High quality grinding bodies
Steel balls and rods are grinding bodies intended for ball and rod mills /dry and wet grinding/, with the help of which ore and non-ore minerals are crushed and finely ground.
The material fed into the mill is crushed by the impact of the grinding bodies and ground by the rotation between them.
