A filter press having a plurality of stackable filter plate assemblies comprises at least one turbidity sensing module [] coupled to a first filter plate assembly [] within the plurality of stackable filter plate assemblies. The turbidity sensing module [] is generally positioned between a filtrate drain opening [-] communicating with a filter chamber [], and either a filtrate port [] or filtrate discharge tube [], in order to determine a level of turbidity of filtrate [] exiting said first filter plate assembly. Turbidity levels may be determined independently of turbidity levels of filtrate [] exiting other filter plate assemblies [] within the filter press. When turbidity levels reach a predetermined threshold, and alarm [] is activated, which informs an operator of the need to replace a filter cloth associated with the affected filter plate assembly [

Turbidity sensing filter apparatus, systems, and methods thereof

A roller mill for grinding particulate material such as for example cement raw materials, cement clinker and similar materials, said roller mill comprising a mill housing enclosing a grinding table and a set of rollers rotatable about a vertical shaft. The set of rollers are configured for interactive operation with the grinding table and comprising a number of rollers each rotating about a roller shaft which is connected to the vertical shaft via a hinged connection with a center of rotation which allows a free circular movement of the roller in upward and downward direction in a plane comprising the centerline of the roller shaft. The center of rotation of the hinged connection in a vertical plane is located under the centerline of the roller shaft. The grinding table is rotatable about the vertical shaft and the roller mill may include mechanisms or devices that are sized and configured to introduce gases into the mill housing and may also include mechanisms or devices configured to allow for continuously diverting ground material suspended in gases out of the mill housing.

Roller mill for grinding particulate material

Described is a method as well as an apparatus for incineration of combustible waste during the manufacture of cement clinker by which method the waste is introduced via a waste inlet () and supported on a supporting surface () incorporated in a separate compartment (), where the waste being actively transported, while simultaneously subjected to incineration, through the compartment to its outlet (), where the hot exhaust gases produced in connection with the incineration of the waste being vented to the preheater system for heating the cement raw meal, and where the slag generated during the waste incineration process being extracted from the compartment (). The method and the apparatus are peculiar in that exhaust gases containing NOx are introduced to the compartment ().

Method and apparatus for incineration of combustible waste

A roller mill for grinding particulate material such as cement raw materials, cement clinker and similar materials includes a mill housing, a substantially horizontal and stationary grinding table, and a number of rollers each rotating about a roller shaft which is connected to a rotatable vertical shaft centrally positioned relative to the stationary grinding table. The rollers are configured for interactive operation with the grinding table. The grinding table is stationary. The roller mill also includes at least one first device utilized for introducing gases into the mill housing and at least one second device for continuously diverting ground material suspended in gases out of the mill housing. As a consequence hereof, the process for the roller mill with a stationary grinding table will be continuous and the diameter of the grinding table will not be subject to limitations.

Roller mill with application of gas

A roller mill includes a substantially horizontal grinding table, at least one roller operating interactively therewith which is configured for rotation about its centerline by means of a roller bearing and being connected to a roller shaft. The roller mill also includes a force device for at least partial absorption of an axial force originating at least from the roller and acting in the longitudinal direction of the roller shaft. The force device comprises a first part mounted on a machine component which is stationary relative to the longitudinal direction of the roller shaft and a second part mounted on a machine component rotating about the centerline of the roller and co-rotating therewith. The first and second parts comprise opposing pressure surfaces which both extend substantially perpendicular to the longitudinal direction of the roller shaft and form between them a compartment. The pressure surface on the first part is oriented in the opposite direction to the axial force acting in the longitudinal direction of the roller shaft and the pressure surface on the second part is oriented in the same direction as the axial force acting in the longitudinal direction of the roller shaft. An apparatus configured to introduce a pressurized viscous medium into the compartment between the opposing pressure surfaces is also included.

A roller mill () for grinding particulate material such as cement raw materials, cement clinker and similar materials has a substantially horizontal grinding table () and a set of rollers revolving about a vertical shaft (). The set of rollers includes a number of rollers () rotating about respective roller shafts () which are connected to the vertical shaft () via a hinged connection () which has a bearing shell () and a bearing journal () resting therein. The hinged connection () allows a free arcuate movement of the roller () in an upward and downward direction in a plane including the centerline () of the roller shaft. The set of rollers () is configured for interactive operation with the grinding table (), and the bearing shell () of the hinged connection () has a diameter which exceeds that of the bearing journal () resting therein by a factor of at least 1 percent.
