Embodiment

[0035] Please refer to figure 1 , figure 1 A schematic diagram of the structure of the stirred mill 100 is shown. This embodiment provides a stirring mill 100, which mainly utilizes the stirring motion of the grinding medium to produce impact, shearing, and grinding effects, so as to achieve the purpose of crushing materials.

[0036] The stirred mill 100 mainly includes a screw lift shaft 110 , a stirring assembly 150 and a barrel body 190 . Both the stirring assembly 150 and the helical lifting shaft 110 are located in the barrel main body 190 . Such as figure 1 As shown, both the screw lifting shaft 110 and the stirring assembly 150 are arranged to be partly located inside the cylinder main body 190 and partially located outside the cylinder main body 190 . The part located outside the cylinder main body 190 is convenient for transmission connection with driving equipment such as a motor, so that the screw lifting shaft 110 and the stirring assembly 150 can rotate.

Abstract

The invention provides a seven-axis stirring grinder, and relates to the field of grinding equipment. The seven-axis stirring grinder comprises a spiral lifting shaft, a stirring assembly and a main cylinder body, and both the stirring assembly and the spiral lifting shaft are located in the main cylinder body. The spiral lifting shaft comprises a first rotating shaft and blades spirally arrangedaround the first rotating shaft. The first rotating shaft drives the blades to rotate in the rotation process, materials at the bottom can rise gradually along the spiral blades, the materials constantly move from bottom to up along the spiral blades, the materials at the bottom can obtain more sufficient grinding opportunities, and the grinding sufficiency of the materials at the bottom is greatly improved. The stirring assembly comprises cutters and six second rotating shafts circumferentially arranged around the first rotating shaft at intervals. The cutters are arranged on the second rotating shafts at intervals in the length directions and the peripheral directions of the second rotating shafts. A groove is formed in one side of each cutter, and the opening directions of the grooves are the same as the rotating direction of the stirring assembly. In use, the grooves are filled with grinding media, the abrasion to the cutters can be reduced, and the service life of the cutters is prolonged.

Description

technical field [0001] The invention relates to the field of grinding equipment, in particular to a seven-shaft stirring mill. Background technique [0002] The stirring mill is a device that uses a stirring device to move the grinding medium to produce impact, shear, and grinding effects, thereby crushing materials. Conventional mills rely on the movement of the cylinder to drive the movement of the grinding medium, and the input power of the stirring mill is directly used for the rotation of the stirring mechanism to make the grinding medium move and crush the material, so its energy efficiency is higher than that of conventional mills and vibration mills. Agitator mills can be batch or continuous. According to the shape of the cylinder, it can be divided into groove type, ring type, vertical type and other types. [0003] Stirring mill is suitable for grinding various ores and other materials, and is widely used in mineral processing, building materials and chemical ind...
