What is Discharge Cross Contamination?
Discharge Cross Contamination occurs in Silos and Hoppers when fresh material is mixed with older material. Even the smallest contamination can result in loss of product, which can be a great inconvenience for sites.Discharge Cross Contamination ultimately reduces the volume of fresh product that a silo can hold and may eventually make it unusable. Troublesome material such as polyester pellets can form soft clumps over a silo outlet and result in bridging or ratholing.
The issues can result in loss of product and downtime on site due to having to manually clean the silo and empty the content. Therefore, regular and professional silo cleaning is essential if the buildup of product residue on the internal vessel walls is to be prevented.
Installing a Primasonics Acoustic Cleaner just above the silo outlet is one solution to the issue. This would prevent any material from building up in the hopper area, thus preventing silo discharge cross contamination.
