Patent attributes
The present invention provides a protective wear cover which may be utilized in a metering device housing to protect the housing in an area which may be subjected to high impact by product flow. The protective wear cover may be installed inside the metering device housing at the venturi induction zone. The protective wear cover may be manufactured from a highly wear resistant material. The shape of the protective wear cover may be suited to conform to the metering device housing in the protected area to ensure a tight fit and negligible effect on air flow. This protective wear cover may therefore serve as a sacrificial barrier which prevents wear on the metering device housing and may be periodically replaced when worn. Replacing the protective wear cover negates the need to replace the whole metering device housing.
