20090114753 | Circular Slot Magnetized Liner - The invention relates to a ring-slot type magnetic liner comprising guard plates, permanent magnetic bodies, binders and medium protecting layers, wherein, more than one dead slots are equidistantly arranged on the structure of said guard plates along the circumferential direction, a permanent magnetic body installed in each of said dead slots, and along the circumferential direction of the guard plate, one coil is set as N pole and the other coil is set as S pole. Each of the protecting layers is formed on the surface of the guard plate and is of annular shape in the circumferential direction. The invention allows the grinding operation to be carried out in the slots of the ring-slot shaped protecting layer which is formed from cracked grinding balls. The grinding balls contact the materials at an angle of about 120°, and the grinding efficiency is kept constant. Therefore the attritioning efficiency and yield may be increased. | 05-07-2009 |

20120217334 | CONFIGURATIONS AND METHODS FOR LINERS IN GRINDING MILL WITH GEARLESS MOTOR DRIVE - A grinding mill liner has a plurality of liner elements with respective bolt passages that are placed such that the passages, when the liner is installed into a mill shell, are placed outside a footprint of a peripheral device on the mill shell. Most typically, the peripheral device is a gearless motor drive that is operationally coupled to the mill shell in a position other than the end of the mill shell. | 08-30-2012 |
20120248231 | CUTTER ASSEMBLY FOR GRINDING AND CRUSHING MACHINES - A cutter assembly is presented for mounting to one or more hammers of a rotor assembly of a grinding machine. The cutter assembly includes a base, a tip and a fastener securing the base and the tip to the hammer. The base includes a key having side walls extending upwardly from a surface of the base and spatially oriented as sides of a pyramid that is truncated before reaching their apex. The tip includes a keyway having side walls extending inwardly from a lower surface into a body of the tip and spatially oriented as sides of a pyramid. The keyway mates with the key of the base. In one embodiment, the tip is reversibly mountable to the base such that cutting edges may be selectively used within grinding operations. | 10-04-2012 |
20130299618 | CRUSHING BODY AND METHOD OF MAKING THE SAME - A crushing body includes a wear body, inserts positioned in channels of the wear body, a mounting body positioned adjacent to the inserts and fasteners inserted into the mounting body to connect the mounting body to the inserts, the wear body, or both the inserts and the wear body. Preferably, the inserts are positioned so that a portion of each of the inserts is within the wear body and a base portion is adjacent to or engages the mounting body. Crushing devices such as mills, and crushers may utilize embodiments of the crushing body. | 11-14-2013 |
20130327868 | Interlocking Tip For Demolition And Construction Equipment - A tip for demolition and construction equipment has a discrete base with at least one recess therein to accept a replaceable insert. The insert has a projection that fits within a mating socket within the base. A threaded bolt may extend through a common bore within the insert and base to secure the insert to the base. The tip may also include a second opposing insert which is held within a respective recess by a common bolt. Finally, each insert may have a key which interlocks within a keyway of the base recess to securely hold the insert within the base and to distribute forces created by a cutting operation over a greater area. | 12-12-2013 |
20140027552 | KNIFE WITH DISPOSABLE INSERTS - A knife with disposable inserts. Either (1) a front side of the knife body has a cutting edge, the front side of the insert is removably mounted to a rear side of the knife body, and either (A) a rear side of the insert has a cutting edge, or (B) the rear side of the insert has a blunt face that forms a rear side of the knife; or (2) a rear side of the knife body has a blunt face that forms the rear side of the knife, the rear side of the insert is removably mounted to the front side of the knife body, and the front side of the insert has a cutting edge. | 01-30-2014 |
20140231567 | WEAR PACK FOR A DEMOLITION TOOL - A wear pack is disclosed for shielding a front end of a jaw set of a demolition tool. The wear pack may have a position portion provided on a bracket member for the alignment thereof prior to mounting. The wear pack may have a force transfer portion provided on the bracket member for the transfer of demolition forces to the front end of the jaw. The positioning portion may be contiguous with the force transfer portion. | 08-21-2014 |
