Foam Glass Production Line

Adopting glass powder (silica sand, quartz stone or broken glass are usually applied) as the main raw material, and mixed with a proper amount of additives, the foam glass production line adopts “the powder two-step burning method” which is famous all over the world. The main process flow is as followed: raw material collecting, washing, drying, material mixing and grinding, moulding, sintering, foaming, stabilizing, de-moulding, annealing, cutting and product processing.
