The raw cotton to be ginned is cleaned before being sent to saw-gin or roller-gin machines by passing it through a pre cleaner. The raw cotton cleaners have an important role in enchancing the cotton spinning efficiency. There are two types of raw cotton cleaners as air flow and gravity type cleaning machines. Raw cotton pre cleaning machines are analysed theoretically in this work. The effects of the geometrical magnitudes and system working parameters have been investigated.
