  • Method and apparatus for pneumatically conveying bulk material which does not flow readily
    Patent number: 8480336
    Abstract: The present invention relates to a process for pneumatically conveying a bulk material which does not flow readily in which an input device variably meters the bulk material into a lateral conveyor until it is partially filled, and then a mechanical conveyor, in combination with the simultaneous introduction of compressed gas into the lateral conveyor, empties the bulk material partially filling the lateral conveyor, rendering the bulk material conveyable.

  • Jet mill with integrated dynamic classifier
    Patent number: 7681814
    Abstract: The present invention relates to a jet mill for grinding and classifying material having an integrated dynamic classifier section connected to a conveying section to and from which a fine material and a material to be further ground are conveyed. The integrated dynamic classifier section of the present invention allows for the separation of a fine material from a material to be further ground. Furthermore, the present invention also includes a method of using such a jet mill having an integrated dynamic classifier section for grinding and classifying of material.

  • Method and apparatus for pneumatically conveying bulk material which does not flow readily
    Patent number: 7413388
    Abstract: The invention relates to a method and an apparatus for pneumatically conveying bulk material which does not flow readily, in which: bulk material is metered by means of one or more input device(s) (8) into a lateral conveyor (1); and the bulk material in the lateral conveyor is subsequently emptied via a transport line (19) wherein the metering of the bulk material into the lateral conveyor (1) is achieved by means of the input device(s) (8) and the emptying of the lateral conveyor (1) is effected with simultaneous action of a mechanical conveyor (9) in the lateral conveyor and inflowing compressed gas (17), with the mechanical conveyor (9) having a narrow clearance with respect to the lateral conveyor (1), so that the lateral conveyor is substantially emptied during the emptying process.
