Description

Multifunctional crushing and screening device for furnace slag

Technical Field

The invention relates to the technical field of slag treatment, in particular to a multifunctional slag crushing and screening device.

Background

The slag is also called as dissolving slag. The melt floating on the surface of liquid materials such as metals and the like generated in the pyrometallurgical process mainly comprises oxides (silicon dioxide, aluminum oxide, calcium oxide and magnesium oxide), and often contains sulfides and carries a small amount of metals.

The components of the slag are adjusted by adding proper amount of flux (lime, quartz, fluorite, etc.). During the smelting process, the components and properties of the slag are controlled, so that gangue and oxidized impurity products can be smoothly separated from molten metal or sulfur, harmful impurities in the metal are removed, non-metallic inclusions in the liquid metal are absorbed, the liquid metal is not directly polluted by furnace gas, and useful metal oxides are enriched; it is also a resistance heating element in electric furnace smelting. The slag plays a decisive role in ensuring smooth smelting operation, quality of smelting products, metal recovery rate and the like, for example, the method of smelting steel after slag is refined is used in steelmaking operation.

According to different metallurgical processes, the furnace slag can be divided into smelting slag, refining slag and synthetic slag; the slag includes alkaline slag, acid slag and neutral slag according to its properties. Many slags have significant utility. For example, blast furnace slag can be used as a cement raw material; the high phosphorus slag can be used as fertilizer; the vanadium-containing slag and the titanium-containing slag can be respectively used as raw materials for extracting vanadium and titanium, and the like. Some slags can be used to make slag cement, slag brick, slag glass, etc.

The quantity of waste slag generated in the smelting process is large, for example, about 0.3-1 ton of blast furnace slag is generated when 1 ton of pig iron is produced; producing 1 ton of anode copper from copper concentrate produces about 5-6 tons of smelting slag. The waste slag which is not returned to the basic smelting process is comprehensively utilized.

When the slag is recycled, the slag needs to be crushed into powder so as to facilitate the subsequent recycling of the slag. However, most of furnace slag is crushed at present and is directly poured into a crushing box for crushing, so that blockage is easily caused, and batch continuous crushing is inconvenient; and the crushing precision is low, the crushing is not uniform, and the wide application is not convenient.

Based on the above, the invention designs a multifunctional slag crushing and screening device to solve the problems.
