A chipping sub assembly for use in material processing horizontal grinders includes a mounting structure with specialized connection elements for coupling to rotor assemblies. The assembly features individually replaceable components including knife elements and wear portions of varying thicknesses that can be selectively changed without removing the entire assembly. The mounting structure utilizes specific torque requirements and threading specifications, including -11 UNC, -13 UNC, and 1-8 UNC connections requiring between 110-818 ft-lbs. of torque, to ensure secure component attachment during high-stress grinding operations. The innovative modular design allows for rapid maintenance and performance optimization through interchangeable knife components with different length and material characteristics, while maintaining consistent wood chip quality suitable for resale. The assembly is compatible with various horizontal grinder systems and provides improved operational efficiency through reduced maintenance downtime compared to traditional fixed-component grinding assemblies.

The invention relates to a replaceable key grinding pan segment for a grinding track of a grinding pan of a roller mill, the grinding track having an annular shape with an outer circumference and an inner circumference around a center point. The length of the inner edge of the key grinding pan segment closer to the center point is greater here than the length of the outer edge further from the center point. The invention also relates to a grinding pan segment system, a roller mill, and a method for replacing grinding pan segments.

A crusher comprises at least one protective liner which is releasably fitted within the crusher so as to protect a structural element of the crusher which is subject to wear due to its contact with material passing the crushing gap, at least a part of an outwardly directed surface of the protective liner constituting a wear surface. The at least one protective liner comprises an elastic material layer and wear resistant inserts retained by the elastic material layer, wherein outwardly directed surfaces of the wear resistant inserts form part of the wear surface of the protective liner.

A jaw crusher and method or using the same is provided. The jaw crusher includes a crusher housing having an inlet for material to be crushed and an outlet for material that has been crushed. A moveable jaw, which has a wear plate and a stationary jaw, is provided with a second wear plate. The moveable jaw and the stationary jaw form between them a crushing chamber. The moveable jaw is coupled to an eccentric jaw crusher shaft, which causes the moveable jaw to reciprocate in an eccentric motion to crush the material between the moveable jaw and the stationary jaw. A toggle system is provided and includes a drive cylinder provided with an internally mounted sensor to measure the position of the moveable jaw relative to the stationary jaw.

A shell liner for a stirred grinding mill is configured to be releasably fitted to the inside of a shell of the mill within a grinding chamber thereof. At least a part of a surface of the shell liner that is configured to be exposed within the grinding chamber constitutes a wear surface. The shell liner includes at least one polymer-ceramics panel having an elastic material layer and wear resistant inserts retained by the elastic material layer. Exposed surfaces of the wear resistant inserts form part of the wear surface of the shell liner.

A screw flight system including a helical screw flight, and at least one wear lining element is disclosed. The screw flight system further includes a guiding system including at least one guide pin configured to be arranged on one of the helical screw flight and the at least one wear lining element, and at least one guide hole arranged on the other of the helical screw flight and the at least one wear lining element, wherein the at least one guide hole being configured to receive the at least one guide pin. A vertical grinding mill including the screw flight system, a replacement kit of wear lining elements, and a method for mounting thereof are also disclosed.

A system for a vertical grinding mill. The system includes a longitudinally extending shaft supporting a helical screw flight and at least one adaptor plate configured to be fixedly mounted to the shaft. Each adaptor plate includes at least one first locking member. The system further includes at least one wear segment configured to be supported by the at least one first locking member. Further, a replacement kit, a kit of wear protection elements and a vertical grinding mill is provided.

The invention relates to a rotor for an agitating mill having a generally cylindrical rotor body, the outer wall of which defines an inner surface of a milling chamber, through which a feed material to be treated flows during operation of the agitating mill. A ceramic ring is arranged at the rotor end of the rotor body, the rotor end being arranged opposite the product inlet of the agitating mill. The invention also relates to an agitating mill comprising the rotor according to the invention, to the use of the rotor according to the invention in an agitating mill for producing dispersions, and to a method for producing the rotor.

A compact eccentric crusher having a crusher jaw that includes a series of wear plates mounted to a frame. The frame of the crusher jaw includes a support surface that provide a mounting location for the wear plates. The wear plates are identical members mounted in an end-to-end orientation and retained on the support surface of the crusher jaw frame. An end stop is located at a second end of the frame and engages the lower wear plate. A master wedge is mounted at the first end of the frame and engages the upper wear plate. An auxiliary wedge is positioned between the wear plates and is secured to the frame to support the wear plates during operation of the compact eccentric crusher. The wear plates can be released and removed from the frame upon wear by removing the master wedge and lifting the wear plates from the frame.

The disclosure relates to a concave (20) of a cone crusher and/or gyratory crusher for installation inside a crusher head (30), wherein the concave (20) has a central longitudinal axis (M) extending in the longitudinal direction of the concave, wherein the concave (20) has a feed (24.1) for material to be crushed on its top (O) and a crushed material discharge area (24.2) on its opposite bottom (U), and wherein the concave (20) has a base part (21) having an outer clamping surface (28). In order to reduce the amount of parts and installation work, provision is made according to the disclosure for the base part (21) to have a support section (25) having fastening lugs (26) projecting radially outwards, wherein the fastening lugs (26) are disposed spaced apart from one another in the circumferential direction of the support section (25) by means of spacer areas, wherein at least one clearance is provided in each of the spacer areas, which clearances permit a penetration in the direction of the central longitudinal axis (M) from the bottom (U) in the direction of the top (O), and wherein the radially outward extent of the clamping surface (28) is greater, at least sectionally, than the radially outward extent of the fastening lugs (26).
