The point of the present invention is to reduce the size of the crushing portion structurally as much as possible and pay attention to the air flow generated by the high speed rotation of the roller. To pass the fine powder through. Moreover, since the material to be crushed is not powder that has been forcibly crushed by a roller and a pot and rushed out, but is once put in an air current, the adhesion of the powder on the inner wall of the crushing chamber is very small and almost all of the fine powder is removed. Can be taken out.

In order to ensure smooth rotation of the crushing roller and a reasonable crushing operation, the inner diameter of the center hole of the crushing roller is usually appropriately larger than the outer diameter of the roller rotating pin, and a clearance is provided between the two. It is desirable to form. It is recommended that a cone-shaped convex portion is formed at the center of the inner bottom surface of the crushing pot so as to promote the generation of an updraft in the crushing pot. In order to prevent clogging and maintain the passage property of only fine powder having a predetermined particle size, it is recommended to use a double screen in which two types of screens having different meshes are superposed. In addition, at the same time as releasing air from the pulverizing pot part, in order to prevent scattering of the sample powder, an openable and closable filter comprising a precision filter that allows only air to pass through the outlet of the powder collecting container and prevents the sample powder from passing therethrough. It is desirable to provide a shutter.

At this time, since the crushing rollers 2 and 2 rotate at a high speed, a spiral air current is generated inside the crushing pot, and the fine powder of a sample (mine, ore, etc.) crushed by the crushing pot and the crushing roller. Riding on the spirally generated airflow, passes through the double screen 4, descends between the cylindrical portion 51 of the housing 5, and is stored in the sample powder collecting container 17 by the sample removing chute 7. Further, in order to promote the effect of crushing and collecting the remaining sample, a cone-shaped convex portion 1a is provided at the center of the crushing pot 1 to prevent the fine powder from gathering at the center and to generate an upward airflow from the bottom of the crushing pot. So that all of the fine powder can be taken out of the grinding pot.
