LOESCHE’S LARGE CEMENT MILL TYPE
LM 72.4+4 CS
COMPLETES ITS PERFORMANCE
TEST WITH BRILLIANT RESULTS.
One of the largest cement mills was purchased by DG Khan Cement Pakistan with the vision to curtail
power consumption and keep minimum inventory due to commonality and interchangeability of spare
parts between raw mill and cement mill.
In September 2018, LOESCHE has successfully completed its performance test at the HUB cement plant
in Pakistan. The LOESCHE mill type LM 72.4+4 CS has easily produced 460 tph of OPC Cement with
5% Gypsum and 95% Clinker at a product fineness of 3,300 Blaine.
Outstanding results have been achieved with regards to low specific power consumption. The total con-
sumption of the mill, classifier and fan was 24.4 kwh/t. This marks a historic milestone in the operation of
very large cement mills.
Auxiliaries within the total grinding plant have additional 1.6 kwh/t. A guarantee of 27.3 kwh/t was given
at 3,200 Blaine. Our distinguished customer can expect even better operational results after one year of
plant operation.
Those values represent LOESCHE’s highly efficient mill operation and LOESCHE’s philosophy of giving
very conservative guarantee values.
The mill operation is extremely smooth. Vibration levels are hardly measurable.
As the cement mill was much earlier commissioned than the clinker production line, already in May 2018
the LM 72.4+4 CS produced cement with clinker from different sources at a fineness of 3,900 Blaine.
In the very first industrial operation this mill had excellent results, too. Specific power consumption of mill,
fan and classifier then was 26.0 kwh/t. Average of the first 40 hours of industrial production was 395 t/h
at 3,900 Blaine.
The excellent performance is a result of extensive research and development work of the LOESCHE pro-
cess engineering division in Duesseldorf in cooperation with the LOESCHE group member
aixergee,
specialised in computer simulation, Aachen, Germany.
Loesche is highly obliged to the owner, CEO and Management of DG Khan Cement Pakistan for reposing
high level of confidence and trust on Loesche innovative technologies.
