An ink mixture is manufactured by mixing carbon, graphite, and solvents in a mixing system which may include a Cowles disperser. The conductive portions (e.g. carbon, graphite) are evenly and universally dispersed, because an even dispersal means the conductivity of the resulting conductive strip (electrode) will be even, consistent, and reliable. The various embodiments of the ink mixture comprise a blend of different conductive pigments, including but not limited to carbon black and graphite. These embodiments must be grinded until below 6.5 Microns in particle size.

The present invention relates to a method for producing tetrahydridoborate salts with high efficiency at low cost. The method for the production of metal borohydride salts according to the present invention comprises the steps of providing an anhydrous metal borate salt and milling the anhydrous metal borate salt in the presence of a metal material based on magnesium or magnesium alloys in a hydrogen atmosphere at a temperature and for a time sufficient to produce the metal borohydride salt. In another embodiment of the invention, the method for the production of metal borohydride salts according to the present invention comprises the steps of providing an hydrated metal borate salt and milling the hydrated metal borate salt in the presence of a metal material based on magnesium or magnesium alloys in an inert gas atmosphere at a temperature and for a time sufficient to produce the metal borohydride salts. In a still further embodiment of the invention, the metal material based on magnesium or magnesium alloys is a secondary magnesium material, preferably a Class 2, Class 3, or Class 6 secondary magnesium material.

The media-circulation type pulverizer comprising: an agitating member disposed in a lower region of a pulverization chamber; an annular partition wall disposed to extend upwardly in the pulverization chamber; and a media guide member provided on a lower surface of the end plate of the agitating member, wherein the annular partition wall has a height set to be to of a height of the pulverization chamber, and the media guide member has a lower end which enters a space of the inner region of the pulverization chamber located inside the annular partition wall, and wherein a vertically-extending flow straightening blade is provided between said lower portion of the media guide member and an upper portion of the annular partition wall, and the media separation member is provided on the lower end of the lower portion of the media guide member.

A device and method for cleaning flowers and buds of plants of leaves and plant matter and particulate is provided. The buds are cleaned within a rotating drum having openings in a circular sidewall which rotates adjacent jets emitting gas. Freezing of the plant material and concurrent impacts from ice crystals formed by emitting gas, cleans the buds and flowers of unwanted plant material and particulate.

An agitator ball mill with a fluid circuit, which includes a grinding container and a casing container disposed around the latter uniformly spaced apart axially with a cavity formed between the containers. The fluid circuit is led at at least one flange through at least one flange lead-through introduced there, wherein a first opening of the at least one flange lead-through is constituted in a side wall of the corresponding flange lying orthogonal to the outer surface of the casing container.

Mixture of particles comprising a non-conducting or semi-conducting nucleus covered with a hybrid conductor coating and hybrid conductor chains located between the particles of the mixture to constitute a conductivity network, that is prepared by mechanical crushing. Due to a very good conductivity of the network, a low resistivity, a very good capacity under elevated current and/or a good density of energy, these mixtures of particles are advantageously incorporated in anodes and cathodes of electrochemical generators, resulting in highly performing electrochemical systems.

An agitator ball mill comprising a grinding chamber having a cylindrical wall, and further having a rotatably mounted agitator shaft extending into the grinding chamber and on which at least one agitator element is arranged inside the grinding chamber. The mill further comprises an inlet for supplying to the grinding chamber material to be ground and grinding bodies, an outlet for removal of the ground material, and an induction heater for the material to be ground located in the grinding chamber, the induction heater comprising an inductor and a susceptor. The at least one agitator element comprises a susceptor material which forms the susceptor of the induction heater, wherein the inductor comprises at least one coil which is arranged outside the cylindrical wall of the grinding chamber and encompasses the grinding chamber, and wherein the cylindrical wall of the grinding chamber consists of an electrically and magnetically non-conductive material.

Methods for reducing moisture content of alkaline earth metal carbonate may include introducing alkaline earth metal carbonate having a moisture content ranging from about 0.1% by mass to about 10% by mass into a primary crusher and operating the primary crusher to obtain alkaline earth metal carbonate particles having a top cut particle size d.sub.90 of 90 microns or less. The method may also include introducing the particles into a primary grinder and operating the primary grinder to obtain reduced-size alkaline earth metal carbonate particles having a median particle size d.sub.50 of about 60 microns or less. The method may further include introducing the reduced-size particles into a classifier mill and operating the classifier mill to obtain further-reduced-size alkaline earth metal carbonate particles having a median particle size d.sub.50 of about 12 microns or less, and a moisture content of about 0.15% by mass or less.
