The BOLZ-SUMMIX conical screw dryer and mixer both use the tried and trusted system of a rotating, self-supporting mixing screw. It is only attached at the top to a rotating swivel arm, which moves it as close as possible along the walls of the container, thus ensuring intensive but gentle mixing of both powders and other, comparable bulk goods.
The complete drive unit consists of a drive system with separate motors for the arm and the screw, located at the top and centrally within the lid. The easy maintenance and exchangeability of the systems was one of the main specifications for the standardisation and design of the BOLZ-SUMMIX conical mixers and dryers.
Our modular and cartridge constructions for seals and bearings, together with the robust construction of the drive and swivel arm, ensure maximum availability and minimum downtime. The drive principle can be implemented either by means of a bevel gear or a belt drive. Both are proven technologies that have been used with great success in many installed systems. Each design has its own, special characteristics, its own advantages and a wide range of applications.
