what is resistance to wear rod mill

The faster the mill speed, the greater the wear on the rods and liners so, the general rule of thumb for rod mills is to operate no faster than the speed that will obtain the desired product size the operation speed of rod mills is generally determined by the peripheral speed of the inside of the mill generally, rod mills operate between
