Some electric motors are used in coal mining, while some motors provide the energy for crushing and shredding in the cement industry. For steel mills, on the other hand, a stable input is required to ensure the continuity of their production process in an extremely warm atmosphere. For this reason, they often use special motors for conveyor belts.
