Abstract: Fine particle coal is beneficiated in specially designed dense medium cyclones to improve particle acceleration and enhance separation efficiency. Raw coal feed is first sized to remove fine coal particles. The coarse fraction is then separated into clean coal, middlings, and refuse. Middlings are comminuted for beneficiation with the fine fraction. The fine fraction is deslimed in a countercurrent cyclone circuit and then separated as multiple fractions of different size specifications in dense medium cyclones. The dense medium contains ultra-fine magnetite particles of a narrow size distribution which aid separation and improves magnetite recovery. Magnetite is recovered from each separated fraction independently, with non-magnetic effluent water from one fraction diluting feed to a smaller-size fraction, and improving both overall coal and magnetite recovery.

Abstract: The slag that is formed in garbage and waste incinerators is cleaned of coarse material and iron directly after the slag outlet (1) from the incinerator. Separation into two fractions takes place after coarse cleaning, in a fractionating unit (6). One of the fractions contains all the particles that are smaller than 2 mm. At the same time, the dust is separated by a suction system (14). Dust and particles smaller than 2 mm contain practically all the soluble harmful substances and have to be processed and stored observing special precautions, or dumped. The remaining, cleaned slag is dry, and can be used as construction material. The process and the apparatus avoid the use of a water bath, so that no energy is needed for drying.

With the crushing, the dust produced is pneumatically gathered and filtered out (22,9). A non-metal fraction (A) as well as a magnetic (B) and non-magnetic fraction (C) are produced separately as granules and dust. The metal fractions (B, C) are suitable for further pyrolysis-free, wet chemistry and/or electrolytic separation. The non-metallic fraction is capable of being precipitated. The method is noted for its minimal energy consumption and high environmental compatibility.

Abstract: A steel can shredding/delabeling system processes post-consumer steel cans, taken from a solid weight stream, into a densified product suitable for detinning. The steel cans are transported and fed into a surge hopper that feeds cans into a shredder. The surge hopper is designed to maintain a continuous feed to the shredder to optimize shredding efficiency. As the steel cans pass through the shredder, they are transformed into shredded, densified steel particles with the paper labels removed and reduced to paper fines. This mixture of shredded cans and paper fines is transferred by conveyor to the top of a multi-pass aspirator. The aspirator utilizes an upward air flow within a column of the aspirator to separate the materials on the basis of their terminal velocities in air. The mixture free falls down a series of cascades, while being subjected to the upward flow of air.

Abstract: A screening machine has a rotating screening drum for screening dirt or other material to a desired size through the screen openings, and is made so that it reduces clogging of the screen, even when rocks, dirt clods, and moist dirt is being screened.
