Description

Technical Field

[0001] This utility model belongs to the field of quartz sand crushing technology, specifically relating to a crushing device for producing high-purity quartz sand. Background Technology

[0002] With the rapid development of science and technology and industry, high-purity quartz sand has become an irreplaceable key mineral raw material in high-tech fields such as new energy solar energy, optical fibers, information technology, lasers, aerospace, and national defense. However, quartz ore has a high impurity content, with more low-grade ore and less high-grade quartz ore; high-grade quartz ore is even rarer.

[0003] Traditional quartz sand processing methods often fail to meet the production requirements of high-purity quartz sand, and their ability to remove impurities is limited. Currently, the mechanical crushing methods generally used can only crush large quartz sand particles into smaller particles. However, further small-batch crushing and processing still requires manual grinding. Therefore, we propose a crushing device for high-purity quartz sand production to solve the above-mentioned problems. Utility Model Content

An upper grinding disc 46 is fixedly installed at the bottom of the connecting pipe 43, and the bottom of the upper grinding disc 46 is in contact with the top of the grinding seat 5.

[0028] In this embodiment, a first positioning hole 42 is provided on the rotating rod 41, and a plurality of second positioning holes 44 are provided on the connecting pipe 43 to cooperate with the first positioning hole 42. A positioning rod 45 is inserted into one of the second positioning holes 44, and the positioning rod 45 passes through the second positioning hole 44 and engages with the first positioning hole 42 on the rotating rod 41.

[0029] In this embodiment, the grinding base 5 includes a lower grinding disc 51. Three hydraulic rods 53 are provided at the bottom of the lower grinding disc 51.
