Residence Time Distributions In Ball Mills

Residence time distributions RTDs were estimated by water tracing in a number of wet overflow ball mills diameters 038 to 465 m producing dense coalwater slurries

We are committed to building crushing, industrial grinding, ore processing and green building materials, and provides intelligent solutions and mature supporting products.
