The selection of phosphate beneficiation technology needs to comprehensively consider factors such as ore type, gangue composition and economic cost. Among them, flotation has become the mainstream process due to its high efficiency. The combination of different flotation processes and reagents can solve the problem of enrichment of low-grade and high-impurity phosphate ores in a targeted manner. 1. Selection of beneficiation methods Flotation method Direct flotation: Applicable to ...
In heavy industries such as mining, cement, and metallurgy, linings are core wear-resistant parts of crushers and ball mills, and their material properties directly affect the life and production efficiency of equipment. High manganese steel (ZGMn13) and high chromium steel (Cr20-30) are two types of mainstream lining materials, and their performance differences are significant, so they need to be selected in combination with specific working conditions. 1. Material properties and microstruct...
The ball mill is a device that grinds the material after crushing it. In detail, the ball mill performs two operations, crushing and grinding. There is a big difference in the nature of these two operations, so the ball mill must have a special structure to separate the division of labor of these two operations. This special structure is called a partition plate on the ball mill. The partition plate is crucial to the ball mill. Its function runs through the entire production process of the ball ...
