Abstract: A dryer for drying a liquid feed into a powder comprises a drying chamber defined by a chamber wall including a bottom wall portion; a feed inlet for receiving the liquid feed and dispersing particulate feed into the drying chamber; at least one air inlet for entering drying air into the drying chamber; and at least one drying chamber outlet for dried powder and/or spend drying air from the drying chamber. The feed inlet comprises a decanter centrifuge with an axis of rotation; a first axial end; a second axial end; and a solid phase outlet at the first axial end.

Abstract: A solid-bowl screw centrifuge has a rotatable drum with cylindrical and conical portions. At least one solid discharge is arranged in the conical portion of the drum. A screw is arranged in the drum and can rotate at a differential speed in relation to the rotatable drum. At least two drum bearings are used for mounting the drum in a housing and at least one screw bearing is used for mounting the screw in the drum. The drum and the screw mounting are designed in the region of the conical portion or the dry zone in such a way that solid matter is transported with the aid of the screw up to a solid-discharge drum cover, which forms the termination of the conical portion in the axial direction of the drum, in order to leave the drum through multiple openings in the solid-discharge drum cover.

Abstract: A solid bowl screw centrifuge includes a housing and a rotor rotatably mounted in the housing. The centrifuge has a rotatable drum having an axis of rotation, the drum having a cylindrical section having a length L1 and a conical section having a length L2. The centrifuge also has a first inlet for feeding a suspension to be processed into the drum and a liquid outlet arranged in the cylindrical section of the drum and a solids outlet arranged in the conical section of the drum. A screw is arranged in the drum and rotatable at a differential speed relative to the rotatable drum, the drum and the screw together forming the rotor. The centrifuge also a second inlet for supplying an additive to a solid phase within the drum.

Abstract: A solid bowl centrifuge includes a rotatable drum having a cylindrical portion with length L1 and a conical portion with length L2, which, when added, give the length LT of the drum. A screw is arranged in the drum and is rotatable relative to the rotatable drum with a differential speed. At least two drum bearings for supporting the drum in the housing are spaced apart with a spacing LL. A spacing LL of the drum bearings for supporting the drum relative to one another is less than the length LT of the drum.

Abstract: A solid-jacket screw centrifuge is disclosed. The centrifuge has a rotatable drum with a horizontal axis of rotation which encloses a bowl with a rotatable screw, an inlet for introducing material to be centrifuged into the bowl, at least one liquid and at least one solid discharge, where at least the solid discharge is assigned a non-rotatable housing surrounding it, at least radially bounding a discharge chamber, where the discharge chamber is designed as a drying chamber for the solid matter and has axial walls and one or more walls in the radial direction. The housing extends axially parallel to the axis of rotation at most into the conical region of the drum or the screw.

Abstract: A centrifuge includes at least two centrifugal drums, each drum including a disc stack and each drum being rotatable about first and second axes of rotation. The first axis of rotation extends through a center of gravity of and is within each drum. The second axis of rotation is situated outside each drum.

Abstract: A machine (1) is serving the purpose of comminution for example domestic garbage, refrigerators, tires, furniture, carpets, mattresses, stubs, demolition timber and similar materials. The machine has a funnel (2) for accommodating the waste, a cutting table (4) placed at the bottom of the funnel with at least one set of fixed, parallel lower knives (9a,b) which mutually are separated by openings (10a,b) through the table, at least one rotatable axle (5a,b) of a drive unit (7) which axle is placed above the cutting table into a direction, which extends perpendicular to the lower knives, and a number of disc-shaped upper knives (8a,b) fixed to the axle, each of which knives is provided with a number of teeth (13a,b) and partly extends down into each their opening of the table. The lower knives are running into a direction, which intersects the axis (18) of the axle or an area around this. Thereby it is obtained that the teeth of the upper knives will have angle of action of about 90.degree.
