A method, a system and devices are for processing of at least one substance into a dried, fragmented and fluidized end product. The at least one substance is delivered in fragmented state from a fragmenting device to a fluidizing, drying and filtering unit. The at least one fragmented substance is subjected to fluidizing action from at least one set of rotary shovels while blowing a drying agent (DA), e.g. hot gas, hot air, vapor or superheated steam into a space of the unit. The drying agent, having passed through fluidized, fragmented substance(s), is sucked and filtered to let it exit a space at an upper end or lateral region thereof. Further, the fragmented, fluidized and dried substance(s) are caused to leave the space at a lower region thereof as the product. Humid drying agent exiting the space is at least partly de-hydrated and/or heated before re-entering the space.

A tree stump grinding wheel assembly includes a rotor having a plurality of holders distributed about its cutting periphery. Each holder has a neck in which resides a socket adapted to receive the shank of an indexable tooth. A head is attached to one end of the shank and screw threads are formed in its other end. The head has a plurality of flats configured to sequentially register with a forward shoulder on the neck. A hermetic spring is operatively disposed on the shank between a rearward face of the socket and a retention nut. The hermetic spring is made of elastomeric material and has a tapered nose that self-seats in a countersink at the rearward opening of the socket. The hermetic spring has an accordion-like bellows section. The bellows section can have a central annular bulge.

A bone grinder is provided herein. The bone grinder may have a grinding chamber, an intermediate zone, and a primary cutting element and a secondary cutting element. The intermediate zone may have a first wall and a second wall within the grinding chamber, and the intermediate zone may separate the primary cutting element from the secondary cutting element. The first wall and the second wall may slope inward such that a distance between the first wall and the second wall generally decreases from the primary cutting element to the secondary cutting element. The primary cutting element and the secondary cutting element may be positioned within the grinding chamber to sequentially perform primary cutting operations and secondary cutting operations on a bone. A drive mechanism may operatively engage the primary cutting element and the secondary cutting element.

Biomass feedstocks (e.g., plant biomass, animal biomass, and municipal waste biomass) are processed to produce useful products, such as fuels. For example, systems are described that can convert feedstock materials to a sugar solution, which can then be fermented to produce a product such as a biofuel.

A waste processing machine for reducing waste material and having a safety device for shearing lines. A housing defines a cutting chamber and an intake opening in communication with the cutting chamber for receiving waste material. A disc is disposed in the cutting chamber, rotates about an axis, and has an axial surface facing the intake opening. A cutting member is fixed to the disc for revolution about the axis concurrent with rotation of the disc for reducing waste material. A cutting anvil is coupled to the housing adjacent to the intake opening and faces the axial surface of the disc for reducing waste material between the cutting anvil and the cutting member. A line shear element is attached to the housing, extends into the cutting chamber toward the axial surface of the disc, and is spaced from the cutting anvil for shearing lines caught by the rotating disc.

Disclosed herein are devices for micronizing an aspirate. Also disclosed herein are systems for micronizing an aspirate. The devices and systems may include a liposuction syringe for liquefying fat and/or an incubator for expansion of cells. Devices and systems may also include a handpiece with a handle, a motor disposed within the handle, a blade positionable within a syringe barrel containing an aspirate, the blade rotationally coupled to the motor by a drive shaft, and an end cap positioned along the drive shaft between the blade and the handle, the end cap including an opening through which the drive shaft extends, the end cap configured to seal the syringe barrel.

The system for separating battery cell cores includes a cell core holder for receiving and holding a battery cell core. A cutter cuts an outer wrapping layer of the battery cell core to form an open loose end. A first roller rotates the battery cell core and a sheet opener engages the open loose end to unroll a laminate, which includes a cathode layer, an anode layer, and a polymer separator layer sandwiched therebetween. A pair of second rollers receive, grip and selectively drive movement of the laminate. A cathode breaker applies breaking force to the cathode layer to produce broken cathode layer pieces, which are then collected. An anode breaker then grasps and vibrates the laminate to produce broken anode layer pieces, which are also collected. Finally, a polymer separator layer cutter selectively cuts the polymer separator layer to produce cut polymer separator layer pieces, which are collected.

Screens for conical mills and an improved gearbox and housing for such conical mills are shown and described. The screens are frusto-conically-shaped and include a tapered sidewall with a plurality of openings in the sidewall that may be of uniform size. Each opening is separated from adjacent openings by spacing distances which are shorter at the top of the tapered sidewall and longer at the bottom of the tapered sidewall to thereby reduce the residence time of the powder being milled at the top of the tapered sidewall and to increase the residence time of the powder being milled at the bottom of the tapered sidewall.
