Maintenance of wear parts for a ball mill and vertical mill
For a ball mill grinding OPC to a fineness of 3200 to 3600 cm 2 /g (Blaine) the cost of wear parts (ball, liners and mill internals) is typically 0.15-0.20 EUR per ton of cement. For an chaeng vertical mill grinding a similar product, the cost of wear parts depends on the maintenance procedures, i.e. whether hardfacing is applied. If hardfacingThe parts of the vertical roller mill have low wear rate. Vertical roller mills generate less noise than ball mills. Vertical roller mills usually have small floor area and building space. Vertical Roller Mill Working Principle. When the vertical mill works, the motor drives the grinding disc to rotate, and the grinding roller rotates aroundVertical Roller Mill for Sale AGICO Cement Plant

Review on vertical roller mill in cement industry & its
Now a days Cement plants are producing 75–80% PPC & 20–25% OPC due to high market demand of PPC. Production of PPC is cheaper and it's market rate is also lower than OPC by nearly 25 rupees per bag, so general consumer are attracted towards PPC cement. Cement companies also want to produce more and more PPC The raw materials were mixed in a certain proportion and fed into a vertical roller mill (LOESCHE mill).

Compared with ball mill, its noises are 20~25 decibels. Besides, our HRM and PRM vertical mills are sealed totally, so the whole system can work under the negative pressure condition. In this way, raising dust is vastly reduced. 7.

Why Choose Cement Vertical Mill?
High efficiency. Cement vertical mill is a new type of energy-saving and consumption-reducing cement equipment. It is the best in production capacity and energy consumption among cement mills. Cement vertical mill has a large single-production capacity that can use low voltage and has high grinding efficiency and low energy The vertical roller mill is better to ball mill in respect of overall economy. The final manufacturing stage at a cement plant is the grinding of cement clinker from the kiln, mixed with 4-5%The important role of vertical mills in cement clinker grinding
