The characteristic tumbling motion of these mills has given them the name 'tumbling mills', which include the ball mill, tube mill and rod mill. Ball mills are horizontal rotating cylindrical or conical steel chambers, approximately one third to half full of steel, alloy steel or iron balls, like that shown in Fig. 4.10 A–C, or flint stones.
The inserts for the ball end mills also come in three styles: a general-purpose HTM1 grade for steels up to 50 HRc, a specialized HTM2 grade meant specifically for stainless steels, and HTHM grade for hardened materials from HRc 40 up to HRc 65.Each series has unique geometry and an extremely abrasion-resistant coating for excellent performance.
