Sintering | Eurotherm Limited
Figure 1 shows a simplified diagram of a sinter plant. Materials enter the sinter plant from storage bins. They are mixed in the correct proportions using weigh hoppers, one per storage bin, except for the return fines for which an impact meter is used instead. Weighing is continuous, as is the whole sintering process.
