A drum type magnetic separator with roughing and sweeping functions

Abstract

A cylinder magnetic separator with roughing and scavenging functions belongs to the technical field of magnetic separation devices, and is used for efficient ore separation. The technical scheme of the cylinder magnetic separator is characterized in that the front end and the rear end of a cylinder are respectively supported by a rotating bearing and a carrying roller, an ore feeding pipe and an ore discharging water pipe stretch into the body of the cylinder from the front end of the cylinder, a concentrate bucket is arranged below the ore discharging water pipe, the discharging end of the concentrate bucket stretches out from the rear end of the cylinder body, the lower portion of the rear end of the roller is provided with a mine tailing collecting tank, and a roughing magnetic system and a scavenging magnetic system are fixed below the outer side of the cylinder. The magnetic system is arranged outside the cylinder, and the action area and the intensity of the magnetic system are increased, so the sorting area is greatly increased, and improvement of the concentrate recovery rate and control of the mine tailing grade are highly facilitated; a double-magnetic system structure is adopted to effectively roughly sort weak magnetic mineral from ore sands, so the magnetic separation recovery rate is improved; and a magnetic system outside arrangement structure can realize super enlargement of a cylinder magnetic separator, so the single machine processing capacity of ores is greatly improved.

Description

technical field [0001] The invention relates to a drum-type magnetic separator with roughing and sweeping functions, and belongs to the technical field of magnetic separation equipment. Background technique [0002] In the production process of iron ore, magnetic separation is an important production link of beneficiation. At present, there are many kinds of magnetic separators, which can be divided into dry type high magnetic field magnetic separator, flat ring type high magnetic field magnetic separator, SHP wet type high magnetic field magnetic separator, vertical ring wet high magnetic field magnetic separator. The general structure of these magnetic separators is to use a drum with a built-in magnetic system. During the rotation of the drum, the magnetic system will absorb the iron-containing particles in the ore on the outer wall of the drum. The water pipe or scraper is collected into the concentrate tank for discharge. The disadvantages of the drum magnetic separat...

AI Technical Summary

Problems solved by technology

The disadvantages of the drum magnetic separator with built-in magnetic system mainly include the following points: First, the drum magnetic separator with built-in magnetic system has a small separation area and a short separation belt, which leads to low processing capacity of the magnetic separator. The concentrate recovery rate in the ore is low, while the iron ore contained in the tailings is of high grade; secondly, due to the large mass of the magnetic system, the magnetic system is built in the drum, resulting in a large spindle load of the drum, which makes the drum type It is difficult to achieve super-large magnetic separators, which affects the increase in the processing capacity of a single machine

Because the drum-type magnetic separator with built-in magnetic system has the above shortcomings, which limits the production capacity of the magnetic separator, it is necessary to improve the drum-type magnetic separator with built-in magnetic system to meet the needs of large-scale production
