Efficient blender mixer for neodymium iron boron magnet production

The invention provides an efficient blender mixer for neodymium iron boron magnet production. The efficient blender mixer comprises a base, a rotary box, support shafts, bearing bushes, protective covers, an opening, sliding grooves, material mixing rods, an nitrogen inlet, a nitrogen outlet, an upper floating hole, a lower floating hole, an air inlet pipe, an air purifier and an air pump device;support shafts are symmetrically arranged at the middle parts of two sides of the rotary box, and the rotary box is erected at an upper part of the base; the upper part of a support shaft is connectedwith the bearing bush for limiting the radial location of each support shaft, the end part of each support shaft is connected with a protective cover for limiting the axial location of each support shaft. Through the arrangement of the sliding grooves and the material mixing rods, when the rotary box begins starting and rotating, the material mixing rods in various sliding grooves can alternatelyfall and slide under the action of gravity, thereby playing material mixing effect for the iron boron magnet powder of the cavity; the mixing uniformity is improved, the mixing quality and efficiencyare improved, the structure is novel, the mounting is convenient, and the operation is convenient.
