摘要： A system for suppressing and inhibiting fires in coal pulverizer mills can include a fire suppression solution storage tank, a flow control cabinet, an equipment control/pumping enclosure, an air distribution system, and injection piping and nozzles installed at various positions in one or more pulverizer mills. A first set of nozzle assemblies in communication with the fire suppression solution can be positioned in the mill to disperse the suppression solution within the classifier zone of the mill. A second set of nozzle assemblies in communication with the suppression solution can be positioned within the mill to disperse the suppression solution within the grinding zone. A third set of nozzle assemblies can be positioned within the primary air duct of the mill.

摘要： An improved deflector structure for an updraft classifier mill for coal and ore is described. The improved deflector structure has an impingement surface which is characterized by a pattern of surface irregularities, either raised geometric figures or recesses of varying sizes and shapes to create turbulence in the air emerging from a rotating vane structure and impinging the deflector as it travels upwardly through the mill housing.

摘要： A roller mill for grinding particulate material such as cement raw materials, cement clinker and similar materials comprises a mill housing surrounding a substantially horizontal grinding table, a number of rollers each rotating about a roller shaft and configured for interactive operation with the grinding table and at least one mechanism or device for introducing gases into the mill housing. The at least one mechanism or device for introducing gases into the mill housing comprises an annular duct having openings in a wall facing the grinding table and being located around the outer circumference of the grinding table. As a consequence hereof, a significant reduction of the pressure loss in a roller mill and thus a significant reduction of energy consumption will be ensured.

摘要： An annular impactor structure for use in crusher/classifiers of the updraft type. An annular structure comprising a plurality of radially inwardly projecting, essentially vertical impactor plates of high-hardness material is located immediately above a vane structure such that entrained particulate matter from a milling bowl impacts one or both of the impactor plate surfaces. The impactor plates as well as the backer structures between the impactor plates are covered with coin-shaped protrusions. The impactor plate structure can be used in combination with a single or double course vane structure.

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.

摘要： A roller mill for grinding particulate material such as cement raw materials, cement clinker and the like includes a grinding table and a set of rollers rotatable about a vertical shaft. The set of rollers include a number of rollers rotating about separate roller shafts, which are connected to the vertical shaft. A nozzle ring for directing gases into the roller mill is also included. The nozzle ring encloses the grinding table. Means for regulating the gas flow through the nozzle ring is also provided. At least some of the regulation means are arranged to rotate together with the rollers. Preferably, the position of at least some of the regulation means for regulating gas flow through the nozzle ring relative to the rollers may remain the same so that the gases introduced into the mill via the nozzle ring may exhibit the same flow pattern in relation to the rollers.

摘要： A solids pulverizing mill for producing fine particles such as coal dust, which includes a housing having a centrally located coal feed chute and enclosing an annular-shaped air port ring containing multiple nozzles located around a rotatable grinding table. Multiple grinding rollers press down and rotate upon the coal on the rotatable grinding table so as to pulverize the coal, which is then entrained by multiple intersecting and strongly interacting air jet streams upwardly from the grinding table through a classifier section to an exit conduit. The air port nozzle ring is fitted with multiple angled flow passages from which adjacent air jet streams intersect and interact strongly with the adjacent streams to product intense turbulence, which prevents undesirable acoustic vibration of the upflowing air/coal material within the mill housing. The centerlines of adjacent air jet nozzles intersect at an included angle of at least 20.degree. and not exceeding 90.degree., each nozzle has cross-sectional area of 10-50 in..sup.2, and provides nozzle exit air flow velocities of 140-250 ft/sec so as to prevent undesired acoustic resonance vibrations within the pulverizer mill.
