MMX-PRESS - Special superstructures

Tell us what you require - We will build it for you!

The flexible component construction from TROPPER enables us to suit the grinding and mixing plant to your needs:

TROPPER MMX-Press can be ordered without a crusher or a hammer mill and therefore be used purely as a fodder mixer. The version as stationary grinding and mixing plant is possible because of this component technology. Transport to the buyer is done by truck.


In Finland for instance, due to the wide distances, large amounts of bagged fodder or bulk premix are carried onboard when tours last several days. For this special purpose TROPPER developed a light ingredient container.


The container is mounted preferably on a quad axle truck trailer or a triple-axle semi-trailer in front of the grinding and mixing plant.

Due to the generous cover, filling can be easily carried out with a loader or a loading auger

The individual cells of the ingredient container can be executed as bulk goods cells with suction funnel or as bagged goods compartment for pallets with large doors to enable forklift loading. The bulk ingredients are sucked directly into the mixer and the weight is measured and recorded in the ingredients mixture by the On-Board weighing system.

Built for operation under extreme conditions


Many years of operation of the MMX-Press in Finland with huge differences in temperature and sometimes even iced up controls is just one example of the robust and reliable construction of our superstructures.

Successful drive systems

Auxiliary engine: Standard is the economical powerful Mercedes Benz OM 501 LA (V-form) engine with 260 kW or optionally the inline engine OM 460 with 295 kW.

Direct drive: Tropper direct drive with elastic, compensating coupling.

Both drive options from TROPPER provide, due to the low maximum working revolutions of 1,600 rpm when sucking, for optimal performance and torque at low fuel consumption. Modification for plant oil is possible for both types

Tropper Airblock

With the smooth running Airblock you can count on a well-protected air-end with temperature monitoring.


The MEGA suction station for even more suction performance at low revs. Save fuel and spare the direct drive due to lower rpm despite higher performance

Hammer mill HM 660

The mill is standard equipped with 160 hardened metal hammers (with 0.85 m² filter surface) and therefore also well suited for special purposes such as grinding moist grain. (Grinds up to 35 t/h).
Filter exchange is easy to carry out

Grain crusher QR 600

In the case of the massive, hydraulically adjustable crusher the crushing performance and the crush quality are always the main priorities. The large 600 mm long crushing rollers with a diameter of 400 mm and the proven belt drive enable top throughput with all fodder ingredients. Simple crushing gap adjustment while running is a specialty of the TROPPER crusher.

Magnetic separator (ID 02499)

Despite the strong magnetic force the magnetic separator can easily be taken out and wiped clean.

Original Tropper Suction-Pressure Mixer

Mixer sizes from 3 t to 14 t capacity. The mixer stands out due to its complete discharge, the calibratable weighing unit, the integrated jet filter, the mixture sampler next to the operator control box and the bunker impactor for cleaning the inner walls of the mixer.

Complete draining since 1992

As an operator of mixing plants, you set great store by a quick and clean change of products. Hereby, you can rely on our long-time experience with pneumatic discharge. TROPPER MMX-Press have been drained, according to a simple and efficient system, since 1992 for a simple and effective system: Due to maintenance-free outlet plates, the best possible draining can be achieved without any complex mechanics at the bottom of the mixer drain! In combination with the standard hopper knocker (cleans the mixer wall) and the draining stop, you can achieve impressively clean results. You as customer supply high-quality compound - hence: mix quality - avoid loss!

MMX-Control Profi in Central Operator Controll Box

The lockable and professionally wired operator control box in 7 languages (MMX Control Profi) in stainless steel, heated, for manual and automatic weighing affords multiple possibilities for use.

Additional material hopper in stainless steel


With suction, elastic and mounted very low (optimal height for adding ingredients) with a table and a bag opener for small bags as well as a shaker for emptying the bags fully.

Blower arm with double joint NW 100

The special hydraulic full stream technology enables dust-reduced discharge of large amounts of material due to the 2 joints

Optional discharge screw instead of blower arm

For complete discharge of the mixer contents and for continual throughput crushing (e.g. for biogas plants). When carrying out continual throughput crushing the crushed grain is guided through a rotary feeder.

Fluid addition for oils

Suction system with tubes, regulator and intake lance as well as oil tank (300 l to ca. 2,000 l) with counter (select amount). Figures are displayed on the weighing computer (MMX Control).

Hot galvanized frame components


TROPPER sets high quality standards and has its processed frame components hot galvanized after they have been bevelled!

Sound insulation hood in attractive design

The complete internal coating of the aluminium hood with high quality sound insulation material enables on the one hand effective reduction of the operational noise and on the other hand easy access to the units due to the large cover.


Comprehensive standard accessories

It is a matter of course that all necessary parts such as hoses, suction tube, exchangeable filters etc. are included at the time of delivery so that as soon as you accept the vehicle you can start working with it. TÜV inspection in our works is obligatory for DE and AT.

Your special standard equipment:

Camera set for reversing
Improve safety thanks to the practical camera set with digital display on the monitor in the cab.

Storage box for hose etc.
Made of aluminium, at a low height with trays for suction lances and coupling pieces, weather protection roof over the additional material hopper, tools in a toolbox as well as a fire extinguisher which are naturally all included
