Cost: The investment cost for a grinding plant with planetary central drive is according to the Maag Co. somewhat higher than that for a mill drive with girth gear and double pinion; ... The largest planetary gears for ball mill drives in the cement industry supplied at this writing by the Maag Gear Wheel Co., have a transfer capacity of 8 MW.
Before the invention of the cement ball mill, cement grinding is completed by cement crushers, which has disadvantages of complicated process, pollution, and more area occupied. Cement ball mill started in the 1960s, after the ball mill has been enlarged, the conditions have been created for reducing construction investment and production cost ...
The vertical roller mill is less power consuming. The energy consumption of a vertical roller mill is around 75% of that of a ball mill of the same capacity. Vertical roller mills can be transported in parts and constructed onsite, avoiding difficult logistical issues and associated costs. The fineness of product cement can be adjusted easily ...

Generally, every cement grinding system has own advantages and disadvantages. When you choose the cement mill, especially for cement mill update, firstly, you should consider some conditions, such as original equipment, raw material, investment and etc. Then, compare several suitable solutions and select a costeffective cement mill.
Features of vertical cement mill. Vertical mill can dry and grind materials with moisture up to 10% at the same time; Vertical mill has simple processing, compressed structure and small building space. The floor area of vertical mill is 70% of ball mill. Building space is 60% of ball mill system. Outdoor arrangement can directly decrease the ...
A modern dry process cement plant, with efficient configuration of the grinding and pyroprocessing systems typically consumes less than 700 kcal/kgcl thermal energy and 100 kWh/mt of electrical energy. Cement plants are designed based on the raw materials and fuel samples tested by the equipment supplier.

According to our analyses, the cement plant of the future could reduce emissions by up to 75 percent by 2050 compared with 2017. Around 20 percent will come from operational advances, such as energyefficiency measures and clinker substitution. An additional 10 percent will come from alternative fuels—however, the availability of alternative ...
In the project design, we will carry on the targeted design to these aspects, in order to lower the cement plant costs and obtain the best investment benefit. A cement plant built by AGICO. 2. Simplify process flow and reduce project scale reasonably. Engineering design is the key link to control the investment of a cement plant project.
Grindability of a 95/5 OPC at various Blaine fineness: o 2732 kWh/t at 3,000 cm²/g. o 3947 kWh/t at 4,000 cm²/g. o 5869 kWh/t at 5,000 cm²/g. Every 100 cm²/g increase in cement fineness increases the mill power consumption by 12 kWh/t for a closed circuit mill 23 kWh/t for an open circuit mill, a sheer waste if this is not required ...
