Description

Technical Field

[0001] The invention relates to the technical field of mining, in particular to ore crushing equipment for mining. Background Art

[0002] Ore refers to a mineral aggregate from which useful components can be extracted or which has certain properties that can be utilized. It can be divided into metal minerals and non-metallic minerals. The unit content of useful elements or minerals in the ore is called the 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 refers to a stone containing some valuable minerals mined from a mine. After being processed step by step such as crushing and grinding, the ore can be used in engineering fields such as metal mines, metallurgical industry, chemical industry, construction industry, railway and highway construction units, cement industry, and sand and gravel industry.
