Ground slag processing production line

Abstract

The invention provides a ground slag processing production line. A pretreatment tower, a first screening tower, a second screening tower and a third screening tower are sequentially arranged along a forward direction of the production line; a first conveying machine is arranged between the pretreatment tower and the first screening tower, and penetrates through a magnetic separation station; a second conveying machine is arranged between the first screening tower and the second screening tower; a third conveying machine and a fourth conveying machine arranged side by side are arranged betweenthe second screening tower and the third screening tower; a first vibrating screen and a first crushing machine are arranged in the first screening tower; a second vibrating screen, a second crushingmachine and a first material output system are arranged in the second screening tower; and a third vibrating screen and a second material output system are arranged in the third screening tower. According to the ground slag processing production line provided by the invention, ground slags are screened, crushed and magnetically-separated for multiple times through the pretreatment tower and the three screening towers, so that the intensification, the productization, the high efficiency and the environmental protection of a ground slag processing technology are realized.

Description

technical field [0001] The invention relates to a ground slag processing technology, in particular to a ground slag processing production line. Background technique [0002] Metallurgical steel plants discharge about 100 million tons of iron and steel slag every year. When the iron and steel slag is discharged, it is liquid and molten. It not only contains a lot of heat, but also has about 10% impurity residual steel (so-called "impurity" - slag Iron-coated, iron-coated slag forms), and a large number of oxide complexes and beneficial elements and many other useful ingredients. Moreover, many steel slags need to be piled up in large quantities because they have not been effectively processed and utilized, which not only directly occupies a large amount of farmland, but also has a large amount of dust and rainwater washing away, causing calcium oxide to dissolve in water, causing the nearby soil to become alkaline, and the pH value of nearby waters or rivers It has seriously...

Problems solved by technology

Moreover, many steel slags need to be piled up in large quantities because they have not been effectively processed and utilized, which not only directly occupies a large amount of farmland, but also has a large amount of dust and rainwater washing away, causing calcium oxide to dissolve in water, causing the nearby soil to become alkaline, and the pH value of nearby waters or rivers It has seriously polluted the surrounding environment and constituted a difficult point in the environmental management of iron and steel enterprises.
