At the same time, the eddy current effect inside the machine makes the material circulate continuously in the pulverizing chamber until it reaches the required particle size. In pharmaceutical production, the eddy current mill is mainly used for ultrafine pulverization of medicinal materials.

[0021] The spiral feeding mechanism squeezes the raw materials in the hopper 3 to the lower end of the feeding barrel 2, and the one-way extrusion valve 4 is opened under pressure to continuously transport the raw materials to the vortex grinder 1. The airflow of the vortex grinder 1 cannot flow back into the feeding barrel 2 to interfere with the feeding. The air holes on the outer wall of the vortex grinder 1 keep the internal pressure of the vortex grinder 1 balanced, and the pressure increase caused by the feeding will not affect the vortex.

[0022] The spiral feeding mechanism comprises an input shaft 5, the input shaft 5 is connected to a spiral blade 6, and the spiral blade 6 is located in a horizontally arranged feeding barrel 2;

[0023] The horizontally arranged feed barrel 2 can effectively reduce the raw material weight pressure on the one-way extrusion valve 4 and extend the service life of the one-way extrusion valve 4.

[0024] The eddy current pulverizer 1 comprises a pulverizing shell 11, the upper part of which is connected to the feed barrel 2, a grate plate 12 is connected inside the pulverizing shell 11, the grate plate 12 is connected to the upper surface of a bracket 13, the bracket 13 is provided with a hole connected to the bottom of the pulverizing shell 11, the pulverizing shell 11 is connected to a collecting chamber 14 through the hole, a pulverizing shaft 15 is rotatably connected to the bracket 13, a turntable 16 is connected to the lower part of the pulverizing shaft 15, the turntable 16 is in contact with the inner wall of the grate plate 12, a vortex fan blade 17 is connected to the turntable 16, and a pulverizing knife 18 is connected to the upper part of the pulverizing shaft 15;

[0025] The power drives the crushing shaft 15 to rotate, the crushing shaft 15 drives the turntable 16 to rotate, the turntable 16 drives the vortex blades 17 to rotate, the vortex blades 17 drive the deposited materials at the bottom to rise along the inclined surface and disturb the airflow, so that the materials always keep floating and rotating without sedimentation.

When the raw material is extruded, the raw material pushes the blocking plate 41 and the rotating shaft 42 to rotate in the spring lower bracket 45. The lower ear of the blocking plate 41 drives the spring upper bracket 44 to press down and drive the torsion spring 43 to be further compressed to complete the discharge.
