A typical process cycle for a batch filtering centrifuge comprises the following 7 steps :
    
    
1) '''Accelerate to feed speed''': The basket is accelerated to a speed suitable for feeding.
# '''Accelerate to feed speed''': The basket is accelerated to a speed suitable for feeding.


2) '''Feeding''': The feed solid - liquid suspension is added to the basket via feed pipe.  
# '''Feeding''': The feed solid - liquid suspension is added to the basket via feed pipe.  
   
   
3) '''Accelerate to spin speed''': Accelerate the basket to a high rpm to produce a high ‘G’ to drive the filtration process.
# '''Accelerate to spin speed''': Accelerate the basket to a high rpm to produce a high ‘G’ to drive the filtration process.


4) '''Washing''': If required the filter cake is washed via wash pipe.  
# '''Washing''': If required the filter cake is washed via wash pipe.  


5) '''Drying''': Continue spinning at high ‘G’ to dry the filter cake. The filtrate leaves via outlet.
