Description

A sorting and washing device

technical field

The utility model belongs to the field of ore washing devices, in particular to a sorting ore washing device.

Background technique

The ore washing equipment currently used is generally a cylindrical washing machine. The ore beneficiation generally uses a screening machine to screen the ore material. Because of the impact of mud or other sundries on the surface of the ore, the ore is first washed in a cylindrical washing machine, and then the material is sent to the screening machine for screening, but there will be residual mud on the surface of the ore after washing, and In the subsequent conveying and screening process, the friction and collision between mineral materials will produce some mineral powders. Since the surface of the mineral materials has moisture, these mineral powders will adhere to the surface of the mineral materials to form mud stains. These mud stains will Adhering to other impurities in the mineral material, such as hard soil slag and crushed stone slag, will cause the mineral material to become larger due to the adhesion of impurities, which will affect the screening effect. Therefore, the mineral material needs to be cleaned during the screening process. At present Although there is an integrated equipment for ore washing and beneficiation, for example, the patent document publication number: CN111215384A, which discloses a kind of equipment with calcium carbonate washing and ore beneficiation, which adopts a single cylinder to realize ore washing and ore beneficiation, and performs multi-stage screening Specifically, the cylindrical ore washing machine is connected to the mineral processing screen cylinder; the mineral processing screen cylinder is from the end close to the cylindrical ore washer from near to far, followed by the tailings screening area and the secondary ore screening area. The sieve hole of the partition is smaller than the sieve hole of the secondary ore screening area, so the ore that should be under the tailings screening area will be carried to the secondary ore screening area by the coarser ore material, because the ore is in the circular ore screening area. There will be a certain thickness in the cylinder, so the use of a single drum will have the defect of missing and wrong screening, and the mud generated by ore washing will be discharged in the tailings screening area, so the mineral materials under the tailings screening area will have sticky mud stains possible.
