METHOD OF CALCULATION OF PRODUCTIVITY AND POWER OF ROLL DEVICE WITH THE REGIME OF BACKUP

On the basis of the model of the process of movement and compaction of disperse mixtures in the roll gap after medium backup with a horizontal screw feeder the method of determination of integral characteristics of roller machine depending on the porosity of the working medium, its rheological properties and the structural and regime parameters of the designed device was proposed.
