Reaction is a chemical procedure where one or several chemical compounds or elements are transformed into other chemical compounds.

Usually reactions are connected with changes in the chemical bonding of the molecules or crystals. Physical procedures where only the aggregate state changes, such as evaporation or melting, the mixing of pure substances into alloys, diffusion and atomic reactions are not included as chemical reactions.

Besides the substances that are to be chemically bonded, chemistry usually also requires the appropriate surrounding conditions. Here, the addition or removal of heat, the regulation of different pressures and the deliberate mixing of individual components are of great significance.

DVA offers the appropriate process apparatus such as bucket dryers, cone dryers, agitators and mixers for the widest variety of reaction processes.

Whether crystallisation, calcination or agglomeration, mixing or transformation, many process can be carried out in DVA apparatus.
