Cooperation general situation

It is the updated version(2.0) of turn-key project of Xinxiang Great Wall Machinery Corporation. The GRMS33.31 vertical mill was installed in the project. The successfully start-up of this project solved the pollution of nickel waste pills in Indonesia, and final production also can be admixture, which widely used in cement and concrete market, so as to reduce the cost of cement.

Processing flow

The pilled nickel slag was fed by forklift and conveyed by belts.

In the process of conveying, nickel slag material is de-iron and screened by a separator and vibrating screen, and then trans to vertical mill through weighing equipment and hoist.

The milled slag is concentrated by vertical mill separator, and dried by the hot air introduced from hot stove.

Dust collector collects all the qualified nickel slag particles, trans to storage silo by air chute and hoist.

The bigger particle size is conveyed back to vertical mill and re-grinding until its fineness is qualified.

Brand advantage

The lake blue color production line represents the conception of environmental harmony.

The former machines, manufactured by Xinxiang Great Wall, were painted on majestic industrial grey. But along with industrial development and regulation and more and more requirement of environment, the lake blue is painted as the main color on the equipment of the updated slag grinding plant. It represents the good wish between manufacturing and environment, and brand conception of “The Blue sky, Start from Great Wall Machinery”.
