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 calculated ore characteristics data.

A mixing arrangement, and pump for supplying small particles suspended in a liquid to form slurry for delivery includes a container, a mixing and delivery pump having a first shaft, a rotor connected to the first shaft and arranged at an inner bottom of an inner space of the container, a first power device connected to the first shaft, and a stator having stator blades. The stator surrounds the first shaft. The arrangement includes a pump having an inlet, which is located in a stator space between two stator blades, and an outlet, and an outlet pipe having a second inlet opening connected to the outlet and a second outlet opening located outside the inner space.
