A method of manufacturing pulp using corn stalks may include cutting the corn stalks into pieces having a length of 10 to 60 mm, separating and discharging the cut corn stalks into rind and pith using a separation unit while crushing the cut corn stalks, pretreating the corn stalks by filtering the rind and pith of the corn stalks and flakes of the rind, removing a portion of hemicellulose of the rind, and cooking the rind from which the portion of hemicellulose has been removed, using caustic soda and sodium carbonate.

The invention relates to the method and device for milling and separation into fractions of solids and granular materials in a controlled airflow. The device for milling and separation of solids and granular materials consists of a round milling chamber with a system of pneumatic separation comprising of a vertical cylindrical body that has an uploading slot for solids and granular materials and unloading channels for the milled products of light, medium and coarse fractions. A rotating disc and a conical divider are located inside the vertical cylindrical body. The rotating disc has removable hammers and removable blades of different sizes and configurations. The system of pneumatic separation consists of a milling chamber, an air slugcatcher, channels for the milled material, and a chamber of higher pressure. Such a construction of the device allows to obtain products of the highest quality, and to improve the separation by dividing the material into three fractions: light, medium and coarse.

A chip separator configured to disentangle clusters of chips in a collection tank is disclosed. The chip separator includes a horizontal plate having a first surface and a second surface opposite the first surface, a motor assembly coupled to the first surface of the horizontal plate; and a pulverizer operably coupled to the motor assembly and disposed away from the second surface of the horizontal plate by a distance. The pulverizer includes a base plate and a plurality of pulverizer attachments operably coupled to the base plate. The motor assembly is configured to rotate the pulverizer such that the plurality of pulverizer attachments of the pulverizer disentangles clusters of chips disposed in the collection tank.

An abrasion wear resistant plate mountable to a rotor of a vertical shaft impact crusher includes a metallic main body, and at least four non-metallic tiles arranged on an upper surface of the main body to form a portion of a contact face facing an internal space of the rotor. Each of the tiles have an abrasion wear resistance greater than that of the main body, each one of the tiles having at least three edges each matching with and positioned against an edge of a neighboring tile.

A pulverizer for reducing a size of input material particles having a housing, a rotatable shaft with rotor arms and at least one airflow deflector cooperating with the rotor arms to deflect airflow within the pulverizer so as to form at least two overlapping vortices within the interior chamber such that input material particles in suspension in both overlapping vortices collide with each other to be thereby pulverized. The pulverizer also having a housing liner including a plurality of housing liner portions attached to and extending along a outer structural wall of the housing. The pulverizer also having a housing sidewall having an outer structural wall with a plurality of wall sections. The pulverizer also having canted rotor arms and rotor arms with removable wear pads. An anti-caking device for a vessel such as a pulverizer is also provided.

An impact crusher for grinding and separating solid material has a base, a rotor on the base having an upright shaft defining an upright rotor axis about which the rotor is rotatable, and a drum fixed on the base, spacedly surrounding the rotor, and formed by a pair of generally semicylindrical drum shells fitted together at a plane including the rotor axis. An array of axially extending and angularly substantially equispaced replaceable ribs is provided on an inner surface of the drum. A plurality of impact hammers are angularly substantially equispaced around the rotor and orbitable past the ribs on rotation of the rotor.
