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.

A mill housing of a pulverizer system. The mill housing may include a cutting chamber, and a plurality of air intake holes configured to introduce airflow into and in a direction tangential to the cutting chamber. The plurality of air intake holes may include two or more single air intake holes, two or more single air intake slots, or one or more groupings of air intake holes, spaced evenly around an exterior surface of the mill housing. Each of the one or more groupings of air intake holes may include two or more vertically aligned air intake holes. The holes, slots, or groupings of holes may be machined into the mill housing exterior at an angle so as to allow the intake of air to enter the mill housing tangentially to the circumference of the cutting chamber, resulting in a more polished particulate having a higher density and increased flowability.

A rotary processing device that processes a processing object inside a drum and suppresses scattering of particles is described. The rotary processing device includes a drum including a feeding unit for the processing object on one side and a discharge unit for the processing object on the other side and a processor that is connected to a rotation axis member, rotates about a rotation axis of the rotation axis member, and processes the processing object in the drum. The rotary processing device also includes a suppressor that suppresses a gas flow from the other side toward the one side in the drum.
