Technical Field
The utility model relates to a dry-type magnet separator, concretely relates to dry-type magnet separator that is arranged in containing magnetite country rock magnetic iron ore to retrieve can be in the wide application of magnetite mountain iron containing country rock sorting.
Background
At present, a certain amount of rock dumping exists in part of domestic iron mines, and because the rock dumping cannot reach the required grade of a selection plant, some rock dumping is not utilized and iron-containing surrounding rocks are directly stockpiled in a dumping yard, so that a great deal of resources are wasted. With the development of the domestic metallurgical industry, a great amount of mineral resources are required, the mining capacity is continuously improved, the mine stripping ratio is increased year by year, and the amount of stripped iron-containing surrounding rocks is continuously increased. According to incomplete statistics, the stockpiling quantity of stripped surrounding rocks of mines in China currently reaches hundreds of billions of tons, and the amount of stripped iron-containing surrounding rocks of open-pit iron mines in China only reaches more than 8 billion tons every year. For example, the annual rock discharge amount of the high-village iron ore containing the martensite steel is about 1100 ten thousand tons, the annual rock discharge amount of the main earth discharge field containing the Baiyuneboite is about 3500 ten thousand tons, and the annual rock discharge amount of the iron ore in the first molten steel plant is about 4500 ten thousand tons. The iron-containing surrounding rock piles exist in a dumping site, so that a large amount of land resources are occupied, the ecological environment is damaged, and a large amount of capital needs to be invested every year for maintenance and treatment.
For a long time, the iron-containing grade of the rock discharge of the domestic iron mine stope is usually low, but due to the large quantity of the rock discharge, part of valuable resources can be recovered by proper method treatment, and the purposes of increasing the economic benefit of enterprises and saving resources are achieved. At present, most of stripped iron-containing surrounding rocks are piled up in a dumping site, but a few mine enterprises actively explore and practice in the aspect of comprehensive utilization of the iron-containing surrounding rocks.
At present, the recovery and separation of the surrounding rock containing the magnetite mainly adopts a single large dry-type magnetic separator, the processing capacity of the equipment is basically fixed, but the adaptability to the change of the feeding amount is poor. When the feeding amount is too large, the sorting effect is poor; when the amount of the feed is too small, the energy consumption per unit treatment amount is high.

the utility model is used for contain dry separator that magnetite country rock was selected separately contains dry-type magnet separator, and dry-type magnet separator installs on the dry separation platform. The method is characterized in that: the dry magnetic separator is 2, which are respectively positioned below two discharge ports of the aggregate type three-way distribution funnel, and the aggregate type three-way distribution funnel is arranged on a dry separation feeding adhesive tape platform; a dry separation concentrate funnel is arranged below a head roller of the dry magnetic separator, and the front part of the dry separation concentrate funnel is a dry separation tailing funnel; a turning plate is arranged at the bifurcation of the aggregate type three-way distribution funnel, one end of the turning plate is connected with an electric hydraulic push rod, and the electric hydraulic push rod is integrally fixed on one leg of the aggregate type three-way distribution funnel support; a dry separation concentrate platform is arranged below the dry separation platform; a fixed pull rod is arranged between the aggregate type three-way material separating funnel and the dry separation feeding adhesive tape platform. The material distributing part of the aggregate type three-way material distributing hopper adopts a crotch structure, an electric hydraulic push rod drives a turning plate to work, when the ore feeding amount is 1500-3000 t/h, the turning plate is stopped at the left side or the right side, and only 1 dry magnetic separator is adopted for operation; when the ore feeding amount is 3000-6000 t/h, the turning plate is stopped in the middle and evenly fed to the two dry magnetic separators, and the two dry magnetic separators work simultaneously.
In order to facilitate material transportation and reduce occupied area, a dry separation concentrate adhesive tape is arranged below the dry separation concentrate funnel and is vertically arranged with a dry magnetic separator, and the dry separation concentrate adhesive tape is arranged on a dry separation concentrate platform.
The utility model discloses still contain dry separation feed sticky tape, the formula of gathering materials tee bend divider funnel be located dry separation feed sticky tape front end installation.
The dry separation feeding adhesive tape and the dry separation feeding adhesive tape driving device are installed on the dry separation feeding adhesive tape platform.
And a tailing conveying rubber belt is arranged below the dry separation tailing funnel.
The utility model is used for contain after the dry separation machine that magnetite country rock was selected separately adopts above-mentioned technical scheme, have following positive effect: the aggregate type three-way material distribution funnel can selectively work or work simultaneously according to different surrounding rock metal quantities by the dry separator, is suitable for the separation requirement of large feeding quantity, and can only start one dry magnetic separator when the feeding quantity is small, so that the energy consumption is saved.
