Description
An on-line system of automaticly discriminating and separating the gangue from coal is introduced based on the principle of double photon absorptiometry. It is applicable to a coal pit with annual output of 1.2 x 106 t. The size of sample ore is 50∼150 mm, and the conveyor speed is less than 1 m/s. During the test run it is shown that the accuracy of separating gangue is better than 90%. In principle, this separator is also suitable for the sample ore of 20∼50 mm size
