Abstract: A method of measuring one or more motion parameters of a main shaft in a gyratory or cone crusher is disclosed. Signals are directed from a stationary sensor means located apart from the main shaft to one or more signal reflective surfaces situated on a target located on or adjacent to an upper portion of the main shaft. The target rotates and otherwise moves in unison with the movement of the main shaft. From the elapsed time the distances from the sensor the reflective surfaces on the target are determined. Analyzing the distances over time will yield information on the movement of the main shaft.

Abstract: Described is a roller mill (1) for grinding particulate material such as cement raw materials, cement clinker and the like, said roller mill (1) comprising a grinding table (3), a set of rollers rotatable about a vertical shaft (5), said set of rollers comprising a number of rollers (4) rotating about separate roller shafts (6), which are connected to the vertical shaft (5), and a nozzle ring (7) for directing gases into the roller mill (1), said nozzle ring (7) enclosing the grinding table (3), and means (8) for regulating the gas flow through the nozzle ring (7). The roller mil is peculiar in that at least some of the regulation means (8) are arranged to rotate together with the set of rollers. In order to ensure optimum regulation of the gas flow through the nozzle ring in relation to the uneven load imposed by the material, thereby optimizing the roller mill operation in terms of capacity, grinding efficiency and energy consumption, the position of at least some of the regulation means for regulating the gas flow through the nozzle ring relative to the set of rollers remains the same at all times. The gases which are introduced into the mill via the nozzle ring will, therefore, always exhibit the same flow pattern in relation to the set of rollers.

Abstract: The invention relates to a roller mill for grinding solid material such as cement raw materials and similar materials, said roller mill comprising a substantially horizontal grinding table and at least two rollers which are configured for interactive operation with said grinding table, wherein at least one of said rollers rotates about a stationary shaft connected to a rocker arm pivotally connected to a mill stand which substantially is situated outside said grinding table and therefore does not utilize a mill stand and the remaining rollers do not utilize a mill stand. According to the invention the number of rollers, and thereby the capacity of the mill is increased without introducing more mill stands.

Abstract: A separator device (100) includes a separation chamber (107) defined at its lower end by a fluidization fluid panel (111). The separation chamber (107) receives incoming slurry (113) via a slurry inlet (102). The separator device may be characterised in that means (122) for supplying pre-sheared aerated fluidization fluid is provided above the fluidization fluid panel (111). The means (122) for supplying pre-sheared aerated fluidization fluid includes a novel sparger (119) comprising a flexible perforated membrane which is configured to supplementally shear the pre-sheared aerated fluidization fluid and uniformly distribute microbubbles (129) throughout the separation chamber (107).
