MVR vertical roller mills for cement grinding

Two MVR cement mills for Sri Lanka, the pearl of the Indian Ocean

Sri Lanka is known as the pearl, the drop of luck, floating just off the south-eastern coast of India. Gebr. Pfeiffer will supply two MVR 5000 C-4 roller mills for the production of various cement types based on clinker, gypsum, granulated blast-furnace slag and fly ash to this charming region.

The customer, Lanwa Sanstha Cement Corporation (Private) Ltd., belongs to the ONYX Group mainly operating in Sri Lanka and the United Arab Emirates. The contract was signed in February 2019.

In addition to the known technical advantages of the MVR mill, like for instance actively redundant grinding rollers and the extremely low vibration level, which allows cement types to be produced with highest Blaine values, it was the concept of the compact grinding plant that convinced the customer. Due to tourism being strong in the country, especially in the south of Sri Lanka, extensive environmental guidelines were taken into account when planning the grinding plants. Residual dust and noise are only two of these criteria.

Both the building volume and the footprint of the grinding plants to be set up in a closed building are kept to a minimum.

Most of the components of the grinding plants, be it mechanical or electrical, will be supplied by the Indian subsidiary, Gebr. Pfeiffer (India) Pvt. Ltd. The core components of the mills, like for instance the grinding rollers, the tension systems and the gear units, will come from Europe.

Besides the equipment supplies, Gebr. Pfeiffer (India) Pvt. Ltd. will also provide the entire engineering for the grinding plants and make available staff to support and supervise the erection and commissioning and assist with the performance test.

The two grinding plants, each coming equipped with an MVR 5000 C-4 producing about 180 t/h of OPC ground to a fineness of 4000 cm²/g acc. to Blaine, will be set up at staggered intervals.

Delivery of the first plant is slated for the end of this year and scheduled to go onstream in the 2nd quarter of 2020.
