In many instances bulk storage facilities are used to supply materials to internal intermediate storage hoppers or 'day bins'. These day bins are then utilised to feed a specific process or plant operation. Such systems generally provide automatic refilling of the intermediate storage hoppers either pneumatically or mechanically.

Intermediate storage facilities can be manufactured from both mild and stainless steel and include level detection and monitoring systems. Such storage facilities can be supplied to accommodate any required capacity and suit any specific downstream throughput via automated discharge valves and feeding devices.

Pneumatically fed hoppers are generally supplied with a reverse jet filter unit to remove transferred product from transferring air without expulsion of dust to atmosphere.
