MACHINING PROCESS FOR IRON SAND PARTICLE MODIFICATION, IRON SAND PARTICLES AND A GRINDING PANEL OF A CRUSHER

摘要

Disclosed is a machining process for iron sand particle modification, iron sand particles and a grinding panel of a crusher, the process comprising the following steps: preliminary screening particle sizes; feeding the preliminarily screened iron sand particles into the cavity of the crusher, so that the iron sand particles pile up in the crusher cavity; the crusher is driven by a motor to conduct secondary grinding and crushing of the iron sand particles; the grinding panel of the crusher stirs the iron sand particles piled up in the crusher cavity to generate and maintain corresponding extruding pressure between the iron sand particles, resulting in self-grinding between the iron sand particles stirred by the grinding panel, thereby changing the specific gravity, shapes, and surface microstructures of the iron sand particles.

1. A machining process for iron sand particle modification, comprising following steps:
S1: preliminary crushing atomized iron powder which has been reduced once, and preliminary screening particle sizes; S2: feeding preliminarily screened iron sand particles into an cavity of a crusher by using a feeder, so that the iron sand particles pile up in the cavity of the crusher; secondary grinding and crushing the iron sand particles by the crusher which is driven by a motor; and stirring the iron sand particles piled up in the cavity of the crusher by a grinding panel of the crusher so as to generate and maintain corresponding extruding pressure between the iron sand particles, resulting in self-grinding between the iron sand particles stirred by the grinding panel, and relying on the self-grinding between iron sand particles to change the specific gravity, shapes, and surface microstructures of the iron sand particles; and S3: feeding the iron sand particles into the cavity of the crusher again by using the feeder after secondary grinding and crushing, and then repeating step S2.
