摘要： Screen for separating solid residues, and in particular for separating sheet or expanded material, such as bags or parts of bags made of plastic, polystyrene, spongy material or another light material, which comprises a separation station (10) interposed between the inlet port (P1) and the outlet port (P2) of the screen above its screening surface (P) and preferably after the powders and the lightest portions have already been separated. The station (10) comprises a hood (11) delimiting a suction chamber (13), and insufflation means (15) for orienting at least one lifting air flow (16) in the suction chamber (13) at the screening surface (P). The lifting air flow (16) is oriented for forming a vortex (17) confined in said suction chamber (13) and with rotation axis (Z) orthogonal to the screening surface (P) capable of lifting the sheet material and delivering it to suction means (18) associated with the hood (11).

摘要： Processing byproduct material from a direct reduction process of iron ore to reclaim iron and other materials from the byproduct. The systems and methods employ gravity separation tables to separate the iron from other byproduct material constituents. The byproduct material constituents may be size reduced, processed to remove dust, and sized prior to processing by the gravity separation.

摘要： An open configuration is provided for the housing of a particulate material dedusting apparatus through which particulate material passes to be cleaned by air passing through wash decks to separate dirt and debris from the particulate material for discharge from the housing. The front wall and side access doors of the housing are configured to be openable for full access to the front and rear chambers. The primary wash deck is detachably mounted within the housing for removal for cleaning purposes. The generally horizontal floors of the housing are formed with a slope to allow water to drain from the housing. The open configuration of the deduster housing facilitates cleaning, draining and drying of the housing to expedite changeover from one material to another. Furthermore, the open configuration allows access for improved welding to eliminate cracks and openings in joints which accumulate dirt and debris during operation.

摘要： Fine particles which electrostatically adhere to synthetic resin pellets are separated from the pellets by bringing the pellets/fine particles mixture into contact with an ionized gas. The ionized gas eliminates the electrostatic adhesion between the synthetic resin pellets and the fine particles. The resulting fine particles may thereafter be readily separated from the pellets and the freed fine particles may be withdrawn in a gas stream. Removal of the fine particles to less than 40 ppm is possible. Apparatus for carrying out the method is also described as is a system for stocking synthetic resin pellets using the described apparatus.

摘要： A semolina cleaning apparatus allows basic operations as in the prior art with complete visual surveillance of operation, but with an outwardly closed product guidance. In this way, entry and exit of dust is completely prevented during normal operation as well as when removing samples. Accordingly, it is possible to operate an individual apparatus as well as an entire group of semolina cleaning apparatuses with circulating air. The air intake can be effected from above.

摘要： The subject deduster employs gravity to feed the dust and impurity laden particulate material through a linear kinetic energy cell, which cell generates an electric field to neutralize the static electric charges causing the dust to adhere to the particulate material. With the static electric charge neutralized,the dust can be separated by an air flow substantially transverse to the particle flow. The cleaning can be accomplished by pressurized air or a vacuum. The deduster can include means to collect the dust after it has been separated for the particulate material.

摘要： Disclosed is an apparatus and method for separating a pellet-like product from fines mixed therewith. The apparatus includes a housing having a fines outlet and a product outlet disposed at a lower portion of the housing. An inlet conduit extends into the housing and terminates in a nozzle. The inlet conduit receives quantities of the product and fines entrained in a propellant fluid such as pressurized air. An imperforate baffle having an impact surface is disposed within the housing so that the impact surface faces the nozzle to intercept the product issuing from the nozzle. Apparatus is provided for generating an electric charge neutralizing magnetic field to envelop the entrained product and fines before the product impinges upon the impact surface of the baffle.
