BV-VT with EP carcass


Type and specification of Dunlop belt supplied
BV-VT with EP carcass (various types and widths)
Current operating life of Dunlop belt:
Between 2 and 7 years. 2 years under the most severe conditions, up to 7 years for the more moderate conditions
Average life of competitor’s belt – months
Some less than one year, others 2 or 3 years. Generally about half the lifetime of Dunlop BV-VT

Hot sulphur is pelletized from molten sulphur and the pellets come out from the pelletizing units in a wet condition. The water contains medium/low concentrations of sulphuric and sulphurous acid. Because BV-VT EP belting is chemically resistant and sufficiently heat resistant under these conditions, it is providing a very good operational lifetime. BV-VT also has good oil resistant and anti-static properties and complies with the required ISO 340 and/or MSHA flame retardant standards. BV-VT is also sulphur resistant. Sulphur is used for many rubber types as an accelerator in the vulcanising of rubber. Normal belts will become hard and start to crack after a short while under these conditions. When the belting is cracked, there are problems with carry-back and carcass deterioration through penetrating acid. Splice failures can also occur. BV-VT will also crack (but only under the most severe conditions) as the process is much slower than with ordinary belts. Under more moderate conditions, down-stream in the material handling process and for stacking/reclaiming and ship-loading, there is no significant cracking in BV-VT and the belting is simply being replaced, either when there is mechanical damage or when the belting is worn out.
