Process and apparatus for compacting silver nitrate.

摘要

An apparatus and process are disclosed for forming compacted silver nitrate bodies. A slurry comprising silver nitrate crystals is introduced to a rotary screen centrifuge (78). Silver nitrate crystals are separated from the liquor and partially dried on a rotating screen (84). The separated, partially dried crystals are further dried by contact with an airstream and fall into a hopper (88). The crystals flow from the hopper into a translucent feed tube (96) and then into a roll compactor (100) that compacts the crystals to form the compacted silver nitrate bodies. An optical level detector (120, 122) monitors the level of crystals in the feed tube, and a controller (124) controls the speed of the compactor, thereby maintaining the level of crystals in the feed tube within a desired range.
