| Applications |
| |
| The Vertical Basket Centrifuges operate under a discontinuous filtration process and are well suited to the efficient separation of Pharmaceutical products and of fine or bulk chemicals. Used where small batch sizes and where products are changed frequently with low process costs, i.e. one machine for many products. No crystal breakage, as the peeling is done at reduced speed. They can handle freely and non freely filtering slurries with equal facility. |
| |
| Typical Products |
| |
| Atrazine, vegetable extracts, quinine Sulphate, hydrazine, antibiotics, citric acid, pentaerythritol, etc. |
| |
| Applications |
| |
| Amino acids, benzoic acid, benzene, hexachloride, calcium hypo chloride hexachlorocyclohexane insulin, potassium bisulphate, sodium perborate, penicillin, sulphur, starch, etc. |
| |
| Working Principle |
| |
- Batch operation
- Variable speeds for filling, spinning, washing and scraping
- Feed controlled by filling valve through feed pipe or distribution funnel
- Filling by gravity or pump or by rotating cone to affect gentle acceleration of suspension.
- Basket filling monitored by filling level controller
- Intensive cake washing with one or more fluids after spinning
- Separation of mother liquor from wash liquor by valves
- Cake discharge.
Options :
Bottom Discharge :
Paring knife removes the cake towards the open cents.
Top discharge:
- Manual:After filtration removal of cake by manual scraping & shovel
- Bag Lifting:Entire bag lifted by upper ring to which the filter bag is attached.
