A pill management device includes a portable reservoir having a pill-receiving inlet and an access door spaced from the pill-receiving inlet, a pill-crushing mechanism disposed within the reservoir and configured to transform a solid pill, introduced via the pill-receiving inlet, to pill powder, and a locking mechanism in communication with the access door and the pill-receiving inlet for preventing unauthorized access to the pill powder housed within the reservoir. Advantageously, the locking mechanism locks the access door and the pill-receiving inlet.

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.

A roller mill module with a fixed grinding roller with a first grind surface rotatably supported within a grind area between a first drive end and a second drive end of a support structure; an adjustable grinding roller with a second grind surface rotatably supported within the grind area; the adjustable grinding roller movable with respect to the fixed grinding roller to adjust a grind gap between the first grind surface and the second grind surface; a drive shaft of the fixed grinding roller and a drive shaft of the adjustable grinding roller extending from the first and the second drive ends of the support structure; and a sample port provided in a front side of the support structure; a sample passage coupled to the sample port extending to a position below the grind area and opposite a sampler stop surface.

A roller crushing machine for progressively crushing solid particulate material into finer size particulates is disclosed. It has a plurality of spaced-apart crushing stages arranged so that, a flow path of particulates travels consecutively from one crushing stage to the next, in between the outer peripheral surfaces of the rollers, which are adjustably displaceable from each other by a lateral distance not greater than a desired maximum particulate size from that crushing stage. When a flow of solid particulate material passes between cach of the pairs of rollers, the predetermined lateral distance encountered by the flow path can be controlled to be of a dimension which is sufficiently operably narrow to only apply a sufficient compression breakage force to just the topsize of the particulates at that size range of preselected solid particulate material, and a mono-layer flow of particles passing therethrough, to minimize energy consumption in that stage.
