DLM/P Dynamic Inline Mixer
Dynamic mixing with Pin mixing elements
for shear sensitive products
The INDAG Dynamic Inline Mixer Type DLM/P is used, among other things, for the homogeneous mixing of shear-sensitive liquids with additives. Additives can be mixed homogeneously in very small quantities of less than 0.01%. The shape of the mixing elements also reduces heat input into the product stream to a minimum. This means that temperature increases can be kept below 1°C. Temperature-sensitive products can thus be mixed gently and homogeneously. Alternatively, the parameters can also be selected so that heat is actively introduced into the product.
Advantages of DLM/P
- 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
- Very good self-cleaning during CIP-cleaning
Application examples for the DLM/P
- Emulsion + pearl phase
- Polyol + isocyanate + catalyst
- Adhesive + isocyanate
- TPU production
- TPU modification
- Detergents + additives
- Adhesives with colors
- Polymer mixtures
- Oxidation solution with oil solution = reverse emulsion
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).
