Assessment of rational operating modes in lump peat production with a single milling-and-molding machine by the density and strength data

The modern trends in mining machine engineering dictate reduction in energy requirement of the machine operation. The quality of the product is sometimes ignored in this case. The present research aims to determine rational operating modes of an extrusion screw of a milling-and-molding machine for lump peat production with regard to the required quality of domestic fuel. To this effect, a simulation exercise on lump peat production was carried out with later determination of density and strength of a peat lump produced by the machine in the rational operating mode. The experimentation involved three values of the head coefficient which affected the strength and density of peat lumps. The lump peat density was determined using modern electronic devices with low-level default. The workbench and procedure developed for the assessment of the lump peat density ensured almost in-situ loading conditions for peat lumps. The obtained data on the density and strength of lump peat illustrate the rational mode of molding at the minimum energy requirement at the head coefficient of 2.22. Thus, the rational mode production of lump peat can minimize energy requirement, ensure the desired quality of produced lumps and reduce losses because of crumbling.

Keywords: lump peat, molding, milling-and-molding machine, energy requirement, extrusion screw, density, strength.
