Wear is relatively large and requires regular maintenance. Also, the pestle 52 is loose, and the lower end of the pestle 52 and the mortar 5
1 and the grinding ability is reduced. Since the stroke of the punch 52 is constant, it is difficult to change the impact force depending on the type of the raw material, and the use is limited. Since the punch 52 is generally long and has a motor and the like for driving, the punch 52 is large and it is difficult to take measures against dust collection and noise. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a compact electromagnetically driven stamp mill that can adjust the impact force applied to a raw material with a simple structure and that has little wear and the like.

Then, the lower mortar 12 is placed in the upright state, the door 39 is opened, a material such as iron particles is put in, the door 39 is closed, and the operation is started in this state. When the operation of the electromagnetically driven stamp mill 10 is started, the punch 13 is slightly raised by operating the electromagnet 15, and the locked state of the punch 13 by the advance / retreat rod 36 or the receiving plate 38 is released.
The electromagnet 15 is de-energized, and the punch 13 is dropped to give a shock to the raw material. Thereafter, the electromagnet 15 is energized in a pulsed manner, so that the vertical movement of the punch 13 is repeated. The adjustment of the impact force of the punch 13 is performed by adjusting the voltage of the electromagnet 15. Since dust is generated by this operation, the motor 2
8 is rotated to capture the dust generated. In addition, shocks and vibrations are mitigated by the casing frame 23, and the mounting table 11 is heavy, so that vibration and noise are also reduced. Since the nonmagnetic portion 22 is provided in the middle of the punch 13 (intermediate position), the excitation of the punch 13 by the excitation of the electromagnet 15 is stopped halfway, and the punch 21 provided at the lower end of the punch 13 is excited. Since the iron particles are not
It does not adhere to After the above operation, the punch 13 is fixed at the upper position, and the product is taken out of the mortar 12. In this case, the mortar 12 can be tilted by 90 degrees.

It is possible to operate a plurality of electromagnetically driven stamp mills in parallel. In this case, by controlling the energization of the electromagnets of the respective electromagnetically driven stamp mills so as not to overlap, power saving can be achieved and noise and vibration are reduced. Further, in the above-described embodiment, the mounting table filled with heavy concrete is used. However, it is also possible to fix the main body of the electromagnetically driven stamp mill 10 by separately providing a foundation.

することによって、乳鉢の取扱いが容易となる。In the electromagnetically driven stamp mill according to claims 1 to 4, since the electromagnet is used for lifting and lowering the punch, the impact force of the punch can be freely adjusted by changing the applied voltage, so that it can be adjusted to the raw material. The impact force can be adjusted. In addition, since the core core at the top of the punch is guided by the cylindrical sleeve, the play in the horizontal direction of the punch is also reduced, and the number of supports that prevent the punch from swinging in the horizontal direction can be reduced. , Maintenance is reduced. In particular, in the electromagnetically driven stamp mill according to claim 2, since the yoke core for capturing the leakage magnetic flux is provided around the electromagnet, the electromagnet is effectively used, and the electromagnet is small and has a large force. Further, generation of leakage magnetic flux can be prevented as much as possible. In the electromagnetically driven stamp mill according to the third aspect, since a non-magnetic material is used in the intermediate portion of the rod-shaped punch, magnetic force is not transmitted to the lower portion of the punch, and as a result, even if the raw material is a magnetic material And adverse effects such as sticking to a punch can be reduced. And
In the electromagnetically driven stamp mill according to the fourth aspect, since the entire apparatus is fixed on a mounting table made of a heavy material, vibration and noise are reduced. Further, by setting the height of the mounting table to the working height, handling of the mortar becomes easy.
