Abstract

The invention provides a material classification device comprising a fan, a granulometric-class declining chamber, an airflow effuser and a feeding port. The airflow effuser is connected with the fan. The straight line of the airflow effuser intersects with the straight line of the feeding port; and the straight line of an airflow effuser opening is horizontal. A plurality of hoppers are arranged at the bottom of the granulometric class declining chamber. The diameter of the airflow effuser opening is 8-30 times of the average diameter of material granules. By the aid of high-speed airflow can be adjusted by the aid of the airflow effuser, according to the specific surface area difference of materials dropping from the feeding port, granules with different diameters are given with different horizontal moving speeds, so that different horizontal distances are obtained, and the granules optionally drop with gravity into the corresponding hoppers at the bottom of the granulometric-class declining chamber to realize the purpose of classification. Besides, the materials do not contact with any screening device bodies, relative friction force is avoided, and loss of devices is low.

Description

technical field [0001] The invention relates to the field of material grading equipment, in particular to a material grading equipment capable of real-time multi-layer grading of materials. Background technique [0002] Vibrating screening equipment (such as: linear vibrating screen, elliptical equal-thickness vibrating screen) is an important equipment for the classification of solid materials at present, and is widely used in mining, building materials, coal preparation, energy, chemical and other industries. Vibrating screening equipment generally uses the exciting force generated by the vibrator (eccentric block or eccentric shaft) to make the screen body perform periodic reciprocating vibrations along the direction of the exciting force, and the material jumps circularly on the screen surface and passes through different screens. The holes classify the materials of different specifications to the required screen surface to achieve the purpose of classification; the ampl...
