Technical Field

[0001] The present application relates to the technical field of grading and screening equipment, and in particular to a dust-free ore grading and screening equipment. Background Art

[0002] Ore refers to a mineral aggregate from which useful components can be extracted or which itself has certain properties that can be utilized. It can be divided into metallic minerals and non-metallic minerals. The unit content of useful components (elements or minerals) in ore is called ore grade. Precious metal ores such as gold and platinum are expressed in grams per ton, and other ores are often expressed in percentages. Ore grade is often used to measure the value of ore, but the composition of gangue (useless minerals in the ore or minerals with very little useful components and cannot be utilized) and the amount of harmful impurities in the ore of the same effective ingredient also affect the value of the ore.

The reciprocating rotation of the first screen plate and the second screen plate can keep the ore on the surface of the first screen plate and the second screen plate in an active state at all times, avoiding blockage of the surfaces of the first screen plate and the second screen plate.

One end of the transmission rod 8 away from the rotating disk 7 is hinged to the bottom of the second screening plate 3. Linkage rods 9 are hinged at two opposite edges of the surface of the first screening plate 2. One end of the linkage rod 9 away from the first screening plate 2 is hinged to the second screening plate 3. By starting the servo motor 6 The servo motor 6 drives the rotating disk 7 to rotate. The rotation of the rotating disk 7 will drive the second screen plate 3 to reciprocate around the hinged edge under the action of the transmission rod 8. Under the action of the two linkage rods 9, the first screen plate 2 will be driven to reciprocate. The reciprocating rotation of the first screen plate 2 and the second screen plate 3 can keep the ore on the surface of the first screen plate 2 and the second screen plate 3 in an active state at all times, avoiding blockage on the surface of the first screen plate 2 and the second screen plate 3. The larger particles of ore on the surface of the first screen plate 2 will be discharged to the outside of the screening box 1 through the first discharge trough 4, and the smaller particles of ore on the surface of the second screen plate 3 will be discharged to the outside of the screening box 1 through the second discharge trough 5, thereby completing the grading and screening of ores of different particle sizes.
