| 20080265075 | Wear part for a VSI-crusher, and a method of reducing the wear on the rotor of such a crusher - A wear part for protecting a vertical rotor wall of a rotor of a VSI-crusher includes a wear body having a wear surface adapted for contacting abrasive particles. The wear surface is provided with at least one ridge extending over at least a portion of the wear surface. At least a portion of the length of the ridge is, when the wear part has been mounted to the vertical rotor wall, inclined in relation to a horizontal plane. | 10-30-2008 |
| 20080290200 | Inner shell intended for a gyratory crusher, and method of attaching such a shell on a crushing head - An inner shell has a first part of a lug-notch arrangement, which first part is arranged to co-operate with a second part of the arrangement to prevent rotation of the inner shell relative to a crushing head. The inner shell has a contact surface in its upper portion and is arranged to be pressed towards the lower portion of the crushing head by a pressing force which is obtained by tightening at least two threaded bolts, which are arranged in the upper portion of the crushing head such that their longitudinal direction is substantially parallel to the symmetry axis of the crushing head. | 11-27-2008 |
| 20080296418 | Distributor plate for a VSI-crusher, and a method of replacing such a plate - A replaceable distributor plate is adapted for protecting a lower horizontal disc of a rotor of a vertical shaft impact crusher. The replaceable distributor plate includes at least two separate pieces. The separate pieces are separated from each other along separating lines, as seen from above, each of which separating lines extend substantially from the center of the distributor plate to the periphery thereof. | 12-04-2008 |
| 20100090045 | Vertical shaft impact crusher - A vertical shaft impact crusher includes a rotor that rotates about a substantially vertical axis for accelerating a flow of material to be crushed. The crusher further includes a housing, a feed tube, and a feeding chamber. The housing includes a circumferential impact wall section against which the accelerated flow of material may be crushed. The feed tube is for vertically feeding a flow of material into the rotor to be crushed. The feeding chamber includes a feeding chamber side wall and is for vertically feeding a flow of material into the feed tube. A first door is provided for opening and closing an aperture in the feeding chamber side wall. The feed tube is removable from the feeding chamber via the first aperture. | 04-15-2010 |
| 20100108790 | Material feeding device for VSI-crusher - A vertical shaft impact crusher for crushing material including a rotor for accelerating a first flow of material to be crushed, a first feed device for feeding the first flow of material to the rotor, a housing that includes a circumferential impact wall section against which the accelerated first flow of material may be crushed, and a second feed device for feeding a second flow of material to be crushed into the path of the accelerated first flow of material. The second feed device includes an inner hopper and an outer hopper. The inner hopper includes at least one outlet for allowing the second flow of material to enter a space formed between the inner and outer hoppers. A slide plate inclined substantially tangential in relation to the rotor is located adjacent the at least one outlet in the space between the inner and outer hoppers. | 05-06-2010 |
| 20110062265 | CAVITY RING FOR A VERTICAL SHAFT IMPACT CRUSHER - A vertical shaft impact crusher includes a rotor for accelerating a first flow of material to be crushed, a first feed element for feeding the first flow of material to the rotor, a housing including a circumferential impact wall section against which the accelerated first flow of material may be crushed, and a second feed element for feeding a second flow of material towards a distributing wall section of the housing and further into the path of the accelerated first flow of material. A cavity ring separates the impact wall section from the distributing wall section. The cavity ring includes at least two ring segments. Supports are provided for supporting the ring segments. A locking device is provided for pressing the ring segments towards at least one of the supports. | 03-17-2011 |
| 20110101142 | Distributor plate locking mechanism for vertical shaft impact crusher - A replaceable distributor plate, adapted for protecting a lower horizontal disc of a rotor of a vertical shaft impact crusher, includes a first portion of a bayonet joint, the first portion being adapted for cooperating with a second portion of the bayonet joint, the second portion being associated with the lower horizontal disc. | 05-05-2011 |
| 20110253822 | HORIZONTAL SHAFT IMPACT CRUSHER - A horizontal shaft impact crusher, including a crusher housing having an inlet for material to be crushed and an outlet for material that has been crushed. An impeller is mounted on a horizontal shaft in the crusher housing and is operative for rotating around a horizontal axis. Material to be crushed is accelerated by the impeller against a curtain. An adjustment device is provided for adjusting the position of the curtain relative to the impeller. The crusher housing includes at least two guide rails to which the adjustment device is slidably connected. A retaining device is arranged to hold, with a predetermined holding force, the adjustment device in a crusher operation position relative to the guide rails. The adjustment device is movable along the guide rails from the crusher operation position and away from the impeller in response to an excessive force being transferred from the curtain to the adjustment device and exceeding the predetermined holding force. | 10-20-2011 |
