A new working media for drum mills has been tested, composed of spheroidal tetrahedrons. The experimental work took account of the influence of various technological and structural parameters and properties of the material being milled.  Experimental data show that under equal other conditions, grinding media composed of spheroidal tetrahedrons ensures higher technological performance in the milling process compared to grinding media composed of balls.
