Embodiments of the invention provide a cutting blade assembly operably coupleable to a fluid pump. The cutting blade assembly comprises a cutting plate and a cutting hub. The cutting plate may have a front axial surface, an opening, and a plurality of cutting features. Each of the plurality of cutting features may define a pair of cutting edges. The cutting hub may be disposed at least partially within the opening of the cutting plate and may have a cutting arm and fin adjacent to the front axial surface. The cutting arm may define an arcuate front surface having a leading edge. When the cutting plate and the cutting hub are rotated relative to each other, the leading edge of the cutting arm may pass adjacent to the plurality of cutting features so that the relative rotation of the cutting plate and the cutting hub defines a cutting action between the cutting arm and each cutting feature.

A cutting blade assembly establishes a bidirectional and/or multifaceted scissor-type cutting action to efficiently and effectively process various types of debris encountered by the cutting blade assembly. The assembly includes a cutting plate and a cutting hub configured for relative rotation. A cutting slot is formed in the cutting plate and intersects the axial face to define a cutting edge at the intersection of the cutting slot and the axial face. The cutting hub has a cutting arm positioned adjacent to the axial face. When the cutting plate and the cutting hub undergo relative rotation, the cutting arm passes adjacent to the cutting edge to perform a scissor-type cutting action.

A mincing machine for mincing a product, in particular for mincing meat, includes at least one stationary hole plate and at least one rotating hole plate which interact to mince the product. The mincing machine has a rotating cutter head mounted on a shaft wherein said cutter head is arranged upstream of the interacting hole plates in the conveying direction of the product to be minced in order to interact with a stationary hole plate to mince the product.

The invention relates to a laboratory mill comprising at least one counter-vibration device (27) which has at least one control unit (29a) for providing a counter-vibration signal (29b) and at least one controllable vibration generation unit (29) for converting the counter-vibration signal (29b) into counter-vibrations (30), wherein the vibration-generation unit (29) counteracts a device- and/or housing part (31) of the laboratory mill (1) and the counter-vibrations (30) lead to an active reduction in the vibrations of the device- and/or housing part (31) and/or an at least partial suppression of noise-inducing vibrations of the device- and/or housing part (31), by means of destructive interference.

An apparatus for cutting polymer includes a rotor having a base with a first side and a second side opposite the first side. The rotor includes an outer annular wall extending from the first side and defining a number of slots, an inner annular wall defining a number of slots and extending from the first side and surrounded by, and spaced apart from, the outer annular wall. The rotor also includes blades extending from the first side and positioned within the inner annular wall. A circular-shaped stator also defines a number of slots. At least a portion of the stator is positioned in a space between the outer annular wall and the inner annular wall of the rotor.

A method of producing a powder suitable for additive manufacturing and/or powder metallurgy applications from a precursor particulate material comprising: subjecting the precursor particulate material to at least one high shear milling process, thereby producing a powder product having a reduced average particle size and a selected particle morphology.

Size-reduction machines, feed units, and methods capable of producing reduced-size products from a variety of solid and semisolid materials. Such machines have an impeller that rotates on an approximately horizontal axis and an opening at an axial end of the impeller. A feed unit includes a feed hopper for feeding products to an interior of the impeller through the opening of the machine, and a slicing knife is mounted to the impeller and radially protrudes across the opening of the machine to slice products into segments as they enter the interior of the impeller.

An apparatus, method and system for wet or dry processing of plant material is provided. The apparatus has an enclosure attached to a frame. The apparatus includes: (a) a cylindrical rotatable drum for receiving the plant material, the rotatable drum having a plurality of slots; (b) a cutting module for cutting portions of the plant material that pass through one or more said slots; and (c) a plurality of nozzles for ejecting a liquid within the enclosure.

The apparatus may further include a controller having a processing unit and a memory, the memory containing instructions for directing the processing unit. The controller may be operable to selectably control operations of the rotatable drum, the cutting module, and the plurality of nozzles.

The cutting module may include a plurality of cutting reels.

The cutting module and the rotatable drum may be coaxial. The cutting module may include a plurality of blades rotatable about the drum.

A foam glass aggregate slicing and reduction machine and system which rapidly, effectively, and economically reduces large pieces of aggregate to required sizes with minimal powdery waste. The machine comprises a foam glass aggregate collection chute having a bottom outlet section for discharging foam glass aggregate onto a holdbar located adjacent to the outlet section. A rotating roller supports a plurality of rotating roller knives which slices large pieces of foam glass aggregate to reduce the aggregate to fragments, with minimal powdery waste. A foam glass aggregate guide member directs foam glass aggregate towards the rotating roller. A foam glass aggregate filtering bar having rows of intervening spaces is located below the guide member and adjacent to the rotating roller.
