The main factor contributing is the shear force applied by the balls. Using only shear force, one can produce large graphene flakes. The secondary factor is the collisions that occur during milling. Harsh collisions can break these large flakes and can potentially disrupt the crystal structure resulting in a more amorphous mass.

The ball mill is a device that destroys the raw materials again after they are mined or broken into small pieces to make their particles smaller. From its name, it can be understood that the ball mill is equipped with steel balls in a closed cylinder. Through the rotation of the cylinder, the steel balls fall from high places and collide with ...

In grinding operation, the consumption of ball mill steel ball is very large, about 10 times more than that of ball mill liner. In order to make up for the loss of steel ball and keep the ball load particle size constant in the ball mill, it is necessary to add steel ball regularly according to a certain proportion.
