Patent number: 9827595Abstract: A screening media of a vibrating screen screens fractions of stone or gravel. The screening media is formed of ribs extending from one end of the screening media to the opposite end thereof. Pins projecting perpendicularly from the ribs are placed on opposite sides of the ribs. Each pin ends at a distance from an adjacent rib. The dimension and placement of the pins are such that a continuous aperture is formed between two adjacent ribs. Each aperture is formed of a number of rectangular screening areas of identical size. Each screening area is placed perpendicular to each adjacent screening area and end areas of adjacent screening areas coincide.Type: GrantFiled: March 10, 2014Date of Patent: November 28, 2017Assignee: SANDVIK INTELLECTUAL PROPERTY ABInventor: Mats Malmberg

Publication number: 20160250643Abstract: A gyratory crusher sealing ring assembly includes an annular body with a first part that mates with a sealing surface provided at an underside region of the crusher head and a second part for mounting the body at a support part axially below the head. The sealing ring is configured so as not to flex or bend in response to the sliding contact between the ring and the head surface. The ring has a Young's modulus (E-modulus) in the range 1700 to 4300 MPa and is substantially rigid. The ring is biased against the sealing surface of the head via a bias component or region.Type: ApplicationFiled: September 19, 2014Publication date: September 1, 2016Inventors: Adrien HENSSIEN, Mats MALMBERG

Patent number: 8622219Abstract: A screening media for use in vibrating screen devices that fractionize crushed stones or gravel. The screening media is made by extruding a fiber-reinforced rubber or polymeric material to form a strip in a length longer than that needed to make individual screening mats for use in the vibrating screen devices. Screening apertures are then punched in the strip, and the apertured strip is cut into individual mats. The extruded strip includes side portions configured to connect to support structures of the vibrating device. Prior to the cutting step, the apertured strip can be maintained in the form of a coil or a long-length element.Type: GrantFiled: February 24, 2011Date of Patent: January 7, 2014Assignee: Sandvik Intellectual Property ABInventor: Mats Malmberg
