influenced by the mill speed and separator speed. Ball mill is grinding equipment which is used to reduce the size of clinker into cement. It uses grinding media in the form of balls. Clinker coming from the silo is sent into hopper and mill for impact action. Clinker is introduced into the ball mill.

RRSB, cements from ball mills generally have a rather low slope [n']. In a VRM the grinding takes place by pressure and shear force. The clinker passes within seconds between roller and table. The energy input to the material during one passage between grinding rollers and grinding track is relatively low. The thick

The quantity of grinding aid used in a particular mill is dependent on the size of the mill, feed size, product size, type of clinker being ground, etc. For instance, in large diameter ball mills, the impact force of the grinding media is so great, that a high material surface unbalance prevails in the mill when grinding all types of clinker ...

The use of highpressure grinding rolls (HPGR) prior to ball mills has become a common practice in cement clinker grinding due to significant energy savings in comparison to ball milling alone. The energy savings has been attributed to higher energy efficiency of HPGR at low reduction ratios, smaller particle top sizes in the ball mill feed, and the weakening of particles resulting from ...

The current world consumption of cement is about billion tonnes per annum and it is increasing at about 1% per annum. The electrical energy consumed in cement production is approximately 110. kWh/tonne, and around 40% of this energy is consumed for clinker grinding.. There is potential to optimise conventional cement clinker grinding circuits and in the last decade significant progress has ...

Batch dry grinding tests of cement clinker were performed in a ball mill measuring the power input. The effect of ball size distribution on specific selection functions was investigated. At the initial size reduction stage the experimental results show that the breakage process is more efficient with a maximal specific selection function.

In a ball mill, the particles are ground by repeated impact forces. The material usually needs more than 20 minutes of grinding from mill entrance to outlet, with uncountable impacts take place on this way. Depending on the efficiency of the separator and the Grinding Aid, agglomerates of fine particles are rejected and pass the ball mill again.
