An example method for operating a plant, which has at least one assembly with a rotating surface that wears to an increasing extent during the operation of the plant, may involve evaluating a wear state of the rotating surface of the assembly. Based on the wear state of the rotating surface, a manner in which the plant is operated may be modified to prolong the running time of the assembly until, for instance, a next-scheduled service or maintenance interval. The modified manner of operating the plant may be adapted to the wear state of the rotating surface. Several examples of such modifications include changing a quantity of water sprayed onto material to be comminuted, changing a quantity of grinding additive added to material to be comminuted, and/or changing a contact pressure of a grinding roll of the assembly.

The separation according to the invention of a material-laden hot gas stream substantially consists of the following method steps:

Method and system for separating a hot gas flow that is charged with material and method for processing oil shale material

The industrial oven according to the invention has a rotary pipe and a fixed material supply device which is connected in the region of a front-face opening of the rotary pipe, there being provided between the rotary pipe and the material supply device a sealing arrangement which comprises a gas seal which is delimited from the operating chamber of the rotary pipe acted upon with material by at least a first gap between the rotary pipe and the material supply device. The sealing arrangement further has an annular chamber which is provided between the first gap and the gas seal and which has a discharge opening which is connected to the operating chamber. A lifting device is further provided in the annular chamber in order to lift out of the operating chamber material which has become introduced into the annular chamber through the first gap and to convey it back to the operating chamber through the discharge opening.

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 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.

In this tiltable supporting roller bearing according to the invention for supporting a rotary drum there are provided a freely rotatably mounted supporting roller and an appertaining bearing structure which is tiltably supported with respect to a stationary foundation plate with the aid of easily shifted support bearings which are arranged inclined against one another in such a way that the point of rotation of the line of contact between the supporting roller and the riding ring of the rotary drum lies with the vertical central axis of the supporting roller. With a particularly simple and reliable design, this construction makes it possible to compensate for skewing of the rotary drum riding ring and at the same time markedly to reduce or largely avoid undesirable consequences of the axial forces resulting from longitudinal movements of the rotary drum.

Tiltable supporting roller bearing

The invention relates to a rotary drum with relatively large dimensions, the shell of which is supported by means of riding rings each on a pair of supporting rollers of a supporting roller stand. For this purpose the rotary drum shell merely bears two riding rings which are attached so as to be fixed against rotation and which are supported on two supporting roller stands of which at least one simultaneously forms the rotary drive arrangement for the rotary drum in the form of a friction drive. This produces a combination of features by means of which the mounting of the rotary drum is statically determinate and can be driven reliably in an extremely simple manner.
