  • Patent number: 9751088
    Abstract: The rotational speed of the drum of an ore mill may be controlled variably over time. By rotating the drum during a first time interval at high speed, especially hard or dense particles are broken up by tumbling. At the same time, the discharge characteristics of the mill are adversely affected. In a subsequent second time interval, the drum is rotated at a slower speed, and the material is discharged more effectively, whereas the tumbling movement inside the mill is not achieved. The combination of said different modes of operation within short time periods in continuous operation may improve both the comminution as a result of a tumbling motion of the material and also the discharge of the ground material. By regulating the rotational speed with different target values within short time windows, different requirements for the movement behavior of the material to be ground and for the discharge characteristics of the ground material can be simultaneously optimized.

    Abstract: Materials in battery and electrochemical cells are separated in a form suitable for recycling by employing froth flotation techniques. Bulk materials, such as casings, are removed from converted battery scrap and the resultant pulp is subjected to froth flotation. Froth flotation agents, including frothers, collectors and/or depressants, are used to manipulate the hydrophilic and hydrophobic nature of the materials in the scrap. Hydrophobic materials are entrained in the air bubbles of the froth and float out of the froth flotation vessel while those that are hydrophilic remain in the vessel, thereby separating battery grid materials without resort to pyrometallurgical, energy intensive or other environmentally undesirable processes.

    Abstract: The invention concerns a method and an arrangement for the output of mineral material from a drum mill having a horizontal rotation axis, a sieving wall at its end wall, material can leave through the sieving openings in to pulp-lifting chambers, limited by the sieving wall, the end wall, a limiting wall, and limiting walls that lead towards an output cone, whereby material in the pulp-lifting chamber is emptied down towards the output cone when the pulp-lifting chamber is an upper part of a revolution. In order to increase the rate of revolution, material that does not reach the material output cone is collected in a material collection pocket which carry the material at a level radially closer to the rotation axis than the inner limiting wall, whereby collected mineral material leaves the material collection pocket during, a subsequent revolution.

  • Publication number: 20140034762
    Abstract: An asphalt roofing material recycling system and method is used to recycle new and used (post consumer) asphalt materials, such as asphalt shingles, rolled roofing and tar paper that may include granules, fibers or other particles. The asphalt material, which may be in bundles, is broken up and separated and then provided to a cooled recycling vessel. Dry ice is added along with the asphalt material to be recycled. The dry ice removes any moisture present and super-cools the material making it brittle and easier to chip and break up. The recycle vessel includes a number of high speed shippers having tulip hear chipping teeth as well as one horizontal mixer element which stirs the material and makes sure all material is ground. The resulting course to fine powder can be separated by screening and stored as power or compressed into bricks or briquettes.

  • Publication number: 20140014748
    Abstract: A method and system for processing biomass material from harvest to pelletizing includes a continuous shredding stage and grinding stage to reduce the size of the material. A fan pulls air through the shredder and the grinder to assist the movement of the biomass material through the shredder and the grinder. Due to the light weight of the biomass material, the material is transported between the shredding and grinding stages mechanically and pneumatically by a combination auger with air assist. The biomass material may include agricultural residues, such as corn stover. The process and equipment eliminates or minimizes damage to the carbohydrates in the biomass so as to maintain pre-grinding cellulose and hemi-cellulose levels.

  • Patent number: 8623929
    Abstract: In a method and equipment for conditioning low-metal scrap high in plastics, which contains at least partially scrap high in plastics from shredder processes, especially of scrap vehicles, the method includes: splitting up ferromagnetic components from the scrap that is high in plastics; separating a first raw sand fraction from the scrap high in plastics that has been reduced in metals; reducing in size the fraction high in plastics that remains after the isolation of the first raw sand fraction; separating a second raw sand fraction after reducing in size the remaining fraction high in plastics; and splitting up the remaining fraction, that is high in plastics, into a light fraction and a heavy fraction. The equipment has the appropriate device for carrying out the individual method steps.

  • Publication number: 20130277466
    Abstract: A method of protecting a roller crusher, having two rollers separated by a gap, from uncrushable objects is disclosed. The method comprises the steps of: detecting an uncrushable object in an in-feed stream of material, opening a gap between said rollers to a by-pass width, which is significantly larger than an operational width, such that said uncrushable object is permitted to pass through said gap, restricting an in-feed to said gap, such that material is fed to said gap at a restricted in-feed rate, determining that said uncrushable object has passed through said gap, reducing said gap to said operational width, and opening said in-feed to said gap, such that material is fed to said gap at an operational in-feed rate. A roller crusher having a protective system for protecting the roller crusher from uncrushable objects is also disclosed.
