Mathematical Modeling of the Process of Grinding Root Crops for Feeding Cattle

The results of mathematical modeling of the process of root crop shredding are presented, namely the equations of the total cutting force of the shredder with a knife wall, the total resistance to the movement of the root crop through the knife wall, the force spent on free cutting of the root crop. It is established that the cutting force should correspond to a certain condition, which allows to determine the optimal parameters of the cutting process.
