Abstract: A roller press comprises a roller [100] having: a roller edge [110] formed by the intersection of a roller end [126] and an outer surface [128], an edge wear component [150] provided at said roller edge [110], and a mounting insert [160] provided within a mounting insert pocket [129] located inland of said roller end [126] and spaced from said roller edge [110]. A fastener [140] extends between the edge wear component [150] and the mounting insert [160] to keep the edge wear component [150] attached to the roller [100]. The fastener [140] threadedly engages female threads [164] provided within the mounting insert [160]. Also disclosed, is an edge protection system and method of mounting an edge wear component [150] to a roller [100] in a roller press.

Abstract: A method of forming a wearable surface of a body sized and configured to comminute material includes positioning at least one first insert in a first portion of a first metal structure at a first depth, positioning at least one second insert in a second portion of the first metal structure at a second depth and positioning at least one third insert in a third portion of the first metal structure at a third depth. At least one of these depths is different than the other depths. A second metal structure may be positioned adjacent to the first metal structure and at least one explosive material may be detonated to attach the inserts to the first metal structure. Material may then be removed to shape and form a wearable surface of a crushing body, which may be, for example, a crushing member or a segment of a crushing member.

Abstract: The invention relates to a roller mill for grinding solid material such as cement raw materials and similar materials, said roller mill comprising a substantially horizontal grinding table and at least two rollers which are configured for interactive operation with said grinding table. The roller mill also comprises a feed chute for delivering solid material to be ground by gravity to said grinding table that is a conveyor that fluidizes the material as it is being delivered to the grinding table.

Abstract: Disclosed is a method of producing a wear resistant layer on a substantially planar metal surface which is directly impacted in a comminution process, such as the impact surface of a grinding roller. A plurality of spaced apart wear plates are applied to the metal surface. The wear plates are anchored to the metal surface by a metallic welding material that forms a weld bond with the metal surface and a mechanical bond with the wear plates.

Abstract: A roller mill for comminuting solid material having a mixture of hard and soft components which is capable of acting on the solid material at two or more distinct pressures to thereby comminute both hard and soft components of the solid material.
