Production equipment applied to environment-friendly nickel pig iron production

Abstract

The invention belongs to the technical field of nickel pig iron production, and particularly relates to production equipment applied to environment-friendly nickel pig iron production, which comprises a crushing box, two first crushing rollers are rotatably connected in the crushing box through bearings, a screen frame is arranged below the first crushing rollers, and four telescopic sleeves are symmetrically fixed at the bottom of the screen frame; the surfaces of the telescopic sleeves are sleeved with first springs, and the top ends of the first springs are fixed to the bottom of the screen frame. By arranging the driving mechanism, the through opening, the bearing plate, the shell and a second crushing roller, large raw ore which does not pass through screening can be subjected to secondary crushing, the crushing effect on the raw ore is improved, by arranging a dust treatment box, a dust removal mechanism, a conveying mechanism and a baffle, dust-containing gas generated during crushing can be filtered and then discharged, and the dust removal effect is improved. In addition, the dust removal mechanism can be used for treating the detained dust, and the situation that the dust removal effect of the dust removal mechanism is affected due to the fact that much dust is accumulated is avoided.

Description

technical field [0001] The invention relates to the technical field of nickel pig iron production, in particular to a production equipment applied to the production of environment-friendly nickel pig iron. Background technique [0002] Nickel pig iron is mainly used for steel mills to smelt stainless steel. The raw material is generally laterite nickel ore containing about 1% nickel. Laterite nickel ore is an oxide ore. At present, the domestic use is mainly from Indonesia and the Philippines. The demand of ferroalloy plants is imported. During the production of nickel pig iron, crushing devices are usually used to crush and screen large pieces of laterite nickel ore for subsequent sintering and smelting of the ore. [0003] However, when the raw ore is crushed by a crushing device in the production of nickel pig iron, a large amount of dust will be generated, which will cause dust pollution to the surrounding environment. After the original ore is screened, the larger piec...
