energy cost of producing basalt
energy cost of producing basalt : Basalt Continuous Fiber (BCF) production techniques. The basalt raw material is reduced to fractures 5 ~ 20 mm in dimension the basalt fractions are fed by the charging conveyer (1) to the melting furnace (2) the charged basalt is melting at a temperature of 1400 ~1600 #176;C the melted basalt passes through the die holes of the bushing (3
