On Hein - Lehmanni Continuous Centrifugal

For a number of years the cane sugar industry has been experimenting with various types of continuous centrifugals. The obvious advantages of lower power, less labour and uniform performance make this type of operation very attractive. At our 1954 and 1955 Congresses two very interesting papers were read dealing with the performance of the pusher-type of continuous centrifugal developed by the Escher Wyss Company of Switzerland. The Hein-Lehmann continuous centrifugal is another type which has been tested by a number of sugar mills in Natal. during the 1956 season. Although results were not up to the standard required of A and B sugars, the machine is nevertheless very interesting owing to its simplicity of construction and ease of operation and may find industrial application in other operations such as fore-curers of C massecuites or in the refinery affination process.
