| 20090189004 | COMMINUTING DEVICE WITH COUNTER-ROTATING ROTORS - A device for comminuting feedstock is provided that includes a cutting tool with a first rotor and at least one second rotor, each of which rotate around their longitudinal axis with an opposite rotation direction. Each rotor is provided with a number of cutting discs, which are arranged at an axial distance to one another. In this case, the cutting discs of the first rotor are located on gaps and with radial overlapping relative to the cutting discs of the second rotor. The cutting discs along their circumference have support surfaces for accepting cutting tools, whose cutting edges move past one another over the course of the rotation of rotors with the formation of a cutting clearance. For the positionally precise fixation of the cutting tool on the cutting discs, a positive fit is formed between the cutting tools and cutting discs, a positive fit groove running in the plane of the cutting disc is arranged in the common contact area, the groove in which at least one positive fit strip engages. | 07-30-2009 |
| 20100090044 | DEVICE FOR PROCESSING FEEDSTOCK - A device for processing feedstock, includes a housing surrounding a processing chamber in which a rotational rotor having processing tools and mounted on a drive shaft is disposed around an axis. The feedstock is fed to the processing chamber via a material inlet and removed from the device via a material outlet. To facilitate assembly and disassembly of the device and to retool, maintain and repair or clean the device, it is provided according to the invention that the housing includes a first end wall, a material element in the shape of a hollow cylinder or hollow truncated cone, and a second end wall which are detachably connected to each other to form the processing chamber. The connection can be made by axially acting clamps, which clamp the first end wall against the second end wall by clamping the casing element. | 04-15-2010 |
| 20100282881 | DEVICE FOR PROCESSING FEEDSTOCK - A device for mixing, grinding, drying, deagglomeration, crushing, or coating of feedstock with a rotor is provided, rotating around an axis within a housing, and a stator, fixed relative to the housing, encompassing the rotor with maintenance of a radial working gap. The rotor has rotor tools, which are distributed over its outer surface and whose active edges for crushing the feedstock work together with the stator tools on the inner circumference of the stator. In this regard, the feedstock is supplied in the carrier gas stream to the working gap. For effective processing of the feedstock, it is proposed according to the invention that in the outer surface of the rotor a plurality of indentations is introduced, whereby areas between two adjacent indentations form webs, which form the active edges of the rotor tools. | 11-11-2010 |
| 20100282886 | DEVICE FOR COMMINUTING INPUT MATERIAL - A device for comminuting input material, especially for fine and ultrafine grinding of input material, includes a rotor revolving around a shaft inside a housing, the rotor having a cylindrical or conical jacket surface. An annular gap is present between the housing and the jacket surface, the gap forming a comminution zone and the input material being introduced axially to it. To increase the economic efficiency of the device, it is provided that a plurality of first pin-shaped comminuting tools for comminuting the input material are disposed over the circumference of the rotor, wherein the tools are aligned with their longitudinal direction perpendicular to the jacket surface in the direction of the housing. | 11-11-2010 |
| 20100282888 | DEVICE FOR THE WORKUP OF INPUT MATERIAL WITH A ROTOR-STATOR SYSTEM - A device for processing free-flowing input material is provided that includes a rotor rotating around a shaft within a housing, the rotor being fitted over its circumference with rotor tools. Stator tools, permanently fixed to the housing, are arranged, which are disposed opposite the rotor tools allowing a working gap and interact with the rotor tools to process the input material. The stator tools are held in a holder, forming a tool unit. The tool units are made self-supporting over the length of the rotor and end sections of the tool units are fixed removably in respective clamping devices. | 11-11-2010 |

| 20080287277 | DEVICE FOR DEWATERING OF BULK OR FREE-FLOWING INPUT MATERIAL BY COMPRESSION - A device for dewatering bulk or free-flowing input material by compacting it is provided. The device has a housing arranged along an axis of rotation, which has an input area and a feed and compaction area following axially within a jacket pipe. In the housing, a coaxial drive shaft with circumferentially extending coils rotates, compacting the input material during transport from the input area through the feed and compaction area. In this process the residual water present in the input material is conducted through radial openings in the jacket pipe from the device. According to the invention it is provided that at least in a partial region the jacket pipe is provided with passages and inside the jacket pipe an inner pipe is arranged, which lies at least partially with its external circumference against the inner circumference of the outer jacket pipe and which at least in the area of the passages has passage openings that are several fold smaller than the passages in the jacket pipe. | 11-20-2008 |
