一、用途及適用范圍

I. Purpose and Scope of Application

適用于將人造或天然的礦物晶體或微粒依形狀（圓球度）進行分級，尤其適用于人造金剛石，立方氮化硼等超硬材料的選形。利用重選原理從石墨等礦物中分選出純凈的金剛石。

This equipment is designed to grade artificial or natural mineral crystals or particles (sphericity) according to their shapes, especially for the shape selection of ultrahard materials like man-made diamond and CBN, separating the pure diamond from minerals like graphite etc. according to gravity separation principle.

三、結構與工作原理

III. Structure and Working Principle

本機由工作臺① 、振動器④ 、給料器⑥ 、分選盤⑦ 、接料器⑧ 、控制箱⑩等組成（見圖1）。其主要工作部件是一個可振動的有一定表面粗糙度的分選盤。待分選物料在盤面上受到電磁振動力、摩擦力與重力的共同作用，由于形狀不同，所受的摩擦力不同，因而在盤面的運動軌道不同，最終落到接料端不同的料斗中，完成選形過程。

This equipment is composed of work bench ①, vibrator ④, feeder ⑥, separation tray ⑦, receiver ⑧ and control cabinet etc. (see Figure 1). Its main working part is a vibratile separation tray with a certain level of surface roughness. The materials to be separated are under the effect of electromagnetic vibration force, friction force and gravity on tray surface, and finally drop into different hoppers at receiver side depending on the movement tracks due to different friction forces as a result of different shapes.
