Özet

Biomass is crucial for Türkiye, which has a large agricultural area and produces 55‐60 million

tons of biomass waste from its agricultural land annually. In this study, an attempt was made

to briquette nut fruit shells (walnut, almond and pistachio) using a prototype briquetting

machine and the physical quality parameters of the obtained bio‐briquettes were determined.

The nut fruit shells were briquetted using a hydraulic piston briquetting machine driven by a

PTO (power take‐off) and comprising a shredder and grinding or crushing unit with a briquetting

pressure range of 0‐190 MPa, which was developed as a prototype. The shredding unit of the

prototype machine consists of 40 hammers and 16 counter blades rotating at 2550 rpm, and

the grinding unit consists of 24 hammers and 58 counter blades rotating at 2200 rpm. The

physical and quality parameters of the bio‐briquettes, such as density, tumbler and shatter

resistance, compression resistance, water‐intake capacity, and resistance to moisture‐ were

determined. Overall, the results and factors influencing the subject of the study showed that

biomass from nut fruit shells is an excellent feedstock for the production of bio‐briquettes and

that bio‐briquettes produced with a prototype briquetting machine can be used as high‐quality

fuels.
