In modern briquette production it is very important to know the impacts of all the factors which have an influence on the final briquette quality. Briquette quality is evaluated mainly by briquette density. Briquette density is very important from the viewpoint of manipulation, burning speed, briquette stability, etc. During our research, theoretical analyses of parameters which have an impact on briquette quality, were conducted. After the completed analyses, an experiment was done to explore the behaviour of important factors. In this paper the results of the analyses and a segment of the experiment results are presented.
