摘要： A process for separating a fusion mix sample comprising a slag material and a collector material using a separator. The separator comprising a plurality of impact members configured to rotate. The process comprising the steps of providing a solid fusion mix sample and loading the solid sample into the separator. Dislodging the slag material from the solid fusion mix sample by rotating the impact members and contacting the rotating impact members and the solid fusion mix sample. Separating into a first fraction substantially comprising the collector material and a second fraction substantially comprising slag material.

摘要： A fluidized bed separator (1) includes a feed section (4) between an upper separation chamber (19) and a main separation chamber (6). The feed section (4) has one or more feed pipes (11) extending horizontally and transversely with respect to a body wall (10) of the fluidized bed separator (1). The one or more feed pipes (11) are positioned completely and entirely underneath the inclined plates (17). An external oversize protection apparatus (3) which is separate from and external to the body wall (10) may be operatively coupled to the one or more feed pipes (11). One or more lamella cartridges (49) may be provided within channels (18) of the upper separation chamber (19), and one or more breakaway plates (54, 55) may be inserted within channels (18) to prevent sanding and facilitate insertion and extraction of the lamella cartridges (49).

摘要： A conveyor for pulverized material comprises in combination a conduit, a screw rotatably mounted within the conduit having a material inlet end and material discharge end, means for rotating the screw, means for supplying material to the screw at the material inlet end, whereby the material will be compacted as it is advanced by the screw to the material discharge end, and means for admitting a gas under pressure to the compacted material at the material discharge end to render it fluent. In a portion of the screw a material seal is formed by the compacted material being advanced by the screw, wherein there are material pockets formed between adjacent screw flights, wherein the pocket size volume is at its maximum nearest the material inlet end and at its minimum nearest the material outlet end, with at least twice as many pockets of minimum size as of maximum size.

摘要： A new and improved hydrocyclone roping and wear management system and method for its use are provided. The system includes one or more wireless electronic roping sensors and/or one or more wireless electronic wear sensors disposed in communication with one or more hydrocyclones, along with a wireless electronic controller. The system is capable of wirelessly detecting roping and/or wear conditions within one or more hydrocyclone separators during their operation, communicating electronic data corresponding to the roping and/or wear conditions to an associated hydrocyclone control system, and causing adjustments in controlling operational parameters for the hydrocyclones. The associated method includes steps for wirelessly acquiring roping and/or wear condition data using the wireless electronic controller and delivering the data to the hydrocyclone control system. The system and method provide for improved roping detection and wear maintenance scheduling, and improved adjustment of undesirable roping and wear conditions.
