Description

Technical Field

[0001] The utility model belongs to the technical field of ore crushing, and specifically relates to an ore crushing device. Background Art

[0002] Ore refers to a mineral aggregate from which useful components can be extracted or which itself has certain utilizable properties. 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 commonly expressed in percentages. Ore grade is commonly used to measure the value of ore, but the composition of gangue (useless minerals in ore or minerals with very low content of useful components that cannot be utilized) and the amount of harmful impurities in ores with the same effective components also affect the value of ore.

[0003] During the processing of ore, it is necessary to crush some medium-sized ores. Existing ore crushing devices often use a crushing hammer to hammer and crush the ore. This method is not convenient for controlling the size of the crushed ore according to different usage needs, has a poor crushing effect, and often generates a large amount of dust, causing environmental pollution. For this reason, we propose an ore crushing device. Summary of the Utility Model
