    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, greatly improving utilization. Generally up to more than one year; processing calcium carbonate and calcite, service life can reach 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, nor screw loosening to destroy the machine.
    Environmental protection: The pulse dust collector captures dust and the muffler reduces noise, ensuring excellent environmental protection compliance.

    Frequently Asked Questions

    Q What is the working principle of the Z series micro-powder grinder?
    The main motor drives the spindle and turntable to rotate. The grinding rollers roll within the ring raceway, crushing the material scattered by centrifugal force. A high-pressure fan then draws the fine powder into a separator, where qualified fine powder is collected and coarse particles return for re-grinding.
    Q How energy-efficient is the Z series micro-powder grinder compared to other mills?
    With the same finished product fineness and motor power, the output of the Z series micro-powder grinder is more than twice that of traditional air mills, stirring mills, and ball mills.
    Q What is the expected service life of the wearing parts?
    The grinding roller and grinding ring are made of special materials. Their service life is generally over one year, and can reach 2 to 5 years when processing materials like calcium carbonate and calcite.
    Q Why is the Z series grinder considered highly reliable and safe?
    The grinding chamber contains no rolling bearings or screws. This design eliminates common failure points such as bearing or seal damage and loose screws that could damage the machine.
    Q What is the output capacity and final product size of these grinders?
    The Z series grinders produce a final product size of 5 to 47 microns. The capacities vary by model: Z-80 produces 0.4-4.5 T/h, Z-100 produces 0.7-7.5 T/h, and Z-125 produces 1.5-12 T/h.
