Abstract: An apparatus for comminuting material includes features that enable a user to alter or adjust operating parameters to optimally comminute a wide variety of materials. The apparatus includes wedges and vane tips that are removable and interchangeable with other wedges and vane tips to alter the zones of varying pressure, pressure differentials, shock waves, expansion fans, or other types of interference waves formed during operation. Temperature control systems and heat exchangers are used to independently control temperatures at different regions of the apparatus so that a user can control processing temperatures, which may vary depending on the material being processed. Corresponding methods of use are also provided.

Abstract: The present invention comprises an unloading pan for bulk dry particulate matter, such as soda ash. The pan comprises a pan inlet and a pan outlet. The pan is preferably designed wherein the source of particulate matter is a railroad car having a car outlet at the bottom to gravity unload therethrough. There is a means to position, and preferably attach, the pan container at the outlet to the source of particulate matter, i.e., the outlet of the railroad car.
