Description

  The present invention relates to a pulverizer for pulverizing an object to be pulverized such as agricultural products, foods, minerals, and pharmaceuticals.

  Conventionally, there are a wet pulverizer and a dry pulverizer as pulverizers for finely pulverizing (pulverizing) an object to be pulverized. As a wet pulverizer, there is known an apparatus capable of emulsifying a material to be pulverized and refining particles by causing the materials to be pulverized to collide with each other.

  As a dry pulverizer, the object to be crushed is placed on the airflow generated by rotating two opposed rotating blades in the casing, and the object to be pulverized is repeatedly made by repeatedly colliding with the rotating blades of the object to be crushed. A pulverizer that pulverizes and sucks and collects the pulverized material with a suction device connected to a discharge port is known (for example, see Patent Document 1).

As other dry pulverizers, there is known an apparatus that is based on the ratio of the product of the rotational surface speed and the total surface area on the front side in the rotational direction of the inlet-side rotor and the discharge-side rotor (for example, , See Patent Document 1).
Further, a pulverizer that adjusts the airflow in the casing by changing the interval between the rotary blade and the casing is known (for example, see Patent Document 2).
