The invention discloses a crushing, screening and
magnetic separation device for high-purity
quartz powder, and belongs to the technical field of
quartz processing. The device comprises a shell, the lower surface of the shell is fixedly connected with the upper surface of a filter component, and the inner surface of the filter component is provided with a
magnetic separation structure and a firstfilter structure. The first filter structure is located below the
magnetic separation structure, and the lower surface of the first filter structure is slidably connected with a second filter structure. According to the crushing, screening and magnetic separation device for the high-purity
quartz powder, by arranging the first filter structure, the second filter structure and an adjusting piece, when crushed quartz needs to be screened and screening holes are blocked, the second filter structure is adjusted to move leftwards and rightwards by rotating the adjusting piece, and therefore the sizes of the screening holes are adjusted to prevent blockage; and three groups of first filter structures and second filter structures are arranged for screening for multiple times, so that the accuracyof the
diameter of quartz particles is improved, and the quality of later processed products is improved.
