Abstract: A method and arrangement for support of contact elements of hammermills and the like are disclosed in which a hardenable liquid bonding material is flowed into a chamber defined by registering recesses in facing relatively slidable surfaces of contact and support elements, the material being allowed to harden to define a key preventing relative slidable movement of the elements. A tongue-and-groove type of connection is provided for allowing the relative slidable movement while positively limiting relative movement in any direction in a plane transverse to the direction of the relative slidable movement.

Abstract: A method and arrangement for support of contact elements for material treating applications are disclosed in which a hardenable liquid bonding material is flowed into a space provided between surface areas of support and contact elements, the material being allowed to harden to provide a solid element which acts in compression to resiliently oppose relative movement of the elements. The space preferably has a cross-sectional configuration such that a wedging action is developed in response to relative movement of the elements. The holding element may be effectively burned out for removal and replacement of the contact element.
