Abstract: System having an apparatus (10) for shredding hygiene products (12), which operates within a revolving device (22).

Abstract: Underwater mineral dressing units, systems and methods are provided. Material is milled in a water-immiscible liquid which is heavier than water and lighter than the product material. Gangue material is removed by the milling and floats on the water-immiscible liquid to be removed without further processing. Product containing material sinks and is further milled to remove additional gangue material, until the required level of extraction is achieved. Cascades of milling rolls in the water-immiscible liquid allow ever improving extraction of the product material. The rolls are arranged to regulate material flow through the system to remove floating gangue while directing sinking product material to further processing.

Abstract: Disclosed is a mixing, milling, and aeration apparatus for the digestion of metal ore with bacteria. It includes a tank and a center post therein. At least one mixing blade extends radially from the center post. At least one roller is supported by a mixing blade, where each roller is configured to roll about the center of the tank while applying a crushing force to solids within the tank. At least one gas distributor, supported by a mixing blade, defines a plurality of holes through which gas is distributed to encourage mixing of the contents of the tank, to encourage distribution of oxygen through the contents, and to discourage fouling of the bottom of the tank and the rollers.

Abstract: A wet ball mill method for fabricating copper/indium/gallium/selenium (CIGS) nanoparticles, comprising an individual milling process, a homogeneously mixing process, a primary milling process, and an advanced milling process, wherein in the individual milling process, the individual particles or compound particles including copper, indium, gallium and/or selenium are milled to the individual milled materials with a particle size 500 nm to 600 nm; in the homogeneously mixing process, the individual milled materials are mixed to a mixed homogenate; in the primary milling process, the mixed homogenate is milled to the primary milled materials with particle size 100 nm to 200 nm; and in the advanced milling process, the primary milled materials are milled to the advanced milled materials with particle size less than 50 nm which are the CIGS nanoparticles for fabricating the absorption layer of CIGS solar cell.

Abstract: The present invention provides an apparatus for dispersing pigment in a water-based or oil-based intermediate mixture for producing a coating composition comprising a mixer and a dispersing device, the mixer having a vacuum pump and capable of conducting a primary mixing of a pigment component and resin-containing liquid medium to form an intermediate mixture, the dispersing device capable of conducting the secondary mixing of the intermediate mixture, the mixer and the dispersing device being connected by pipes to form a circulation channel for the intermediate mixture, one of the pipes being provided with a seal-less pump, the intermediate mixture capable of circulating between the mixer and the dispersing device through the circulation channel.

Abstract: In a waste pulping apparatus, an impeller assembly comprises a rotating blade for pulping solid waste to form a slurry, the rotating blade having an axis of rotation, a base and a plurality of ears that axially extend away from the base. The impeller assembly also includes a sieve ring having axially opposed first and second ends, an inner cylindrical surface and an outer cylindrical surface, where the sieve ring encircles the base of the rotating blade at the first end so that a portion of the ears are radially spaced inside the inner cylindrical surface so that the ears rotate within the sieve ring. A plurality of pumping vanes are also provided for pumping the slurry, where each pumping vane has a pumping surface that rotates radially outside the outer cylindrical surface of the sieve ring. Preferably, the pumping vanes can be easily changed to allow for various head condition while providing a predetermined pumping capacity.

Abstract: A cone crusher includes a main frame having a chamber for rotatably receiving a eccentric housing, the housing includes an eccentric bore and a peripheral wall having different thicknesses for increasing the stone crushing effect. A inner bushing is received in the eccentric bore of the housing and includes an eccentric orifice for receiving stones to be crushed and a peripheral wall having different thicknesses for increasing the stone crushing effect. The inner bushing may be rotated relative to the housing, and a key may selectively securing the inner bushing to the housing.

Abstract: An apparatus is provided for dispersing solid particles carried in suspension in a liquid medium. The apparatus includes a mounting frame, a rotatable agitator shaft connected thereto, a drive assembly carried thereby for rotating the agitator shaft, and a roller-stator assembly carried by the mounting frame. The roller-stator assembly includes a roller assembly and a stator assembly. The stator assembly includes a plurality of stator support rods extending from the mounting frame and a stator ring attached to the stator support rods. The roller assembly is connected to the agitator shaft and is positioned within the stator ring. The roller assembly includes a plurality of upper and lower roller support portions which form pairs and each of which has roller positioned therebetween which is rotatable with respect to the pair and with respect to the stator ring.
