Abstract
The utility model discloses a material feeding device of a dry type ball grinder. The material feeding device has the advantages of simple structure, economical property, practicability and the like. The material feeding device comprises a hopper body, wherein an air inlet is formed in one end of the hopper body; a material inlet is formed at the upper part of the hopper body; the lower end of the material inlet is welded with a material curtain; the material curtain comprises two connection plates and three material curtain steel plates which are in a ladder distribution; and the material curtain steel plates are welded to the connection plates. Materials enter a barrel body of the ball grinder through the material inlet and fall onto the material curtain; and then, air entering from the air inlet blows the materials into the barrel body to be ground; the materials are not in direct contact with the hopper body, so that the hopper body cannot be abraded; a lining steel plate is not arranged at the bottom of the hopper body; and the materials are uniformly fed and can be completely ground.
