A rotary grinding mill for that improves the rotary grinding mill process. A milling assembly that comprise an offset ripper blades to limit the noise applied to the unit, cutting edges on the milling assembly blades, and an trailing blade edge that is angled creating a milling fan blade. The milling fan blade creates an air flow through the mill assembly. A collection container that utilized a plurality of cyclonic air flow patterns and filters to remove particles from the air. A rotary grinding mill comprising a mill housing, a hopper, and collection container, such that the grinding mill may be stored in a single unit.

A cutter assembly and high volume submersible shredder pump. These are for reducing the size of solids within a liquid which is to be pumped by chopping, grinding, shredding or cutting. An improvement over prior designs employs a cutting assembly and an associated shredder pump, wherein the cutting assembly has a centrally positioned dual sided plate cutter which engages first and second rotary cutters on alternate sides of a centrally positioned dual sided plate cutter. In operation the waste water contents have a much finer grind which improves efficient removal and reduces the likelihood of shredder pump clogging. The cutter assembly is adapted for mounting to an intake opening of a stationary volute, associated with a shredder pump. As a result, many more cutting surfaces are provided which more effectively and quickly shred the solid materials within the liquid to be expelled.

The present invention relates to an apparatus (1) for pulverizing a material. The apparatus comprises a stationary housing (3) having an interior space and at least one interior wall facing the interior space. At least one sawblade (9) is disposed in the interior space and arranged rotatable with respect to the stationary housing (3). The at least one sawblade (9) has a periphery (12) provided with a plurality of cutting teeth (15) for cutting the material and a plurality of collecting notches (17) for collecting the cut material. The apparatus comprises an inlet opening (19) for feeding material to the interior space, and an outlet opening (21) for dispatching pulverized material from the interior space. The interior wall (7) of the housing is provided with a plurality of recesses (23) facing the periphery (12) of the sawblade (9), arranged to receive the cut material from the collecting notches (17) of the sawblade (9), and to revert the cut material to the periphery (12) of the sawblade (9) so that the material will be cut multiple times before it is dispatched from the apparatus. The interior wall (7) surrounds a main part of the periphery (12) of the at least one sawblade (9), and the inlet opening (19) and the outlet opening (21) are arranged in the interior wall (7) and in direct communication with the interior space (5) so that the material enters and leaves the interior space (5) during one revolution of the at least one sawblade (9).

A grinder has a bottom with a first row of first asymmetrical blades extending from the bottom. A top of the grinder has a second row of second asymmetrical blades extending from the top. The first asymmetrical blades and second asymmetrical blades are triangle shaped. A first side of each blade has one point, and a second side of each blade has two points.
