MHD Plant

The IKA mixing plant MHD essentially consists of the patented IKA inline mixing machine MHD, metering units, an electrical control system and a periphery which is customized to fit the customer's application. The MHD plant enables the dust-free mixing of liquids and solids (powders or granules) in a continuous process. The phases to be mixed are fed into the MHD machine in proportion to quantity, then mixed in the working chamber and subsequently dispersed, allowing for a ready final product to be produced in just one passage.

The plant is able to process solids contents of up to 80% and mixtures with viscosities of up to 50,000 mPa?s. The funds invested into dosing are considerably lower than the purchasing costs for holding tanks and the appropriate mixing vessels with stirrers. Furthermore, the MHD plant offers great flexibility as any product quantities can be produced with a constant quality.

As for electric control of the plant, different versions are available, depending on customer demands:

Manual control: Essential, safety-relevant locking devices are put into effect. Flow rate is controlled via simple potentiometers.

Automatic control: The control system allows for a defined sequence to be run in automatic mode. After starting, the plant runs automatically until it is shut down either manually, by means of an external signal or due to a breakdown.

Recipe management: Recipes can be compiled, changed and archived by means of a process control system.

The IKA MHD mixing plants are manufactured in seven different sizes ranging from lab and pilot plants to production plants with an overall throughput of 40,000 l/h. The supply scope of the MHD plant conforms to your inquiry. Devices for powder feeding such as sack emptying machines and big bag stations, systems for conveying of the final mixture, buffer vessels, IKA machines for fine milling and other peripheries can all be installed into the production line. Per request, our services can also include the on-site assembly of the plant, commissioning and training for your personnel. Getting the whole system from one source will allow for you to have just one contact person for your entire project.

Advantages of the MHD plant:

Considerable reduction of production times

Simple and safe handling

Compact design; only small feeding vessels necessary

Fully continuous mode of operation which also allows for flexibility during the production of the desired product quantities (no dependence on minimal/maximum batch sizes)

Same system for the plants on the lab scale and production plants of all throughput capabilities

Proven and tested type series

Closed systems, thus prevention of dust and solvent emissions

Prevention of agglomerate formation thanks to particle-to-particle wetting

No loss of raw materials due to bundle handling

Entries of solid concentrations up to 80% and production of the final product in just one passage possible

Highly precise mixing results with proportioned addition of raw materials

Flexible tool configuration and speed regulation for optimal adaptation to product

Finest particle sizes thanks to wet milling in the dispersing stage

Suitable for very viscous products into the pasty area

Ideal for reactive processes and for quick viscosity increases due to short residence times

Fully automatable

Applications

The IKA MHD plants are suitable for a broad range of applications, particularly in the chemical, cosmetic, pharmaceutical and food industries. The following can be processed as liquid phases, among others: Water, oils, resin, kerosene, alcohols, liquid polymers, low to highly-viscous dispersions, molten urea, syrup and solvents.
