HN 1 to HN 4 / H5 to H6

Horizontal Concrete Mixing Plants

Wherever concrete is produced and moved is where you will find SCHWING - Stetter machinery.
With plants in Germany, Austria, USA, Brazil, Russia, China, and India, as well as with more than 100 sales and service
facilities, the group of companies is always close to the customer.
Our wide range of products with something for every application is what makes SCHWING - Stetter the No.1 system supplier
for concrete machinery worldwide.

Stetter Horizontal Concrete Batching Plants HN 1 to HN 4 and H5 to H6 incorporate the experience of over 48
years in mixing plant technology.

Depending on the requirements, the HN-type series is equipped with a pan mixer or a twin-shaft mixer. While
designing the plant, high importance was attached to the access thereby facilitating maintenance. In addition, the
generously dimensioned space allows this plant to be offered in a wide variety which can be taken from a modular
system. H 5 & H 6 are plants are for mass concrete requirements and can be suited to the individual demands by
adapting the design.

These high capacity, heavy-duty plants are the first choice wherever large quantities of concrete are required.
Small wonder that the Stetter H series plants hold the national records in PQC production (5050 cu.m of concrete
in 1 day) and also in dam concrete production (6020 cu.m in 1 day)

STETTER PAN MIXERS

YOUR GUARANTEE FOR QUALITY CONCRETE

Stetter pan mixers guarantee production of quality concrete in all slump ranges as they mix intensively, thanks to
short mixing paths both horizontally and vertically.

Therefore, homogenous concrete is produced with Stetter pan mixers with short mixing times and low energy
input. The mixing tools of the Stetter pan mixer are designed for extremely low wear. The spring-mounted mixing
arms can be adjusted quickly without difficulty and are protected against wear by polyurethane sleeves. Upon
request, our mixers can also be made available with shovels made of syntethic material for particularly long
lifetimes instead of the standard mixing shovels made of special chilled cast iron.

The mixing trough is lined with replaceable wear plates on the inner and outer wall as well as on the bottom. The
mixing trough bottom can be lined either with normal wear plates made of special steel or special chilled cast iron
tiles depending on the characteristics of the aggregates to be handled. The wear plates on the bottom can be
turned upside down. Due to all these characteristics we have been able to extend the lifetimes of our mixers
considerably.

The pan mixer can be equipped with upto three hydraulically actuated discharge gates which are driven by the
mixer motor. The dust-proof mixer cover can be opened up to 70% for maintenance and cleaning.
High-pressure cleaning system is available as additional equipment.
Agitators with reinforced agitating tools experience particularly low wear.

Power failure? Taking this into account, we have integrated a hydraulically operated manual discharge device.

Large-dimensioned mixer discharge with hydraulically actuated sliding gate for fast discharging. Wherever you employ the pan mixer for production of ready-mix concrete or in precast concrete factories - you produce quality concrete.

Excellent mixing effect with short mixing and discharge times, a wide range of applications as well as low wear: these are the characteristics of Stetter twinshaft mixers compact in design with two mixing shafts rotating against each other, they are made of high-strength heat-treated steel for a long life. Thanks to Stetter's heavy-duty mixing unit, an intensive agitation of the mixture is reached resulting in fast homogeneity of the mixture. The new
compact drive concept offers numerous advantages in daily operation. At  first there is an easy access to all components of the mixer for maintenance and repair. And, thanks to the monobloc design with motor and gearbox
forming one unit, misalignments and deviations in angles between the axles cannot cause problems.

The mixing arms, made of high-quality cast steel, are arranged on the two hexagonal mixing shafts in a spiral shape. A large overlapping of the tools and a low filling factor were envisaged. An intensive mixing of the concrete is
guaranteed together by the flow-supporting blade configuration. Moreover, the low peripheral speed and the special design of the mixing tools as well as the application of high-quality cast material provide for a long  service life of the wear parts.

Even more: the mixing shafts are sealed towards the interior with a slide ring seal. An automatic grease lubrication system can be supplied for these four slide ring seals as an option.

Durable spherical roller bearings are used for the mixing shafts. The bearings are arranged outside of the shaft sealing and accommodated in a separate housing. All these features result in low maintenance requirements and save
time and cost.

Optionally available: a special mixing unit for coarse grain for production of dam concrete. This enables the use of aggregates up to a grain size of 150 mm.

The robust and high - capacity mixing unit is designed to be particularly energy saving The large - dimensioned skip with an optimum shape guarantees complete emptying.

The mixer discharge for filling truck mixers. Forced dedusting from the mixer. The cement weighing system for up to seven types of cement. Discharge into open truck.

QUALITY AND RELIABILITY

We attach special importance to tried and tested firstclass 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 with the most modern test and simulation tools during their development, an extensive
final testing ensures constant high quality.

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 totheir 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.
