Description

Technical Field

[0001] The utility model relates to the technical field of fluorite feeding, in particular to a crushing and feeding device for fluorite mining. Background Art

[0002] Fluorspar crushing and loading refers to the process of crushing and loading fluorspar ore for further processing and utilization.

[0003] Fluorite, also known as fluorspar, is a common mineral primarily composed of calcium fluoride. It crystallizes in the isometric system, forming octahedrons and cubes. It has a vitreous luster, vibrant and varied colors, and is brittle. It has a Mohs hardness of 4, a melting point of 1360°C, and exhibits a perfect cleavage of 2.

[0004] The existing patent publication number is CN214568301U, which discloses a feeding device for fluorite mining, including an oblique upward conveying platform, characterized in that: the conveying platform includes a conveyor belt, and a number of partition plates are vertically installed on the conveyor belt, and the adjacent partition plates have the same spacing. The cross-section of the partition plate is a trapezoidal structure, and there is a threaded hole passing through it near the bottom. The feeding device for fluorite mining inserts the partition plate into the groove, and the threaded hole and the through hole just fit together. Bolts are inserted through the through hole and extend into the inside of the threaded hole. The bolt connection allows for easy disassembly. When encountering fluorite ore with a larger diameter, the middle partition plate can be removed to increase the spacing between adjacent partition plates. In addition, due to the heavy weight of the fluorite ore itself, the partition plate is easily worn during upward transmission. If it is severely worn, it can be replaced.

[0005] The existing feeding device used in fluorite mining suffers from excessive fluorite loading during crushing, which causes the crushing device to be overloaded during crushing, making it difficult to crush the fluorite completely and affecting crushing efficiency. To address this issue, we propose a crushing and feeding device for fluorite mining to solve the above-mentioned problem. Utility Model Content
