When manufacturing glassware or glass containers, crushed or recycled glass, or cullet, is an additional key ingredient. The amount of cullet used in the batch house of glass varies. And the manufacturing process of the glass container or glassware is a continuous process, so the batching processes will also occur constantly. The raw materials of soda lime glass will be then gravity fed into the weighing and mixing area, and finally elevated into batch hoppers that supply the glass furnaces. Sometimes the conveyor belt consists of a magnet that will remove the magnetic materials to ensure the composition of the material will be the same for all the processes. Cullet melts at a lower temperature which reduces energy consumption and requires fewer raw materials.
