Table: Size and quantity of ESL for the absorption of the occurring kinetic energy
At the transfer stations of large belt conveyor systems for the
pit and quarry industries, some belt damages may occur on
the next downstream conveyor generated by the high impact
force of falling sharp-edged mineral lumps. Furthermore, the
continuously undamped material impacts of sharp and abra-
sive mineral lumps cause a high material wear on the very
expensive belts, shortening considerably their lifetime.
Transfer or impact stations equipped with ROSTA anti-vibra-
tion mounts type ESL offer an effective absorption of the occur-
ring kinetic energy of falling lumps with their progressive
deflection characteristics. The belt surface is protected from
scissures and high abrasion wear.
Please ask for our
specific information manual “Impact Beds” and
“Elastic Garland Suspensions”.
