Embodiment 1

[0029] refer to Figure 1-5 , a soft ferrite raw material grinding and crushing device, comprising a feeding hopper 1, a grinding box 2 and a fine grinding box 3 below the grinding box 2, the upper end of the feeding hopper 1 is provided with a feeding port 4, and the feeding hopper 1 Two first grinding rollers 5 are arranged on the top, and the first grinding rollers 5 are rotationally connected with the side wall of the feed hopper 1 through the first roller shaft 32 arranged at the center, and one end of the first roller shaft 32 runs through the feed hopper 1 is connected to the output shaft of the external first motor 9, and two second grinding rollers 6 are arranged below the first grinding roller 5, and the second grinding rollers 6 are rotatably connected to the side wall of the feeding hopper 1 through the second roller shaft 7 , and the second roller shaft 7 passes through the side wall of the feed hopper 1 and is connected to the output shaft of the fourth motor 28,...

Embodiment 2

[0038] Such as Figure 1-5 As shown, this embodiment is basically the same as Embodiment 1. Preferably, the first grinding roller 5 is provided with grinding teeth 33, and the two first grinding rollers 5 are meshed through the grinding teeth 33, and the feeding hopper 1 The inner side wall is slidingly connected with the grinding teeth 33; the upper end surface of the grinding plate 8 is an arc-shaped concave surface slidingly connected with the second grinding roller 6, and the connection between the grinding plate 8 and the first communication port 10 is curved and inclined. The first grinding roller 5 effectively pulverizes the raw material with large particle size, and facilitates the subsequent continuous grinding and facilitates the lip grinding of the pulverized large particle size raw material by the second grinding roller 6, thereby improving the overall grinding efficiency.

Embodiment 3

[0040] Such as Figure 1-5 As shown, this embodiment is basically the same as Embodiment 1-2. Preferably, the upper half of the grinding block 13 is set in a smooth arc shape, and a plurality of grinding blocks are set on the side where the lower half is slidably connected with the grinding side plate 14. Bump 35. Effectively improve the grinding efficiency of the grinding block 13 for grinding materials, and prevent materials from accumulating on the grinding block 13 at the same time.

[0041] In order to facilitate the material to fall into the fine grinding box 3, and to facilitate the fine grinding of the material by the pressure plate 36 and the screening plate 39, preferably, the two sides of the bottom of the grinding box 2 are provided with symmetrical second communication ports 18 and fine grinding The box 3 is connected, and the bottom of the grinding box 2 is located around the pillar 16 and is provided with an inclined block 17, and the inclination direction is t...

Abstract

The invention discloses a soft ferrite raw material grinding and crushing device, which relates to the technical field of soft ferrite processing. It includes a feeding hopper, a grinding box and a fine grinding box. Two first grinding rollers are arranged on the top of the feeding hopper, two second grinding rollers are arranged under the first grinding roller, and a grinding plate is arranged under the second grinding roller. , there is a pillar at the center of the bottom of the grinding box, the pillar is surrounded by a circle of grinding side plates, the top of the grinding box is rotatably connected to the first rotating shaft, the lower end of the first rotating shaft is fixed with a grinding block, the upper end of the fine grinding box is equipped with a cylinder, and the lower end of the cylinder is connected to a telescopic rod , a pressure plate is fixed at the bottom of the telescopic rod, and the pressure plate is located directly above the screening plate and has the same size. The invention overcomes the deficiencies of the prior art, has reasonable design, is convenient to use, can effectively continuously grind and pulverize ferrite raw materials, improves the effect and efficiency of grinding and pulverization, promotes the production and processing of ferrite, and prevents waste of raw materials.

Description

technical field [0001] The invention relates to the technical field of soft ferrite processing, in particular to a soft ferrite raw material grinding and pulverizing device. Background technique [0002] Soft ferrite is based on Fe 2 o 3 The ferrimagnetic oxide as the main component is produced by powder metallurgy, and it is mainly a "functional ceramic material" that is sintered by mixing iron oxide and other metal oxides. It has better magnetic permeability. Compared with ordinary metals, it has the advantages of weaker coercive force and smaller residual magnetism after the external current is removed. [0003] Generally, the preparation of soft ferrite mainly includes the steps of material particle grinding, mixing, sintering, etc. During the preparation process of ferrite, the precision of aging grinding is different according to the different requirements of the ferrite type and raw materials, while the traditional The ferrite grinding method is mostly carried out ...
