patent - Cement industry news from Global Cement
The patent addresses methods for increasing the efficiency of cement and mineral grinding by using sustainable materials. The patent relates to methods for improving the efficiency of grinding materials such as clinker and limestone using glycerol derived from biofuel production in combination with various grinding additives.
US5650005A - Process for high free lime content in cement
A source of free lime is introduced into a cooling zone of a cement kiln in an amount to elevate the free lime content to a content of 0.6 to 2.0% by weight. This addition is made without altering the normal or standard process operating parameters of the kiln for cement clinker production.
What is Cement Clinker? Composition Types and Uses - Civil
Its production has decreased in recent years because sulfate resistance can easily be obtained by using granulated blast furnace slag in cement production. Low Heat Clinker It contains 29% alite 54% belite 2% tricalcium aluminate and 15 % tetracalcium aluminoferrite with very little free lime.
US5572938A - Oxygen lancing for production of cement clinker
Oxygen is lanced into the main combustion reaction of a cement kiln to increase heat transfer to the clinker bed and to increase clinker production. Oxygen is separately lanced along the floor i.e. the lowest wall of the kiln to delay mixing with the flame to provide deep staging.
Power-saving method of production of the portland-cement clinker
The invention claimed in the patent relates to the field of industrial production of Portland cement clinker dry semi-dry wet and combined methods for disposal of industrial wastes-precipitation treatment facilities 1-11 .
US Patent for Plant for producing cement clinker with
A cement clinker production line is known from WO 200109548 adjacent to the calcinator of which a separate reactor is installed which is again filled from above with waste materials which are to be combusted in the reactor using tertiary air from the clinker cooler.
Cement Kiln - an overview ScienceDirect Topics
An important parameter in clinker production is free lime which is usually used to identify how the clinker is burnt 69 . The appropriate free lime level is useful to monitor the kiln process and to achieve considerable thermal energy savings 70 . Figure 9.15 shows the free lime data generated from the simulation. The result shows that only
Cemtech looks ahead on the road to cement industry
The increased use of cementitious materials such as fly ash and granulated blastfurnace slag is limited due to their finite supply which will lead to a higher use of pozzolans to reduce the clinker factor in cement plants. In terms of clinker and cement trade this will result in changing trade patterns. A substantial shift in clinker exports
Method of production of cement clinker
FIELD: the installation for production of cement clinker refers to construction equipment. SUBSTANCE: the installation for production of cement clinker includes a heater which has at least one last cyclone and at least one next to last cyclone which is successively connected with the last cyclone with the help of a gas channel and in which the gas is fed from the last cyclone a calcinator
US20030084823A1 - Method for cement clinker production using
A method for the production of cement clinker comprises the introduction of vitrified slag into the feedstock stream prior to the clinkering zone. The addition of vitrified slag can increase the clinker output rates and/or reduce the energy requirements for maintaining the kiln temperatures.

Cement Production: From Clinker Production to the End Product
4. Cement production. The clinker is processed into different types of cement. Apart from gypsum and clinker various additives such as slag sand trass and fly ash are also ground up with them depending on the type of cement required. The MULTIDOS weighfeeder feeds material into the mill similar to the earlier feeding into the mill.
