To enhance dry magnetic separation of fine-grained materials, our research team developed the pneumatic drum separator (PDMS), an airflow-aided separator. Different positions at surface PDMS have varied angles, so particles different may be subjected to varying composite forces, resulting in a mismatch between airflow velocity and field intensity. However, because process is continuous certain ...

harvesting practices of potato is one of the most difficult, troublesome and sensitive stages. potatoes enter the machine with huge amounts of clod and stones: in the meantime separation of potato some stone and clod, which are the same size as of that the potatoes, shall be confide red a major problem. many methods of study by investigators are based on physical properties of potato, stone and...

seed purification is one of the important agricultural processes to obtain high quality seeds. using modern technologies help producers to do this process with higher precision and accuracy. in order to separate seed impurities, a separation machine called tribo-aero-electrostatic separator was designed. the machine was evaluated by separating impurities of flixweed (descuriania sophia). primar...

Separation of metallic and semiconducting single-walled carbon nanotubes (SWCNTs) is of great importance for SWCNT-based nano-electronics. We propose a tandem extraction strategy for efficient separation of different types of SWCNTs. This strategy is based on chiral angle discriminated adsorption of soluble condensed benzenoid aromatic molecules on SWCNTs, which induce different dispersibility ...
