Embodiment Construction

[0026] Exemplary embodiments will now be described more fully herein with reference to the accompanying drawings. However, this disclosure may be embodied in many different forms and should not be construed as limited to the exemplary embodiments set forth herein. Rather, these exemplary embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. In the drawings, the same reference numerals represent the same elements.

[0027] The present invention relates to a technique of oppositely charging a first material and a second material existing as a mixture and electrostatically separating the first material and the second material from each other. The invention preferably applies to the separation of relatively small particles. The exemplary embodiments disclosed below relate to the separation of carbon (first material) and ash (second material) in coal. However, the invention i...

Abstract

Disclosed are an electric charging unit and an electroststic separation apparatus using the same. The electric charging unit allows a first material and a second material to possess opposite electric charges. The electric charging unit comprises charging balls colliding and rubbing with the first material and the second material. The charging balls meet the following conditions: the work function of the first material< the work function of the charging balls < the work function of the second material.

Description

technical field [0001] The present invention relates to a charging unit that separates different materials from each other by making the different materials oppositely charged, and an electrostatic separator (electrostatic separator) using the charging unit. Background technique [0002] Coal generally consists of carbon as a useful substance and ash including impurities such as quartz, alumina and clay minerals. Coal with a higher impurity content has a lower calorific value. For this reason, it is crucial to remove ash from coal during coal preparation. [0003] Coal preparation methods are divided into wet separation (sorting) and dry separation (sorting). [0004] The key factor to improve the separation efficiency in coal preparation is the dissociation degree of useful minerals and gangue minerals. That is to say, in order to improve the separation efficiency, it is necessary to increase the degree of dissociation, which can be achieved by ultrafine pulverization. ...
