“To ensure high margins in the face of rising energy costs, manufacturers must develop production methods which are highly efficient, and which achieve the highest values even in the case of short-term opportunities. In the eyes of the industry, the future is to safeguard and sustain economic efficiency, productivity, and a highly trained and efficient workforce,” he continues.

Through market analysis, Loesche has identified that Realtime Control is the ‘way of the future’ and will satisfy all requirements needed.

“Simply put, the Loesche mill and circuit can be monitored constantly and in real time with the LM Master, making small adjustments all the time to ensure productivity, efficiency, and profitability. This is a software that is designed to monitor and control the full process from feed materials to final product storage.”

The company offers further peace of mind, providing its customers with the opportunity to monitor their mill performance offsite using a mobile device or tablet. 

The mill and circuit can be monitored and adjusted remotely giving the operational manager peace of mind when not available at the control room. Through the use of this software, Loesche engineers are also able to login and conduct diagnostics on the mill and circuit remotely as well.

Over and above the benefits outlined already, Smith notes a new offering from Loesche as well – the offering, for large engineering companies and any Loesche customer, to register on a spare parts portal.

“All new mills sold are loaded onto the Loesche spares portal. Our clients can then, through this portal identify parts and drawings to aid in maintenance and spare part ordering. With the amount of parts in a mill and particularly the long lead items, a customers’ needs can be identified and serviced without getting out of his office chair,” Smith concludes.
