RULMECA - MELCO SUPREME

Heavy Duty Corrosion and Abrasion Resistant Roller

Following the acquisition of Melco Company, South Africa at the end of 2006, the Rulmeca Group is proposing the roller SUPREME, heavy Duty Corrosion and Abrasion Resistant Roller

The Melco SUPREME boasts a wide range of superior advantages, features & benefits:

• Steel tube ensures adequate mechanical strength for heavy duty loads

• Ultra thick abrasion and corrosion resistant 12mm thick HDPE sleeve

• HDPE contains carbon black increasing ultra violet resistance

• Steel and HDPE tube combination provides significantly reduced weight

• The bearing housing effectively locks the HDPE tube in position preventing movement along the steel tube

• Minimum “C dimension” decreases load induced shaft deflection

• Unique large diameter stoneguard with integral labyrinth design minimises possibility of being jammed by spilt material, and provides additional protection from water and dust

• Multi part labyrinth seal protects the bearing from ingress of contaminants

• Ultra low running resistance and break away mass reduces power consumption for start up and continuous operation

• Machined fi nish ensures LOW run-out, minimizing vibration and noise emission

• Castellated HDPE tube is a tight interference fit on the steel tube

Typical applications are mining, coal process plants, coal fired power stations, import/export terminals, belt scales , aluminium smelters, steel plants, fertilizer plants.

How do you prevent this design from being power hungry?

Having two viscoelastic bodies deforming at the belt-to-idler interface will likely consume significantly higher power than a simple steel shell idler roll.

Designers beware. Maybe the mfg. can give some detail on the 12 mm thick idler rubber covering.

My guess is this will almost double the rubber indention power.

Hope I am wrong.
