## The compression ratio in briqueting is

May 07, 2020

Jul 09, 2020 The compression ratio K is the ratio of the dumping height in the die (h bulk) to the height of the briquettes at maximum pressure (h p max). The densification energy W V of the briquetting process is the integral of the pressure-displacement diagram
