The SERVOLIFT blending system is based on the principle of free-fall mixing (blending in a container) for free-flowing powders and granulates. The inclination of the blender to the rotary axis - whether interchangeable containers or a firmly-clamped blending container - ensure highly efficient blending or homogenization in a very short time, depending upon the products. One need not install baffles (blending elements) in the head region of the blender container. Thus one blends in a closed system.
