Dynamic Inline Mixer

Dynamic mixing with Pin mixing elements
for shear sensitive products

The INDAG Dynamic Inline Mixer type DLM/P is used for homogeneous mixing of shear sensitive liquids with additives. Additives can be homogeneously mixed in the smallest quantity ratios of less than 0.01%. Also, due to the shape of the mixing elements, the heat input into the product stream is reduced to a minimum. Temperature increases of less than 1°C can thus be kept to a minimum. Temperature-sensitive products can be mixed homogenously in a gentle manner. Some examples from a range of applications are: The mixing of reactive additives with adhesives; the dilution of polymer emulsions; the mixing of polymers with hot water or steam, e.g. for the separation of solvents.


Advantages of DLM/P

  • Very good self-cleaning during CIP-cleaning
  • No pressure loss
  • Very good homogeneous mixing result even when mixing in smallest quantities (0.01 %)
  • Efficient introduction of mixing energy
  • Variable mixing energy by speed change via frequency converter 
  • Temperature increase less than 1 °C
  • Applicable at high pressures and high temperatures

Technology of DLM/P

INDAG Dynamic Inline Mixer type DLM/P consists of round shape mixing elements on rotor and in stator (mixer casing). Round shape mixing elements are extremely robust to allow mixing of highly viscous products (> 10,000,000 mPas). Mixing energy is introduced efficiently into product. It is possible (as an option) to heat or cool rotor and stator. The DLM/P is offered in compact design (KB) and in bearing block design (LB). In the compact design, the rotor is mounted  by the output shaft of the motor. In the bearing block design, the rotor is mounted by its own bearing block. With a separate bearing block, longer rotors and thus larger mixing volumes can be realized. Furthermore, this design is also suitable for mixing under high pressure or high temperature. The type of rotor seal is selected to suit each application. For the supply of the double acting mechanical seal INDAG offers the suitable barrier fluid system. INDAG mixers are designed likewise for explosive areas and substances (ATEX).
