The invention concerns a tablet press (10) which is typically portable and comprises a base (12) and a press member (24) held relative to the base by a spacer (20). The base (12) comprises a die (38B) for receiving a powder in use, wherein the spacer (20) depends from the base and is moveable relative thereto under the control of an actuator (28) such that the press member (24) is reversibly actuable between an at-rest condition in which the press member is spaced from the die and an actuated condition in which the press member is located in the die so as to apply a load to a powder therein so as to compact the powder into a tablet. The actuator is operated under the control of an electronic controller, typically in response to desired tablet parameters input by a user. A table-top tablet press of this kind is particularly beneficial for individual or small-batch tablet production, for example for research purposes.

In a production method for permanent magnet, a magnetic powder is loaded into a cavity formed in a groove shape whose longitudinal direction horizontally extends. A loading step of loading the magnetic powder includes a first loading step of loading, of the magnetic powder, a first magnetic powder containing no heavy rare earth element or containing a heavy rare earth element, and a second loading step of loading, of the magnetic powder, a second magnetic powder having a higher content rate of heavy rare earth element than that of the first magnetic powder, at a predetermined position in the cavity.

A tablet press for producing tablets including: a press chamber, a receiving chamber, a first material container having the first active substance with a first dosing device, a controller, and an input device. The press chamber has an extendable upper punch, an extendable lower punch, and a die. The input device inputs a target indicating a number of produced tablets and a target mass indicating a quantity of the first active substance and transmits the target number and the target mass to the controller. The controller actuates the first dosing device, the upper punch, and the lower punch such that a quantity of the first active substance that corresponds to the target mass is filled into a central opening of the die and pressed by the punches to form a tablet, and to repeat until the target number of tablets are produced.

A method of manufacturing compacts and an arrangement for manufacturing compacts, in which the disadvantages of the state of the art are overcome and an efficient method and at the same time a simple construction and a simple implementation are achieved. This involves a method for manufacturing compacts, wherein after feeding the feedstock, pre-pressing into a pre-agglomerate using at least one pre-pressing punch or at least one stuffing screw and subsequently main pressing of the pre-agglomerate into a compact in at least one pressing die using at least one main pressing punch and subsequently ejection of the compact from the at least one pressing die are performed, pre-pressing, main pressing and ejection being performed in a mutually parallel working direction. This also involves an arrangement for manufacturing compacts, wherein at least one pressing die is provided in die tool receptacle with a feed for feedstock.

A dust compaction system includes a compaction device including a hopper with an input port into which a dust is input and a discharge port from which the dust is discharged, and a compaction unit configured to form pellets by compressing the dust supplied from the discharge port of the hopper, and the dust compaction system further includes a suction device configured to suck in the hopper of the compaction device.
