Abstract

The invention discloses a continuous through dry sand mill for ferrite. The continuous through dry sand mill comprises a support, a material barrel, an electric control cabinet, a motor, a feeding hole, a discharging hole, an exhaust port and a stirring part, wherein the material barrel is cylindrical; the material barrel, the electric control cabinet and the motor are all arranged on the support; the motor is located above the material barrel; the feeding hole and the exhaust port are both formed in the upper part of the material barrel; the discharging hole is located in the bottom of the material barrel; the stirring part is located in the material barrel; and the stirring part is connected with an output end of the motor. The continuous through dry sand mill provided by the invention overcomes the defects of incomplete reaction and generation of other phases caused by non-uniform material mixing and loose particle contact of a single dry mixing process commonly used in the industry at present, and ensures that various components are uniformly mixed, and particles are refined and are in close contact, so that solid-phase reaction in the sintering process is promoted, and the sintered ferrite permanent magnet material with relatively high performance can be obtained.

Description

technical field [0001] The invention relates to the field of ferrite preparation, in particular to a continuous passing dry sand mill for ferrite. Background technique [0002] At present, the manufacturing methods of sintered ferrite permanent magnet materials can be divided into wet process manufacturing method and dry process manufacturing method according to the mixing method. The wet process manufacturing method is to make various raw materials into slurry, mix and calcinate through wet ball milling or sand milling, so as to ensure that various raw materials are mixed evenly and can obtain high-performance sintered strontium ferrite permanent magnet materials, but This process has the disadvantage of high water content in the slurry resulting in high energy consumption. The dry process manufacturing method refers to the use of a dry strong mixer to mix various raw materials in a certain proportion, pelletize and calcine. This process results in poor mixing uniformity a...
