Ginning | Cotton Ginning Process | Types of Ginning

Ginning

Ginning is the process of separating the cotton fibers from the cotton seeds. Perfect ginning operation would be performed if the separation of fibers from seed was effected without the slightest injury to either seeds or to the fiber. A cotton gin is a machine that quickly and easily separates the cotton fibers from the seeds, a job previously done by hand. These seeds are either used again to grow more cotton or, if badly damaged, are disposed of. It uses a combination of a wire screen and small wire hooks to pull the cotton through the screen, while brushes continuously remove the loose cotton lint to prevent jams. The term “gin” is an abbreviation for engine, and means “machine”.

Types of Ginning

Previous to the introduction of Modern Machinery, ginning was performed by hand or by machines of a primitive character such as the “Foot Roller” and its improvement the “Churka”.

As the cotton industry developed, greater production than these were capable of was necessary, and machines driven by power were introduced. Numerous forms of gins have been tried, but at the present time only three are used to any large extent. They are

1. Knife Roller Gin / Roller Gin
