JGS型金剛石分選機是采用新分離技術的一種重選設備，根據金剛石和石墨的比重不同用無毒波將兩者分開，從石墨中選出純凈金剛石。他和常規酸煮法相比，具有成本低，效率高，投資少，省能源，降低勞動強度和無污染等特點。還可分離其他礦物。

As gravity concentration equipment integrated with new separation technology, diamond separator model JGS separate the pure diamond from graphite with non-toxic wave based on the specific gravity difference there-between. Compared with the commonly used acid boiling technique, this equipment features low cost, high efficiency, small investment, energy conservation, low labor intensity and zero pollution. Additionally, this equipment can also be used to separate other minerals.
