Introduction: FDV ultrafine grinder is the use of crushing the high-speed rotation of the blade and the air flow cyclone separation in the form of dry material to achieve ultra-fine grinding equipment. It consists of feeding mouth, aggregate tank, crushing chamber, high-speed motor and other components. Material from the feed port into the crushing chamber, the high-speed rotation of the blade impact crushing, high-speed rotation of the blade also caused the flow of air flow, so that after the crushed material to the crushing tank, the air flow through the filter bag to complete the crushing. FDV ultrafine grinder can be widely used in traditional Chinese medicine, western medicine, pesticides, biotechnology, cosmetics, food, feed, chemicals, ceramics and other industries dry materials, ultra-fine grinding needs. Features: (D98); hard and brittle material crushing fineness of up to 12-44μm (D98); can fully meet the needs of users of ultra-fine grinding (1) fineness, plant fiber crushing fineness of up to 40-100μm (D98) The (2) design clever, the mechanical crushing, airflow crush the advantages of integration in one, the special structure of the knife, a great expansion of the crushing range, to adapt to the needs of users of a variety of materials crushing. (3) small size, light weight, compared with other types of crusher at this level, greatly reducing the volume reduced weight, can be placed on the use of the table, the laboratory is particularly convenient for users. (4) handling is good, the machine for the continuous feeding type, connected to the power can be, one person can use. (5) safety performance, easy to clean, without sieving, due to the use of fully enclosed structure, the operator is not in direct contact with the crushing chamber.
