Quartz powder production technology introduced

According to the final use of the product needs to determine the appropriate and suitable purity quartz particulate material , you can make quartz powder ( silica ) grinding .
Basically, the abrasive quartz powder, a wet and dry in two ways , namely wet blended with a certain proportion of the raw materials in water ( if the product is of high purity , deionized water can be used ) , in a grinding machine , then use the water classification ( sub granularity ) , drying process .
This method had previously been used as a wider range of silica processing methods , but because of its need to consume a lot of water , emit large quantities of contaminated water and waste a lot of heat drying , water classification accuracy is relatively low granularity , use is also dwindling .
Currently, only a small part of the requirements of the electronics industry requires a special use of such products.
Dry grinding currently used more widely , and there is more and more increasing trend . The basic approach is to choose a suitable grinding media for grinding and sieving or air classification granularity ( sub granularity ) . In this way , environmental economy , and the exact size air classification , the only shortcoming is that the composition of the wear of grinding media , the product will be a small increase in its ingredients. So choose a highly efficient grinding effect , low wear and, as a small amount of impurities contained in the product acceptable for most industries grinding media are particularly important .
Currently, a large industry proved corundum alumina ( main component of 95% Al2O3, other minor components mainly SiO2) is the most suitable grinding media . Various industries, basically acceptable use of alumina corundum abrasive silica products.
Silicon micro- grinding equipment selection , there are a variety of grinding equipment, a rod mill , cone mill, Raymond machine, but because of its inevitably bring products in the processing of a large number of Fe2O3 content , it can only for the production of building materials, refractory and other industries low demand quartz powder .
Electronics, chemicals , paint and other industries generally use the ball mill, jet mill , but it can be a huge airflow wear suitable only for 2500 mesh products with fine , so far the most widely used is the ball . May be wet , but also for dry -type , for the continuous production , but also for the production batches . Wherein the abrasive media can also choose to select the previously mentioned alumina corundum, quartz can also choose to block itself can also be used with both .
It can also be controlled with air classifier granularity control the final product , is currently the most widely used in the production of silica as a reasonable solution .
