DLM/M Gentle Inline Mixer
Gentle mixing with paddle mixing elements
for shear sensitive products
INDAG Gentle Inline Mixer type DLM/M is used to mix homogeneously a diversity of liquids. Even shear sensitive liquids or liquids with high solid content can be mixed. Only DLM/M rotor is equipped with mixing elements. Stator is without mixing elements. Therefore even fibrous particles will not lead to blockage of mixer. Examples of mixing tasks are: Sewage sludge + polymer solution; paper sludge + polymer solution; sewage sludge + water vapor; latex + additives; latex foams + additives; caustic soda + water; lubricating oil + additives; wax + additives. Additives can be mixed gently into foams without affecting the foam quality.
Advantages of DLM/M
- Very good self-cleaning during CIP-cleaning
- No pressure loss
- No blockage entwining (clog) free
- Very homogenous mixing result
- Mixing energy can be changed variable and adapted to product or capacity changes
- Applicable at high pressures and high temperatures
Technology of DLM/M
INDAG Gentle Inline Mixer type DLM/M has only mixing elements on rotor and no mixing elements in stator (mixer casing). Rotor can be equipped with mixing elements of different geometry. Geometry depends on products to be mixed. The DLM/M 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).
