BALL MILL

摘要

FIELD: machine building.SUBSTANCE: mill comprises loading (1) and unloading (2) devices, grinding balls (9) and a shaft (3) with disks (5). A hollow drum (4) is mounted on the shaft. The disks are installed on the shaft and divide the drum into sections. The disks can be moved along the shaft axis. The diameter of the disks increases from the loading device to the unloading device. A round port (6) for material loading is provided in the end face surface of the first drum section. The last drum section is fitted by ports to unload the ready product (7). Decrease of the gap between the drum surface and the disk ends allows for section-by-section grinding of material.EFFECT: invention has simple design and ensures grinding of high quality.1 dwg
