Wherever construction sites have to the supplied for any length of time with larger quantities of high-quality concrete, mobile mixing plants from Stetter provides special efficiency. It does not matter whether they are used for the construction of traffic routes, dams, landfills or airpor ts, the  M series plants have been designed to handle the task. They can be quickly moved, transpor ted on low-bed semi-trailers and quickly set up again, thanks to the fully installed, pre-assembled compact units. The current development status of the M1 plant has benefitted from our experience with more than 500 mobile plants worldwide. The proven basic concept of mobility has not changed.

The M1 is equipped with Pan mixer and 1.25/2/2.25 is with Twin shaft mixer. The output ranges from 56 cu.m to 100 cu.m per hour thus making it comparable with medium sized stationary plants.

PAN MIXER FOR M1 Pan mixers allow you to produce quality concrete of all consistencies within a shor t mixing time and with low energy input, as they mix intensively due to shor t mixing paths both horizontally and ver tically. The spring mounted mixing arms are protected against wear by means of polyurethane sleeves. Instead of the standard mixing paddles made of special chilled casting you can also use, if desired, our mixers with paddles made of a synthetic material that have an especially long tool life. The mixing trough is lined with replaceable inner wall, outer wall and floor wearing plates. You can lay out the mixer floor wearing plates. You can lay out the mixer floor with regular wearing plates made of special steel or special chilled cast tiles. You can turn over the wall wearing plates. The cover of the mixer can be opened up to 50% during cleaning and maintenance work. The mixer can be emptied simply via the slide or trapdoor. TWIN SHAFT MIXER Excellent mixing with shor t mixing and discharging times, a wide range of applications as well as low wear: these are the characteristics  of Stetter's  twin shaft mixers  in a compact design. The high performance mixing plant from Stetter achieves an intensive agitation of the mixture, and thus a fast homogeneity of the mixture. The mixing arms, made   of   high-quality   cast   steel,   have   a   helical arrangement. The design features a large overlapping of tools and a low fill factor which has a positive effect on the mixing result. Wear-resistant  cast material having a high degree of hardness and toughness are used for the trough lining. ADDITIVE WEIGHER On request,  we will equip our mixers with a two-chamber additive weigher. The additives are discharged via discharge pumps  that are  automatically  rinsed.  The  additives  are distributed over the entire mixture via a set of nozzles. ICE WEIGHER The ice weigher is used for the weighing of flake ice. At the bottom the side walls are slightly sloped outwards which ensures the complete discharge of the container. WATER WEIGHER The dosing of the mixing water is achieved fully automatically by means of a patented weighing, pump and nozzle system. The water system is designed so that you can use fresh water, recycled water or hot water without difficulty. After weighing, a special pressure water pump delivers the mixing water into the mixer.

The Stetter mobile plants allow you to mix anything whether it is dry concrete, ready mix concrete of all consistencies, hydraulically bound bases, recycled material, mor tar or self-levelling floor screed.

Stetter mixing plants can be used anywhere in the world. Whether it is in the arctic cold, tropical humidity or extreme heat, the Stetter mobile plants can be perfectly equipped for every climate zone, and have been proven reliable every where. Thanks to steam injections and the addition of hot water, the winter design permits the production of concrete at temperature of down to
-30ºC.

The in-line silo is used for larger quantities or if more than four kinds of aggregates are used. The weighing takes place on a weighing belt which forwards the aggregates to the feeder skip. Compar tment version; Compar tment version is compact and is suitable for four types of aggregates. The aggregate can be fed either through ramp and loader arrangement or through the Aggregate Feeding Conveyor.

Stetter Control System - MCI 360
Quality from own development and Production

Stetter is well experienced in the development of control systems.   The  solutions  are  perfectly  adapted  to the requirements and needs of the concrete industry. We handle your projects professionally with a high degree of flexibility and reliability and keep on providing you with service, even after installation.  Only this way are we able to ensure customers' satisfaction which we have achieved with several thousands of installed control systems.

1. TRIED AND TESTED SOLUTIONS FOR THE CONCRETE INDUSTRY
Production of concrete requires more than just a simple control system for the mixing plant. The complete stage of expansion   of  our   software for the   control system comprises the preparation of quotations, the planning of orders, production of concrete, fleet management and invoicing.

Different  statistical  evaluations  are required to control production and turnover. If several concrete mixing plants are par t of the total production turnover, networking, a common data stock and a transparent control are the most impor tant factors. All this is offered by Stetter, customized exactly to your specifications.

2. QUALITY AND RELIABILITY
We attach special impor tance to tried and tested first-class  components when selecting the hardware.  Only this way are we able to assure you of smooth operation,  even under the most difficult conditions.   Our control systems  are checked the with most modern test and simulation tools during their development, an extensive final testing ensures constant high quality.

3. FLEXIBILITY AND INVESTMENT SECURITY
The architecture of our software produced with the most modern methods of development in our own works guarantees the highest flexibility:  thanks to their possibilities  in configuration,  software  and system offer simple adaptation to your operating schedule-even if it changes in a few months.  Also, preparation of wiring diagrams and manufacture of switch cabinets is done in our own works. So we can  optimally  suit the  control  systems   to our concrete mixing plants.  Upon request, we integrate our control system also in external installations.
