Example Embodiment

[0013] The production equipment used in this process is figure 1 Install the spare as shown.

[0014] After the production equipment is ready, when the processing and production of ferrosilicon powder is required, the centrifugal fan 15 is started. Put it into the hopper 4, and send it into the high-frequency vibration mill 1 through the material pipe 2 through the screw feeder 3 for ultra-fine crushing. And the material pipe 8 is sent into the multi-stage screening machine 7 for screening. After the ferrosilicon powder is screened and classified, the qualified part is transported into the storage tank 13 through the material pipe 12, and the unqualified part is passed through the material pipe 5 and the material. The pipe 6 is sent into the screw feeder 3 to be superfinely pulverized again. The said material pipes 2, 5, 6, 8, 9, 12 and the high-frequency vibration mill 1, cyclone discharger 10, and more connected to it. The grade screening machine 7 together constitutes a f...

Abstract

A technology for continuously preparing the ultramicro or superfine ferrosilicon powder includes such steps as precrushing the ferrosilicon, pulverizing by high-frequency vibration grinder, multi-class cieving for classifying, storing the qualified powder in collector, returning the unqualified particles back to said ginder. Its system is composed of feeding pipe, HV vibration grinder, cyclone unloader, and multi-class sieving unit.

Description

technical field [0001] The invention relates to a processing method for ultra-fine crushing and grinding of solid metal, in particular to an ultra-fine and ultra-fine continuous processing process of ferrosilicon powder. Background technique [0002] Ferrosilicon alloy powder is used as a suspension medium in the mineral processing industry, and there is no more research on its pulverization processing at home and abroad. The crushing of ferrosilicon is limited by many conditions, and its most notable feature is that it is easily oxidized when crushed to a certain particle size, and the oxidized ferrosilicon powder will lose its original function. Therefore, the material temperature must be strictly controlled to prevent its oxidation. Most of the existing technologies rely on high-frequency vibrating mills for intermittent production. To crush ferrosilicon powder with a single machine to achieve the required particle size of the finished product, measures such as vacuuming...
