Coal gangue separation system based on density measurement

Coal gangue separation is an essential part of the development and utilization of coal. A method of separating gangue from coal based on the density by calculating volume and weight of the ores which is measured by the designed equipment was given in this paper. The working principle of the separation method was described firstly, then the system composition of the separation system was introduced, further more, the main influence factors of the separation accuracy were analyzed.
