Comminution of Polymetallic Nodules with a High-Pressure Water Jet. [PDF]
This paper presents an original method for the comminution of polymetallic nodules in a hydro-jet mill of our own design, having the water jet pressure in the range of 70–200 MPa. The best comminution results are ensured by equipping the mill with a water jet having a diameter dw = 0.7 mm and a comminution-homogenization tube having a diameter dh = 2.4
