摘要： A process for preparing a high density detergent-composition is provided. The process comprises the steps of:a) drying detergent agglomerates to a free moisture content of less than about 7% by weight thereby forming substantially dry detergent agglomerates; andb) charging the substantially dry detergent agglomerates into a moderate speed mixer/densifier to densify the substantially dry detergent agglomerates to form a high density detergent having a density of at least about 900 g/l. In preferred embodiments, the process also comprises forming hydrated detergent agglomerates via the steps of hydrating an anhydrous hydratable detergent salt to a degree of hydration of at least about 60% and agglomerating the hydrated detergent salt by charging the hydrated detergent salt and additional detergent ingredients into a high speed mixer/densifier and agglomerating the hydrated detergent salt and additional detergent ingredients to form hydrated detergent agglomerates.
