Self-Grooving Rubber Roller for Double Roller Gin

Description and Salient Features :

Ginneries are presently using chrome composite leather rollers. The disadvantages with these rollers are lack of consistent output due to faster wear, requirement of periodical grooving which is laborious and involves high downtime, chromium contaminates lint and is hazardous to workers. Self-grooving rubber roller is developed to overcome the problems encountered in chrome composite leather roller. Self-grooving rubber roller can be used as an alternate roller to chrome composite leather roller for use in roller gins. With suitable modifications, conventional DR gins can adopt self-grooving rubber roller.

Salient Features: 

• Roller made with nitrile rubber having radial layers of softer rubber compound to form grooves 
• Comprises of three parts viz. inner hard core, outer ginning body and soft groove area. 
• Optimum roller speed: 40 rpm. 
• DR gin output: Lint output with self-grooving rubber roller is about 25-30% higher than conventional leather roller 
• Three times more durable than conventional leather roller

Stakeholders : Cotton ginning industries, Gin machinery manufacturers 

Benefit to Stakeholders : 

• Increased (25-30%) and consistent output throughout  the roller life 
• Reduction in downtime (2 hours per machine) 
• Working life of rubber roller (5000 h) is three times that of leather roller (1500 h)
• Energy consumption is less by 15%. 
• Periodical grooving and drudgery involved in grooving operation is eliminated 
• Eco-friendly roller with no chromium contamination
• No environmental pollution and health hazard to workers. 

Cost : Rs  25,000 per roller
