Abstract: A coffee machine, including a grinder configured to grind coffee beans, and a coffee machine made to remove waste, such as chaff, from a separation area, where the waste such as chaff is separated from ground beans. The coffee machine includes a first grinder configured to grind the coffee beans by grinding, a separation area where the waste is separated from the ground beans ground by the first grinder. And, the waste from the separation area is cleaned by wind pressure while the first grinder is in a stop state.

Abstract: A process for separating carpet fibers from carpet backing uses a grinder of the type having a rotor with a plurality of vertically spaced cutter discs and a fan disc below the cutter discs. Sections of carpet are fed into the grinder which grinds the carpet, separating the fibers from the backing and breaking the backing into relatively small particles. The grinder is connected with a series of ginning equipment for removing the ground backing from the fibers.

Abstract: A method and apparatus for treating materials or material mixtures in a treatment apparatus operating on the principle of the double-action impact mill, which includes a discharge conveyor (34), such as a discharge screw. A material layer (40) is maintained between the discharge opening and the discharge conveyor, using the material exiting the outermost ring (16?) of the treatment apparatus through the discharge opening (30), which layer prevents free discharge of the material to be treated from the treatment apparatus.

Abstract: An apparatus for converting unconsolidated medical waste into a non-hazardous medical waste residue, which apparatus has an improved cutter assembly provided by a rotating cutter assembly that has revolving teeth disposed at an oblique angle relative to the path of travel of the revolving teeth and to the stationary cutter assembly to force the waste material between the revolving and fixed teeth. An auger moves the waste material through the housing longitudinally to keep pressure on the opposing fixed and revolving teeth while grinding the material into a reduced particle size to facilitate its disposal or storage.

Abstract: A pulverizing system which reduces the size of solid particulate material such as drill cuttings from a wellbore is disclosed. The pulverizing system includes a pair of interconnected cylindrical chambers with each chamber having a rotatable shaft with a plurality of disc sets mounted thereon. The shafts are aligned in parallel relation and operate in a counter rotating manner. Each disc set includes at least one pivotally mounted thrust guide in the form of a bar shaped member. In one embodiment, the thrust guides of the two shafts are arranged in an alternating, interdigitating pattern. The chambers are divided by transverse baffle walls into compartments, with each baffle wall having an opening therein for passage of the particulate material.

Abstract: An apparatus and method for continuously chopping, pulverizing and mixing edible material such as animal or fish meat which involves continuously chopping square-shaped frozen blocks of the material and adding thereto sodium carbonate or sodium bicarbonate, and sodium chloride or sodium caseinate, mixing and pulverizing the resultant mixture and adding an emulsifying agent thereto to prepare an emulsion. The method is further applicable to chopping, pulverizing and mixing beans by continuously chopping square-shaped frozen blocks of coarsely ground beans and pulverizing the chopped material.

Abstract: A multi-stage process, and apparatus for carrying out the process, are provided for refining lignocellulose containing material at high consistency. The lignocellulose material is pretreated to form a mixture of the lignocellulose material and pressurized steam conveyed via the pressure of the pressurized steam to a first refiner, wherein the lignocellulose material is conveyed mechanically into a first refining zone within the first refiner while causing the pressurized steam in the mixture to pass in reverse direction to the lignocellulose to a steam venting outlet to vent the steam from the first refiner. The lignocellulose material fed into the first refining zone is subjected to refining action thereby producing a mixture of partially refined lignocellulose material and pressurized steam developed during the refining action.

Abstract: Method and an apparatus for controlling the production of thermomechanical pulp meter chips by metering elements (9, 10) into a feed chest (2), and by feed elements (3, 7) connected to the feed chest feeds chips for refinement between thermomechanical pulp refining discs (5). Water is added to the chips prior to feeding the chips between the discs (5). Moisture content of the thermomechanical pulp is measured after the thermomechanical pulp refiner at least in a semicontinuous fashion by at least one measurement device (21, 22, 23, 24) operating on-line, and on the basis of measured moisture content, the quantity of chips and water to be metered is controlled so as to regulate the moisture content to a desired level of having a constant value by, e.g., increasing the volume of metered chips and simultaneously decreasing the quantity of fed water for an increasing trend of moisture content, and correspondingly, applying an opposite strategy to counter a decreasing trend of moisture content.

Abstract: A comminuting device for commercial or industrial waste in the form of paper, plastics and the like comprising a downward feeding hopper, having a rotary cutting mechanism associated with a bottom discharge opening and a crushing and conveying tool above and rotating with the rotor has the discharge opening aligned substantially vertically to pass centrally or chordwise through the lower region of the hopper and the rotor is equipped at its circumferential face with knives disposed one above the other to travel through a substantially cylindrical cutting area traversing the discharge opening.

Abstract: A machine for comminuting bulk objects such as wood or the like includes a receptor forming in its lower part, a funnel, a guide means at the inner side of the funnel, a comminuting device below the funnel, and a transport and pre-breaking means within the funnel and rotating therein with the comminuting device. The comminuting device includes a rotor rotatable about a vertical axis and having a plurality of cutting edges and at least one stator mounted on the funnel and also having cutting edges. The cutting edges of the rotor traverse an annular working plane which is perpendicular to the rotational axis of the rotor with the annular working plane overlapping with the cutting edges of the stator.

Abstract: Method and apparatus for producing pulp from moisture-containing lignocellulosic material, such as wood chips, which is ground in a grinding space defined between a pair of grinding discs which rotate relative to one another in an environment of pressurized steam generated during the grinding process, in a closed housing. The ground fiber or pulp discharged from the grinding housing is propelled by the accompanying steam into a cyclone, where the ground pulp is separated from the steam for further treatment, while the steam is recycled for further use in the pulping process. The pressure in the cyclone is so controlled that a pressure is maintained therein which is substantially equal to a pressure drop which is sufficient merely to maintain the propellant force of the steam to convey the ground pulp from the grinding housing to the cyclone while discharging the separated steam and recycling it for further use in the pulping process.

Abstract: A machine for the continuous comminution and mixing of materials, especially animal and vegetable media, has a mixing chamber in which two conveying passages are arranged. Each passage has a conveyor and mixer element working oppositely to one another, with each conveying passage there is associated a comminuting device which at the same time acts as a conveying means to deliver materials in the same direction as the associated conveying and mixing elements into the relevant conveying passage or respectively draw therefrom. Reversing spaces or passages serve together with these passages for the circulation of the mixed material.
