Grinding device for finish machining of ores

Abstract

The invention discloses a grinding device for finish machining of ores. The grinding device for finish machining of the ores comprises a grinding box body; a bearing is clamped in the middle part of the upper surface of the grinding box body; a rotating shaft is sleeved with the bearing; the top of the rotating shaft is fixedly connected with an output shaft of a driving device; the lower surfaceof the driving device is fixedly connected to the upper surface of the grinding box body; a plurality of crushing blades are fixedly connected to the left and right side surfaces of the rotating shaft; and the crushing blades are positioned in the grinding box body. The grinding device for finish machining of the ores, disclosed by the invention, has the advantages that ore raw materials penetratethrough small holes in a screening plate to fall into a grinding groove by arranging the driving device when the ore raw materials are small to a certain degree; a grinding disc can also be driven torotate at a high speed in the rotating process of the rotating shaft so that the ore raw materials in the grinding groove can be ground and machined; the ore raw materials entering the grinding box body are crushed and ground in sequence so that the grinding effect and the grinding efficiency of the grinding disc can be both guaranteed.

Description

technical field [0001] The invention relates to the technical field of grinding equipment for mineral smelting, in particular to a grinding device for finishing ore. Background technique [0002] Ore refers to mineral aggregates from which useful components can be extracted or which have certain usable properties. It can be divided into metallic minerals and non-metallic minerals. The unit content of useful components in an ore is called ore grade. Precious metal ores such as gold and platinum are expressed in grams or tons, and other ores are often expressed in percentages. [0003] Ore often needs to be ground into powder with the help of a grinder, and then pure metal is extracted, but the existing grinder usually does not have the crushing function, and because of the high hardness of the metal ore, it is difficult for some large ores to enter In the grinding groove, thereby reducing the grinding efficiency of the grinding disc, it will also affect the grinding effect ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a finishing ore grinding device, which solves the problem that the existing grinding machines usually do not have the crushing function, and because the hardness of the metal ore is relatively high, it is difficult for some large ore to enter into the grinding tank, which reduces the grinding efficiency of the grinding disc, and also affects the grinding effect of the grinding disc
