For cement manufacturers, the quality of the end product depends on a range of carefully monitored production processes, such as grinding. FLSmidth patented its first ball mill for grinding clinker in 1892. Easy to install, FLSmidth’s ball mills are designed to grind clinker, gypsum and dry or moist additives for any type of cement. And because they are designed to keep operating and maintenance costs down, they are the ball mills of choice for many cement plant operators around the world.
Exceeding performance guarantees in Russia
In 2005, FLSmidth signed a contract for a complete cement grinding plant with Sebryakov Cement. Located 180km northeast of Volgograd, the finish mill, a UMS φ4.6x14 is the largest in Russia to date. The contract included the supply of the ball mill, hot gas generator, MAAG CPU planetary gear unit, separator, bag filters, fans and transport system.

The first mill feed started on 25 November 2006 and 23 days later, the acceptance certificate was issued. And the results? Output and total production exceeded FLSmidth’s guarantees, while power consumption per tonne was almost 14.5 per cent lower.
