The IKA MHD 2000 (mixing-homogenizing-dispersing) system is designed for mixing solids (powders, granulates) with liquids. It is predominantly used for fully continuous production processes. The MHD unit is particularly suitable for applications which meet at least one of the following criteria:
- The process should largely occur in a single pass.
- Up to 80% solid concentrations are to be incorporated in a single pass.
- A reaction occurs immediately after mixing.
- The liquid phase is already highly viscous.
- The amount of energy required for the mixing process is to be minimized.
- The solid is a granulate and is to be crushed mechanically as well as mixed.
- The amount of entrapped air is to be minimized.
This unique wetting method was developed to minimize air entrapment, which can occur in solid/liquid dispersion systems based on the Venturi principle.
Throughput of the MHD is set by adjusting the dosage system. The amount of energy required, and thus the degree of mixing, is determined by the speed and the tool configuration chosen. For simple processes such as filling tanks or storage containers, volumetric dosage systems are generally adequate. In the case of fully continuous processes requiring high levels of precision, quantity controlled dosage pumps are used for the liquids and differential dosage scales for the solids. The results are generally accurate to within 0.5% or better.
The MHD 2000 mixing system is available in seven different sizes with throughput volumes of between 60 and 40,000 l/h. All sizes operate at the same rotor peripheral speed, thus ensuring the most reliable conditions for scale-up.
