A roller press (1) is described for grinding of particulate material such as cement raw materials, cement clinker and similar materials, which roller press (1) comprises two oppositely rotating rollers (2, 3) forming between them a roller gap (4) and a co-rotating annular disc (5), which in concentric manner is attached to an end surface (6, 7) of one of the rollers (2) by means of a number of resilient attachment elements (8) and being movable in the direction of the roller axis, where the outer diameter of said annular disc (5) is greater than the diameter of said one of the rollers (2), hence the annular disc (5) in the area of the roller gap (4) extends toward the other roller (3), thus covering at least part of the roller gap (4). The roller press (1) is peculiar in that the inner diameter of the annular disc (5) is smaller than the diameter of the roller (2), to which it is attached, thus overlapping the end surface (6, 7) of said roller (2), and that the resilient attachment elements (8) are evenly distributed over the circumference of the annular disc (5) and provided with spaces or openings (10) there between.
It is hereby obtained that the annular disc (5) does not get stuck by material to be grinded or destructive forces damaging construction parts are not accumulated. This is due to the fact that material in the roller press (1) according to the invention is allowed to escape from the area between the annular disc (5) and the roller (2) to which it is attached.

Method and device for the continuous gravimetric metering of flowing materials for burner systems
A method for the continuous gravimetric metering of flowing materials for burner systems, in which the instantaneous mass flow is determined and metering occurs by means of a metering unit can be achieved by means of determination of the type of flowing material. The instantaneous heat output for the flowing material is determined from the type of flowing material and the heat capacity thereof and the mass flow determination. The output from the metering device is regulated to match the set feed rate, depending on the instantaneous heat output. In addition, a device for the continuous gravimetric metering of flowing materials for burner systems comprises a metering unit by means of which the flowing material can be metered. Also provided is a material recognition system for determining the type of the flowing material, an arithmetic unit for determining the instantaneous heat output of the flowing material and a metering controller by means of which the output from the metering unit is regulated to match the set feed rate, depending on the instantaneous heat output.

a) which are suspended on a supporting element (15) provided in the area between the cyclone housing (1) and the discharge duct (5). The cyclone separator is peculiar in that it comprises a number of carrying means (17) which are evenly distributed and fixed to the inner side of the cyclone housing (1) and/or the discharge duct (5), and in that the supporting element (15) comprises an annular disc which is loosely fitted on top of the carrying means (17) and having an outer diameter which is smaller than the inner diameter of the cyclone housing (1) and/or the discharge duct (5) so that a clearance (18) is provided between the annular disc (15) and the cyclone housing (1) and/or the discharge duct (5). Hereby is obtained a significant reduction in the heat transmission from the supporting element to the cyclone housing and/or the discharge duct so that the radial temperature gradient in the supporting element is reduced with an approximately uniform temperature over the radial cross section of the element. Hence the thermal stresses in the supporting element will be substantially reduced. This is mainly ascribable to the reduction in the contact area between the supporting element and the cyclone housing and/or the discharge duct.
