Cold ore screening machine in sintering production

Abstract

The invention discloses a cold ore screening machine in sintering production, which comprises a screening machine body (8) and screening meshes, wherein the screening meshes comprise a large-gap bar screening mesh (1) and a small-gap bar screening mesh (2), the two screening meshes have the same overall dimensions and are parallel to each other, and the screening mesh structures of the two screening meshes both adopt bars; the bar gap of the large-gap bar screening mesh (1) is greater than that of the small-gap bar screening mesh (1), and the large-gap bar screening mesh (1) is arranged abovethe small-gap bar screening mesh (1). By adopting the technical scheme, the screening efficiency of cold sinter ore is improved, the problem that the screening holes of the single layer screening mesh are easy to block is solved and the yield of the sinter ore is greatly increased.

Description

technical field [0001] The invention belongs to the technical field of metallurgical industry production equipment, and relates to sintering process equipment in iron and steel industry production, more specifically, the invention relates to a cold ore screening machine in sintering production. Background technique [0002] At present, in the production process of the cold ore screening machine, since the single-layer screen is used, when the output of the sinter is greatly increased, or because the cold return of the sinter is too large, when the unscreened cold sinter enters the single-layer screen After sub-machine, due to the poor screening efficiency, the cold return ore cannot be completely screened out, and if the screening effect is to be improved, the mesh size of the single-layer screen has to be increased, resulting in the loss of the finished sintered ore. In addition, when the sieving gap is less than 6.5mm, the clogging of the sieve holes is also serious, which...

[0002] At present, in the production process of the cold ore screening machine, since the single-layer screen is used, when the output of the sinter is greatly increased, or because the cold return of the sinter is too large, when the unscreened cold sinter enters the single-layer screen After the sub-machine, due to the poor screening efficiency, the cold return ore cannot be completely screened, and if the screening effect is to be improved, the mesh size of the single-layer screen has to be increased, resulting in the loss of the finished sintered ore

In addition, when the sieving gap is less than 6.5mm, the clogging of the sieve holes is also serious, which affects the screening efficiency.
