3 CASE STUDY A 15 mio t/a cement plant is having a closed circuit ball mill for cement grinding: The mill has been operating with satisfactory performance in-terms of system availability and output, however power consumption
The energy consumption of the ball mill is very large, which can account for more than half of the total energy consumption of the selection plant The rising cost makes more and more miners face up to the problem of energy saving of the ball millBut what about old mills, and old ball mills?
The results showed that power draw of the cement mills could accurately be predicted by the method proposed in this study Key words: power draw, cement, dry grinding, ball mill INTRODUCTION Energy is the most important cost item in a cement plant About 60% of the electricity consumption for cement production is used for grinding the raw material
This gives good cement performance, and reduces energy consumption by 20-40% compared with a standard ball mill system Capacity of cement mills The cement mills on a cement plant are usually sized for a clinker consumption considerably greater than the ,
Ball mills Ball mills are used for dry and wet grinding of different materials such as cement materials, cement, lime, and ceramic materials PSP Engineering has continuously reﬁ ned the design of its ball mills Horizontal ball mills have become a reliable part of grinding plants Main characteristics of ball mills seated on shoe-type bearings
Ball mills are most commonly used in cement factories to grind the raw material and finely grind the cement The use of ball mills in cement grinding is due to several factors, among which are relatively simple design and high processing rate However, these machines have certain limitations as well
Ball mill is mainly used for grinding in mining (metallic minerals and non-metallic minerals), cement, refractories, chemical, power plant, aluminum, building material, glass, ceramic, steel slag and fly ash, ectIt follows more crushing and less grinding principle to save energy The feed size to ball mill shall be smaller than 25mm, the output size can be adjusted by revising steel balls ratio

SAG is an acronym for semi-autogenous grinding SAG mills are autogenous mills that also use grinding balls like a ball mill A SAG mill is usually a primary or first stage grinder SAG mills use a ball charge of 8 to 21% The largest SAG mill is 42' (128m) in diameter, powered by a 28 MW (38,000 HP) motor
Cement ball mill in the process of production and processing has high grinding efficiency large output and compared with the general ball mill this ball mill can save more energy consumption Our company can design and manufacture a special cement ball mill to meet the actual needs of users according to the output and fineness requirements of users
A typical comparison of three competing technologies is given in Table 1, demonstrating that an efficient ball mill/third-generation separator, CKP/ball mill/third-generation separator and vertical mill on a typical 4000Blaine limestone cement show little overall difference in energy consumption
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 open/closed .
