Nov 01, 2011 1. Introduction. Biomass has been defined to be any material, excluding fossil fuel, which was a living organism that can be used as a fuel either directly or after a conversion process .The use of biomass as source of fuel dates back to Peking Man, 460,000 to 230,000 years ago Binford and Ho 1985, and the use of plant biomass as a fuel for heat, light, and food preparation
The unpacked biomass, freed from its impurities, is crushed and shredded by grinding mills and a grinding sieve, and flows into a pump receiver tank, from where it either flows directly into a storage tank or can be pumped out.

Sep 15, 2019 The most important factor determining suitable technology for biomass size reduction is the initial moisture content in the material , and initial particle size . Biomass grinding is still a challenging procedure in the industry, many additional pre-treatment techniques are applied to increase the initial raw biomass grindability 21 .
Dec 27, 2014 Biomass densification technologies. Grinding, briquetting cubing, and pelletizing are three physical densification processes with differences in the levels of output biomass density. All physical densification processes have three major steps
Biomass is a promising renewable energy resource despite its low energy density, high moisture content and complex ash components. The use of biomass in energy production is considered to be approximately carbon neutral, and if it is combined with carbon capture technology, the overall energy conversion may even be negative in terms of net CO 2 emission, which is known as BECCS

The clean biomass is then ground in a hammer mill or chipped to a uniform size, which must be less than the thickness of the pellet that will be produced. Grinding down biomass helps to reduce the horsepower the pellet mill must produce. If the biomass is high in moisture, it must be dried to approximately 10 percent moisture content.
