Over the years Maguin has installed more than 100 drum prewashers or main washers in various configurations for all types of feeding and for capacities from 2,500 to 48,000 t/d per unit.

The Maguin drum washer is the perfect washing or prewashing solution in terms of running capacity, washing efficiency, sugar losses and maintenance. It is suitable for warm countries (Egypt, Morocco) and cold countries (Russia, USA), for heavy soils, clay : France, Netherlands, Belgium etc, tchernozium (Russia)) as well as light soils, silt or sandy soils (Poland, Germany, England etc). The drum technology has largely outperformed the old technology of the paddle washer that Maguin can nevertheless supply on specific request. The friction drive and the construction in thick steel plate ensures operation with minimal intervention for more than 10 years.

The range of drums is wide and suits all types of feeding (see attached schemes) :

The drum size and type are selected according to the tare to be treated, the climatic conditions and the beet output.

• short drum prewasher for light tare and dry feeding
• drum with prewashing compartment or with elongated washing compartment for high tare and/or cold countries and dry feeding
• drum with water separating compartment or separating wheel for wet feeding

The technology of the drum washer with dry feeding results in a concentrated washing water at the outlet and limits the size of equipment downstream (ratio washing water / beet output < 1). A clarifier is then not absolutely necessary.
