The present disclosure relates to a method of removing a liner from a mill, the liner fastened to a mill shell by at least one liner bolt, the method including: (a) driving the at least one liner bolt through the mill shell until it becomes retained in the liner, whereby in a retained position, a head of the at least one liner bolt is exposed so as to project proud of the liner towards an interior of the mill; (b) engaging a tool onto the at least one liner bolt; and, (c) lifting the liner away from the mill shell using the tool to thereby enable the liner to be removed from the mill. A system for removing a liner from a mill and tool for use in removing a liner from a mill are also described.

A wear panel for mining and materials handling applications is provided. The wear panel includes a housing matrix (1) with a top surface (2), a bottom surface (3) opposite the top surface (2) and at least one cavity (4) with cavity walls (5). The cavity (4) extends through the top surface (2) and the bottom surface (3). The wear panel also includes at least one wear-resistant member (6) with a preformed shape. The at least one wear-resistant member (6) has a top surface (7) and a bottom surface (8) opposite the top surface (7). The wear-resistant members (6) are disposed in the cavity (4) and are locked into place by their preformed shape and the cavity walls (5).

A mill includes a housing with a first end portion, a second end portion, and a lateral area disposed therebetween. The housing includes a raw material inlet, an air inlet, a recirculated material inlet, and a material outlet. An impeller is supported by the housing and includes a shaft disposed along the longitudinal axis of the housing, with a plurality of curved blades. A method for milling includes receiving a material of a first size range, introducing the material to an apparatus via a first inlet and introducing air into the apparatus via a second inlet. The method also includes agitating the material via an impeller, where the agitation reduces at least some of the material to a second size range by the time the material reaches an outlet of the apparatus. The processed material is delivered to subsequent processing operations.

In a discharge portion liner attachment structure for a vertical shredder including a sweeper supported below a rotor in such a manner as to be coaxial with a rotation shaft, a discharge ring disposed on a circumference portion of the sweeper, and a discharge portion through which a shredding target object that has been swept out through an opening formed on a circumference wall of the discharge ring by a sweeping operation performed by the sweeper is discharged to outside, discharge portion liners are attached in such a manner as to protrude from a side of the discharge portion to a side of the discharge ring in such a manner as to cover edge portions of ones of the discharge ring liners on a side of the opening.

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.

A breaker liner attachment structure for a vertical shredder including a rotor, a cylindrical shell, and a breaker, includes: a void that has an opening on an upper side and formed in an area between breaker liners in the breaker; and bolt insertion holes formed to extend from inner walls of the void to side surfaces of the breaker. Bolts are inserted into the bolt insertion holes via attachment holes formed in the breaker liners. The bolts are fastened with nuts from a side of the inner walls of the void.

A stackable wear panel (1) for use within a modular stackable wear-resistant panel system (11) is configured to be removably affixed to a wall (10A) or surface of equipment (10) to be protected. The stackable wear panel (1) is also configured to be alternatively removably affixed to a top surface (2A) of another stackable wear panel (1) within a stacked wear panel arrangement (1, 1). The stackable wear panel (1) is formed by a matrix (2) having a top surface (2A), a bottom surface (2B) opposite said top surface (2) and a central bore (4) extending through the top (2A) and bottom (2B) surfaces. The central bore (4) is configured to receive either one of a fastener (5) or a spacing adapter (6) therein, and/or support a portion (5A, 5B) of the fastener (5) or a lower outer surface portion (6E) of the spacing adapter (6).

An anvil adjustment assembly of a vertical shaft impactor includes an anvil ring configured to be disposed within a housing of the vertical shaft impactor. The anvil ring includes a tab which is coupled to an elongate jack bolt having a first end and a second end. A jack bolt housing partially surrounds the bolt and is coupled to the housing. A first locking collar and a second locking collar are coupled to the jack bolt. The first locking nut is coupled to the jack bolt on one side of the tab, and the second locking nut is coupled to the jack bolt on the opposite side of the tab. The jack bolt moves along a longitudinal axis within the jack bolt housing between a first position and a second position, and the movement of the jack bolt along the longitudinal axis induces longitudinal movement of the anvil ring.

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.

A mulching apparatus including: a housing including a front opening and an inner wall; a rotor mounted in the front opening of the housing adjacent to the inner wall; and a liner mounting system for mounting a replaceable wear liner between the rotor and the inner wall, the liner mounting system including: an upper mounting provided at an upper edge of the inner wall, the upper mounting configured to releasably connect with the wear liner; and a lower mounting provided at a lower edge of the inner wall, the lower mounting configured to support the wear liner against the upper mounting and secure the wear liner to the inner wall.
