更多关于擦洗
Deleterious materials are not as strong as aggregates 和 minerals. They can degrade quickly, causing a loss of support in the pavement or structure. 因此, desirable aggregates 和 minerals should be clean 和 free of impurities that can cause problems that affect their performance.
例如, lumps of clay present in aggregate that is intended for cement or asphalt can cause bonding issues, creating weaknesses in the structure 和 affecting durability 和 wear, as well as other problems. Because clay can absorb water, its presence in rock intended for concrete can increase the amount of water required to mix the materials. Clay can also decrease the permeability of a final product intended for drainage or the release of natural gas, as clay fills in the voids needed for the water to drain or the gas to escape.
Since the value of minerals is dependent on their quality, clay 和 other deleterious materials need to be removed at the processing plant prior to the downstream process. Sometimes these impurities can be removed by washing, but other times a more aggressive approach is required to work the deleterious material free.
Deleterious materials that can’t be removed with just washing need to be scrubbed in order to be released. 擦洗 is more intense 和 requires more energy than washing. During the scrubbing process, 矿物质被释放, 或分居, from deleterious materials by agitation with water 和 then thoroughly flushed away from the desired product to a settling pond or water treatment process.
Most scrubbing action occurs through material-on-material attrition created by the violent agitation of a drum or rotating paddles on a shaft. As the material turns on itself, creating a scrubbing action, the deleterious material is separated 和 the desirable products are moved to the next part of the wet processing system. 擦洗 is required to produce a high-quality, silt-free aggregate or mineral product that meets the specifications outlined in the contract with the customer. Efficiently removing the clay 和 other deleterious materials increases the value of the final product.
