A method for fragmenting and/or weakening pourable material includes guiding a material stream of pourable material immersed in a process liquid along an annular or arcuate channel past a high-voltage electrode assembly. The high-voltage electrode assembly, which includes one or more generators, generates high-voltage punctures through the material flow. Material is supplied to the material stream upstream of the high voltage electrode arrangement. Material is guided away from the material stream downstream of the high-voltage electrode assembly.

A system is disclosed. The system includes an impact processor comprising an inlet and an outlet, a secondary classifier comprising an inlet and an outlet, the secondary classifier being downstream of and coupled to the impact processor, a recirculation mixer valve downstream of and coupled to the outlet of the secondary classifier, and a recirculation line coupling the outlet of the first secondary classifier to the inlet of the impact processor.

A method for separating a particulate stream of an evaporite mineral feedstock, the method comprising passing the stream to an air classifier configured to separate the particulate stream into a fine component and a coarse component.

A method for continuous aeraulic separation of particulate materials consisting of a mixture of particles that is heterogeneous in both particle size and density is provided. The method includes grinding particles of materials, generating a gas stream conveying the ground particles, first aeraulic separation on the gas stream in order to separate the particles it contains into a first fraction consisting of the coarsest particles with variable densities and a second fraction consisting of the finest particles. A second aeraulic separation is performed on the first fraction in order to separate the particles that it contains into a third fraction consisting of the coarsest and/or most dense particles and a fourth fraction consisting of the least coarse and/or the least dense particles. A re-injecting of the third fraction or the fourth fraction at the inlet of the grinding is performed while simultaneous recovery of the second fraction as well as the fourth fraction or the third fraction, respectively, as output products.

A method of fragmenting and/or weakening of material is provided that utilizes high voltage discharges. The material is together with a process liquid introduced into a process area, in which two electrodes face each other at a distance, and is arranged therein in such a manner that the area between the two electrodes is filled with the material and process liquid. Between the two electrodes high voltage discharges are generated for fragmenting or weakening of the material. During the fragmenting or weakening, respectively, of the material, process liquid is discharged from the process area and process liquid is fed into the process area. The process liquid which is fed has a lower electrical conductivity than the process liquid which is discharged.
