Ore screening machine

Abstract

The invention discloses an ore screening machine. The ore screening machine comprises a screening box, a rotating column, a rotating motor, a primary screening disc, a fine screening box and a guide plate, wherein the rotating column is arranged at the top of the screening box and penetrates through the screening box; the rotating motor is connected to the top of the rotating column; the primary screening disc is connected to the bottom of the rotating column; the fine screening box is arranged at the bottom of the primary screening disc; and the guide plate is spirally arranged along the inner wall of the screening box. The ore screening machine is provided with multiple powder screening devices, and can achieve various screening of powder.

Description

technical field [0001] The invention relates to the field of ore screening devices, in particular to an ore sorting machine. Background technique [0002] In the steel production process, the sintering process is carried out first. Sintering is a process in which powder or powder compact is heated to a temperature lower than the melting point of its basic components, and then cooled to room temperature in a certain method and speed. As a result of sintering, bonding occurs between powder particles, the strength of the sintered body increases, and the aggregates of powder particles become aggregates of crystal grains, thereby obtaining products or materials with required physical and mechanical properties. [0003] Before powder sintering, it is necessary to break the ore into ore powder, and then mix various powdery iron-containing raw materials with an appropriate amount of fuel and flux, add an appropriate amount of water, and mix and pelletize them on the sintering equip...

Problems solved by technology

[0004] However, after the existing ore powder is pulverized, the fine powder is sieved after the initial sieving, and the coarse ore is not redundantly sieved, which will cause a lot of coarse ore to be crushed together, and the re-crushing still uses For the original crushing device, if a small crushing machine is used, large coarse ore will cause damage to the device, but using a large crushing machine for rough ore consumes a lot of power and consumes a lot of energy.
