Benefits at a glance:

  • Consistently excellent mixing result batch after batch
  • Very homogeneous mixing result in the shortest possible time
  • Optimum disintegration of binders and additives
  • Partial batches up to 30% filling degree possible
  • Segregation-free and fast discharge
  • Robust drive
  • Easy maintenance

Mixer configuration

Application-oriented mixer configuration


Application-oriented mixer configuration

Depending on the application, we offer numerous options for customizing your planetary mixer in addition to our standard configuration.

Drive power

Our planetary mixer can be designed with different drive configurations to meet the maximum torque requirements.


In order to adapt the Froude number to the specific mixing task, the mixer can be operated via frequency converters at the optimum speed for the mixture. 

Feeding sequence

The location of the inlets and the sequence of feeding the materials have an influence on the mixing results and the mixing time. We have the know-how to achieve optimal mixer charging.


Depending on the application and plant requirements, the mixers can be designed with several discharge gates.

Product range

With the comprehensive range of planetary mixers, we offer the right, future-proof solution for every need.

In addition, depending on the application, there is a wide range of configuration options for the mixing units, drives, discharge options, etc.

Our planetary mixers are available in sizes from 0.25 to 4.0 m³ and can be fitted with a range of additional options depending on your requirements. Benefit from our experienced and competent specialists when selecting the mixer.

Technical systems


Mixing concept

EPM 3000 FDD.psd

Mixing concept

The mixing system works with mixing tools driven from above, which move on a circular path and additionally around themselves. This ensures uniform, complete mixing of the material in the mixing trough without dead spaces.




The robust planetary gear units are developed and manufactured in-house and offer maximum efficiency, operational reliability and a long service life. For optimum lubrication, the precision gear set runs in a generously dimensioned oil bath. This also serves for optimum heat dissipation, which eliminates the need for additional temperature monitoring.

Electric motor

We only use high-quality mixer motors with temperature monitors for our planetary mixers. They are specially designed for the load cycles that occur.

Hydrodynamic coupling

The hydrodynamic coupling protects against mechanical and electrical load peaks and enables soft starts under full load.

Speed monitor

A speed monitor is installed as a further safety measure.

Options & accessories


Mixing blades

Depending on the application, the mixers can be configured with reversible blades made of chrome hard casting, polyurethane or carbide.

Mixer trough lining

Precision-engineered elements in abrasion-resistant materials are available as linings for the mixing trough.

Fast discharge device

The fast discharge device is a movable clearing blade that is lowered for fast, low-residue emptying of the mixing trough. This reduces emptying times and at the same time reduces wear and power consumption.


In order to avoid agglomeration in complex mixing tasks, a agitator can be used. The design of the agitator is determined according to the application.


Our planetary mixers can be equipped with a manually or hydraulically operated device for taking mixture samples at the front end wall. This possibility is a key advantage, especially in the production of demanding concrete formulations.

Electrical terminal box

All the cabling can optionally be connected to a terminal box for easier installation. This reduces assembly costs on the construction site.

Automatic lubrication system of the mixing stars

Lubrication of the rotary union on the mixing stars is automatic by means of spring-loaded lubrication cartridges, which are well protected in a robust housing.

Non-stick lining

To significantly reduce buildup on the bottom of the actuator, a replaceable PE liner is recommended.

Moisture and temperature measurement

For measuring the moisture or temperature of the mixture, our planetary mixers can be equipped with probes from any major manufacturer. Thanks to its design and also due to the intensive movement of the mixture, the planetary mixer delivers particularly reliable measurement results.

Machine and plant accessories

Skip hoist and weighing system

Skip hoist and weighing system

We offer customized solutions for fast and clean feeding of the mixer with aggregates as well as for recipe-accurate metering of the different mixture components.

Mixing trough cover

The dustproof mixing trough cover for our planetary mixer is equipped with large maintenance hatches opened with the aid of gas springs. Optional custom connections for feeding, venting, video monitoring, or color and fiber addition are available upon request. Dust can be successfully captured by means of vent socks or an active filter.

Water dosing

Depending on the requirements, water can be introduced via a baffle plate or spray pipe system (with or without pressure). The water nozzles of the pressurized spray pipe system are designed to handle pure or recycled water. Optional steam injection systems for the production of hot concrete are available upon request.

High-pressure cleaning

Our tried-and-tested high-pressure cleaning system with nozzle heads rotating in three dimensions is characterized by its excellent cleaning results and low water consumption. For cleaning the discharge hopper, the high-pressure cleaning system can be extended with an additional ring pipe system. In dual mixer plants, only one high-pressure system is required for cleaning the two mixers alternately.

Discharge hopper

We offer proven standard as well as individual solutions for mixture discharge. Furthermore, various linings as well as additional functions (drip protection, swiveling extensions, etc.) are available.

Reconstruction of mixing plants

Turn old into new

We are highly experienced when it comes to retrofitting existing concrete mixing plants. It is possible to modernize the technology of an existing mixing plant at a reasonable investment. As an added benefit, this modernization can significantly increase the throughput rate of the plant. Installing a mixer with a greater performance, adjusting the weighing system and batcher as well as renewing the control system will make the plant much more competitive.

Besides planning, designing, and manufacturing the tailor-made plant according to on-site requirements, our experienced team also offers to install or commission the system.
