Financing calculation BritAS in comparison with Conventional Screen Changer or Backflushing system

Please enter your data in the red framed spaces. The program calculates automatically.

Actual

 BritAS

Calculation only compatible with
Microsoft Internet Explorer

Please enter here the actual average output of your extruder in kg/hour.Actual extruder output kg/h   

 

   

Please enter here the maximum output of the extruder indicated by the manufacturer. This throughput can probably be reached with a Britas screen changer.Maximum extruder output in kg/h   

 

2 shift = aprox. 4300 hours/year -- 3 shift = aprox. 5800 hours/year -- 4 shift = aprox. 7000 hours/year -- 5 shift = aprox. 8300 hours/yearIn how many shifts do you operate in your company?   

 

    

e.g. electricity, personnel, rental, deduction, but without raw material purchase. Servs for the calculation of melt loss.Estimated production costs / kg, e.g. 0,30   

 

    

    

What is the average material purchase price?Material purchase price, e.g. 0,15   

 

    

    

 e.g. with a 2 piston screen changer melt flows through both screens simultaneously.Number of simultaneously working screens  

 

    

    

Please enter here diameter of the screen in mm.Screen diameter in mm   

 

Please enter here costs for one screen plate or screen package.Costs for a complete screen change   

 

    

After how many minutes do you have to change the screens when processing highly contaminated material..After how many minutes do you change the screens   

 

After how many minutes do you have to change the screens when processing highly contaminated material..Loss of material in percent (only for Backflush!!)  

 

e.g. with a 4 min. change frequency personnel is engaged approx. 60% of the time with screen changing.Personnel need in percent   

 

    

e.g. 1.700 EUR/month x 12 months x 1,7 = 34.680 EUR (multiplied with factor 1,7 are wage side-costs like: social contributions, vacation, illness, etc.).Cost per year for one person incl. all wage side-costs

     = Advantage per month after deduction of the leasing fee (estimated)

 

* For the calculation of the advantage resulting of production increase we assumed that production  costs of this increase  only represent 50% of the total production costs, since fix costs like rental, salaries, etc. remain unchanged. Only the  variable costs like electricity, water, etc., incure  additionally. No profit has been considered herein.
