A kind of grinding equipment for alumina production

Abstract

The invention discloses a grinding device for alumina production, comprising a casing, a bearing and a feed pipe are installed through the upper part of the casing, a motor is fixedly installed on the upper part of the casing, and an output end of the motor is clamped and installed with a transmission One end of the transmission shaft penetrates the bearing, a connecting sleeve is fixedly installed on the side of one end of the transmission shaft, and one end of the connecting sleeve is clamped and installed with a grinding roller, and two groups are fixedly installed on the inner side wall of the casing connecting plates, and the opposite ends of the two groups of the connecting plates are fixedly installed with clamps, and two sets of bolts are installed through the opposite faces of the two groups of the clamps. Beneficial effects: The present invention can automatically guide ungrind qualified alumina chips to the grinding range of the grinding roller through the return filter screen pipe and the set return filter screen pipe without adding a power mechanism, so that alumina production can be achieved. The use of grinding equipment is in line with the concept of green development.

Description

technical field [0001] The invention relates to the field of alumina grinding, in particular to a grinding device for alumina production. Background technique [0002] Alumina is a high hardness compound with a melting point of 2054 degrees Celsius and a boiling point of 2980 degrees Celsius. It is an ionized crystal that can be ionized at high temperatures. It is often used as an analytical reagent, dehydration of organic solvents, adsorbents, organic reaction catalysts, and abrasives. , polishing agent, raw materials for smelting aluminum, refractory materials, when actually producing alumina, it is necessary to use grinding equipment to grind it into a usable powder. The actual use of grinding equipment for alumina production has the advantages of simple operation, good grinding effect and stable use. Etc. [0003] However, the existing grinding equipment for alumina production has the following problems: when the grinding roller and the grinding stone disc cooperate wit...

AI Technical Summary

Problems solved by technology

[0003] However, the following problems exist in the application of the existing grinding equipment for alumina production: when the grinding roller and the grinding stone disc cooperate with each other to grind the alumina debris, part of the unground alumina debris will be pushed away from the grinding roller by the grinding roller. range, this part of the alumina debris cannot be further used for grinding, and manual refeeding will greatly increase the labor load. Adding a set of power mechanisms to refeed it will increase the cost of grinding equipment for alumina production, which does not meet the requirements. The concept of green and environmental protection development, secondly, the existing feeding structure cannot be added according to the amount of accumulation on the upper part of the grinding stone disc, and finally, during the grinding process of alumina, it will be partially oxidized by the extrusion force of the grinding roller and the grinding stone disc Aluminum particles splash, thus forming dust, if it is not intercepted, this part of alumina particles will directly fall to the inner bottom of the shell, and this part of alumina particles that have not been ground to pass will affect the pass rate of alumina powder products
