  • Effects of grinding aid dosage on circuit performance and

    An enormous amount of energy is consumed for the grinding process during cement production. More than a half of the energy consumed for cement production is used for grinding process of clinker (38%) and raw material (33%). In order to decrease the greenhouse gas emission, it is critically important to reduce the energy used for comminution.
