Soft Monitoring of a Coal Separation Process

A simulation analysis of a new method to identify a coal gravitational separation process is presented in the paper. The washability characteristic of a raw coal, the partition curve of a washing machine and separation densities have been identified. On-line identification is performed with the use of a soft monitoring system consisting of belt scales for yield measurements of products, on-line radiometric ash monitors and software interpreting these measurements. The method has been tested using a simulation model for the three-product coal separation process in a jig
