Method and device for effectively reducing breakage rate of lime lump materials

Abstract

The invention relates to the technical field of lime production, in particular to a method and a device for effectively reducing breakage rate of lime lump materials. The method is realized by arranging a rotating warehousing device of the lime lump materials in a silo, the lime lump materials to be warehoused are divided into a plurality of paths through the rotating warehousing device of the lime lump materials, then the lime lump materials enter into the silo through a rotating slideway and the lime lump materials are gradually paved in the silo. The device comprises a silo opening chute, a hanger and a rotating slideway, wherein the rotating slideway is connected with an outlet of the silo opening chute, and the other end of the rotating slideway is near to the outlet of the silo; and the hanger is used for suspending the rotating slideway in the silo. The rotating slideway comprises a material distributing chute, a fixed support and a rotating chute, wherein the material distributing chute is arranged at the outlet of the silo opening chute and fixed through the hanger, the rotating chute is connected with the material distributing chute, and the rotating chute is fixed in the silo through the fixed support. The method and the device for effectively reducing the breakage rate of the lime lump materials, and the rotating warehousing device of the lime lump materials is arranged in the silo, thereby effectively reducing the breakage rate of the lime lump materials and improving the finished product utilization rate of the lime lump materials.

Description

technical field [0001] The invention relates to the technical field of lime production, and relates to a method and a device for effectively reducing the breakage rate of lime blocks. Background technique [0002] Lime is widely used in the steelmaking process as a material for slagging and effective removal of S and P in the steelmaking process. At present, after the active lime produced by the lime plant is sieved, the active lime larger than 5mm is generally sent to the steel plant for use, while the active lime smaller than 5mm is crushed again and then sent to the sintering plant for use. When lime blocks larger than 5mm are put into the warehouse, secondary crushing will occur, which will increase the consumption of active lime per ton of steel in the steelmaking plant, increase the production cost, and waste mine resources. In this case, it becomes necessary to effectively reduce the breakage rate of lime block. [0003] In view of the fact that the lime block mater...
