A device for comminuting feed material with first comminuting tools and second comminuting tools, which are arranged inside a housing coaxially to an axis and which are axially spaced apart to form a comminuting zone, and of which at least the first comminuting tools perform a rotational movement about the axis. In a contact area between a first tool carrier and the first comminuting tools and/or in a contact area between a second tool carrier and the second comminuting tools a plurality of channels for the passage of a process gas are provided. The channels each have a radially inner inlet opening through which the process gas enters the channels and a radially outer outlet opening through which the process gas emerges from the channels. Among other things, this achieves improved cooling of the comminuting zone.

An improved grinding mill that utilizes mill stones that minimizing the mechanical processes required to regulating the mill stones and allow an user to gain quick and easy access to the mill stones by removing a hopper. In addition, to provide a base frame for the mill that secures both mechanical and electrical parts including the mill housing to reduce manufacture and repair time.

Disclosed is an assembly for use in an herb vaporizer. The assembly includes a casing having at least one casing air passageway. The assembly also includes a first grinding element partially defining a grinding chamber and a second grinding element, opposed to said first grinding element, further defining the grinding chamber and rotatably mounted such that contents of the grinding chamber are agitated by rotation of the second grinding element. The assembly also includes a heater within the casing operatively associated with the grinding chamber, and being electrically coupled to a threaded connector providing an electric connection from a battery unit. The threaded connector projects from the casing for mating with an external battery unit.

An apparatus for recycling synthetic thermoplastic waste material combining heretofore multiple stage processing steps in a single stage shredder grinder pulverizer device. The apparatus has multiple interchangeable material processing blade sets on respective effacing engageable rotating and fixed blade mounts within a cooled material infeed and blade containment enclosure with multiple vacuum outlet ports and communicating vacuum ducts to draw off and transport processed material therefrom for separation and classification, as required. Each replaceable interchangeable processing blade set includes registerable shredding and grinding blades and annular pulverizing blade sets on fixed and movable mediums for progressive processing of waste material into uniform recyclable material.
