The integration of different types stone washing machine

The ore preparation process of hydrosmelting is mainly ore washing and chromium removal. The raw ore is mainly low-grade limonite or mixed ore mixed with residual ore, which has the characteristics of high moisture content, high viscosity, and complex process. The washing equipment used in the laterite nickel ore washing process mainly includes roller screens, cylinder washers, cylinder scrubbers, trough washers, etc. However, some mines have begun to add MMD crushing before washing. Machine crushing to reduce wear and tear on the equipment after larger particles enter the ore washing equipment. The chromium removal equipment currently used is mainly hydrocyclone, spiral chute, shaker, etc. Due to the fine particle size of laterite ore, it is difficult for the material to settle. Therefore, high-efficiency concentrators are generally used for laterite ore slurry concentration. Some mines also use deep cone concentrators for…

This method uses high-purity quartz sand as raw material to produce solar-grade polysilicon. Select silica materials with a SiO2 content of more than 99%, and perform water quenching, crushing, screening, pickling, magnetic separation, and high-pressure ionization to make the purity of the silica particles reach 99.99. % or more to obtain high-purity quartz sand. Chloride the carbonaceous reducing agent and the graphite electrode in the submerged arc furnace at high temperature in the chlorination furnace to make the purity of the carbonaceous reducing agent reach more than 99.9999%; use carbon in the submerged arc furnace High-purity quartz sand is reduced with a high-quality reducing agent to produce silicon. During the production process, silicon liquid is regularly released from the submerged furnace; the obtained silicon liquid is injected into the holding furnace, and the product is directly subjected to high-frequency plasma…

The sewage produced by washing fluorite contains only about 5% mud, but it is difficult to settle. Please tell me why. After fluorite is mined, because a lot of crushed fluorite is mixed with the mud on the mountain, it needs to be cleaned. However, after washing fluorite The sewage is difficult to settle, and the mud content of the sewage is only about 5%. With PAM and PAC added, the maximum sedimentation speed is only 0.021mm/s; it is 4 times more difficult to settle than fluorite flotation sewage. What is this? Please tell me why. Is there any good solution? Solution: It may be that you added too much PAC. Excessive PAC will produce too many small flocculent alum flowers, which are not easy to settle. I suggest you find a few bottles for experiments, add PAC first and…

Trough-shaped hydraulic classifiers include hydraulic classification boxes and KP-4C hydraulic classifiers. It is mainly used for grading operations before gravity selection of the ore dressing shaker to meet the requirements of the shaker's ore particle size, ore feed volume and concentration. The hydraulic classification box is a free-settling classification equipment, suitable for processing materials with smaller particle size and higher fine mud content. The suitable classification particle size is 2-0.074mm, and the ore concentration is 18%-25%. When processing materials with high density and coarse particle size, the water consumption is larger than that of the interference sedimentation hydraulic classifier, the discharge pipe is easily blocked, and the classification effect is poor; when the classification particle size is less than 0.074mm, the classification effect is also poor. The advantages of trough hydraulic classifier equipment are simple structure, no need for power…
