powder grinder
    High efficiency and energy saving: In the fineness of the finished product and the motor power are the same, the output is more than twice that of the air mill, stirring mill and ball mill.
    Long service life of wearing parts: The grinding roller and grinding ring are made of special materials, which greatly improves the utilization degree. Generally up to more than one year; processing calcium carbonate, calcite, the service life can be up to 2-5 years.
    High safety and reliability: Because there is no rolling bearing and no screw in the grinding chamber, there is no problem of bearing and seal damage, and there is no problem of screw loosening and destroying the machine.
    Environmental protection: The pulse dust collector is used to capture dust, and a muffler is adopted to reduce noise, ensuring clean and environment-friendly operation.

    Frequently Asked Questions

    How does the Z series micro-powder grinder operate?
    The main motor drives the spindle and turntable. Grinding rollers roll inside the ring raceway to crush materials. Crushed fine powder is carried by airflow into the powder separator, where coarse particles are returned for re-grinding, and compliant fine powder is collected and discharged.
    What makes the Z series micro-powder grinder energy efficient?
    Under the same motor power and finished product fineness, the output of the Z series micro-powder grinder is more than twice that of traditional air mills, stirring mills, and ball mills.
    What is the lifespan of the grinder's wearing parts?
    The grinding rollers and rings are made of special wear-resistant materials. The typical service life is over one year, and it can reach 2 to 5 years when processing softer materials like calcium carbonate and calcite.
    Does the machine have risk of internal parts loosening?
    No. The Z series grinder features high safety and reliability because there are no rolling bearings or screws inside the grinding chamber, eliminating the risk of bearing damage or screw loosening.
    What environmental protection features are included?
    The system is equipped with a pulse dust collector to capture fine dust effectively, and uses a muffler to reduce operating noise, complying with strict environmental protection standards.
