A smoking accessory assembly facilitates storing and transporting accessories for grinding smoking matter and rolling the smoking matter for smoking. The assembly includes a housing having a plurality of compartments. A grinder has a plurality of grinder teeth and a peripheral wall enclosing the grinder teeth. A plurality of cap teeth is coupled to and extends from a top cap. The grinder is insertable into the top cap for grinding plant matter. A funnel tapers away to a tube section extending from a base of the funnel. Openings extend through the grinder for passing ground plant matter through the funnel and into the tube section. The tube section is open for passing the ground plant matter into a rolling paper wrapped around the tube section.

A container when assembled includes a body, a cover, a lower grinding component, and an upper grinding component. The body includes a primary storage area compartment, the lower grinding component includes a grinding area compartment, and the upper grinding component includes a secondary storage area compartment. The upper grinding component partially nests within the lower grinding component. The lower grinding component defines a recess comprising the grinding area compartment. The upper grinding component is inserted into and partially received within the recess of the lower grinding component to form a grinder. The lower grinding component partially nests within the body of the container and the cover fits over the upper grinding component and partially over the lower grinding component when the cover is secured to the body of the grinder, whereby the grinder is completely enclosed within the body and cover of the container.

Disclosed is an apparatus for the processing of plastics, with a container with a rotatable mixing, where, in a side wall, an aperture is formed, where a conveyor is provided, with a screw rotating in a housing, wherein the imaginary continuation of the longitudinal axis of the conveyor in a direction opposite to the direction of conveying passes the axis of rotation, and wherein the ratio (V) of the active container volume (SV) to the feed volume (BV) of the container or of the cutter compactor (1), where V=SV/BV, is one where 4?V?30, where the active container volume (SV) is defined by the formula $\mathrm{SV}=D^3\frac{?}{4}$
and D is the internal diameter of the container, and where the feed volume (BV) is defined by the formula $\mathrm{BV}=D^2\frac{?}{4}.Math.H,$
where H is the height of the intake aperture.
