Abrasion resistant belt

1 Introduction

Rexline Engineering had supplied Group with Abrasion Resistant Fabric Conveyor Belts in August 2018.
This belt was supplied to Nifty Copper Mine which is an operating underground copper sulphide mine with an associated 2.5Mtpa copper concentrator. Processing of sulphide copper ore is by conventional comminution, grinding and flotation to produce a clean copper concentrate.The copper concentrate is trucked to a storage facility located at Port Hedland, approximately 350km from Nifty, where concentrate is accumulated before shipping for smelting and refining.

3 Project Benefits Review

PARAMETER	BENEFITS
SERVICE LIFE	The belt is currently in operation since it has been installed in September2018.Expected Service Life: 12 Months
COST	Replacement and Maintenance costs of these belts was reduced by 15% considering for a year’s worth of service life.
