Description

Technical Field

[0001] The utility model relates to the technical field of stone processing, in particular to a grinding device for producing fine talc powder from black talc. Background Art

[0002] The main mineral in black talc is talc, which accounts for more than 92%. In addition, it contains about 5% quartz and about 2% organic matter. Talc is a magnesium-rich silicate mineral. Its main components are magnesium oxide, silicon oxide, as well as aluminum oxide, iron oxide, titanium oxide, sodium oxide and potassium oxide.

[0003] The existing patent (publication number is CN214159957U) and a grinding device for producing high-white ultrafine talc powder from black talc. This patent can put the black talc raw material into the grinding box through the feed hopper, and the first rotating rod can be rotated by the power provided by the first rotating motor. The rotation of the first rotating rod, in conjunction with the crushing blades, achieves the effect of crushing the black talc raw material, effectively avoiding the problem of large pieces in the grinding process, slowing down the work progress, and filtering the crushed black talc through the first filter screen. The filtered black talc can be scattered into the fine grinding box through the guide plate. The power provided by the second rotating motor can make the second rotating rod rotate. Through the rotation of the second rotating rod, in cooperation with the fine grinding sheet, the effect of fine grinding of the black talc is achieved. The third filter screen and the second filter screen can be used to screen the finely ground black talc, thereby avoiding the problem of slowing down the work progress during the fine grinding of the black talc. The above patent uses two sets of rotating motors, which bring about different vibration directions, which will greatly increase mechanical damage. At the same time, there is a lack of transitional structure between coarse opening and grinding, which is easy to cause structural damage to the grinding structure. In addition, the size of the black talc particles formed after coarse opening is not uniform, and it is difficult to enter the grinding structure.

[0004] Therefore, we propose a grinding device for making fine talc powder from black talc, which is conducive to using a single power source to complete the roughing and grinding operations of black talc, and is conducive to continuous grinding of black talc particles of different sizes.
