Abstract: A description is provided of a seal for preventing harmful material passing through a gap (3) between two machine elements (4,5) with said seal comprising two sealing parts (1,2) where at least one of the sealing parts (1) is fixed to one of the machine elements (5) and being configured for rotational operation together with said machine element (5) and where at least one of the machine elements (5) is configured for a movement back and forth in its axial direction relative to the other machine element (4). The seal is characterised in that the sealing part (1) being configured for rotational operation is provided with at least one helical thread (6) and in that one of the sealing parts (2) forms a casing (2a,2b,2c) around a portion of the other sealing part (1) and in that at least a portion of the helical thread (6) is located inside the casing (2a,2b,2c). In this way material (e.g. harmful dust) is restricted from passing through the gap between the two machine elements regardless of the fact that both machine elements perform a rotational and translatory movement relative to each other. The rotating sealing part with the helical thread ensures that most of the material coming into contact with the seal will be thrown away from the gap even when a significant relative axial displacement between the machine elements takes place.

Abstract: The invention relates to a wear-resistant roller for crushing of particulate material, such as crude ore for use in the cement or minerals industry comprising a roller body, a wear surface on the roller body. The wear surface comprises welding beads comprising a primary fraction of carbide material and a secondary fraction of material selected from the group consisting of Nickel, Nickel alloys, mixtures of Nickel and Nickel alloys and mixtures of Nickel containing refractory hard materials, Cobalt, Cobalt alloys, mixtures of Cobalt and Cobalt alloys and mixtures of Cobalt containing refractory hard materials. Furthermore, the welding beads are welded to the roller body in an overlapping manner such that two neighbouring welding beads comprise an overlapping volume and a non-overlapping volume, the overlapping volume being an intersection volume between the two neighbouring overlapping welding beads, and the fraction of carbide material being higher in the overlapping volume than in the non-overlapping volume such that the overlapping volume has a higher wear resistance compared to the non-overlapping volume having a lower wear-resistance. Also the invention relates to a method of forming such a wear surface on a roller body.

Abstract: A description is provided of a cooler (1) for cooling hot particulate material which has been subjected to heat treatment in an industrial kiln such as a rotary kiln (3) for manufacturing cement clinker, said cooler (1) comprising a grate (21) for receiving and supporting hot material from the kiln, at least one cooling gas duct (28) which is connected to slots (20) in the grate (21) for introducing cooling gases into the hot material and a compressed air system (25, 26) for injecting compressed air into the material on the grate (21). The cooler is characterized in that it comprises flow restricting means (31) which are provided in the cooling gas duct (28). It is hereby obtained, without using mechanically movable components that only a very limited amount of the compressed air which is injected into the material on the grate is allowed to pass through the cooling gas duct. This is due to the fact that the flow restricting means, as a consequence of the pressure conditions prevailing immediately under the grate when compressed air is injected will operate as a non- return valve which will substantially prevent compressed air from passing down through the cooling gas duct.

Abstract: Described is a method as well as an apparatus for removing volatile components, such as chloride, alkali and sulphur, from a cement manufacturing plant, which plant comprises a preheater (1) for preheating cement raw materials, a kiln (5) for burning cement clinker, and a transition zone (3) between the preheater (1) and the kiln (5). The method and apparatus is peculiar in that a condensation body (9) having a temperature which is lower than the condensation temperature of the volatile components is introduced into the exhaust gases at a location where the temperature of the exhaust gases exceeds the mentioned condensation temperature so that volatile components when brought into contact with the condensation body are cooled to a level below their condensation temperature and are thereby condensed and deposited on the condensation body (9), and in that the condensation body (9) is subsequently taken out from the exhaust gases and cleaned of deposited condensation products.
