Description

Technical Field

[0002] Ore refers to a collection of minerals from which useful components can be extracted or from which certain properties can be utilized. It can be categorized as either metallic or non-metallic. The unit content of useful components in an ore is called ore grade. Precious metal ores like gold and platinum are expressed in grams per ton, while other ores are often expressed as percentages. During ore production, the ore is crushed and screened to uniformly separate ores of varying sizes for subsequent processing.

[0003] The existing ore crushing and vibrating screening device generally achieves the ore crushing effect by stirring crushing or crushing roller crushing when crushing and screening the ore. After that, the crushed ore is screened by the vibration of the screen. However, during vibration screening, the vibration amplitude of the screen is generally small, and a tip is likely to appear during crushing. Once the tip is inserted into the screen mesh, the vibration amplitude is small, and it is difficult to vibrate the tip out of the screen mesh. If this situation occurs frequently, the screen is very likely to be blocked, thereby causing the problem of reduced effect of ore crushing and vibrating screening.

[0004] Therefore, it is necessary to design a ore crushing and vibrating screening device to solve the above problems. Utility Model Content
