Description

Multi-product ore pulp grading vibrating screen

Technical Field

The utility model belongs to the technical field of ore pulp separation, and particularly relates to a multi-product ore pulp grading vibrating screen.

Background

In chemical, metallurgical, building and food industries, it is often necessary to grade granular materials and separate the mixed materials into several strands of materials with different particle sizes. The commonly used grading equipment mainly comprises a screening machine and a grading machine. The working principle of the screening machine is that a screen is used for separating materials with different particle sizes, the materials with the particle sizes larger than the size of a screen hole are retained above the screen, and the materials with the particle sizes smaller than the size of the screen hole pass through the screen to complete the grading process of the materials. The classifier realizes the classification process of the materials by utilizing the movement difference of particles with different particle sizes in the materials in a composite force field (gravity, centrifugal force, wind power and the like).

In the field of mineral separation science and engineering, the particle size of solid particles in ore pulp directly influences the sorting behavior of minerals. Whether testing in an industrial process flow or scientific testing in a laboratory, it is often necessary to grade pulp material according to particle size. The accuracy of the subsequent trial analysis is directly influenced by the quality of the grading effect.

In laboratory scale, the ore pulp product is classified according to particle size, the most common method is manual screening, and materials with different fineness are screened out through manual screening once by using a standard screen (national test screen standard GB/T6003.1-2012) with screen holes from coarse to fine. The method is only suitable for processing a small amount of materials, and the manual screening process is complicated, intermittent operation cannot be performed, continuous operation cannot be performed, and a large amount of work needs to be performed manually and repeatedly.

Alternatively, the pulp can be treated using a small classifier to obtain underflow (coarse) and overflow (fine) products. However, the method can not classify a plurality of products through single operation, and can only solve the problems that the classified products are connected in series with classifiers with different specifications in sequence, and the separated materials have the problems of small granularity and large density or the mixture of large granularity and small density.

Chinese patent CN102463219A discloses a vibrating screen, in which the working part of the vibrating screen is fixed, the material is screened by sliding along the working face, and the screening of multi-stage products can be realized by arranging multiple layers of screens obliquely. However, the above patent is only applicable to partial dry materials, and cannot solve the classification requirements of ore pulp, such as: (1) the inclination angle of the screen body and the screen is 30-60 degrees, so that ore pulp can flow out quickly and cannot be screened effectively; (2) the number of layers of the screen is 3-6 layers in the fixed range, and the number of layers can not be flexibly adjusted according to the test requirement. (3) There is a lack of quality inspection devices and procedures for classified products.
