  • Method and an arrangement for controlling of a comminution process having a grinding circuit
    Patent number: 10406532
    Abstract: An arrangement for controlling a comminution process having a grinding circuit, includes an imaging system measuring 3D reconstruction measurement data for three-dimensional reconstruction of incoming ore; a particle size analysis equipment measuring particle size data for calculation of the particle size characteristic value of outgoing ore; an ore characteristics data calculation block receiving a particle size distribution profile of incoming ore and a particle size characteristic value of the outgoing ore, the particle size distribution profile being calculated and/or reconstructed from the 3D reconstruction measurement data for three-dimensional reconstruction, and the particle size characteristic value being calculated based on the measured particle size data, the ore characteristics data calculation block calculating ore characteristics data based on the particle size distribution profile and the particle size characteristic value; and a control block controlling the grinding circuit based on the calcu
