    .

    It is suitable for medicine, agriculture, food, chemical industry, alloy, metallurgy, geology, scientific research and other units of multiple varieties and small batches of traditional Chinese medicine, precious medicinal materials, ores, chemical raw materials such as: donkey-hide gelatin, astragalus, notoginseng, hippocampus, dodder, ganoderma lucidum, licorice, pearl All materials of different properties can be crushed very well
    .

    The equipment is used to realize the ultra-fine pulverization of dry and brittle materials by means of rolling and shearing.

    .

    The crushed material is brought out of the crushing chamber by the negative pressure air flow caused by the fan, and enters the material collection system.
    After being filtered by the filter bag, the air is discharged, and the material and dust are collected to complete the crushing
    .

    In the process of pulverization, the generation of dust is unavoidable, and a large amount of dust is inhaled by the human body and will cause harm to the body
    .

    In the process of operating the small laboratory jet mill, the following measures can be taken to reduce the harm caused by dust to the human body: (1) Due to the slight leakage of dust in the manufacturing process, dust will emerge, causing pollution in the work area.

    .

    Therefore, the tightness of the joint should be ensured
