Two divisions. One standard of execution.
Norritrade runs two independent operations. Our milling division breaks down and refines hardened salt cake and other industrial minerals for the local market. Our SLS division exports Sodium Lignosulphonate to concrete, mining, agriculture and dust-suppression customers around the world.
Capability
Everything between the raw block and the sealed bag
Industrial milling
Hardened salt cake broken down and reduced on high-throughput mills built for abrasive, set-solid feedstock.
Precision refining
Tight control of moisture, hardness and particle shape so every tonne behaves the same in your process.
Screening & classification
Multi-deck screening and air classification deliver accurate, repeatable cuts to your grade specification.
Mechanised handling
Fully mechanised intake, conveying and silo storage, keeping product dry, contained and traceable.
Automated bagging
Automated bagging and palletising into bulk bags or 25 kg units, sealed, weighed and labelled for local dispatch.
SLS export logistics
A separate division manages SLS container packing, documentation and worldwide shipping from South Africa.

SLS Division
Sodium Lignosulphonate, on spec and on the water
A brown, water-soluble powder derived from the neutral sulphite semi-chemical pulping of eucalyptus and pine, CAS 8061-51-6. Consistent pH, high total solids and minimal water-insoluble material make it a dependable dust suppressant, briquetting binder, fertiliser granulation aid and concrete plasticiser.
