A particle blast apparatus transport is capable of generating granular sized particles and delivering them without substantial storage to a single hose feeder assembly. The apparatus is configured to be used with solid blocks of cryogenic material, such as carbon dioxide, and with individual pellets of such material.

Apparatus and method for high flow particle blasting without particle storage

An apparatus for forming a block from carbon dioxide particle is configured to allow changing between precise thicknesses with very little downtime, utilizing both weight based and volumetric dosing. A spacer supports the lower ejection piston during block forming, with a shuttle discharging particles into the forming chamber while simultaneously pushing a previously formed block on to a conveyor. In one embodiment, the shuttle dosing cavity has a volume that is greater than the volume of the forming chamber volume, which allows more pellets, volumetrically, to be dosed into the dosing cavity than the volume of the forming cavity.
