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 plant processing system may include a plant stripping apparatus with a frame and a plurality of stripping fingers including at least two groups of the stripping fingers being movable relative to each other. Each group of fingers may extend from a respective working surface, and the working surfaces may be oriented in substantial opposition to each other with a gap being formed between the first and second working surfaces to provide a pathway for movement of plant materials between an input and an output of the stripping apparatus.

摘要： Systems and methods for monitoring the roll diameter and shock loads in a milling apparatus may include a frame, a pair of rolls including a movable first roll and a stationary second roll, roll supports configured to support the first roll on the frame in a movable manner and the second roll on the frame in a stationary manner, and a motor assembly configured to rotate at least one of the rolls. Embodiments of the systems may also include a wear sensing assembly configured to detect wear on at least one of the rolls of the pair of rolls. Embodiments of the systems may also include a shock sensing assembly configured to detect shock to at one of the rolls.

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 roll grinding apparatus may comprise a frame, first and second rolls rotatably mounted on the frame in proximity to each other to grind materials passing between the rolls, and first and second motors to rotate the first and second rolls respectively. A control apparatus controls operation of at least one of the motors. The control apparatus may be configured to control the speed of the second roll by providing power to the second motor or braking the second motor through regeneration of energy from the second motor.
