Embodiment Construction

[0034] The following is attached figure 1 The application is described in further detail.

[0035] The embodiment of the present application discloses a slag fine powder production line. refer to figure 1 , the slag powder production line includes a feeding belt 110, a vertical mill 120, a hot gas furnace 130, a cooling bin 160, a finished product bin 140, a recovery bin 150 and an air delivery system 200; The feeding end of the feeder is connected, and the water slag can be transported to the vertical mill 120 through the feeding belt 110, and the vertical mill 120 grinds the water slag into slag powder. The gas outlet of the hot gas furnace 130 communicates with the gas inlet of the vertical mill 120. When the vertical mill 120 grinds water slag, the hot gas furnace 130 fills the vertical mill 120 with hot air to dry the slag powder.

[0036] The air delivery system 200 includes a feeding pipeline 210 and a filter system 230. The filtering system 230 includes a pulse dust...

Abstract

The invention belongs to the technical field of superfine slag powder production and relates to a superfine slag powder production line. The superfine slag powder production line comprises a feeding belt, a vertical mill, a hot air furnace, an air conveying system and a finished product bin; the output end of the feeding belt is communicated with the feeding end of the vertical mill; the output end of the hot air furnace is communicated with the air inlet end of the vertical mill; the air conveying system comprises a feeding pipeline, an induced draft fan and a filtering system; the filteringsystem comprises a pulse dust collector; the feeding end of the feeding pipeline is communicated with the discharging end of the vertical mill; the discharging end of the feeding pipeline is communicated with the air inlet end of the pulse dust collector; the discharging end of the pulse dust collector is communicated with the finished product bin; and the induced draft fan is fixedly connected into the feeding pipeline. According to the mineral slag micro-powder production line of the invention, the contact time of hot gas and superfine slag powder can be prolonged, the contact area of superfine slag powder and the hot gas is increased, the drying efficiency and effect of the superfine slag powder are improved, and the water content in the finished superfine slag powder is reduced.

Description

technical field [0001] The application relates to the field of slag fine powder production, in particular to a slag fine powder production line. Background technique [0002] Slag fine powder refers to a powdery product obtained by superfine grinding the water-quenched slag discharged from the ironmaking blast furnace. The slag powder after ultra-fine grinding is mixed into cement or concrete according to a certain proportion, thereby greatly improving the density of cement concrete, and at the same time converting the lower-strength calcium hydroxide crystals into higher-strength calcium silicate hydrate. Glue can significantly improve the comprehensive performance of concrete and cement products; or mix fluorine gypsum and quicklime into slag powder according to a certain proportion to form cement powder, which can be used to backfill the mine. [0003] At present, the announcement date is June 26, 2020, and the Chinese utility model patent with the announcement number CN...
