Lump Breaker

The Oyster™ Hygienic In-line Lumpbreaker is the ideal solution for breaking up lumps that can form in bulk powders and other solid products during storage or transport.


In the Pharmaceutical and Food industries especially, the presence of these agglomerations in the product will seriously disrupt subsequent handling and processing operations if they are not dealt with effectively. The use of the Lumpbreaker enables the user therefore to improve product quality, and reduce downtime in downstream processes.

The Oyster™ Hygienic Lumpbreaker is suitable for installation in discharge and tipping stations and also in loading pipes, to clear lumps prior to pneumatic transfer etc.
