Embodiment

The utility model is further described with embodiment below in conjunction with the accompanying drawings.

Refer to shown in Fig. 1 to Fig. 4, a kind of high-efficiency turbine sand mill, including frame 10 and be arranged in frame 10 Lapping device 20, wherein, the lapping device 20 includes grinding drum 21, main shaft 22 and the mechanical seal group being installed on main shaft 22 Part 23, the side of grinding drum 21 has a charging aperture 211, the external feed pipe of the charging aperture 211（It is not shown）, abrasive media and Material enters in grinding drum 21 from the charging aperture 211.The one end of main shaft 22 is provided with a drive device 24, and by drive device 24 Main shaft 22 is driven to rotate, specific dynamical system can use prior art, such as motor-driven belt wheel drive mechanism adds give herein Repeat.One turbine rotor 25 is installed in the other end of the main shaft 22, between turbine rotor 25 and mechanical sealing assembly 23 Main shaft 22 on be set with a plurality of spaced blades 26, the turbine rotor 25 is located in grinding drum 21 with blade 26, The turbine rotor 25 is integrated barrel-shaped structure, and its one end is opening-like, and the other end has a connection member 251, passes through the company Relay part 251 is connected with main shaft 22, and a plurality of through holes with gradient are provided with being spaced apart on the barrel 252 of turbine rotor 25 253, the through hole 253 can shuttle for abrasive media and material, it is to avoid grinding dead angle, lift grinding effect, to make more preferably Ground realizes that material shuttles, and wherein through hole 253 is uniformly distributed on barrel 252, and the turbine rotor 25 has an accommodating cavity 254, the interior material installed filtering net cylinder 30, required particle diameter is filtered out by filtering net cylinder 30 of the accommodating cavity 254, and by going out Material mouth 212 is exported, the external discharge nozzle of the discharging opening 212（It is not shown）.
