Efficient mixing technology for precise industrial applications
Mixing technology plays a decisive role in industrial production, especially when it comes to precise and gentle mixing. A proven system in this area is the conical screw mixer, which enables homogeneous mixing of bulk materials thanks to its special design.
Our conical screw mixers offer high efficiency and flexibility for a wide range of applications. Whether sensitive powders, granulated materials or demanding mixing processes - thanks to the vertical design, uniform mixing is guaranteed without damaging the material.
The vertical single-shaft mixer and our innovative Promix Batch and Promix Conti systems are also available for specific requirements. These solutions combine state-of-the-art mixing technology with maximum process reliability and energy efficiency.
Rely on first-class mixing technology with a conical screw mixer that optimizes your production processes and delivers the best mixing results.

Promix Batch
When there are frequent product and recipe changes as well as variable processes, so-called batch mixers or discontinuous mixers are used.
They are suitable, for example, for gentle homogenization and generally for the preparation of solid mixtures, solid-liquid mixtures and pasty mixtures. They are also used for disinfection, destruction of agglomerates, granulation, initiation of chemical reactions and dosing during product production.
Reference projects:
horizontal mixer
Product range:
- mixer in batch operation
- horizontal mixer, vertical mixer
- single-shaft mixer, multi-shaft mixer
- paddle mixer
- Conical mixer (with spiral or central mixing screw)
Properties / Variations:
- usable volume
Up to 30m³ - materials
In stainless steel, mild steel and special materials - trough shapes
jacket tube, U-trough, omega trough, double U-trough, cone with dished bottom - mixing principles
In the turbulent area/mechanically generated fluidized bed, in the heap - mixing tools
Single helix, double helix, (conical) mixing shaft, knife heads, side scrapers, special blades (link: screw shafts and blades), paddles, knife paddles - equipment
Armouring, plating of the mixer shaft, wear protection lining of the housing, additional cooling jacket / heating jacket, thermal vanes, CIP, feed hopper, spray devices, electrically or pneumatically operated discharge flaps, inspection openings, special outlet nozzles - designs
Food-safe, ATEX-compliant, WHG-compliant; Heavy-duty, dust- and gas-tight, explosion-proof (Explosion protection up to the highest requirements (ATEX compliant up to Zone 0 or 20)), pressure operation, vacuum operation - seals
Product-specific seals - operating time
continuous operation - If necessary
If required, specially adapted dosing, shut-off and discharge devices
Advantages:
- Reproducible product quality
- Optimal product flow with short mixing times
- As required: from product-friendly homogenization to increasing the shear forces to integrating further process steps
- good accessibility, optimal cleanability
- Increased downtime with maximum system availability
- Solid design for high user-friendliness and minimization of problems
- Short downtimes
- High availability

Promix Conti
The net working time of the device is also increased, as intermediate filling, emptying and cleaning cycles are eliminated. For a given production volume, the mixer and drive can be smaller. Continuous mixers are used, for example, for high throughput quantities and constant processes.

conical screw mixer
Conical screw mixers as batch mixers are the ideal solution for frequent product and recipe changes as well as variable processes. They enable gentle homogenization and precise preparation of solid mixtures, solid-liquid and pasty mixtures.
They are also suitable for sterilizing, destroying agglomerates, granulating, initiating chemical reactions and dosing during production. Thanks to their efficient and flexible mixing technology, conical screw mixers ensure optimum results in a wide range of industrial applications.
