Cement Ball Mill In India

We can not only provide single equipment,such as jaw crusher, cone crusher, ball mill, but also can provide full production line,such as iron ore production line, ore beneficiation production line, etc.

Grinding mill is also called grinding machine, pulverizer or grinder to be distinguished from ball mill.As the key milling equipment, there are considerable differences between grinding mill and ball mill from the outside and inside.

The working principle of the self-grinding machine is basically the same as the ball mill, the biggest difference is that the sag grinding machine uses the crushed material inside the cylinder as the grinding medium, the material constantly impacts and grinding to gradually pulverize.Sometimes, in order to improve the processing capacity of the mill, a small amount of steel balls be added appropriately, usually occupying 2-3% of the volume of the mill (that is semi-autogenous grinding).

The fine grinding of ores is increasing due to the depletion of coarse grained, easily processed ore bodies and the increased need to process disseminated, fine grained deposits.The main reason ball mills are not utilised for fine grinding is the perceived poor energy efficiency generally experienced when grinding to fine sizes.However there is a trend towards ball mill grinding for product sizes below the traditional ball mill cut-off of 45 m.The effect of ball size on the feed and product size distributions in a fine grinding situation was studied.The grinding tests identified a number of trends for fine grinding, including: efficient grind curves forming the same shape as for traditional grinding (exponential decay). the results supporting the claim that fine material is best ground with small media and coarse material with larger media. the smallest charge was most efficient at treating the finer feeds. the smaller charges were very ineffective and inefficient for grinding of the coarser feeds. efficient grind was undertaken by smaller charges than that recommended by bonds ball sizing formula, and operating work index analysis confirming the results of the p 80 -energy analysis.

Controlling material feeding refers to feeding size and feeding speed.To control the feed size, more crushing and less grinding is a good principle.Feeding speed means to send the material into the ball mill cylinder at a moderate speed.

3.The feeding size can be very large and usually can be up to the length as 5% of the roller diameter.The large ball mill's feeding size can be up to 150 ~ 200 mm.The equipment has superior technical performance and is of high capacity.It has high rate of operation and lower metal-worn than the ball mill.

The grinding principle of dry grinding ball mill and the wet grinding ball mill is the same.In addition to whether adding water or not in the grinding process, dry grinding ball mill can be distinguished from wet grinding ball mill by the structure and materials processed.

From the view of method of operation, grinding mill uses the method of dry grinding, while ball mill adopts the method of dry grinding as well as wet grinding.For this reason, there are fewer requirements for the moisture of material in ball mill grinding process.

As we all know, ball mill is the key equipment for grinding materials after crushing, which is indispensable in beneficiation plant, metallurgy, chemistry, cement and other fields.

Our leading products include crusher, grinding mill, ball mill, and complete set of equipment.These are widely used in building materials, roads, railways, bridges and other industries.Ball mill is widely used in the powder production lines, such as cement, silicate, refractory materials, chemical fertilizer, glass ceramics, etc.According to the need of customers, here we have ball mills for sale that can realize both wet and dry production.It has been designed in standard sizes of the final products.We would like to help more and more customers to start their construction industries and business in mining, offer them much more advanced machinery, the best interpretation, and better benefit.

Largest size of clinker is 60mm , 100% damper openning at mill fan , no hole for fresh air at mill inlet also no hole for water injection.Our ball mill is operated manually not automatic.

Lloyd sponenburgh, in his ball milling theory and practice for the amateur pyrotechnician, tells us his explorations into ball milling began when he was faced with having to do all that grinding with a mortar and pestle to achieve small particle size and intimately mix his chemicals.Lloydss book is the most complete and practical resource i know for information on ball milling theory and for plans to actually build your own ball mill.Heres a shot of a nice, double-barrel mill i built based on his principles.
