Glass Manufacturing Plant

Float glass manufacturing is not unlike the manufacturing of commodities like steel or plastic. Each of the processes requires raw materials to be weighed, mixed, melted at high temperatures, formed into continuous ribbons, cooled and cut into a size that fits its use.Float glass is made from a combination of several ingredients such as sand, soda ash, dolomite, limestone,salt cake, and cullet (recycled glass).The raw materials are received and stocked in storage areas. From storage areas they are then moved as needed to the silos. The raw materials are then drawn down from the silos for batch weighing and mixing. Cullet, which is crushed glass from edge trim of the cut lites or from broken cut lites, is blended with the mixed batch to make from up from 15% to 30% of each batch. The mixture is then delivered to the melting furnace by belt conveyor.
