The Lödige mixing granulator

Machine type

The high-shear mixer is a system for mixing, granulation and sieving of pharmaceutical powders and granulated products. Moreover, it is suitable for a wide range of cosmetics and food products. A three-bladed mixing tool rotates in a vertical, cylindrical mixing vessel close to the wall and to the bottom of the vessel. The shape and peripheral speed of the mixing tool create a vortex-like circulation of the mix. This product movement ensures very short mixing times in conjunction with excellent mixing quality and permits build-up of granulated products. A separately driven chopper is used for breaking up any agglomerated products as well as for moistening and granulation. Liquid addition is either gravimetric or uses a pump to add liquid directly to the effective range of the chopper, so that the best possible distribution is ensured. The optional wet sieve on the discharge ensures a completely homogeneous distribution of the granulate size.
