Coarse powder fine grinding device for production of iron hook castables

Abstract

The invention relates to the technical field of grinding devices and discloses a coarse powder fine grinding device for production of iron hook castables. The coarse powder fine grinding device for production of the iron hook castables comprises a machine body; a protective cover is fixedly installed on the right side face of the machine body; a first power motor is fixedly installed on the top ofan inner cavity of the protective cover; an output shaft of the first power motor is fixedly connected with a first protective shaft; and the outer surface of the first protective shaft is fixedly sleeved with a first master gear. According to the coarse powder fine grinding device for production of the iron hook castables, the iron hook castables are subjected to a first pass of grinding througha second grinding roller and then are subjected to secondary grinding through a first grinding roller, the ground iron hook castables fall onto a filter board, large particles which are not sufficiently ground fall into a hopper through a discharging outlet, then the large particles inside the hopper are poured into the machine body to be ground again, and accordingly the grinding quality of theiron hook castables is prevented from being affected by the large particles, and the grinding effect of the grinding device is improved.

Description

technical field [0001] The invention relates to the technical field of grinding devices, in particular to a coarse powder fine grinding device for production of iron hook castables. Background technique [0002] Tiegou castables are made of brown corundum as the main raw material, which is properly mixed with silicon carbide, carbonaceous materials, clay, high alumina cement, ultrafine powder, admixtures, etc. It has high wear resistance and thermal shock resistance. Suitable for lining of large boilers and other high temperature kilns. [0003] In the production process, in order to prevent its coarse powder from affecting its quality, it is necessary to use a grinding device to grind the coarse powder of the iron hook castable. The existing grinding device is mostly one grinding, and lacks a filter device. During the grinding process, the coarse powder Part of the large particles in the powder cannot be ground sufficiently. These large particles will affect the production...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a coarse powder and fine grinding device for the production of iron hook castables, which has the advantages of good grinding effect, automatic lubricating oil and shock resistance, and solves the problem that most of the existing grinding devices are one grinding , and there is a lack of filtering device. During the grinding process, some large particles in the coarse powder cannot be ground sufficiently. These large particles will affect the production quality of the iron hook castable. The grinding device needs to be added regularly to prevent excessive wear of its components during work lubricating oil, and the existing grinding devices are mostly added manually, and workers forget to add lubricating oil when they are busy, which leads to greater wear of the parts of the grinding device and affects the service life of the grinding device. In addition, the existing grinding The vibration resistance of the device is poor, and the vibration force generated when the grinding device is working will make its parts loose, thus affecting the use of the grinding device
