Description

Technical Field

Quartz stone is a non-metallic mineral, widely used in glass, casting, ceramics and fireproof materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives, filter materials and other industries. Quartz sand is an important industrial mineral raw material. The fine density requirements of quartz sand are different according to the needs of use. For this reason, a rolling device is needed to refine the quartz sand.

[0003] In the prior art, after the quartz sand is processed by the rolling device, the coarseness and fineness still vary. Due to the large differences in the particle distribution of the quartz sand raw material itself, and the different rolling intensity and effect distribution, it is difficult for some larger particles to be completely rolled to the expected level, so that there are still some larger particles in the rolled quartz sand mixed with relatively fine particles, which further causes some of the rolled quartz sand to not meet the specifications.

[0055] Then, the quartz sand is poured into the interior of the rough rolling mechanism 2, and the output end of the variable speed motor 23 drives the toothed transmission assembly 36 and the No. 1 toothed rolling roller 24 to rotate, and the other end of the No. 1 toothed rolling roller 24 drives the No. 1 gear 26 to rotate, and the No. 1 gear 26 drives the No. 2 gear 27 to rotate, and the No. 2 gear 27 drives the No. 2 toothed rolling roller 25 to rotate, so that the other end of the No. 2 toothed rolling roller 25 rotates on the inner wall of the No. 1 rolling box 21. With the cooperation of the No. 1 toothed rolling roller 24 and the No. 2 toothed rolling roller 25, the quartz sand entering the No. 1 rolling box 21 can be roughly rolled;

[0056] The rolled quartz sand will fall into the interior of the second rolling box 31. When the toothed transmission component 36 is in the process of moving, the toothed transmission component 36 will drive the small toothed rolling roller 2 38 to rotate, so that the other end of the small toothed rolling roller 2 38 drives the first transmission wheel 313 to rotate, and the first transmission wheel 313 drives the second transmission wheel 314 to rotate through the cooperation of the toothed transmission belt 316 and the tensioning wheel 315. The second transmission wheel 314 drives the small toothed rolling roller 1 37 to rotate, so that the two ends of the small toothed rolling roller 1 37 rotate inside the two sets of moving seats 311 respectively, thereby facilitating the small toothed rolling roller 1 37 and the small toothed rolling roller 2 38 to roll the entered quartz sand.

[0057] Finally, the crushed quartz sand will fall into the screening box 41, and the vibration motor 42 will be started. The vibration motor 42 will drive the screening box 41 and the filter screen 45 to vibrate, so that the quartz sand falling into the screening box 41 can be shaken, and the quartz sand is screened by the filter screen 45. The screened quartz sand will fall into the inclined guide plate 48 and be discharged from the second discharge box 47, while the larger quartz sand will fall into the first discharge box 46, so that the quartz sand can be screened and separated.

[0058] The screened quartz sand falls into the interior of the material guide box 54 through the tilting box 56, and then enters the interior of the feed barrel 52 through the discharge port of the material guide box 54, and the drive motor 57 is started. The output end of the drive motor 57 drives the screw shaft 53 to rotate, so that the screw shaft 53 drives the spiral blades 55 to rotate inside the feed barrel 52. The rotating spiral blades 55 will transport the quartz sand entering the interior of the feed barrel 52. When passing through the discharge port, the quartz sand falls from the spiral blades 55 and is discharged from the interior of the feed barrel 52, and then falls into the interior of the No. 1 crushing box 21, so that the quartz sand can be crushed for the second time, reducing the cumbersome steps of secondary processing of the quartz sand.
