A method for producing a powdered starting material, which is provided for production of rare earth magnets, including includes the following steps: pulverizing an alloy, including at least one rare earth metal, wherein a powdered intermediate product is formed from the alloy including the at least one rare earth metal, and carrying out at least one classification aimed at particle size and/or particle density for the powdered intermediate product. A fraction of the powdered intermediate product, which is formed by the at least one classification, is used for fabrication of rare earth magnets. Furthermore, at least one dynamic classifier is provided, implementing at least one classification directed at particle size and/or particle density for the powdered intermediate product and thereby separates the fraction from the powdered intermediate product, which forms the starting material for manufacturing rare earth magnets.

A crushing apparatus includes a tank including a first aperture and a second aperture, a first blower around the first aperture, a grinder disposed within the tank, a separating device including a first hole connected to the second aperture, and a second hole, and a second blower disposed around the second hole.

Monolithic dust separation devices are disclosed to enable separating and collecting dust particles. The devices include a vacuum port and a cyclone chamber that are connected by a tube between the vacuum port and an upper end of the cyclone chamber. On the cyclone chamber there is an input port for connecting to a flexible hose for ingesting the dust particles. The devices also include a dust receptacle having a top upper surface and a port cover on a port formed in the upper surface for emptying the receptacle of collected dust particles and a lower portion of the dust receptacle that is integrally formed into the upper surface of the dust receptacle. The top upper surface slants downward from the cyclone chamber to the port cover.

A wastewater purification system that uses mechanical and chemical processes to separate contaminants from municipal and other sanitary wastewater, concentrates the resulting sludge for disposal, and purifies the resulting product water for reuse as irrigation water, potable water or for disposal. The wastewater purification system can be scaled from a mobile system mounted on a skid or a tracker trailer to a large municipal wastewater treatment system. The wastewater purification system can include a hydrocyclone feeding a flotation tank. Flocculant is added upstream from the hydrocyclone after air injection by a Venturi air injector or similar device. Coagulant is added before the air injection. A dose of flocculant is added after the hydrocyclone within the vortex of the hydrocyclone and before the wastewater exits near the top of the flotation tank.

One illustrative system disclosed herein includes a separator vessel that is adapted to separate solids particles from a flow of a multi-phase fluid, a differential pressure sensing system that is adapted to measure a differential pressure of a column of the multi-phase fluid in the separator vessel and a control system that is adapted to determine at least one of a level, volume or weight of the separated solids particles within the separator vessel based upon at least the measured differential pressure of the column of the multi-phase fluid in the separator vessel.
