GRINDING APPARATUS FOR NUCLEAR FUEL PELLETS

摘要

Particulates (42) from a source (12) fall into a tundish (14) which discharges to a collection chamber (18). The build-up of particulates (42) in the chamber (18) is sensed, and a valve (22) opened at the bottom of the chamber (18) when a pre-determined level of the particulates (42) is sensed in the chamber (18). A valve (17) at the top of the chamber (18) may be closed at the same time so that pressurized air can be injected into the chamber (18) to expel the particulates (42) through the bottom of the chamber (18) through the valve (17). A filter circuit (52) may be connected to the tundish (14) to assist in removing particulates (42) from the tundish (14).
