#### Grinding | Jagdish''s Blog

Pulp viscosity has an inverse relation with the mill sound i.e. higher the viscosity, lower the sound. Pulp viscosity is a function of pulp density as well as particle size distribution in the pulp. Higher circulating load indicates a longer grinding time which means finer particles in the pulp and changes in the viscosity of the pulp as well as sound.
