re Troubles in using petcoke. I would like to add to the response of Mr. Ted that traditionally it has been stated that an excess SO3 content of some 300-700 gm per 100 kg clinker can be tolerated in the kiln system.Lower limit will be valid for hard to burn raw materials while the upper one referes to easy burnable raw meals.Apart from adjustment of the …
Cement Storage: The cement clinker which is stored is blended with Sulphates, resulting in the formation of gypsum and anhydrite. It is then fed to mills for grinding which results in the production of cement of different qualities. The cement then is sent to silos for storage and then packed in packing plant.

For cement clinker and blast furnace slag ; higher compressive force is needed compared to limestone and coal. Very Fine material behaves like liquid and therefore de-aeration and pre-compaction is useful. For this purpose Two way grinding system has been developed by UBE for highly efficient grinding of Slag and Clinker.

CLINKER FLINT CLAY POWDER PRODUCTION PROCESS. 1. Crushing of raw materials. The large pieces of flint clays are crushed by the crusher to the fineness (15mm-50mm) that can enter the mill. 2. Grinding. The crushed small pieces of flint clays are sent to the storage hopper by the elevator, and then sent to the grinding chamber of the mill evenly ...
This describes a method for producing cement clinker using petroleum coke with a sulfur content over 4.5% by weight, in conventional equipment and facilities, wherein said method comprises the treatment of the raw mixture to optimize its physical-chemical characteristics combined with the parameter control of the process, obtaining a reduction of the clinkering …
The throughput rate for pure petcoke grinding will be 40t/hr with a product fineness of 2% R 90µm. The mill will be equipped with an SLS 2900 BK type classifier. Due to the high abrasiveness of Indian coal, the mill and classifier will be designed with a correspondingly robust wear protection.
In case study it was observed that : Case-1 - with import coal - SO3 in clinker was 0.4 Case-2 - with 8% Petcoke - SO3 in clinker was 0.55 Case-3 - with 25% Petcoke - SO3 in clinker was 0.9% Case-4 - with 50% Petcoke - …
RB1 Coal – 5,500 Kcal/Kg; Petcoke – <8,200 Kcal/Kg – Lower cost per Kcal for petcoke – Less quantity of petcoke to be burnt at cement kilns 2. Ash Content: RB1 Coal – Maximum 15%; Petcoke – Maximum 1% – Better use of limestone for efficient sulfur capture – Higher ash from coal is absorbed in clinker, enhances clinker volume 3.
Several studies have been carried out on the energy use and CO 2 emissions related to cement production [1, 4, 6, 11, 19].Praseeda et al. [] reported that the energy use for cement production is 2.91 and 4.32 MJ/kg of cement based on two cement plants.This study considers the energy use for raw materials (including limestone), transportation of raw …
The liquid percentage at 1450 0 C can be estimated using the formula. % Liquid content (1450 0C) = 3.0 x A+2.25 x F+S. Where A=Al 2 O, F=Fe 2 O 3, S= MgO+K 2 O+Na 2 O+SO 3 In Clinker. The normal range of liquid phase is 22-27%. Burnability is a reference value for raw meal indicating how difficult it is to burn.
The aim of this replacement was to increase the kiln capacity to 9000t/day without impacting its NO x emissions whilst maintaining a good clinker quality despite a high sulphur content in the petcoke. The installation is now in production and an intervention is planned in the coming weeks to further optimise the operation.
Spain: Cementos Cosmos plans to scale down the production of clinker at its Córdoba cement plant as a result as the high cost of electricity. The Cordoba Day newspaper has reported that parent company Votorantim Cimentos said that clinker grinding operations at the site will continue to ensure a sufficient cement supply in the region.
Cement grinding January 2017 Clinker production July 2017 Plant capacity 3,300 tpd Fuel Coal, petcoke, alternative fuels Raw material preparation Pre-homogenizing storage (limestone, clay, pozzolana, iron ore): 27,500 t Additives 1 storage: 2 x 5,500 t (clay) Additives 2 storage: 2 x 3,500 t (clay) – 2,000 t (iron ore) – 2,000 t (pozzolana)
Grinding of clinker consumes power in the range of 2.5 kWh/ton of clinker produced. These and other pyroprocessing parameters make cement production costly. The pyroprocessing process in kilns and the grinding technologies therefore have to be optimized for best processing.
When it comes to mill control, operators rarely concentrate on pushing mill production when the kiln is regarded as the key. Expert systems on mills should be universal and well tuned. Grinding aids can give benefits of 5-15 per cent in production but need to be continuously evaluated for cost effectiveness.
