The kinetic energy of the hammer is proportional to the weight of the hammer, that is, the heavier the hammer, the greater the kinetic energy of the hammer and the better the crushing effect. However, the heavier the weight of the hammer, the greater the centrifugal force generated by the rotation, which increases the load on the rotor and other parts of the Single shaft hammer mill accordingly. On the contrary, if the hammer is too light, the kinetic energy of the hammer will be small, the breaking capacity will be weakened, and even the hammer will be easily overloaded during work, thereby accelerating the wear of the pin shaft.

The shape and material of the hammer also have a certain influence on the granulation effect. Due to the sharp impact surface of the top of the hammer, the "T"-shaped hammer not only has a good impact effect, but also has a better tearing effect than the square, stepped and three-convex hammers. In addition, if the hammer is not wear-resistant, the crushing effect of the worn hammer will be poor, and the resulting colloidal particles will be large and uneven, thereby affecting the drying of the colloidal particles.
