The present invention relates to a pulverizer powder separating apparatus which prevents the powder pulverized using the rotating brush from sticking to the inner wall surface (wall surface) of the grinding chamber and separates the powder stuck to the inner wall surface of the grinding chamber. will be.

In general, grains such as rice, barley, soybeans, wheat, etc., or medicinal herbs (hereinafter referred to as 'pulverized matter'), such as medicinal herbs or charcoal, are pulverized into powders of a predetermined particle size for the sake of use or necessity. .

A grinder is widely used as a means for pulverizing the pulverized products, and most of the pulverizers are pulverized by using a high-speed rotating body to generate wind pressure (strong air flow or movement) with centrifugal force.

Therefore, as a means for separating the powder from the wind pressure generated during the crushing process, the powder is collected by installing a bag-type bag that is bundled with a rubber band at the outlet of the crusher. Then, when the pulverized powder is filled in the bag-shaped bag, the grinding machine is stopped, and the bundled rubber band is released to separate and collect the powder filled in the bag. The crusher is operated by operating the grinder with the bag sealed.

In this case, it is not only cumbersome to loosen and tie the rubber band to the end of the bag, and to stop the grinder to collect the pulverized powder. There is a concern that this is unsanitary, there is no continuity of the grinding operation, such as low productivity.

On the other hand, in order to solve the problem of the pulverizer by separating the powder and the wind pressure to continuously collect the powder is easy to separate the collection work of the powder as well as hygienic and continuous crushing operation is possible to improve the productivity from the 'crusher Applicant and inventor filed a utility model registration (No. 20-2006-0014279) by the applicant and inventor of the separate collection device (hereinafter referred to as 'powder collection device') of pulverized powder. It was registered as Utility Model Registration No. 20-424346.
