Sedimentation balances are distinguished by higher sensitivity compared to other sedimentation analysis instruments, and if we discard the overly complex automation, then they retain simplicity of design. However, the difficulty of proper decoding obtained from analyzing the diagram reduces these advantages. A graphical solution to the problem of determining the yields of individual fractions by drawing tangents to the sedimentation curve gives figures that are only approximate and not sufficiently reliable. But if the analyzed material has a certain pattern in the distribution of grains by size, then the problem of establishing the granulometric characteristics is solved analytically, more accurately and relatively simply. Numerous studies have undoubtedly established the presence of such a pattern in the products of grinding homogeneous (monomineral) rocks.
