Java Method Mill Setting Adapted and recreated by Toät Soemohandojo

There is a mill settings system called the “Java Method”, which was created based on the theory by the Dutch scientists such as Muller von Czernicky and Gogelijn since before 1900.

They were researchers at the famous research centre named “Proefstation Oost Java” (POJ), which is now renamed as Indonesian Sugar Research Centre in Pasuruan, East Java – Indonesia.

POJ was one of the main reference for the world’s sugar industries, among other things the Java Method mill setting calculations, which taken and used as preference system by many countries such as Australia, Mauritius, South Africa, Philippine, Hawaii, India, Pakistan and the other countries in South America as well.

The Java Method has the philosophy that the sugar juice contained in cane must be extracted as much as possible by the milling with a minimum dissipation. To get such extraction the mill crushing only the fibre contained in cane and must be within as slow as possible roller rotations.

This was possible at the time when reciprocating steam engines in use for the drives and the roller rotations were between 2.5 – 1.2 rpm only, decreases from the ultimate to the following mills.

There are 2 (two) subjects of Java Method approaches in this paper:

• The Mill Settings
• The Design Capacity
