Unloading mineral fertilisers from wagons
Ammonium nitrate, NPK, potash and urea cake even when treated with anti-caking agents. The VH-500 discharges caked fertilisers in minutes — no crews with sledgehammers.
Why fertilisers cake
Practically every type of bulk mineral fertiliser — ammonium nitrate, NPK, potash, urea — is prone to caking, even when treated with special agents. Hygroscopic fertilisers especially: the longer the cargo travels in a wagon, the damper it gets, and in winter that moisture freezes slightly — the cargo becomes hard to discharge.
Extreme case: urea
Damp urea left standing in wagons: up to 10 hours of hard manual work per wagon (in that exceptional case it was broken up with rods through the hatches) → about 30 minutes with the VH-500.
An ordinary day
Typical wagon: 15–20 minutes of manual unloading → up to 5 minutes including clean-up. The equipment can work down to −40 °C (with special oil and dried air).
