Theoretical analysis of the process of separating cotton particles from heavy impurities

Abstract

One of the main disadvantages of stone traps used in cotton ginning enterprises is that a certain amount of cotton falls into the pocket part during their operation. It is recommended to manually remove the cotton that has fallen into the pocket together with heavy impurities and, using air, throw it back into the pipe of the pneumatic conveying device. However, in some cases, the cotton there becomes mixed with various impurities, its trash content increases, and it becomes impossible to separate it manually. Many enterprises do not pay attention to these disadvantages, and the cotton is discarded as waste. When inspecting stone traps installed in the pneumatic conveying device during the cotton processing technological process, a number of similar disadvantages can be observed. This article analyzes these processes using the example of the cotton cleaning process, and presents a new technological solution and advantages, conclusions, and suggestions.
