Several energy efficient options for cement grinding are available today such as vertical roller mills, roller presses (typically in combination with a ball mill), and clinker pre-grinders with ball mills. Ball mills have been the traditional method of comminution in the mineral processing industries and continue to operate with old generation.
Jan 01, 2021 A two-compartment ball mill with a highly efficient separator is still procured for new cement grinding units installation, although the vertical roller mill has now become a true competitor and alternative for ball mill and has increased its market share in the cement mills in recent times.
Pfeiffer’s modular mill solution enables flexible use in any place, bringing cement producers closer to their customers. This compact system is suited to producing all types of cement – perfect for local cement producers and market entrants as well as for large construction companies aiming to expand their position by manufacturing cement on the spot.
Energy saver In the cement manufacturing process large fans draw air through the kiln, precalciner, mills and filters to an ex-haust stack. Many smaller fans push the air into the grate cooler to reduce the temperature of the hot clinker leaving the kiln 1. All these airflows have to be adjusted and controlled as atmospheric conditions, process.
Plant is installed with three mills, in which two mills (CM-1 5) are of ball mill type and other one is vertical roller mill (CM-3) type. The design capacity of the mill is 3TPH, 5 TPH and 15 TPH.
Cyclone preheater, also known as suspension preheater, is the main cement equipment commonly used in the new dry process cement production line. It is the main gas-solid reaction unit of the cement raw meal pre-decomposition system, which makes full use of the high-temperature exhaust gas discharged from the kiln tail and the high-temperature flue gas generated by the combustion at the.
