A process for fibrillating a fibrous pulp, and products made using the same. The process comprises providing a fibrous pulp of liquid and staple fibers having a first liquid to fibers ratio of less than or equal to 6:1, applying stress to the pulp to fibrillate the staple fibers; and, during said applying stress, drying the pulp to a second liquid to staple fibers ratio of less than or equal to 0.43:1.

A machine, particularly for producing cellulose fiber from waste paper with characteristics and yield comparable to virgin fiber, includes at least one conveyor body which is adapted to receive the waste material from which to obtain cellulose fiber; and at least one drum which contains inside it grinders adapted to grind the waste material for the production of the cellulose fiber, and which communicates with the conveyor body.

The grinders include a grinding hammer which is arranged on the bottom of the drum and can rotate by way of a motor about a rotation axis.

A pulverizer may have such features as an ability to detect wrapping as well as possibly deter wrapping. A processor may also adjust the speed of rotation of the arms within the pulverizer and/or the speed of feed of input for various considerations. In fact the rotation direction may be reversed for at least brief periods of time in an effort to remove wrapped material. Vibration may also be sensed and efforts to prevent damage may be instigated by a processor.

An impact processing device has a central impact mechanism arranged to rotate about a rotation axis and a first processing stage that includes the impact mechanism and a first structure extending circumferentially about the impact mechanism. The first structure has a first processing sector, and a first screening sector, where the processing sector extends for a first circumferential portion of the first structure and has an impervious textured surface and the first screening sector has a plurality of holes and extends for a second circumferential portion of the first structure. The impact mechanism is operable to impact material against the first processing sector and generate a flow of the impacted material to first screening sector through which at least a portion of the impacted material can pass.

The present disclosure relates to the treatment of streams derived from construction and/or demolition (C&D) debris, such as C&D fines streams, asphalt shingles, drywall, or wood. The process can include a kinetic pulverization stage through a kinetic pulverizer where the frangible materials are size-reduced and the ductile materials are liberated and remain as an oversized fraction. The feedstock can include infrangible materials that also remains as an oversized fraction. The pulverized material is then subjected to a separation stage, which may include mechanical and/or magnetic screening, to separate the oversized material comprising the ductile material, and optionally larger particles of the infrangible material, from the size-reduced material comprising the frangible material, and optionally small particles of infrangible material.

The present invention relates to a high-speed dewatering and pulverizing turbine (1) for obtaining solid pulverized particles and dissociating the water present, which is formed by: a) a stator (6) having circular geometry with a duct at one end (7) for the outlet of the solid pulverized particles and a duct in the bottom part (10) for the inlet of solid particles to be pulverized; b) a wheel or rotor with vanes or blades, located inside the stator; and c) a central securing assembly for adjusting and securing all the elements that form the wheel or rotor. Also described is a method for obtaining solid pulverized and dewatered particles, wherein the water present is separated.

The present invention relates to a device for treatment of a material mixture consisting of substitute fuel and impurities, having a vertically aligned central feeder (1), a separating unit (2) arranged underneath the central feeder (1), a rotor mill (3), wherein the rotor mill (3) is arranged above the separating unit (2) and surrounds the central feeder (1), a flow device (4) for generating an upwardly directed gas flow, wherein the rotor mill (3) has a multistage design, and a respective separating device (6) is arranged between the stages (5.1, 5.2) of the rotor mill (3), wherein material mixture not held back by the separating device (6) is further comminuted in the following stage (5.2).
