Embodiment Construction

[0018] Further description will be given below in conjunction with the embodiments shown in the accompanying drawings.

[0019] Such as figure 1 In the shown stirring and grinding device, the cylinder 2 is arranged horizontally and has an inlet and outlet (the inlet and outlet are provided with a sealing cover; omitted in the figure) to input and output solid-liquid two-phase flow (solid-liquid two-phase material to be processed) ), the impeller rotating shaft 11 is arranged coaxially with the drum and is rotatably positioned on the drum through the drum rolling bearing 13, several impellers 3 are fixed on the rotating shaft and located in the inner chamber of the drum, and the impeller motor 8 drives the impeller rotating shaft to make the impeller rotate; above The structure is similar to that of the existing horizontal stirring mill.

[0020] The improvement of the present invention is: the impeller shaft is also rotatably positioned on the base frame 1 through the impelle...

Abstract

The invention belongs to the technical field of mineral processing, and provides a stirring and grinding device. The stirring and grinding device has the characteristics that the grinding efficiency is improved, and the problem that the grinding effect is not uniform is solved, and can enable an output liquid-solid two-phase flow to be more even and enable the powder grinding effect to be more effective. According to the technical scheme, the stirring and grinding device comprises a roller horizontally arranged and provided with an inlet and outlet, an impeller rotating shaft coaxially arranged with the roller and rotatably positioned at the roller, a plurality of impellers fixed to the impeller rotating shaft and located in an inner cavity of the roller, and an impeller motor driving theimpeller rotating shaft to enable the impellers to rotate; and the stirring and grinding device is characterized in that the impeller rotating shaft is further rotatably positioned at a base frame, the roller is located in the base frame and is driven by a roller motor installed on the base frame, the rotating direction of the roller is opposite to the rotating direction of the impellers, and theimpeller motor is further installed on the base frame.

Description

technical field [0001] The invention belongs to the technical field of mineral processing, in particular to a horizontal drum agitating grinder for mineral processing Background technique [0002] Horizontal stirring mill is one of the main mechanical equipment for processing mineral materials. Since it came out in the 1970s, it has been rapidly used in mining, metallurgy, chemical and pharmaceutical fields with irreplaceable advantages. The horizontal stirring mill can effectively solve the problems of uneven grinding and large grinding particle size of other mills; however, the influence of the rotating speed and the structure of the stirring plate on the grinding efficiency of the horizontal stirring mill cannot be underestimated; in the current In practical application, it is often found that the grinding stirring efficiency and grinding effect of the horizontal stirring mill are not ideal. The principle of grinding is to crush the solid phase particles in the solid-liq...
