The basic parameters used in ball mill design power calculations, rod mill or any tumbling mill sizing are material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating solids or pulp density, feed size as F80 and maximum chunk size, product size as P80 and maximum and finally the type of circuit openclosed ...
difference roller mill with ball mill in energy consumption. The grinding capacity of the vertical mill is stronger than that of the ball mill, but the impact consumption is less than the ball mill vertical roller mill vs ball mill first of all, from the appearance point of view, there is a big difference between the vertical mill and the ball mill
Vertical Roller Mill VRM The power used for the actual grinding process while grinding raw materials, depends mainly on the hardness of raw materials and the type of mill used, i.e. ball mill or vertical roller mill. Typically, the motor of the ball mill consumes about 14 - 15 kWh ton of raw mix whereas the VRM motor uses 7 - 8 kWh ton.
Aug 30, 2019 1 Calculation of ball mill capacity. The production capacity of the ball mill is determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting. There are many factors affecting the production capacity of the ball mill, in addition to the nature of the material grain size, hardness, density, temperature and humidity, the degree of ...
Specific power consumption of ball mills for a cement mill is the equipment used to grind the hard nodular clinker from the cement kiln into the fine grey powder that is cement most cement is currently ground in ball mills and also vertical roller mills energy consumption is typically half that of a ball mill the main measure of fineness.
Oct 23, 2015 This mill is a major improvement of the cement grinding systems known today which are ball mill, roller press HPGRball mill, vertical roller mill and closed-circuit roller press for finish grinding. ... Grinding of cement to a lower Blaine value will reduce the specific power consumption ... Ecs calculation. Horomill motor power 2,126 ...
HRP - Hydraulic Roller Press 2 Increase energy efficiency and throughput Main features High-pressure roller grinding of cement clinker and hard brittle materials is a This makes it possible to increase the throughput of a given size ball mill and - Two types of wear lining are modern and very energy-efficient reduce the specific power consumption available welded hardfacing process.
Upgrading a conventional ball mill with the Hydraulic Roller Press for semi-finish setups can increase production by up to 100 per cent or more, while also reducing specific power consumption by approximately 30 per cent.

The following equation is used to determine the power that a rod mill should draw. The Bottom Table lists many of the common size rod mills giving speed, loading and power data. The rod mill motor power is in horsepower at the mill pinion-shaft. For different length rod mills power varies directly as rod length. For difference between new and worn liners increase power draw by 6, and adjust ...
These days, the vertical roller mills have been widely adopted. AStructure 1 The rollers are hydraulically pressed against a disc table and the feed is ground between the rollers and the disc table. 2 The classifier is housed above the rollers. BFeature 1 The power consumption level for grinding is lower than that of tube ball mill.

Mill Power Consumption Example. Ball mill 3.5 m x 3.5 m Rubber lining 75 mm Mill volume charge 40 Grinding balls diameter 70 mm Mill operational speed 17.6 Calculate the optimum power consumption to operate the mill. Solution
Scale-up criterion is the net specific power consumption, i.e. the power consumed by the mill rotor itself minus all mechanical and electrical losses divided by the feed rate of solids. For the full scale mill, specific power is multiplied by the feed rate to get the net mill power.
Aug 19, 2019 41 Specific power consumption of roller press is the lowest among ball mill amp vertical roller mill system. However, detail study on project basis for instance plant layout, project costing, Return on investment should be carried out to come to a final decision. 42. 42 8. Chapter -8 Bibliography Holcim Ltd.-Holcim guide.
Power consumption and semi-product quality do not change, but the capacity of the roller press increases by at least 10 per cent. To meet the requirements set by the ball mill capacity, the dynamic separator rotor speed of the roller press increases by 2-5 per cent.

Why install Roller Press in Cement Manufacturing Plant. The overall trend is to increase the capacity of pre-grinding bed, and transfer 60 to 70 of of the ball mill functions section to it and high fine airflow classification equipment to complete the system, with a large range of increased production and power
The article considers topical issues of energy saving in cement production with the use of a technological grinding complex, which includes a press roller grinder and a ball mill. Rational conditions of grinding are proposed for pre-shredded material through the installation of blade energy exchange devices BEED in the mill drum. The loading level in the first chamber varies periodically ...
It is also used in the minerals industry. As far as power consumption is concerned the Horomill ranks between the high-pressure roller press and the vertical roller mill. It undoubtedly has advantages over the high-pressure roller press that was introduced to the market in 1985. It uses substantially lower specific grinding forces in closed-circuit
