Once the mix has been prepared, it is discharged to be taken to a storage silo from where the distribution happens. As far as the capacity is concerned, you can buy small-sized plants with a capacity of just a few tons per hour but if you are a big operation, you can also buy giant plants that are capable of delivering more than 600 tons per hour.
