Emerging Grinding Technologies

There are emerging grinding technologies such as ultrasonic comminution and plasma comminution. Ultrasonic comminution transfers the energy needed for crushing to the material by acoustic pulses. This approach was introduced in 2003. Two counter-rotating disks with special aerodynamic surfaces generate ultrasonic pulses, which due to their small pulse duration exert pressure waves on the particles which are pulverized very efficiently. The results from first tests with granulated blast furnace slag of different origins were promising, but future research remains necessary. The scaling up to industrial dimensions in particular is an open question. The system has been tested for slag grinding in model scale only. Plasma comminution is performed in a liquid by using shock waves. The application is tested on semiconductor materials.
