Comprehensive production process for tailing micro powder

Abstract

The invention discloses a comprehensive production process for tailing micro powder, and belongs to the field of tailing treatment. The comprehensive production process comprises a tailing discharging and conveying step, a tailing grinding step and a tailing finished product storage and bulk step, in the tailing discharging and conveying step, slag and mineral powder in tailings are efficiently and reliably conveyed to the tailing grinding step through a first pneumatic conveyor, the tailings are rolled into tailing micro powder through a vertical roller mill, a centrifugal fan drives an air box pulse dust collector to collect the tailing micro powder, then the gathered tailing micro powder is conveyed into the tailing finished product storage and bulk step, the tailing micro powder is conveyed into a finished product bin through a second pneumatic conveyor to be stored, and sub-packaging forming is carried out according to requirements. According to the comprehensive production process for the tailing micro powder, operators can efficiently utilize the tailings to prepare the tailing micro powder, and the production process is efficient, reliable, clean and environment-friendly.

Description

technical field [0001] The invention relates to the field of tailings treatment, in particular to a tailings micropowder comprehensive production process. Background technique [0002] Chinese Patent Document Publication No. CN108855557B discloses a switchable vertical mill production system for producing cement or slag, which is used for grinding cement clinker or slag, wherein the switchable vertical mill production system for producing cement or slag includes: feed device for feeding cement clinker or slag; at least one vertical mill connected to the feeding device for grinding cement clinker into cement or slag into mineral powder; bag filter, Connected with the vertical mill, the bag filter is used to collect cement or mineral powder; the high-pressure fan is installed at the corresponding position of the bag filter, and the high-pressure fan is used to drive the cement or mineral powder in the vertical mill into the bag filter; convey The device is connected with the ...

AI Technical Summary

Problems solved by technology

[0003] However, the above-mentioned vertical mill production system uses an open belt conveying device to transport the mineral materials. During the transportation process, the dust pollution is large, and the fine particles of the mineral powder are easy to be lifted up due to vibration, wind or other external forces, resulting in resources. waste

In addition, it is difficult for the above-mentioned vertical mill production system to be in the transmission process. After the fan is started, it is easy to attract the mineral powder in the bag filter, so that the mineral powder is discharged together with the gas of the fan, and it is easy to form dust pollution.
