Granularity shaping equipment for chrome corundum production and use method

Abstract

The invention relates to the technical field of chrome corundum production, in particular to granularity shaping equipment for chrome corundum production and a using method, the granularity shaping equipment comprises a grinding box, and an open type injection opening is formed in the top of the grinding box. According to the granularity shaping equipment for chrome corundum production and the use method, a blade shaft and a gear of a mechanical fan climb along a gear ring on the surface of a sleeve and reversely drive the blade shaft and the mechanical fan to rotate, and the rotating mechanical fan carries out air suction and exhaust from bottom to top in an L-shaped air duct; dust in the grinding box penetrates through the large-aperture baffle to be sucked into the straight-through groove and the sleeve until the dust is filtered and covered on the dust filter screen, and the auger rotating forwards along with the main shaft can synchronously convey the dust in the sleeve upwards until the dust is discharged through the guide-out opening and the guide groove, so that the ground dust is cleared out in real time in the grinding process, and the grinding efficiency is improved. And the influence of dust on contact grinding of the grinding balls, the chrome corundum and the grinding box can be effectively avoided, and good grinding precision is guaranteed.

Description

technical field [0001] The invention relates to the technical field of chromium corundum production, in particular to a particle size shaping device for chromium corundum production and a use method. Background technique [0002] The main components of red corundum are α-alumina, also known as chrome corundum and ruby. Its main components are Al2O3 and Cr2O3, which form a continuous solid solution. According to the Al2O3-Cr2O3 binary phase diagram, Cr2O3 is added to the Al2O3 single-phase material. , not only did not reduce the refractoriness of the material, but the refractoriness increased with the increase of Cr2O3 content. [0003] After the production of chromium corundum, due to the different requirements for the particle size of chromium corundum used in different fields, according to subsequent applications, manufacturers generally need to use equipment such as grinders to shape the particle size of chromium corundum. The inventor found the following problems in the...
