The beneficiation ratio refers to the number of tons of raw ore required for each ton of concentrate selected. Usually expressed in multiples. Its calculation formula is as follows:
The rich ore ratio is the ratio of the grade of useful minerals in the concentrate to the useful ore content in the ore, ie the concentrate grade is several times the grade of the ore. The higher the rich ratio and recovery rate, the better the beneficiation efficiency. The formula for calculating the rich ratio is as follows:
Rich ore ratios are sometimes called enrichment ratios.
The Coating Machine is suitable for coating of powder, granules, pellets, enteric release, slow and control release coating. Making use of fluid-bed technique and spray technology , low productive cost, and the coating material is used perfectly. It is particularly fit for many field such as industry, foodstuff, chemical industry. The prepared granule is porous and can solve quickly. with high sphericity, good surface luster ,certain intensity and is not easy to break. It can deal with low moisture-absorb and fluidity material to gain complete granule.
