Abstract:
1. A particle separator for use in conjunction with a grinding mill, for sorting ground particles according to sizes thereof, comprising: a driving shaft; two upper and lower support rings, which are mutally aligned and of circular shapes, being fixedly connected to a shaft sleeve at a center thereof, said shaft sleeve being mounted on said driving shaft; and a plurality of spokes, extending inward from said support rings, wherein, by connecting said plurality of spokes and said shaft sleeve, a plurality of openings is left between inner sides of said support rings and said spokes, allowing air to pass through; characterized by said two support rings having a plurality of mounting holes close to peripheral edges thereof; and a plurality of blades, each mounted on peripheries of said two support rings, having on one side close to said support rings two aligned rotational axes and two holding rods, which are oriented perpendicular to said two support rings, said two holding rods being inserted into said plurality of mounting holes, allowing said plurality of blades to sway when mounted on the support rings; and said mounting holes of said support rings being arranged in a quantity that is a divisible number, so that, when said blades are installed, any divisor of said quantity of mounting holes serves as a guide for a number of mounting holes between mounted blades; wherein particles ground in said grinding mill pass, carried by an air flow, through said blades and an air flow vortex, brought about by said blades causes relatively large and heavy particles to undergo a centrifugal force and to be pulled outward, so that an object of separating particles is achieved.
