Clinker if stored in dry conditions can be kept for several months without appreciable loss of quality Because of this and because it can easily be handled by ordinary mineral handling equipment Clinker is also shipped to grinding plants in areas where cement-making raw materials are not available
whereas the dry cement process consumes 3609 75 MJ/ ton The high energy consumption of the wet process over the dry can be attributed to the mix preparation method adopted prior to burning of clinker in the kiln (water being added to the raw materials to form raw thick slurry) whereas the dry process is only based on the preparation of fine powdered raw meal by grinding raw
Cement can be defined as the bonding material having cohesive adhesive properties which makes it capable to unite the different construction materials and form the compacted assembly Ordinary/Normal Portland cement is one of the most widely used type of Portland Cement The name Portland cement was given by Joseph Aspdin in 1824 due to its similarity in
A cement mill (or finish mill in North American usage) 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 which are more effective than ball mills
Second electrical energy is used to operate various units – in particular raw material and cement grinding systems Today electrical energy consumption in cement works makes up over 10 per cent of the total energy consumption with the energy costs being split almost equally between fuel and electricity
