1. Introduction. Clinker milling is the last step in production of Portland cement. Nodular clinkers produced in a rotary kiln in a cement plant are ground together with gypsum into a fine powder of particle size less than 100 μm and with a surface area of 330380 m 2 /kg for production of ordinary Portland cement (Bye, 1999).The fineness of the particles is a critical aspect that governs ...

Clinker occurs as lumps or nodules, usually 3 millimetres ( in) to 25 millimetres ( in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.

The mill was crashedstopped during various periods. Samples were representatively taken from inside the mill in distances of 2030. cm along the center and edge lengths for selected periods which are 2, 5, 10, 15, 20, 30, 45 and 60 min.. For modelling of grinding process in pilot scale ball mill, determination of the particle size distribution of feed and product of mill is an essential step.

This study investigated ultrafine coal grinding performance of four low to moderatecost grinding media in a laboratory stirred mill. Kinetic grinding tests showed that silica beads generated the finest product size with a P 80 of μm from a feed size of μm while having a specific energy (SE) input of 309 kWh/ton. Nonetheless, the ...

At most manufacturing plants the ball mill is used to grind the clinker and, since the production rate is directly related to the amount of electrical energy supplied, the power of the electric motor used to turn the mill is a firstorder measure of the output achieved. Mills vary in their power input from as little as 200 kW up to 10000 kW.
