Increased Flexibility for Cement Plants with new Storage Feeder System

Samson Feeder from Aumund in New Operation
The Samson feeder has found an additional application as surface storage feeder SSF, thus making operations of a cement mill much less complex and much more cost effective. It adds increased flexibility in handling different materials and in adapting the plant layout to changing production demands.

Quick reaction to changing demand and changing short-term fuel or raw-material costs is the most decisive factor to a profitable plant operation in the modern cement industry. However, a production process involving deep pits, bunkers or bins demands the construction of massive foundations and a geography, where it is possible to dig deep down. A quick relocation of the machinery due to changing production processes or evolving market situations is impossible. Flexibility remains rather limited.

As it turns out however, the cement industry rarely needs the vast buffer storage provided by bunkers and bins. The storage capacity provided by a surface storage feeder (SSF) like the Samson feeder has proven to be fully sufficient. It is surface mounted without the need for special foundations and it can be relocated rather easily within the plant or even between sites, should the need arise. Furthermore the SSF can handle materials of different consistency from cohesive and sticky to abrasive and beyond. It can be supplied in virtually any size and length to build a buffer capacity based on the plant’s needs.

SSF in Operation

The SSF receives material directly from either rear tipping trucks or front end loaders. The entry section provides a certain storage capacity within the unit itself for initial material receiving with quick vehicle turnaround times. Total storage capacity depends upon the application, material density, feed rate and size of the unit. The SSF keeps a constant level of material within its head chute which is then extracted at an either constant or variable rate by means of a weigh feeder, weighing belt or a similar device.
