Patent number: 10343171Abstract: A wear part for a mineral material processing apparatus includes an outer wear surface which includes an initial phase wear surface to be put in crushing contact with an opposite wear surface, and an end phase wear surface to be taken vertically into use in the crushing process from under the initial wear surface when the wear is progressing. The wear part includes an end phase wear surface with a protrusion to be put in use when the wear of the outer wear surface is progressing. As a result of the wear part including the protrusion working life of the wear part can be prolonged. A mineral material processing apparatus and a mineral material processing plant.Type: GrantFiled: November 13, 2015Date of Patent: July 9, 2019Assignee: Metso Minerals, Inc.Inventors: Kari Peltomaki, Tero Onnela, Jouni Mahonen, Mikko Malkamaki

Patent number: 9724696Abstract: A wear part for a jaw crusher comprises at a first side a wear surface to be directed to a crushing chamber of the crusher; and at an opposite second side a first counter surface which is fixable against a fixed or movable jaw of the crusher in a detach-able manner. The wear part comprises second counter surfaces inclined in opposite directions, for holding the wear part in place vertically and in a centering way in side direction relative to the jaw. A jaw crusher, a mineral material processing plant and a method for fixing a wear part to a jaw of a jaw crusher in a detachable manner. A wedge tightening coming from three directions is locking the wear part in a centering way in place relative to any possible transfer direction.Type: GrantFiled: March 19, 2012Date of Patent: August 8, 2017Assignee: Metso Minerals, Inc.Inventor: Kari Peltomaki

Publication number: 20040142200Abstract: A method of manufacturing erosion-resistant wearing parts and a wearing part are disclosed, whereby the wearing part manufactured according to the invention comprises at least one hard powder composition (A) and at least one ductile powder composition (B) that together are densified in a single pressing step into an entirely dense product. According to the method, the temperature coefficient of the hard powder composition (A) is controlled by keeping the temperature coefficient of the hard powder composition smaller than that of the encapsulating powder composition (B), whereby the hard powder composition (A), with the exception of the outer erosion-subjected surface of the wearing part, remains entirely encapsulated by powder composition (B) so effectively that the imposed eroding forces cannot essentially extrude the hard powder composition (A) out from the wearing part through its erosion-subjected outer surface.Type: ApplicationFiled: September 2, 2003Publication date: July 22, 2004Applicant: Metso Powdermet OyInventors: Jari Liimatainen, Mikko Malkamaki, Kari Peltomaki, Jukka Lehtonen
