Which kind of grinding equipment is more suitable for rubber phosphate ore grinding

The clay content in rubber phosphate ore is relatively high, so it has a certain cementability, hence the name rubber phosphate ore.In fact, colloidal phosphate ore is a sedimentary deposit containing phosphate minerals. Its main mineral component is apatite, which is usually symbiotic with quartz, silicate minerals, clay and other minerals.For the sorting process of rubber phosphate ore, the flotation method is usually used, and after the raw ore is broken and ground, the flotation method is used to separate the phosphorus from the gangue mineral.However, its flotation effect is greatly affected by the quality of ground minerals. Below we analyze its influencing factors.

The grinding parameters of rubber phosphate ore affect the flotation effect

1. Grinding fineness

The grinding fineness of rubber phosphate ore is one of the important factors affecting the flotation effect.The fineness of flotation and grinding is different for different types of ores.Even if it is the same ore, its flotation index will be different under different grinding fineness.Therefore, ground mineral products must meet the fineness required by flotation in order to achieve the ideal flotation index.

2. Particle size distribution of abrasive mineral products

The particle size distribution of milled mineral products also has a significant impact on the selection index.The ideal particle size distribution of milled mineral products should be concentrated in the particle size range with good mineral processing indicators.This can not only improve the efficiency of mineral processing, but also reduce energy consumption and wear.

Recommended for rubber phosphate ore grinding equipment-rod grinder mill

After the above analysis, we know that the grinding effect of rubber phosphate ore and the quality of the grinding ore play a decisive role in the final flotation effect.According to the nature of rubber phosphate ore and the requirements of the flotation process for grinding mineral products, we recommend the use of a rod mill to grind rubber phosphate ore. The recommended reasons are as follows：

1. Strong adaptability: The rod mill is suitable for grinding ore with low hardness and brittleness. The hardness of rubber phosphate ore is not particularly high, and the apatite in it is more brittle. Therefore, the rod mill can adapt well to its hardness and ensure the grinding efficiency.

2. Uniform particle size of the product: The grinding effect of the rod mill is relatively mild, which can reduce the phenomenon of over-crushing, making the particle size distribution of the milled mineral products more uniform, which is conducive to subsequent flotation operations.

3. Reduce iron pollution: Compared with steel ball mills, the grinding medium used in rod mills is steel rods, which have less wear on the ore, which can reduce the pollution of the ore by the iron grinding medium, which is particularly important for rubber phosphate ore, which is sensitive to iron pollution. Ore species.

4. Low energy consumption: The grinding efficiency of the rod mill is high and the energy consumption is relatively low. For long-term mines, a lot of energy costs can be saved.

5. Grinding medium management: The grinding medium management of the rod grinder is more convenient, and the length and diameter of the steel rod can be adjusted according to the grinding needs to meet the grinding requirements of different particle sizes.

6. Improve the flotation efficiency: Since the rod mill grinds the mineral products with uniform particle size, it is conducive to improving the flotation efficiency, thereby improving the recovery rate of phosphate ore and the grade of concentrate.

The final flotation effect of rubber phosphate ore is very affected by the quality of the milled ore.Therefore, in the early stage of the design of the mineral processing scheme, mineral processing tests should be done to fully understand the properties of minerals, and grinding equipment with high grinding efficiency and uniform particle size should be selected.This can fully prepare for subsequent flotation work and make the concentrate of higher grade.
