In glass industry, one of indicators for high quality glass is the ingredient homogeneity. There are two different mixing processes occurring one after another in glass production, one is the powder mixing in the mixer and another is the fluid mixing in the furnace. Both are not to be replaced by each other but equally important. Therefore, the mixing homogeneity is important indicator to verify the performance of batching system.
