Use of Economic Mineral Hydraulic Mining Technology for Expanding the Raw Material Base for Refractory Manufacture

详细

The problem is considered of including in the raw material base for manufacturing the main refractory products hydraulically mined economic minerals (quartzite, sandstone, refractory clay, kaolin, bauxite, sillimanite, serpentinite, bischofite, etc.). It is noted that the specific nature of hydraulic mining gives rise to the possibility of comprehensive use of natural raw material components and simplified preliminary preparation technology for use within the composition of refractory objects. A mechanized hydraulic device is proposed for mining economic minerals, effective for enriching and classifying sand and clay mixtures in flooded sand, and sand and gravel deposits.
