A kind of superfine natural pearl powder screening device

Abstract

The invention discloses a superfine natural pearl powder screening device. The superfine natural pearl powder screening device comprises a base and a screening box. The screening box is arranged on the base; a material leakage plate is fixedly mounted in the screening box through screws; a material blocking plate is also arranged on the lower side of a feeding funnel; slide bars are horizontally welded in the screening box; and a screening groove is slidably formed between the front and back slide bars. The material blocking plate is arranged to blank quantitively at an interval; pearl powderfalls into the screening box to be screened to prevent the pearl powder from blocking the screen due to excessive pressure during screening as a result of excessive blanking at one time; the screeningbox moves left and right, so that the screening speed of the pearl powder on the screen in the screening box is accelerated, and meanwhile, the flow rate of the pearl powder on the screen is increased, and the condition that the pearl powder blocks holes is prevented; the screening box moves left and right, so that the discharge speed of the pearl powder is accelerated, the condition that the pearl powder is left in the screening box is prevented, and therefore, the superfine natural pearl powder screening device is relatively simply cleaned.

Description

technical field [0001] The invention relates to a screening device, in particular to a superfine natural pearl powder screening device. Background technique [0002] Natural pearl powder: It is produced by physical methods (such as ball milling, jet crushing and physical method ultrafine powder technology), and its characteristic is that it does not add any other substances, does not destroy any substances, and maintains all the nutrients of pearls. Pearl powder can be divided into three categories according to its particle diameter: 1. Ordinary pearl powder: the particle size is more than 200 mesh, which can meet the basic requirements of the country. [0003] 2. Ultrafine pearl powder: fineness above 1000 mesh (or particle size below 15 microns), 3. Nano pearl powder: fineness above 150,000 mesh (or below 100 nanometers), the smaller the particle size of pearl powder, the more difficult the processing technology The higher the price, the higher the price, but the finer th...

AI Technical Summary

Problems solved by technology

[0004] After the pearl powder is ground, it is necessary to sieve the pearl powder to ensure the quality of the pearl powder. When the existing pearl powder is screened, it is easy to block the holes of the screen and it is difficult to discharge.
