DLM/FS
Solid-Liquid Inline Mixer
Continuous homogeneous mixing of solids with liquids
The INDAG Solid-liquid Inline Mixer type DLM/FS is used for the continuous mixing of liquids with solid components. The solid components can have sizes up to 20 mm (spherical diameter) or be powdery. Usually, the liquid content is the larger portion by weight. Depending on the geometry of the mixing elements, the solids can be mixed in gently or with a higher shear rate. This ensures that powders are finely distributed, and larger solid particles are not damaged during mixing. It is also possible to mix solids into foams without damaging the foam material. A few examples from a wide range of applications are: Mixing fibers or powders into polymers, mixing pigments with carrier substances, and granulates in liquids, mixing powders into silicones, ...
Advantages of DLM/FS
- Very good self cleaning during CIP-cleaning
- Homogenously mixing of small concentrations (0,1% mixing ratio); very homogenous mixing result.
- Energy efficient mixing process
- Mixing energy can by changed by frequency inverter
- Temperature increase less than 1°C
- Gentle mixing of shear sensitive products
- Easy dismounting for manual cleaning
Technology of DLM/FS
The INDAG Solid-liquid Inline Mixer type DLM/FS consists of a feeding zone and a mixing zone. The liquid and solids are fed into the feeding zone, from where they are transferred to the mixing zone by means of a screw conveyor. The mixing zone contains mixing elements in the rotor as well as the stator. Thanks to the special arrangement of mixing elements and feeding zone, the ingress of gases into the product is limited to a minimum. At the discharge end, the mixed product is fed virtually pressure free to the next processing stage. The mixed product either enters a buffer container or is fed to a pump. Both stator and rotor are available as heated versions (double-walled). For machines with frequent manual cleaning cycles, and because of the easier maintenance, we recommend a machine frame with the mixer housing mounted on the „Easy clean“ carriage. The DLM/FS is perfectly suited for CIP cleaning. Optionally, every mixer can be fitted with a double acting mechanical seal or a stuffing box seal. The DLM/FS comes in various sizes, and is suitable for use in explosion-hazarded zones G2, D21, and D22 (ATEX). We offer rental machines for tests on the customer’s site or at INDAG.
