The article devotes to experimental study of briquetting of woodworking waste, such as sawdust and shredded bark. The aim of the work is to obtain regression dependencies linking characteristics of briquetted raw materials and parameters of moulding process with properties of produced fuel briquettes. Controlled factors of the experiment include moisture content of the raw material; average particle size of the material; percentage of sawdust and bark in the material; moulding pressure; moulding speed. The target ...

The article devotes to development of mathematical model of sawdust briquetting process, establishing relationship between the briquettes density, the moulding speed and pressing effort. The study uses elastic-viscous-plastic Bingham body stress-strain equation as a rheological model of the sawdust being briquetted, the model parameters are non-linear functions of the sawdust density; classical Runge-Kutta method was used for solving the nonlinear differential stress-strain equation. The calculations results show ...
