ABSTRACT:
A milling method for pulverizing agricultural products, minerals, etc. comprises the steps of whirling a grain material within a pulverizing chamber; and pulverizing the material by utilizing the friction due to a difference in moving speed between material particles which is generated as the material is whirled. A milling device comprises: a body frame; first and second rotary blades arranged opposite to each other within the body frame and defining, together with the inner walls of the body frame, a pulverizing chamber; a material feeding inlet formed on the body frame on the side of the first rotary blade and communicating with the pulverizing chamber; and a collection outlet provided axially in alignment with the second rotary blade and communicating with the pulverizing chamber. The collection outlet communicates with an associated suction device.
