Trouble shooting 4.2/3-1
PROBLEM CAUSE ACTION
Separation capacity
(solids-/centrate quality light
and heavy phase)
not
sufficient
Capacity exceeded
(too high solids load, too high
fine grain portion, too high
liquid quantity)
Reduce throughput, adjust operating
parameters new;
Check type / dosage of additives
(if existent)
Change of product Readjust operating parameters
Change of additives
(flocculant)
Check type / dosage of additives
(if existent)
Part of light phase
contained in heavy phase
is too high The diameter, on which the
separating line between
light and heavy phase is, is
too big
1
Reduce paring diameter
Separating line unclear Increase speed
Heavily fluctuating feed
conditions (quantity,
concentration, …) Check system, create constant
conditions
Part of heavy phase
contained in light phase is
too high The diameter, on which the
separating line between
light and heavy phase is, is
too small
1
Increase paring diameter
Separating line unclear Increase speed
Heavily fluctuating feed
conditions (quantity,
concentration, …) Check system, create constant
conditions
Part of solids contained in
light phase is too high Clarification not sufficient;
operating parameters are
not optimally set
1
Increase bowl speed
Increase differential speed
Mount phase separation disc with
smaller inner diameter
Increase dosage of additives,
respectively check effectiveness
Heavily fluctuating feed
conditions (quantity,
concentration, …) Check system, create constant
conditions
Part of solids contained in
heavy phase is too high Clarification not sufficient;
operating parameters are
not optimally set
1
Increase bowl speed
Increase differential speed
Increase dosage of additives,
respectively check effectiveness
Heavily fluctuating feed
conditions (quantity,
concentration, …) Check system, create constant
conditions
1
unless the centrifuge has already reached its performance limits
