Glass powder sorted out by the powder sifter and two types of foaming materials are automatically measured and mixed. These materials. which are different in quantity, specific gavity and shape, are thus uniformly mixed.
The mixing machine is of sequential batch type and can produce 350 kg of powder mixture in a batch process. In addition, the whole process of feeding, measuring and adding the two types of foaming materials is fully automated, allowing the stable production of glass powder mixture in uniform quality.
