Patent number: 8517473Abstract: A road grading pick includes a cutting head, a shank, a shoulder at a transition between the cutting head and the shank, and a polygonal-shaped washer or an oval-shaped washer. The shank is positioned in an opening of the washer to position the washer along a longitudinal length of the shank between a rearward end of the shank and the rearward facing surface of the shoulder. In a preinstalled position, the washer compresses a friction retainer on the shank of the road grading pick to facilitate seating of the road grading pick in a blade of a road grading apparatus. In an installed position on an adapter board for a moldboard of road grading equipment, the friction retainer is no longer in the opening of the washer and the washer prevents washer rotation and shields an underlying mounting surface while allowing rotation of the road grading pick.Type: GrantFiled: May 4, 2009Date of Patent: August 27, 2013Assignee: Sandvik Intellectual Property ABInventors: Kenneth Monyak, Joseph Fader, Lars-Åke Carlsson

Patent number: 8496413Abstract: End mill, primarily for coarse machining, has even number of main flutes spiraling around the periphery of the mill, the flutes having a relatively smaller and a relatively larger helix angle relative to the axis of the mill and wherein uneven-numbered main flutes are defined in that they include the smaller helix angle with the axis. Directly at the end face, distances between peripheral angles of successive main flutes in the direction of rotation are smaller between uneven-numbered main flutes and subsequent even-numbered main flutes than the distances between peripheral angles between even-numbered main flutes and subsequent uneven-numbered main flutes. The end mill is better able to prevent vibrations of the tool due to intermittent engagement with a work piece by having all distances between peripheral angles at the end face of the mill different from one another.Type: GrantFiled: March 30, 2009Date of Patent: July 30, 2013Assignee: Sandvik Intellectual Property ABInventor: Maurizio Tardivo

Patent number: 8496195Abstract: The present disclosure relates to a method for operating a gyratory cone crusher as well as a hydraulic circuit suitable for carrying out the method. A crusher comprises an inner crusher shell and an outer crusher shell, which define a crusher gap, and the crusher gap size is maintained by means of a hydraulic cylinder, and, in case the hydraulic liquid pressure exceeds a pressure threshold, hydraulic liquid is evacuated from the cylinder to increase the crusher gap size. The method involves carrying out detection of a tramp iron processing condition, implying that matter which the crusher cannot process has enter the gap. If such a condition is detected, the pressure threshold is lowered during a period of time. This means that the crusher gap is opened quicker, such that the matter that cannot be crushed is removed from the crusher, which is thereby protected from potentially detrimental impacts.Type: GrantFiled: December 20, 2011Date of Patent: July 30, 2013Assignee: Sandvik Intellectual Property ABInventors: Patrik Sjoberg, Mauricio Torres

Patent number: 8490262Abstract: A hand tool which features a self-aligning recessed seating feature for easy installation of retaining clips onto the groove of the shank of mining and trenching picks. The location and orientation toward the first end of the body of the tool of the recessed seating feature allows for easy installation from either the left or right side of the holder. The tool includes two prongs located at the same end of the tool as the recessed seating feature. The end surfaces of the two prongs correspond in shape and/or orientation to the contact surfaces of a retaining clip to improve removal of retaining clips from the groove of the shank of mining and trenching picks.Type: GrantFiled: January 4, 2010Date of Patent: July 23, 2013Assignee: Sandvik Intellectual Property ABInventors: Kenneth Monyak, Joseph Fader
