FIELD: oil and gas industry.
SUBSTANCE: invention refers to oil and gas industry, and namely to the manufacturing procedure of ceramic proppants intended to be used as propping agents at production of oil or gas using hydraulic fracturing method. The manufacturing procedure of magnesian-quartz proppants includes treatment of the stock, wet milling, granulating and annealing of granules. Wet milling is made in a ball crusher charged with a mix of metal grinding bodies and grinding bodies made of the stock used for production of magnesian-quartz proppants with the following ratio of charged components, wt %: metal grinding bodies 37-55, mill feed 26-30, magnesian-quartz grinding bodies 37-15, at that coefficient of the crusher charge is equal to 0.48-0.55.
EFFECT: reducing breakability of proppant granules due to improved quality of the stock milling.
