A milling assembly for a ball mill has a housing for refining and separating a substrate and a collection vessel for retaining the refined substrate. The housing includes, in vertical order, a lid, at least one milling vessel for receiving milling balls, and a screen with a refining section and apertures. The collection vessel is releasably mounted to a bottom end of the housing. The housing has an orifice arranged therein. The orifice has a valve for selectively allowing gas to pass between an outside and an inside of the housing in an open position of the valve and to seal the housing against the outside in a closed position of the valve. The milling vessel includes a taper for receiving a sealing screw.

A clamping system for a planetary ball mill includes a base, a clamping lid, including a clamping mechanism configured to secure a grinding container between the base and the clamping mechanism, and a lid configured to pivot with respect to the base from a closed position to an open position, wherein in the open position the grinding container is removable from the clamping system. The system further includes a rotatable arm configured to pivot between a first and second position, wherein in the first position the rotatable arm prevents the clamping lid from rotation to the open position. The clamping system also includes a balancing system having a first counterweight, with a linkage system being coupled between the first counterweight and a carrier plate of the planetary ball mill, the linkage system allowing the first counterweight to move with respect to a rotational axis of the carrier plate.

A method and apparatus to reclaim metals from scrap material such as automobile shredder residue (ASR) that, after separating out light density components, separates out friable material such as rock and glass by crushing and screening operations to generate a high metal content product.

A method of adapting a centrifugal machine that is a dual asymmetric centrifugal mixer or a planetary mill, used for mixing materials, for grinding one or more materials; it includes positioning in a container of the machine, non-spherical grinding media, and securing a lid on the opening of the container, wherein the bases of the units of the non-spherical grinding media are prevented from toppling by having a shortest distance between the center of mass of the unit of non-spherical grinding media and a base be less than half of the width of the base; or securing the lid sufficiently near the top of the units of the non-spherical grinding media such that when a unit of the non-spherical grinding media tilts, the unit of the non-spherical grinding media contacts the lid, the lid acting as an obstacle preventing the unit of the non-spherical grinding media from toppling.

The subject of the invention is a drive for an ultra-high-energy pulsatory-rotary mill that can be applied in the laboratory-class equipment. The objective of the invention is the use of the drive for an ultra-high-energy pulsatory-rotary mill which allows to accomplish the three-dimensional milling process in three axes with simultaneous control of amount of the supplied mechanical energy in real time. The rotary-planetary drive comprises an alternating-current motor (1) constituting the rotary motion drive and powered through an inverter (2) connected with the rotary mechanical energy counter (3), and an alternating-current motor (4) driving actuator (5) constituting the pulsatory motion drive and powered by inverter (6) connected with the pulsatory mechanical energy counter (7). Signals from mechanical energy counters (7) and (3) are conveyed to the digital recorder (8).
