3THINKING GLOBALLY ACTING IN PARTNERSHIP!
This mission statement as the foundation of our corporate philosophy enables us to face the challanges of the global market in the future.
The requirement of our customers of energy and cost efficiency of their facilities led to the decision, to develop an innovative energy saving classifying and grinding s ystem.
CMP head quarter in Dessau/Germany
At the end of the process stood the development of the first industrial prototype with so far unreached performance. The unique low specific energy consumption s ecures, besides other advantages, the economical success of our partners also in future!
Your CMP team

5The material is ideally dispersed in a multistage dispersing disk system and distributed evenly in the air stream at the separation zone, around the rotor.
In the classifying zone the material is affected by centrifugal-, drag- and flow forces. Depending
FuNCTIONAL PRINCIPLE
on cage rotor speed, air quantity and air guide vane positioning, the material is separated into fine and coarse material.
The fine material is separated from the air in a c yclone or filter. The coarse material is dis-charged into a coarse material collection cone.

CLASSIFIER MODE OF OPERATION
Recirculated air mode with cyclone and cooling, or without cooling
Through-air mode with filter
9Especially in the cement production sector it is essential to ensure an effective upper temp era-ture limit to prevent negative impacts as a result of excessively high temperatures. CMP realizes this by means of a fresh air system with a con-trol concept which is especially adapted to the process. Investment costs for c ement c oolers can be saved by this fresh air fl ap s ystem.
COOLING AND DRYING PROCESS
It is possible to dry products during the clas-sifying process with this system. Therefore, the classifi er is charged with hot gas instead of fresh air. For economic reasons and in terms of reducing CO2 emissions, it is appropriate to use existing warm exhaust air, for example from the preheater.

MATERIALS uSED FOR wEAR PROTECTION
In order to guarantee high service life, all parts of the CEMAG Classifier which are exposed to wear are of wear-resistant materials as standard design. The housing parts are lined with mineral stone compound, cast basalt or mineral mortar.
The number and size of installed inspection doors and flaps guarantee an easy maintenance and inspection of the classifier inside.

Since the market launch of the fi rst classifi ers at the end of the 19th century, additional cl assifi er gener ations have been developed pushed f orward by the world-wide demand for more e ffi cient c l assi fyi ng solutions and high-quality products.
The fan and fi ne material separation of the C yclone Recirculating Air-Classifi er of the 2nd gene ration (since approx. 1960) have been installed outside, which led to an improved regulation of the pro duct fi neness.
The CEMAG Cross Flow-Classifi er belongs to the 3rd generation and works with a cage system instead of the traditional counter-wings. The cage is streamed according to the cross-fl ow-principle and thus achieves again a remarkably increased effi ciency.
