The plansifter is the single most expensive item in a modern mill. A typical top quality 6 section plansifter costs more than a double high rollermill. We have installed over 30 Miag LM series plansifters in South Africa. On average these machines are 34 years old and older. The last MIAG plansifters were manufactured in 1976.
The process of reconditioning involves the following:
1. Strip all wood corners and stock flow diverters from machine
2. Replace all back and side panels that are badly dented or damaged
3. Fit new single or double inlet plates on top as required for new diagram
4. Sandblast the machine and spray paint with the highest quality Speiss Hecker paints.
5. Return machine to the plansifter cabinet workshop for refitting and felting of cabinets
6. Fit all new sieve groups with new flow diagram
7. Fit all required flow diverters dust blank-off
8. Fit new bearings to the drive station
9. Spray paint all inlet and outlet tables and spouting and end covers
10. Sandblast main transverse suspension beams and spray
11. Supply all new reed canes and sock connections for inlet and outlet spouting
Reconditioned plansifters, which are fitted with all new sieves and in accordance with the method mentioned above, cost about 50 % of the cost of a new plansifter from market leader manufacturers. (Ex-workshop Alrode Johannesburg)
Depending on the flow diagram and the capacity on the section which influences the sieve box heights, a typical six section plansifter with 2150 mm cabinet height and 25 sieves per cabinet, can generate 40 m² nett sieving surface.
With proper maintenance, a Shamrock Milling reconditioned plansifter could deliver another 20 years service and more.
