Low Moisture Pusher Centrifuge for Salt Dewatering

Pusher Centrifuge for Refined Salt and Vacuum Salt Dewatering is designed for continuous dewatering of refined salt crystals, vacuum salt crystals, and salt slurry in industrial salt production lines.

In refined salt and vacuu m salt processing, salt crystals often carry brine, mother liquor, or wash water after washing, crystallization, or slurry discharge.

A pusher centrifuge removes free liquid from the salt cake through centrifugal filtration and continuously discharges dewatered salt before drying, screening, or packaging.

• Refined salt dewatering
• Vacuum salt dewatering
• PDV salt crystal dewatering
• Washed salt dewatering
• Salt slurry solid-liquid separation
• Brine separation from salt crystals
• Mother liquor separation after salt crystallization
• Salt cake washing and dewatering
• Salt dewatering before fluidized bed drying
• Salt processing line integration

The actual result depends on salt crystal size, slurry concentration, brine viscosity, screen opening, washing requirement, and operating parameters.

Salt production lines require stable and continuous removal of liquid from salt crystals. If dewatering is not effective, the plant may face:

• High moisture before drying
• Higher dryer energy consumption
• More brine carryover
• Unstable dryer feeding
• Salt caking or uneven drying
• Lower product purity after crystallization or washing
• More load on screening and packaging sections
• Higher operating cost in continuous salt production

A pusher centrifuge helps remove free brine or mother liquor from salt crystals continuously. When product washing is required, washing liquid can be sprayed onto the salt cake during cake transport.

The machine supports continuous feeding, filtration, washing, dewatering, and discharge in salt production lines.

By removing free brine or wash water before drying, the centrifuge helps reduce downstream drying pressure and energy demand.

The pusher mechanism continuously moves the salt cake forward, helping maintain stable discharge and dryer feeding.

Washing nozzles can be added to reduce residual mother liquor or soluble impurities when product quality requires it.

The centrifuge can be configured for washed refined salt, vacuum salt, PDV salt, and crystallizer discharge salt slurry.

Separated brine or mother liquor can be collected for reuse, return to process, or further treatment depending on the plant design.

Under suitable feed and operating conditions, the system can typically help achieve:

• Continuous separation of salt crystals from brine or mother liquor
• Lower free liquid carryover before drying
• More stable salt cake feeding to the dryer
• Reduced dryer load compared with direct wet salt feeding
• Better control of residual mother liquor through optional cake washing
• Stable operation for continuous salt production lines
• 8–24 hours/day operation depending on plant design and cleaning frequency

For many salt washing or salt processing lines, centrifuge dewatering is commonly used before final drying. Final cake moisture depends on salt type, crystal size, slurry concentration, screen opening, centrifugal force, washing condition, and operating parameters.

To recommend a suitable pusher centrifuge for salt dewatering, please provide:

• Salt type: refined salt, vacuum salt, PDV salt, washed salt, or other salt
• Processing capacity
• Feed slurry concentration
• Salt crystal size distribution
• Crystal shape
• Brine or mother liquor composition
• Feed temperature
• Target cake moisture
• Product washing requirement
• Required product purity
• Filtrate reuse or collection requirement
• Corrosion condition
• Upstream process: washing line or crystallizer
• Downstream process: dryer, cooler, screening, or packaging
• Required operating hours per day
• Site voltage and control preference
• Preferred material of construction
• Required screen slot size, if known
