Abstract

The utility model belongs to the dry type separation field, particularly a grading screen net for a dry type big block magnetic separator. The utility model is composed of a 1# screen net, a material conveyer belt, a two-stage magnetic separator, a 2# screen net, a three-stage magnetic separator and a one-stage magnetic separator. Screen nets with different specifications are added on the existing multistage magnetic separators, thereby, the utility model realizes the purposes of mineral concentration, granularity separation and gradation, and overcomes the defects of the existing magnetic separators. The grading screen net for a dry type big block magnetic separator enhances the ore selecting rate by 3-8%, saves resources, and improves the process flow after ore concentration.

Description

The classification screen cloth of the big lumpiness magnetic separator of dry type

One, technical field:

The utility model belongs to the dry type separation field, relates to the classification screen cloth of the big lumpiness magnetic separator of a kind of dry type specifically.

Two, background technology:

At present, in the exploitation and stripping rock process of magnetic iron ore, it is very serious that part ore and ground are mixed the waste resource phenomenon that abandons, also have and adopt the existing big lumpiness magnetic separator of conventional dry can only from roach, the ore that abandons be regardless of granularity, elect with being regardless of grade, want the branch granularity, classify and also need continue to increase screening machine and grader, ore deposit after the classification can not in time be transported and mix, and has both increased equipment and manpower, wastes power again.

Three, summary of the invention:

The purpose of this utility model is the screen cloth that has increased different size on original multi-stage magnetic separation machine, has realized both ore dressings, divides granularity, graduate purpose again, to overcome above-mentioned deficiency.

The purpose of this utility model is realized by following technical scheme:

The classification screen cloth of the big lumpiness magnetic separator of a kind of dry type comprises: one-level magnetic separator, secondary magnetic separation machine, three grades of magnetic separators, screen cloth are characterized in: 1 ^#The frame upper and lower end that the screen cloth upper end is fixed under the one-level magnetic separator upper roller axis tilts to be fixed on the following methods, rack of one-level magnetic separator 2 ^#The frame upper and lower end that the screen cloth upper end is fixed under the secondary magnetic separation machine upper roller axis tilts to be fixed on the following methods, rack of secondary magnetic separation machine; Can fix 3 on the multi-stage magnetic separation machine as required ^#Screen cloth, 4 ^#Screen cloth, 5 ^#Screen cloth; To single-stage magnetic separator, 3 ^#The online end of classifying screen is fixed on frame upper and lower end under the single-stage magnetic separator upper roller axis and tilts to be fixed under the single-stage magnetic separator on the methods, rack.

Adopt the classification screen cloth of the big lumpiness magnetic separator of the utility model dry type, improved the ratio of sorting and cleaning 3-8% of ore, both saved resource, improved ore dressing post-order process flow process again, also improved economic benefit.

Five, the specific embodiment:

Embodiment:

The classification screen cloth of the big lumpiness magnetic separator of the utility model dry type is by 1 ^# Screen cloth 1, material conveyer belt 2, secondary

magnetic separation machine

3,2 ^# Screen cloth 4, three grades of magnetic separators 5, one-level magnetic separators 6 are formed, and be characterized in: the frame upper and lower end that 1# screen cloth 1 upper end is fixed under the one-level magnetic separator 6 upper roller axis tilts to be fixed on the following methods, rack of one-level magnetic separator 62 ^#The frame upper and lower end that screen cloth 4 upper ends are fixed under the secondary magnetic separation machine 3 upper roller axis tilts to be fixed on the following methods, rack of secondary magnetic separation machine 3; Can fix 3 on the multi-stage magnetic separation machine as required ^#Screen cloth, 4 ^#Screen cloth, 5 ^#Screen cloth; To single-stage magnetic separator, 3 ^#The online end of classifying screen is fixed on frame upper and lower end under the single-stage magnetic separator upper roller axis and tilts to be fixed under the single-stage magnetic separator on the methods, rack.

During use, material from the one-level magnetic separator 6 by after being transported to the upper roller magnetic separation, through 1 ^# Screen cloth 1 is fallen on the material conveyer belt 2, same be transported to the upper roller magnetic separation of secondary magnetic separation machine 3 by material conveyer belt 2 after, through 2 ^# Screen cloth 4 is fallen on the material conveyer belt 2, and the ore after the classification is in time transported, and in like manner can also can adorn screen cloth as required and continue screening on three grades of magnetic separators 5, and method of operating in like manner if select the single-stage magnetic separator for use, only needs 3 ^#The online end of classifying screen is fixed under the upper roller axis of single-stage magnetic separator on the support, and the lower end is fixed on the below support of single-stage magnetic separator, both can reach the purpose of classification screen cloth.
