Lahti Precision has developed a completely pneumatic batch Plant for reinforced fiber glass production. The development is based on Lahti’s patented fluidization technology used in the drymix plants supplier by us worldwide. Traditional screw feeders are replaced with air slides and double dosing valves. The only moving part is the dosing valve. Mixing takes place by a pneumatic blender-transporter as well as batch transport to the furnace silo.
