A green compact forming device includes: a reservoir of powder; a first forming roll and a second forming roll structured to be adjacent to each other at a predetermined interval, the powder fed to a gap between the two rolls, the powder compressed into a sheet shape by rotation of the two rolls to form a green compact, the second forming roll supporting and conveying the green compact on a circumferential surface; a first information acquisitor structured to acquire powder information regarding an amount of the powder stored in the reservoir; and a controller structured to control a circumferential speed of the second forming roll based on the powder information.

The disclosure relates to a roller crusher that includes a frame, first and second crusher rolls arranged axially in parallel with each other and a deflection distributor. The roller crusher further includes at least one load sensor configured to detect a material load in the deflection distributor and at least one positioning sensor configured to detect a parameter pertaining to a distance between a first point and a second point of the roller crusher. At least the first point is defined on the deflection distributor or on one of movable bearing housings of the roller crusher. The disclosure further relates to a method for monitoring the physical condition of the deflection distributor and to a refitting kit for a roller crusher.

A method for test pressing pellets in a rotary press includes depositing material to be pressed into one of the plurality of receptacles of a die plate. The upper and a lower press punch are moved such that the upper press punch is positioned in an impact area of an upper test pressing tool of a test pressing apparatus of the rotary press. The lower press punch is positioned in an impact area of a lower test pressing tool of the test pressing apparatus. The upper and the lower test pressing tools are advanced towards each other via a test pressing drive of the test pressing apparatus so that the upper press punch and the lower press punch are driven towards each other in the one of the plurality of receptacles by the upper and lower test pressing tools to press the material in the receptacle into a test pellet.

A dry electrode manufacturing apparatus includes a plurality of rollers that laminate fine powder onto a current collector by calendaring the fine powder into a free standing film. A plurality of trimming knives adjust a film width of the free standing film passing by at least one roller among the plurality of rollers. A vision portion photographs a surface of the current collector on which the free standing film is laminated. A controller controls positions of the trimming knives based on the film width of the free standing film laminated onto the surface of the current collector.

A method for realising ceramic slabs or tiles, comprising the following steps: laying a soft layer (SL) of granular or powder ceramic material on a support plane (P); pressing the soft layer (SL) in order to obtain a compacted layer (CL); firing the compacted layer (CL); prior to the pressing, applying an identification mark (M) onto the soft layer (SL), the identification mark (M) having an optical contrast with respect to the soft layer (SL), so as to enable an optical detection of the mark (M); subsequently to the pressing, acquiring an image of the mark (M); processing the image of the mark (M) detected so as to control one or more operating steps subsequent to the pressing.

Control method for controlling the operating conditions of a rotary press machine (1) for forming tablets (100), wherein the rotary press machine (1) comprises a rotating compression turret (2) which includes a die table (3) provided along a circumferential portion thereof with a plurality of dies (4), a plurality of lower punches (6) and a corresponding plurality of upper punches (5) associated in pairs with respective dies (4), said lower punches (6) and said upper punches (5) respectively having a substantially cylindrical body equipped with an abutment end on which a lower compression roller (12) and an upper compression roller (11) respectively abut, a feeding station (7), a control system (20) to control the operating pressure of said lower and upper compression rollers (12, 11), in which during a detection phase the feeding of powder (50) into the dies (4) is inhibited so as to have at least one empty die (4a), said lower (6) and/or upper (5) punches are moved towards said at least one empty die (4a) by means of respective lower and/or upper compressing means, and a resisting pressure value is measured, by means of detection means (14), as the value of pressure exerted by the respective lower and/or upper compression means on the corresponding lower and/or upper punches (6, 5) moved inside said at least one empty die (4a), and an evaluation phase in which a value of said resisting pressure is processed by said control system (20) to generate a signal relating to a punch operating state.
