Bangladesh: Shah Cement has inaugurated the world’s largest vertical roller mill (VRM), supplied by Denmark’s FLSmidth, at its Muktarpur plant in Munshiganj. The FLSmidth OK 81-6 Mill has an 8.1m grinding table and six grinding rollers powered by two 5.8MW FLSmidth MAAG Max Drive gear systems. FLSmidth says that the mill is the largest VRM ever to be installed in a cement plant in terms of dimension, operating capacity and installed power. It was put in operation in September 2018
“We are proud to have the world’s largest vertical roller mill as part of our operations. We selected the FLSmidth OK 81-6 Mill for its exceptional efficiency and reduced power consumption – and we are expecting it to deliver as promised. As the largest single-unit grinding mill in the industry, we expect it to meet our production requirements for many years,” said Hafiz Sikander, Director of Operations, Cement Division of Shah Cement Industries.
The mill is designed to produce Ordinary Portland Cement (OPC), Pozzolana Portland Cement (PPC), Portland Slag Cement (PSC) and slag cement types. It is producing PPC at a capacity of 500t/hr at 3500 Blaine with 15% slag. In addition to the OK Mill, FLSmidth supplied the process and layout engineering, along with site advisory. The supporting equipment included FLSmidth Pfister weigh feeders, FLSmidth Airtech process bag filters, process fans and auxiliary equipment from raw material hopper discharge to process bag filter discharge.
