finely dividing by a fluted disc type pulverizer: the feeding port of the fluted disc crusher is connected with a star-shaped discharge valve and a charging bucket thereof through sealed flexible connection, the fluted disc crusher is fed by controlling the star-shaped discharge valve, the discharge size of the fluted disc crusher is controlled through the size of an internal screen, the discharge port of the fluted disc crusher is designed to meet the requirement of vacuum feeding and has the air supplementing function, the material at the discharge port is conveyed into a designated charging bucket through a vacuum feeding mechanism, and the quantity of other equipment of the charging bucket is designed according to the yield; selecting the specification of a screen and the number of layers of the screen according to the requirements of a vibrating screen root, and conveying the materials meeting the requirements after passing through the vibrating screen to a preset material feeding structure;
secondary screening: the charging bucket for discharging and conveying the fluted disc crusher is characterized in that a star-shaped discharge valve and a disc-type vibrating screen are connected through sealed flexible connection, the disc-type vibrating screen is fed by controlling the star-shaped discharge valve, the specification and the number of layers of screen meshes are selected according to the requirements of the foundation of the vibrating screen, the materials meeting the requirements after passing through the vibrating screen are sent to a preset finished product charging bucket through a vacuum feeding structure, and the screened coarse materials pass through a vacuum feeding series system, return to a raw material tank and are subjected to secondary crushing; unqualified fine materials are collected through a material receiving hopper below the screen body;
s4, packaging of finished products: after multi-path screening by a disc type vibrating screen, respectively conveying finished products to a specified finished product tank through a vacuum feeding mechanism, and improving the purity of powder in the tank through an iron removal device in the conveying process; the star-shaped discharge valve that each material jar of automatic packaging finished product packagine machine flexible coupling matches, packagine machine can freely set for packing weight as required, and the sack dust collector is connected to the easy dust position that produces of whole packaging process, prevents that the dust from leaking.
