coal pelletizing process

In the pelletizing process for coal fines are rolled into balls of 5-50mm diam. The addition of 5 to 10 percent binder produces a product which after thermal drying, has sufficient stability to handling problems. This report deseribes the factor influencing the production of pellets by disc and drum type pelletizer.

Biocarbon Pellet Production: Optimization of Pelletizing

2018-6-4  The key process during pelletization is the softening of the lignin (contained in the sawdust) during compression and parallel heating, as this grants a high elastic modulus and good bonding properties of pellets (see Hu et al. 2015). Hu et al. 2015 arrived at the conclusion that moisture is a fundamental parameter in biochar pelletization. An optimal value of 20%w/w of moisture is reported together with a value of 10%w/w binder. The best binder was found to be lignin. So it can be inferred that the moisture of the material is maybe less important for torrefied biomass but it is fundamental for biochar obtained from pyrolysis. In another study Hu et al. 2016 analyze the influence on the pelletization process of the pyrolysis temperature. Through an accurate Scanning Electrone Microscope analysis Hu et al. 2016 and Hu et al. 2015 analyzed the mechanism that regulates biochar pellet
