Applications And Markets
Applications
HEINKEL TiClassifying centrifuges are used in quasi-continuous wet classifying processes where fine, ultra fine and nano-scale particles have to be classifyied within a slurry.The most common applications are separation of TiO2, SIC, Zr, Al2O3, CaCO2, Kaolin which is suspended in either water or ethylene glycole
Markets
- Applicatios with TiO2
- Application in Nano- technology

Step 1: Acceleration to Feeding Speed
The solid-bowl is accelerated to approx.2,000 – 2,500 rpm
Step 2: Feeding
The unclassified slurry is introduced into the bowl through feed pipe and feed cone system
Process Steps
Step 3: Classifying
-Depending on the feed flow rate the sizeof the classified particles can vary.-Coarse particles remain in the solid-bowlwhile the classified fines are removed viaskimming tube-The clasifiying time is ~1-3 hours
Step 4: Discharge
Once solid-bowl is filled with sediment to ~70% the discharge commences
The bowl rpm is reduced to 400 – 500 rpm
The sediment is discharged with the plough with Ethylene Glycol or water as an aid
The resdispersed sediment is discharged through openings in solid-bowl bottom
Process Steps (cont.)
Step 5: Rinsing
Once plough reaches preset end position, the rinsing process is started
The basket is decelerated to standstill. During this time the basket is rinsed with EG or water.

Customer‘s benefit
The process-related advantages of this Centrifuge are:
Precise cut-off of the classified particles no intermixing of classified particles with the slurry coarse particles may be recycled in a ball mill the suspension is of high quality=>equal distribution of ultra fine particles minimal downtime during production. The centrifuge capable of handling different flow rates
User Advantages of the Tiocent classifying centrifuge:
easy installation of system due to pre-assembled piping and wiring of centrifuge, due to years of experience HEINKEL can also calculate and offer peripheral
components. The cut-point of the classified particles can be easily adjusted. Fully automatic, with low vibration and highly reliability Easily integrated into a plant-wide process control system.
