    Wet Grinding, also known as wet milling, is a process of taking materials in a liquid form or slurry and reducing particles, such as agglomerates, by breaking them apart or shearing them down in size. Since the early 1800’s companies have manufactured machines that were engineered to process wet materials. As time went on people formulated

    Ultrasonication is an efficient means for the wet-milling and micro-grinding of particles. Besides dispersing and deagglomerating, the wet milling is an important application of Hielscher ultrasonic devices.. In particular for the manufacturing of superfine-size slurries, ultrasound has many advantages, when compared with common size reduction equipment, such as: colloid mills (e.g. ball mills
