A kiln for firing cement clinker may include a tubular rotary drum that can be rotated about its central axis. The tubular rotary drum may have a discharge end at which the cement clinker leaves the kiln. A protective segment may be attached at the discharge end and may have an outward-facing wear surface and an inward-facing cooling surface. The kiln may include a cooling device for generating a cooling air flow that flows along the inward-facing cooling surface of the protective segment. The inward-facing cooling surface can include profile bodies that are pin-shaped. The profile bodies may be uniformly spaced apart, parallel to one another, and/or present over 20% to 60% of the inward-facing cooling surface.

The system according to the invention for thermally processing lumpy solid material substantially comprises a preheating device, a furnace and a separation or classification device which is arranged therebetween and which has a coarse material outlet connected to the furnace and a fine material outlet. The furnace and the preheating device are connected to each other by means of a gas/solid material line which is arranged so as to be inclined relative to the vertical, the furnace exhaust gases being introduced at the end of the gas/solid material line at the furnace side and the preheated solid material being supplied at the end at the preheater side. The separation or classification device is connected to a bypass line which branches off from the gas/solid material line so that at least a partial amount of the preheated solid material can be branched off via the bypass line by means of gravitational force and can be supplied to the separation or classification device.

A roller mill for comminuting brittle grinding stock comprises at least one grinding roller constructed as a loose roller and rotatable about an axis and interacting with a counter-surface such that grinding stock is comminuted between the grinding roller and counter-surface. Horizontally slidable bearing blocks bear the grinding roller and are guided in a frame rotatably about a vertical bearing axis. A pressing device applies an adjustable grinding pressure to the grinding roller via the bearing blocks. At least two resilient compensation elements are associated with each bearing block in order to compensate a skewed position and/or deflection of the grinding roller. The compensation elements are arranged between the frame and the bearing blocks, and, in the plan view of the roller mill, are arranged tangentially to a circle around the vertical bearing axis or constructed in a circular arc around the vertical bearing axis.

Roller mill for comminuting brittle grinding stock

The roller grinding mill for comminuting brittle grinding stock includes at least one grinding roller which co-operates with a counter-face in such a manner that the grinding stock is comminuted between the grinding roller and the counter-face and a pressing system for applying a force to the grinding stock via the grinding roller. The pressing system includes: at least one hydropneumatic store and at least one dual-articulation actuating cylinder. The dual-articulation actuating cylinder is connected to the hydropneumatic store and has two pistons and a housing which acts as a coupling rod.

Grinding mill with dual articulation actuation cylinder

The invention relates to a roller mill having a mill housing, a mill path which is supported so as to be rotatable about a mill axis inside the mill housing, and at least one mill roller which can be rotated about a mill roller shaft and which is engaged with the mill path in terms of rolling action. There is further provided a pivot lever which is for rotatably retaining the mill roller and which has a pivot shaft arranged parallel with the mill roller axis and which is supported outside the mill housing. The pivot lever is further in operational contact with a hydropneumatic resilient system in order to adjust the pressing pressure of the mill roller. The pivot lever is supported outside the mill housing with spacing therefrom in such a manner that the forces which are produced by the hydropneumatic resilient system are dissipated into the mill foundation directly or via pillars.

Roller mill

The invention relates to a rotary tube mill and to a method of comminuting lumpy mill feed material, in which at least a first and a second grinding chamber as well as a co-rotating partition disposed between the grinding chambers are used. The material ground in the first grinding chamber is divided in the partition into first and second part-quantities of mill feed material, whereby at least a part of the second part-quantity of mill feed material proceeds into the second grinding chamber and at least the first part-quantity of the mill feed material is discharged separately from the tube mill.

A chamber having a discharge base discharges an oversize fraction of a material and a fine fraction of the material separately from the chamber. The discharge base for the chamber for the heat treatment of the material is capable of separating the fine fraction of the material from the oversize fraction of the material. The discharge base has a plurality of conveyor elements which are movable to and fro for the discharge of the oversize fraction of the material. The discharge base is also provided with separator openings for separating out the fine fraction of the material. The conveyor elements are of bar-shape construction and are disposed in parallel to one another on the discharge base to be moveable in the direction of their longitudinal extent, and the separator openings are formed by longitudinal gaps between the conveyor elements.
