摘要： A grinding apparatus may include a frame and a pair of rolls each having a circumferential surface and being rotatably mounted on the frame, and a plurality of teeth located on the circumferential surface. In embodiments, at least one roll comprises a roll body structure rotatably mounted on the frame and a roll cover structure forming the circumferential surface, and the roll cover structure may be at least partially removable from the roll body structure to permit replacement of at least a portion of the circumferential surface without requiring removal of the roll body structure from the frame. In embodiments, the teeth on one roll may include an upper cap portion formed of a relatively harder material and a lower base portion formed of a relatively softer material. In embodiments, the teeth on one roll have a coating of a relatively harder material than a relatively softer base material forming the tooth.

摘要： A bearing assembly for rotatably supporting a rotating body on a frame may include a bearing support block having a plurality of block mounting bores for each being axially aligned with a bearing mounting hole formed in the frame, and at least one mounting bolt removably insertable into one of the block mounting bores and into a bearing mounting hole, with the mounting bolt having exterior threads for threading into interior threads on one of the bearing mounting holes on the frame. One block mounting bore may have interior threads formed thereon, and the interior threads of the block mounting bore may incompatible with the exterior threads of the mounting bolt such that the mounting bolt is not threadable into the block mounting bore. An apparatus and system is also disclosed.

摘要： An apparatus for sensing characteristics of particles in a flow of particles may include a guidance structure configured to guide particles of a stream of particles taken from the flow of particles. The guidance structure defines an inclined surface across which particles of the stream of particles move. The apparatus may further include an image capturing device configured to capture at least one image of particles located on the inclined surface.

摘要： A method and apparatus for grinding a particulate material is disclosed. The method may include providing a system including a roller mill apparatus and a hammermill apparatus, operating the roller mill apparatus and the hammermill apparatus, adjusting a feed rate of particulate material to the roller mill apparatus until power consumption by operation of the roller mill apparatus achieves a target power consumption for the roller mill apparatus, and adjusting a gap between mill rolls of the roller mill apparatus until power consumption by operation of the hammermill apparatus achieves a target power consumption for the hammermill apparatus. The system may include roller and hammermill apparatus with sensing and controlling apparatus configured to operate the roller and hammermill apparatus according to the methods disclosed.

摘要： A system may comprise a frame, a pair of rolls with each of the rolls comprising a roll body having opposite ends and a circumferential surface, a plurality of teeth being formed on the circumferential surface, and at least a portion of the circumferential surface being electrically conductive. The roll may also have a roll shaft having end portions extending from the roll body, with each of the end portions extending from one of the ends of the roll body. The system may also comprise roll supports configured to support the rolls on the frame in a manner such that at least one of the rolls is movable to adjust a separation gap between the rolls, a detection apparatus configured to detect contact between the rolls, and a signaling apparatus configured to produce a signal indicating a change in electrical potential is detected by the detection apparatus.

摘要： A system for grinding comprises a first grinding apparatus and a sifting apparatus to receive particles from the first grinding apparatus and to remove and divert particles having a size less than a threshold size from a particle path to an output stream such that the particles are not subjected to further grinding. The sifting apparatus comprises a first particle removal stage configured to remove grain particles of a first size and larger, and a second particle removal stage configured to remove grain particles of a second size and larger from the grain path. A second grinding apparatus may be configured to grind grain exiting the sifting apparatus and to output to the sifting apparatus. A method is also disclosed.
