Bauer Separator Compact

 

 

 

 

 

 

 

For example, Fig. 13-15, right and middle images, shows plating that has been worn down on the outer 
edges of the auger, but recoating is still possible because the plating on the face side is still retained 
up to 20%, meaning that the actual auger blade has not yet been damaged. Excluding the plating, the 
auger blades have a thickness in this area of 10 mm, meaning that the remaining plating can be de-
termined very precisely with a depth caliper. 
 
The left image in Fig. 13-15 shows a auger on which the axial plating has been worn down completely 
on the outer edges of the auger blade. In addition, the auger thickness itself has been reduced almost 
to half. A cost-effective recoating is not possible in this case since the base stiffness of the auger blade 
would no longer suffice for sufficient bonding of the plating. A new auger is therefore required. 

 

 
 
 
 
 
 
 
 
 

 

 
 

13.6  SUMMARY OF MAINTENANCE AND INSPECTION INTERVALS 

 

 

Check the operational safety of the machine before every start ! 

 

Daily:   

  Visual inspection of the solid cake and the effluent

 

  Visual  inspection  of  the  machine  and  gearbox  seals  (see  section 

13.1.1 Fig. 13-3 Gearbox inspection opening)

 

 

Every 250 operating hours (or every 2 weeks):  

  Supply with sealing medium (see section 13.1.1)

 

 

 
Every 1-3 months  

  Inspection and cleaning of the housing, screen, guide rails,  

plastic profile rails, auger, housing protection ring  
(see section 13.2 - 13.5) 

  Readjust scraping bolts (see section 13.3 Fig. 13-13) 

 

Every 6 months: 

  Check gearbox oil level 

 
After 10,000 operating hours (no later than every 2 years) 

  Geared motor oil change (see the gearbox and motor documentation for 

oil quantity and type) 

  Inspect the bearing (see the gearbox and motor documentation for de-

tails)
