摘要：
A particulate dispersing apparatus is provided that includes a vessel configured to contain particulate material, an insert disposed inside the vessel and having a first hole pattern and adapted to be removed from the vessel, and at least one fastener having a cylindrical body and a pair of projections extending in opposite directions from a bottom of the cylindrical body. The pair of projections are substantially perpendicular to the cylindrical body and secures the insert to the vessel. The fastener is rotatable between a securing position and an unsecuring position.
