What are the standards and processing of oil fracturing sand?
In silica sand processing and sand washing plant , Petroleum fracturing sand is a special proppant that must be used in oil production under specific geological conditions. Is this the case with technical standards and production technology? Spherical oil fracturing sand Spherical petroleum fracturing sand is made of natural quartzite, quartz sandstone or massive quartz. Its silica content is more than 96%, Mohs hardness is more than 65, gravel diameter is greater than 14 meshes and less than 80 meshes. The crude quartz sand is processed and put into an omnidirectional grinding machine. Under the condition of adding grinding agent, it is grinded for 2-8 hours before grinding. When the material is cleaned and dried so that its moisture content reaches 8-12%, it is then transferred to the drying, separation and iron removal process. Then the polishing machine is selected to add polishing agent for polishing, and the polished material is then processed ...
