A distributor plate assembly for a vertical shaft impact (VSI) crusher is optimized for abrasion wear resistance. The distributor plate includes a plurality of plate segments, each segment being formed from a main body of ductile iron alloy having cemented carbide granules embedded within the iron alloy.

A system is disclosed. The system includes an impact processor comprising an inlet and an outlet, a secondary classifier comprising an inlet and an outlet, the secondary classifier being downstream of and coupled to the impact processor, a recirculation mixer valve downstream of and coupled to the outlet of the secondary classifier, and a recirculation line coupling the outlet of the first secondary classifier to the inlet of the impact processor.

An apparatus and method for processing a crop residue, which includes but is not limited to, destroying weed seeds present in the crop residue. The apparatus (10) comprises an elongate housing (12) having an inlet (20) for receiving crop residue N and an outlet (22) for discharging the crop residue. The apparatus (10) also has one or more rotors (24), (26) located in the elongate housing (12). Each rotor (24), (26) comprises a plurality of radially extending impact members (28a), (28b), (28c), (28d), (28e), (28f) which rotate with the one or more rotors (24), (26) and impact against the crop residue, so that lighter material of the crop residue is subjected to less impacts and denser material of the crop residue is subjected to relatively more impacts.

Disclosed are systems and methods for refractory recycling that result in refined individual refractory components from a network of aggregate refractory components based on a fragmentation process. In one embodiment, a network of refractory aggregates is crushed and deposited into a refiner machine. The refiner machine includes a blast chamber that houses a projecting mechanism. The deposited aggregate material is propelled from the projecting mechanism at a critical velocity. Upon impact with an inner lining of material within the blast chamber, contaminant particles can fracture apart from the deposited aggregate material, leaving a refined individual refractory component.

The various embodiments disclosed and pictured illustrate a multi-connector hammer for comminuting various materials. The illustrative embodiments pictured and described herein are primarily for use with a rotatable hammermill assembly. The multi-connector hammer includes a connection portion having a rod hole therein, a contact portion for delivery of energy to the material to be comminuted, and a multi-connector neck portion affixing the connection portion to the contact portion. In other embodiments, a shoulder is positioned around the periphery of the rod hole for added strength. In still other embodiments, a neck reinforcement is positioned along a portion of the neck for increased strength. A weld or plurality of welds may be affixed to various surfaces of the contact portion to aide in comminuting and/or longevity of the multi-connector hammer.

A method for separating composite materials and mixtures, in particular solid-material mixtures and slags, and to a device for carrying out said method. The method for separating composite materials and mixtures comprises the step of transporting the composite material or the mixture through a separating device. The composite material to be separated or the mixture to be separated is excited by mechanical impulses as it passes through the separating device and is thereby separated. The device (1) for carrying out the method comprises a drive unit (21) for driving a rotor element (32), which is connected to a bearing/shaft unit (22) and which is part of a rotor unit (31). The rotor element itself has at least one rotor tool (33) and each rotor tool has at least one rotor tool component (34) and is surrounded by a stator element (42), which is part of a stator unit (41). The stator element itself has at least one stator tool (43) and each stator tool has at least one stator tool component (44). The rotor element and the stator element are substantially cylindrical.

Vertical shaft crushers and control systems therefor are disclosed. In some embodiments a rotor of the crusher is reversible and/or autogenous. In some embodiments a crushing chamber of the crusher includes at least one anvil and at least one rock shelf chamber.

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.
