Salt agglomeration

Process

The process consists in briquetting or compacting granulating under pressure sodium chloride into briquette or granules. Generally, salt is agglomerated after the drying step which reduces the moisture to less than 0, 2%. A force feeder or a gravity feeder feeds the salt between two rotating parallel rollers turning in opposite directions. This process allows the formation of briquettes or flakes. Depending on the need, the flakes can be crushed into granules and screened to the required final size ranges (2-5/ 3-6 mm etc…). The quality of salt determines the compression roller speed and the pressure level. Additionally, the size range has a great influence on the choice of feeding systems in presses (gravity or force feeder).

Advantages

• A large choice of briquetting press capacities (from 300kg/h to 10 MTPH or more…) and design (different briquette shapes, different feeding systems etc...)
• A proven process: many references of such plants in operation worldwide on solar evaporation salt, refined and raw mine salts.
• The capability to test the different salts in our pilot plant.

Proposed Services

• Audit of existing units.
• Applied R&D in pilot plant.
• Engineering process.
• Manufacturing of compactors and granulators.
• Integration of complementary equipment (dryer, crusher, mixer…).
• Maintenance and associated on-site services.
