Overview

With the same internal geometry as the DCM range of high shear mixers, the DCL is run at lower speeds on viscous fluids as a low-shear inline blender.  The inter-cavity transfer action of the rotor and stator provide a gentle cutting and folding action at low speeds and this is ideal for mixing shear-sensitive materials. Running at low speeds and with relatively large rotor-stator gaps, the DCL is a tough and reliable workhorse that has been used in many industries around the world for almost 20 years.  Available with flameproof and hygienic design options, the DCL covers a very wide range of applications.

Inter-cavity transfer action

The rotor and stator of the DCL carry multiple rows of mixing cavities to provide the inter-cavity transfer effect as fluid passes through the mixer.  There is no possibility of short-circuiting the mixing action, so all of the fluid is processed uniformly and temperatures are kept tightly controlled by heat transfer fluid inside the stator jacket and rotor cavity.

The patented FDM geometry underlying the DCL covers a very broad range of applications and viscosities.  The geometry can also be varied for special applications with Maelstrom's custom design service.

Description

For inline blending of shear-sensitive, viscous fluids, pastes and polymer streams, the DCL rotor-stator mixer offers unbeatable performance.  Based on inter-cavity transfer principles DCL machines provide ultra-low shear mixing at low speeds and with very low pressure drops.  The ability to incorporate multiple inlet streams and mix widely differing viscosities means that DCL replaces static mixers, pin mixers, kneaders and z-blade blenders in many applications where higher performance is needed.
