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 grade
Cement grinding Vertical roller mills VS ball mills
For a ball mill grinding OPC to a fineness of 3200 to 3600 cm2/g (Blaine) the cost of wear parts (ball, liners and mill internals) is typically 015020 EUR per ton of cement For an OK mill grinding a similar product, the
EnergyEfficient Technologies in Cement Grinding IntechOpen
The energy consumption of the total grinding plant can be reduced by 20–30 % for cement clinker and 30–40 % for other raw materials The overall grinding circuit efficiency and stability are improved The maintenance cost of the ball mill is reduced as the lifetime of grinding media and partition grates is extended 25
A Review on Pyroprocessing Techniques for Selected Wastes
153 Vertical Roller Mill (VRM) Vertical roller mills (VRMs) with integrated classifiers have been used successfully for many years in cement plants to grind and dry raw materials simultaneously with moisture contents up to 20% by weight Their production can be as high as 400 tons per hour, and they have a drive power of 115

Vertical roller mills are widely used in the concrete and mining fields, and are also used to process coal，lime and gypsum These units can process both raw and recycled materials, while helping to reduce waste and preserve virgin supplies of these materials Capacity: 50250 t/
Loesche Mills for Cement and Granulated Blast Furnace Slag
a Loesche mill, with a grinding track diameter of only 11 metres, was used as long ago as 1935 However, the breakthrough in grinding this type of material on the vertical roller mill did not take place until the beginning of the 1990’s 1935 The first Loesche mill for grinding cement clinker, an LM 11, was commissioned in Joao Pessao, Brazil
What we can learn from Nepalese cement production
Gears for vertical roller mills Open gears Back Overburning of clinker is also avoided, resulting in a more grindable product and lower electricity consumption in the cement mill, as well as reducing CO 2 emissions from both quarry operations and the trucking of limestone the often 3040km from quarry to plant
