20160121333 | DEVICE AND METHOD FOR PROCESSING OF FEED MATERIAL - A device and a method for processing feed material that has a housing, a material supply channel and a material discharge. The housing is axially divided into a first processing zone in which a rotor rotating around an axis is situated, and a second processing zone which adjoins the first processing zone in the flow direction of the feed material. In order to perform different processing procedures in one device the feed material is subject to a process gas by arranging a hollow body in the housing, coaxially to the axis for the formation of the second processing zone, which outer circumference is radially situated opposite the inner circumference of the housing, and which features at least one port at the end that is facing the rotor. A process gas, which can be fed to the feed material through at least one port, is applied to the hollow body. | 05-05-2016 |
20160059239 | DEVICE FOR COMMUNICATION OF PROCESS FEED MATERIAL WITH UPSTREAM SIFTING - A device for the comminution of free-flowing feed material is provided that includes a housing enclosing a comminution chamber which contains a rotor that rotates around an axis, and has comminution tools over its circumference. A feeding device to transport the feed material to the comminution chamber in form of a gas-solid matter mixture, wherein the feeding device features a pneumatic sieve passage which uses the effect of gravity for removal of foreign particles from the feed material. In order to operate both the sieve passage and the device under optimal process parameters, the device features at least one inlet port for the supply of secondary air, wherein the at least one inlet port flows into the gas-solid matter mixture downstream of the sieve passage. | 03-03-2016 |
20140306046 | DEVICE FOR COMMINUTING FEEDSTOCK - A device for comminuting feedstock with a rotor which is disposed within a housing and rotates about an axis of rotation and is equipped over its circumference with comminuting tools. A ring disc is attached to front sides of the rotor in each case concentrically to the axis of rotation. The removal of the sufficiently comminuted material occurs via a screen deck extending over part of the rotor circumference. On axial front sides of the screen deck an arcuate sealing element following the outer circumference of the ring disc is disposed in each case, the element which to form a sealing gap in the plane of the ring disc lies radially opposite to the disc. The sealing effect of the sealing gap between the screen deck and rotor uniformly over the entire length is successfully achieved in this way. | 10-16-2014 |
20130134250 | TOOL UNIT AND CUTTING OR PUNCHING TOOL FOR A COMMINUTION DEVICE, AND A DEVICE EQUIPPED THEREWITH - A tool unit for a comminution device with a rotor-stator system is provided, in which comminution tools are detachably fastened to tool holders on a rotor circumference and work together with comminution tools located on the stator. In order to shorten the tool replacement downtimes of a device equipped with such a tool unit and to increase its profitability, the tool holder includes a first carrier section and a second carrier section, the rear sides of which sections detachably contact one another in a common contact plane, and on each of the mutually averted front sides of which is located at least one bearing surface for accommodating a tool. | 05-30-2013 |
