Dear Mr Anuchit,
I would like clarify some aspects regarding the environmental filters.
At the beginning of the project we had foreseen to recover the material from these filters, by means of conveyor belts of your supply.
As you can see in the different layouts, due to problems with available space, this recovery is not possible, since we would close the access to the PIG mill for maintenance operations.
So, we have foreseen the material unloading from the environmental filters into big bags. In a second moment, we can take into consideration the idea to install a recovery system with propeller.
