The Scraper Bottom Discharge Centrifuge is specifically designed for the solid-liquid separation of carbonate precipitates generated during chemical reaction, crystallization, and purification processes. It is widely used in lithium carbonate production, calcium carbonate manufacturing, sodium carbonate recovery, magnesium carbonate processing, and various inorganic salt precipitation systems.
The centrifuge automatically completes feeding, filtration, cake washing, dewatering, scraping, and discharge within a controlled operating cycle. It is particularly suitable for carbonate slurries with high solids concentration, large crystal volume, and strict product purity requirements.
Compared with conventional filtration systems, the scraper discharge design provides higher production efficiency, lower labor requirements, improved crystal recovery, and more consistent product quality.
Carbonate precipitation processes generate large quantities of fine or medium-sized crystals that must be separated efficiently from reaction liquor.
Common challenges include:
The Scraper Bottom Discharge Centrifuge provides efficient solid-liquid separation and reliable crystal recovery while maintaining stable product quality and production throughput.
Peony provides not only centrifuge equipment but also complete carbonate separation support.
Our engineers evaluate:
We help customers select:
The carbonate slurry enters the rotating basket lined with filter media.
Under centrifugal force:
The entire process is automatically controlled through PLC operation, ensuring stable and repeatable separation performance.

The centrifuge efficiently captures precipitated carbonate crystals and minimizes product loss in the mother liquor.
Effective filtration reduces liquid retention inside the cake, helping improve downstream drying efficiency and product purity.
Large basket volume and automatic discharge allow continuous handling of high precipitation rates from industrial reactors.
Optional cake washing removes soluble impurities and improves final carbonate purity.
Designed for long production campaigns with minimal operator intervention.
The scraper mechanism automatically removes crystal cake and prepares the basket for the next cycle.
Available in SS304, SS316L, Duplex Stainless Steel, Titanium, and other corrosion-resistant materials depending on process chemistry.
To recommend a suitable centrifuge solution, please provide:
Carbonate precipitation typically produces filterable crystal solids that require efficient recovery and washing. The scraper centrifuge combines high separation efficiency with automatic cake discharge, making it suitable for industrial carbonate production.
Yes. Integrated cake washing systems can remove residual mother liquor and dissolved impurities, significantly improving final product purity.
Yes. Scraper bottom discharge centrifuges are commonly used in lithium carbonate crystallization and precipitation processes where crystal recovery and purity are critical.
Yes. Filter media and basket configurations can be customized according to crystal size distribution and filtration characteristics.
Yes. The centrifuge can be integrated with reactors, crystallizers, thickening systems, dryers, and packaging equipment as part of a complete carbonate production line.
Peony welcomes distributors, agents, EPC contractors, engineering companies, and industrial partners involved in lithium refining, carbonate production, crystallization systems, inorganic salt manufacturing, and solid-liquid separation projects.
We provide equipment selection support, process consultation, application engineering, spare parts supply, technical training, commissioning service, and after-sales support to help partners expand their local markets.
Send us your carbonate type, crystal characteristics, production capacity, moisture target, and process requirements. Our engineering team will recommend the most suitable centrifuge solution for your project.
