Glass wool production line Glass Fiber production line


Glass wool production line  Glass Fiber production line picture The raw materials for making glass wool include scrap sheet glass, silica sand, feldspar, limestone, dolomite, soda ash, salt cake, borax, etc., which can be selected depending on local resources.
Qualified raw materials based on chemical analyses are separately weighed and homogeneously mixed according to the batch formula, and then sent to the furnace bin.
Mixed powder materials (batch) are uniformly fed into the furnace by a batch charger. The batch is melted by electrical heating in the furnace and homogenized in the refining zone to become homogeneous boron-containing molten glass and then flows to the forehearth.
Molten glass flows through the forehearth to the bushings made of Pt/Rd alloy and kept at constant temperature, from which continuous and stable glass streams flow out and fall down into the spinner. The spinner rotates at high speed and forces molten glass out of the small holes in the sidewall of the spinner by centrifugal force to form primary fibers, which are then attenuated into glass wool by the high temperature and high velocity flame blown from the circular gap of annular burners mounted around the spinner. The jet flame from the burners not only attenuate the fibers, but also maintain the temperature required for the spinner ......
