摘要： The present invention relates to a device for separating blasting dust from blasting agent, whereby separation occurs in a separating space (16) from which the blasting dust (15) is sucked into a dust collecting device (19) while the blasting agent (13) is fed to a recirculating device (12) for recycling thereof, and whereby the blasting dust (15) is sucked into the dust collecting device (19) by generating a negative pressure therein by means of a negative pressure-generating device. In order to eliminate the need for bulky fan devices for generating negative pressures in the dust collecting device, the negative pressure-generating device includes an air guide means (32) which is connected to a compressor (9) and feeds air from said compressor in a direction from a blasting dust inlet (30) towards a collecting container (21) for blasting dust (15).

摘要： An air classifier having an upright housing open at both ends in which a pipe section is concentrically located to define a first annular passage closed at its upper end. A feed conduit attached to a pneumatic delivery system is concentrically located within the pipe section defining a second annular passage open at both ends. A cover is mounted over the upper end of the housing defining a dispersing chamber for bulk material. The dispersed material falls through the second passage, beyond the lower end of the pipe into an annular chamber where the components are separated by an air stream moving upwardly. The heavier particles falls and the lighter particle travel with the upward air.

摘要： A particle separator physically separates a mixture of small and large particles and metal particles which are suspended in a stream of air into discrete groups of small particles, large particles and metal particles. The particle separator includes a chamber having a bottom and including an inverted truncated cone. The cone includes an upper skirt which forms a seal with the inner wall of the chamber and an aperture in the lower end. The cone divides the chamber into upper and lower compartments. An inlet duct extends through the wall of the chamber into the upper compartment of the chamber. A filter plate is positioned within the lower compartment of the chamber and includes a first side surface which forms a seal with the inner wall of the chamber and a second side surface which forms a seal with the wall of the cone. The structure of the filter defines an intermediate compartment in the upper portion of the lower compartment. An outlet duct extends throught the wall of the chamber into the intermediate compartment. A blower is coupled to the separator and produces a flow of air from the inlet duct through the upper compartment and through the aperture in the cone into the lower compartment, through the filter into the intermediate compartment and out through the inlet duct. A valve in the bottom of the chamber removes large particles from the chamber.

摘要： A method and apparatus is provided for separating heavier particulate material from a mixture of light particulate material, heavy particulate material and gas. The apparatus includes a vessel having an outlet at a lower portion thereof wherein particulate material flows toward the outlet and is contacted by countercurrent flow of gas for uplifting of lighter particles of particulate material. Heavy particulate material and some light particulate material is then collected in a chamber of a valve wherein sequential injections of gas in a lower portion of the chamber further separates light particulate material from the heavy particulate material with the remaining particulate material in the chamber being discharged by sequential operation of the valve.

摘要： In a vertical classifier, a high efficiency of separation is achieved by recirculating a portion of the main fluid stream within the classifier so as to create a horizontal vortex whereby larger particles are prevented from passing with the fine fraction; incoming fluid serves to carry fines from such recirculated portion of the fluid stream.
