package consists of Preheater size 95HE81

with Pyro redox for curbing the NO

emissions

to 600 mg/Nm

and kiln of 5.6 m x 85 m.

ACC/Holcim has focused on the best

technology with cost optimisation for this

project and found lot of merits in KHD

Technology in terms of raw material grinding

Cuttack, Ultratech Cement Ltd

Ultratech Cement Ltd. has opted for the latest

MVR mill technology from Gebr. Pfeiffer.

17 MVR mills of the type MVR 6000 C-6 will

soon be producing in India alone.

This order is the first ever direct deal between

Ultratech and Gebr. Pfeiffer, although Pfeiffer

vertical roller mills do form part of the standard

equipment of this Indian cement manufacturer.

Ultratech Cement Ltd. already owns many

Pfeiffer mills for grinding cement, coal and raw

material, including an MVR mill with MultiDrive

for cement grinding.

The MVR 6000 C-6 enables the customer to

act flexibly and grind not only 225 tph of pure

granulated blast furnace slag but also a wide

variety of mixed cements with capacities of as

much as 370 tph. For maintenance purposes,

two opposing rollers of the six active grinding

rollers of equal size can be swung out. This

ensures that the grinding operation can

continue even during maintenance.

As is usual when it comes to orders

placed in India, the order will be handled in

close cooperation between Gebr. Pfeiffer’s

headquarters in Kaiserslautern, Germany, and

Pfeiffer’s Indian subsidiary, Gebr. Pfeiffer (India)

Pvt. Ltd., based in Noida.

The commissioning of the mill, for which

Gebr. Pfeiffer will delegate supervisory

personnel to the customer, is scheduled for

spring 2021.

and symmetrical part designs allow assembly

without tools and in under two hours. All

components are modular and can fit through a

1 m x 1 m door.
