Challenge: 

Extension of the operating time of V-belts
for the drive of a specific stone crusher . 

 

Problem/ Requirements  :

So far, the standard V-belts or kraftbands
had to be replaced regularly. 

 

Solution : 

After the changeover to the maintenance-free Optibelt RED POWER II
high performance V-belts, these problems are a thing of the past.
Four Optibelt RED POWER II S=C PLUS V-belts in SPC profile with
a length of 5000 mm were chosen and installed.
 
 

Effects : 

The maintenance-free Optibelt RED POWER II V-belt has been in operation
for over 17 months at 60 hours per week now – without any trouble.

Savings  :

Before and after the installation the energy consumption was measured
with a Fluke multimeter in order to determine the energy savings. In the
calculation, a continuous load is assumed and estimated for a period of
3000 operating hours and a kilowatt hour rate of US$ 0.1428.

- Conveyor system no. 1 : 1.2 % savings realised = US$ 185.66 per year
- mill no. 1 : 1.4 % savings realised = US$ 376.07 per year
- Mansfield macerator no. 4: 5.2 % savings realised = US$ 2,892.15 per year .
