Description

A high-efficiency ore crusher with iron removal device

technical field

The utility model relates to a mechanical device, in particular to a high-efficiency ore crusher with an iron removing device.

Background technique

Ore refers to mineral aggregates from which useful components can be extracted or which have 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 usually expressed in percentages. The ore grade is often used to measure the value of ore, but the composition and harmful impurities of the gangue (useless minerals in the ore or minerals with very little useful content that cannot be used) and the amount of harmful impurities in the ore also affect the value of the ore. Ore crushers can be widely used in mining, smelting, building materials, roads, railways, water conservancy and chemical industries and many other sectors. Its purpose is to break larger ores into smaller pieces that meet the requirements. Existing ore crushers generally have the disadvantages of poor crushing effect and low work efficiency, and cannot effectively remove dust, nor can they effectively screen ore, and cannot meet the needs of modern ore processing.
