Roller mill production system suitable for tailing treatment

Abstract

The invention discloses a roller mill production system suitable for tailing treatment, and belongs to the field of tailing treatment. The roller mill production system suitable for tailing treatment comprises a pneumatic conveyor, a raw material bin, a vertical roller mill, an air box pulse dust collector and a centrifugal fan, wherein the discharging end of the raw material bin corresponds to the feeding end of the pneumatic conveyor, the discharging end of the pneumatic conveyor corresponds to the feeding end of the vertical roller mill, the discharging end of the vertical roller mill corresponds to the feeding end of the air box pulse dust collector, and the air outlet end of the air box pulse dust collector is communicated with the air inlet end of the centrifugal fan. According to the roller mill production system suitable for tailing treatment, the pneumatic conveyor, the raw material bin, the vertical roller mill, the air box pulse dust collector and the centrifugal fan are adopted, so that the roller mill production system can conduct efficient roller mill machining on tailings, and the production process is stable, efficient, energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the field of tailings treatment, in particular to a roller mill production system suitable for tailings treatment. 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 w...

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

If the belt conveying device in the above-mentioned vertical mill production system is directly replaced by a traditional pneumatic conveying device, since the traditional pneumatic conveying device is mainly used to transport small and light mineral powder, when the mineral agglomerates and When increasing its volume and weight, the traditional pneumatic conveying device needs to strengthen the wind force to drive the agglomerated minerals for transmission. This pneumatic conveying device consumes a lot of energy, has low energy utilization rate, and poor transmission effect, resulting in waste of resources and insufficient energy saving.
