Supply of powdered quicklime
Cement tanker truck
Lime is fed from the silo to the loading unit and pneumatically conveyed into the cement tanker truck. It is transported in bulk in a sealed pneumatic tank, which prevents contact with moisture and ensures safe transportation.
Tarpaulin-covered semi-trailers (Euro trucks)
Delivery is carried out in big-bags (MBR) of 900–1000 kg with an internal polyethylene liner that protects the product from moisture and CO₂. Transportation is performed using flatbed or tarpaulin-covered semi-trailers.
