Fiberglass is a kind of inorganic nonmetallic material with excellent performance, with a wide variety of advantages, such as good insulation, strong heat resistance, good corrosion resistance and high mechanical strength, but its disadvantages are brittleness and poor wear resistance. It is made from pyrophyllite, quartz sand, limestone, dolomite, boracite, and brucite through high-temperature melting, drawing, winding, weaving and other processes. The diameter of monofilament is from several microns to more than 20 microns, equivalent to 1/20-1/5 of a hair filament. Each bundle of fiber precursor is composed of hundreds or even thousands of monofilaments. Glass fiber is usually used as reinforcing material in composite materials, electrical insulation material, thermal insulation material, circuit substrate and other fields of national economy.

　　The working principle of the special vibrating fluidized bed dryer for glass fiber: the material enters the machine from the inlet, and under the action of the vibration force, the material is thrown forward continuously in the horizontal direction. The hot air flows upward through the fluidized bed and exchanges heat with the wet material. The wet air passes through the cyclone separator and is discharged from the exhaust port after dust removal, and the dry material is discharged from the exhaust port.

　　Features: the material is evenly heated, the heat exchange is sufficient, the drying intensity is high, and the energy saving is about 30% compared with the ordinary dryer; The vibration source is driven by a vibration motor, which features stable operation, convenient maintenance, low noise and long service life; Fluidization is stable, without dead angle and blowthrough; Good adjustability and wide adaptability; It has little damage to the surface of the material and can be used for drying fragile materials. When the material particles are irregular, it will not affect the working effect; The fully enclosed structure effectively prevents cross contamination between materials and air, and the working environment is clean.
