Abstract: Disclosed is lubrication for a slow-running two-stroke engine, especially marine diesel engines. The lubrication uses Swirl Injection Principle by locating the lubricant injectors closer to the TDC than ? of the full stroke of the piston, which is closer than in typical marine diesel engines. This can be achieved by reconstructing cylinder liners or by adding new mounting holes to the cylinder. In case that such reconstruction is not possible, an improvement of SIP principles can also be achieved by directing the spray towards the TDC or to a location on the cylinder liner closer to the TDC as compared to the location of the SIP valves, for example under an angle of more than 30 degrees or even more than 60 degrees when measured from a plane normal to the cylinder axis.

Abstract: 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).
