Up-Gradation and Improvement of Cotton Ginning Machinery

摘要

Cotton producing countries are seeking ways and means to boost their exports, essentially to strengthen their economics. Although Pakistan is playing a key role in world cotton trade and production yet facing challenges due to quality and high cost of ginning. One of the major problems faced by the ginning sector is old technology of cotton ginning and lack of standards. Prime objective of this project was to doctor up the ginning machinery and standardize critical parts. A gin stand was design, developed and got fabricated. In the up-graded ginning machinery, output of cotton lint per saw was 6.26 kg/hour comparing 2.77 kg/hour for conventional plant which resultantly doubled the ginning output per gin stand. The improved ginning machinery produced 5 bales per hour, consumed 35 % less electricity by saving 2.81 kW per bale. It also saved 60 % in terms of labour cost. Compact structure of the machine made it safe and user friendly. Development and introduction of fixtures and gauges also facilitated the assembly as well as reduced repair cost and factory down time.
