Description

Technical Field

[0002] Metallurgical slag refers to various solid wastes generated in the production process of the metallurgical industry, mainly blast furnace slag produced in ironmaking furnaces and various non-ferrous metal slags produced by non-ferrous metal smelting. The magnetic separation device is a key equipment in the recovery of metallurgical slag. For metallurgical slag in a sandy state, it is often necessary to screen it through a magnetic separation device during the recovery process to obtain important metal materials.

[0003] At present, the utility model with patent number CN201921206294.8 discloses a magnetic separator for recycling metallurgical waste slag, including four sets of legs, a recycling box, a feed pipe, a hopper, a discharge pipe, a motor, a reducer, a rotating shaft, a magnetic roller, a fixed shaft and a scraper; it also includes a left hanging plate, a right hanging plate, a support plate, a left hydraulic cylinder, a right hydraulic cylinder, a pad, a left limit rod, a right limit rod, a front baffle, a rear baffle, a right baffle, a recycling pipe, an upper fixed rod and a lower fixed rod.
