Grinding equipment for aluminum oxide production

Abstract

The invention discloses grinding equipment for aluminum oxide production. The grinding equipment for aluminum oxide production comprises a shell, a bearing and a feeding pipe are installed at the upper portion of the shell in a penetrating mode, a motor is fixedly installed at the upper portion of the shell, a transmission shaft is installed at the output end of the motor in a clamped mode, and one end of the transmission shaft penetrates through the bearing. A connecting sleeve is fixedly installed at the side portion of one end of the transmission shaft in a sleeving mode, a grinding roller is installed at one end of the connecting sleeve in a clamped mode, two sets of connecting plates are fixedly installed on the side wall of the interior of the shell, hoops are fixedly installed at the end portions of the opposite ends of the two sets of connecting plates, and two sets of bolts are mounted on the opposite surfaces of the two ends of the two sets of hoops in a penetrating manner. The grinding equipment for aluminum oxide production has the beneficial effects that aluminum oxide chips which are not ground to be qualified can be automatically guided to the grinding range of the grinding roller under the condition that a power mechanism is not additionally arranged through an arranged material returning filter screen pipe, so that the grinding equipment for aluminum oxide production conforms to the concept of green and environment-friendly 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 ionic 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, and 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 following problems exist in the application of the existing grinding equipment for alumina production: when the grinding roller and the grindin...

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
