The graded impact mill utilizes hammers, blades, rods, and other components on a high-speed rotating rotor to impact the material being crushed. Through the intense impact between the material and the rotor, high-speed collisions among the rapidly flying material particles, and the shear grinding between the rotor and the stator or side walls, it achieves the purpose of ultra-fine crushing of the material.

Working principle

A graded impact mill utilizes hammers, blades, rods, or other components on a high-speed rotating rotor to impact the material being crushed. Through the intense impact between the material and the rotor, high-speed collisions among the rapidly flying material particles, and the shear grinding between the rotor and the stator or side walls, it achieves the purpose of ultra-fine crushing of the material.

Equipment Features

◇ Suitable for materials with a Mohs hardness of3.5The following is the ultrafine grinding process for soft materials.

◇ The particle size range is finer than that of ordinary mechanical mills. The high-speed mechanical impact crusher with a built-in high-efficiency turbo classifier enables qualified fine powder to be discharged immediately after crushing, preventing over-grinding. It can produce products with a steep particle size distribution curve, with product finenessd97=10～74umAdjustable within range.

◇The crushing chamber is equipped with an automatic slag discharge device, which can automatically remove hard-to-grind particles and impurities from the material.

◇ It has the function of breaking up and dispersing agglomerated materials.

◇ High-volume airflow means cooling during grinding, making it suitable for processing heat-sensitive materials without sedimentation issues.

◇ Fully enclosed negative pressure operation, no dust pollution.
