Whether ball mill or vertical roller mill (VRM), A TEC offers the expert solution for efficiency optimization to increase mill productivity and/or reduce mill power consumption.

 
HURRICLON®, installed after the mill classifier, again proves to be the best technology for the mill product collection, providing top separation efficiency of up to 94% with low pressure drop around 60–70 mmWg.

We are the specialists for the modification of an open circuit grinding mill to a closed circuit mill with a high efficiency classifier and HURRICLON® to dedust the classifier exit gases.

With the installation of HURRICLON® instead of conventional cyclones, the pressure loss of the classifier circuit and the dust load in the gas to the classifier fan are reduced. The application of HURRICLON® increases the mill output, reduces energy costs, reduces wear rate of the classifier fan and improves the dedusting system.

Another application is the installation of HURRICLON® before EP or bag filter to reduce the dust contents at the filter inlet by up to 96%. This installation will relieve an “over- strained” filter from excessive dust load and increase considerably the lifetime of filter bags.
