This work aims to improve the uniformity of the grinding polymer materials (recycling of thermoplastic polymers)
and reduce the power consumption of the grinding process for the polymer recycling process. The uniformity of
grinding polymer materials is considered in many ranges: technical, material and control (steering). The influence
of the method and grinding agent, the susceptibility properties and homogeneity of the grinded material was
illustrated in this search. Irregularity of the operation of the dosage (feeder) of the granular material (?) depends
on the diameter (D) and the screw pitch (S). The uniformity of grinding polymer materials increases when the S/D
is 0.25 or 1.67. The uniformity of grinding polymer materials for the S/D of 1.67 is better than for S/D of 0.25.
