| 241032000 | With overload release means | 6 |
| 20130186989 | PADDLE ASSEMBLY - A radially projecting member (e.g., a paddle assembly) including a pin having a head; a paddle pivotally engaged to the head; and a shear member engaged to the head and to the paddle, the shear member being constructed and arranged to fracture to permit pivotal rotation of the paddle relative to the head. | 07-25-2013 |
| 20130334348 | APPARATUS AND METHOD FOR A CRUSHER WITH AN INVERTED CYLINDER - A crusher adapted to crush feed materials comprising a main frame, a secondary frame disposed adjacent to the main frame, a crushing chamber adapted to receive feed materials, and a tramp iron relief system comprising a cylinder. The tramp iron relief system is adapted to allow a portion of the secondary frame to move away from the main frame. The cylinder is disposed substantially adjacent to the secondary frame. A method for installing a cylinder on a crusher and a method for removing a cylinder from a crusher wherein a lifting device remains attached to the cylinder continuously during each operation. | 12-19-2013 |
| 20140166792 | COMMINUTION DEVICE - The invention refers to a comminution device, such as for example a shredder (II) or the like for in particular large-size materials, with a main drive (I) generating a rotational movement for a shredder shaft ( | 06-19-2014 |
| 20150360228 | HYDRAULIC CYLINDER SYSTEM FOR ROCK CRUSHERS - A rock crusher is provided that has a crusher cavity defined between a first part and a second part. The crusher includes a plurality of hydraulic cylinders mounted between the first and second parts, each of the hydraulic cylinders formed of cylinder barrels and including a base and a plurality of oil passages longitudinally extending and evenly spaced around and within the cylinder barrels, each of the oil passages including a first port accessing the interior of the hydraulic cylinder at a point remote from the cylinder base, and a second port disposed adjacent the cylinder base. A hydraulic pump may also be included, providing oil pressure to the hydraulic cylinders. A relief system is included for reducing oil pressure within the hydraulic cylinders in the event uncrushables enter the crusher cavity, the relief system including a relief valve disposed adjacent the cylinder base and in hydraulic communication with the second ports, the relief valve designed to open when hydraulic pressure in the hydraulic cylinder reaches a predetermined level, thereby reducing pressure in the hydraulic cylinder as oil pressure is dumped from the hydraulic cylinder via the oil passages. | 12-17-2015 |
| 20160074867 | CRUSHER - A crusher comprising a box-like crusher frame with two end walls and two side walls connecting the end walls; at least one crusher rotor that is supported for a rotating movement inside the crusher frame against its end walls; the circumference of the crusher rotor having a plurality of crusher teeth and the crusher having counter-blade structures arranged to cooperate with the crusher teeth of the crusher rotor, and the material fed into the crusher for crushing being intended to be fed essentially above the centre line of the rotor(s) and to be crushed between the crusher teeth of the crusher rotor and the counter-blade structures; wherein two hatches are arranged on at least one side wall side of the crusher, the first hatch being above the centre line of the crusher rotor and pivoted at its top part to the crusher to be turnable toward the centre line of the crusher, and the second hatch being mainly below the centre line of the crusher rotor and movable away from the front of the crusher rotor. | 03-17-2016 |
| 20160114330 | A GRINDING APPARATUS - A grinding apparatus comprises a receptacle, a grinding element and a drive means. The receptacle has a receptacle inner wall defining a receptacle cavity. The receptacle inner wall is in the general form of a surface of a revolution extending about a central vertically extending receptacle axis. The receptacle is rotatable about the receptacle axis. The grinding element has a grinding element outer wall in the general form of a surface of revolution extending about a central vertically extending grinding element axis. | 04-28-2016 |
