Abstract

The invention discloses a circulating type powder grinding device which comprises a body provided with a powder grinding chamber, hoppers arranged on the upper part of the body, and grinding mechanisms; the grinding mechanisms comprise a coarse grinding mechanism and a fine grinding mechanism, wherein the coarse grinding mechanism is arranged inside the powder grinding chamber of the body, the bottom of the body is provided with a filtering device with mesh pores, and the fine grinding mechanism is arranged below the filtering device. The circulating type powder grinding device also comprises a debris recovery mechanism which is used for transporting debris on the filtering device and with the particle size greater than the mesh pores to the upward side of the coarse grinding mechanism; the coarse grinding mechanism comprises two pairs of mutually symmetrically arranged roller mechanisms, wherein the interior of the body is provided with guide plates for respectively guiding raw materials to the upward sides of corresponding rollers; the fine grinding mechanism comprises a group of paired-arrangement columnar rollers, wherein a gap between the adjacent columnar rollers is adjustable; the fine grinding mechanism also comprises elastic tensioning devices each for adjusting the gap between the adjacent columnar rollers. The circulating type powder grinding device has the characteristics of full grinding, low energy consumption, and simple control.

Description

technical field [0001] The invention relates to a milling device for grinding granular materials into powder, in particular to a circulating high-precision milling device with processes such as cutting, impacting, rolling and grinding. Background technique [0002] Existing particle milling devices, such as pearl milling machines, mostly adopt the principle of impact crushing, but only have the function of fine crushing and coarse grinding, and cannot effectively ensure that the pearl shavings after impact can be turned into powder. The pearl powder and pearl shavings are mixed; at the same time, the traditional water-flying method of grinding pearls also takes a long time due to repeated precipitation and suspension of pearl particles in water, and the grinding structure used in the later stage is also relatively simple, which cannot Ensure adequate grinding. [0003] Among the existing general mechanical milling devices, although most milling devices use roller milling, t...
