SEPARATING SOLIDS FROM SOLIDS; SORTING

Description

B07 covers mechanical separation and sorting processes that divide solid materials into distinct groups based on physical properties such as size, density, shape, or composition. This class encompasses screening equipment, classifiers, density separators, and sorters used across industries including mining, agriculture, waste management, and manufacturing. Excluded are wet separation methods (classified under B03) and magnetic or electrostatic separation of particles (B03B, B03C), though the boundaries with B03 can overlap for combined wet-dry processes.

IPC and CPC are identically structured here. All 2 subcodes exist in both systems.

2 shared codes have differing titles between IPC and CPC.
