coke-breeze

The black-meal process is used for the manufacture of cement through an MVSK in which the fuel (usually low-volatile coal or coke-breeze) is interground with the raw materials, viz., limestone, clay and additive (s).

2.1 Fluidized-bed process 1993

The preferable specification of coke-breeze or any other fuel for the VSK process are as follows:

4.1 Geological investigations 1993

Different fuels of various mixtures have been used at Paggau ranging from anthracite dust to coke-breeze and petroleum coke, the application of which in all the cases has been reported to be successful.

3.1 Small cement plants in India 1993

Capacity: 40 tons for limestone, and 30 tons each for clay, coke-breeze and additive

Chapter 17 1993

A perusal of the production costs given in table 12 indicates that nearly 26 to 29 per cent is by way of cost of fuel (coke-breeze) and another 16 to 18 per cent by way of cost of power.

Chapter 13 1993

The economics of the small-scale manufacture of cement in India has been found to be particularly sensitive to the cost of fuel (coke-breeze), which depends upon the transport distance, as well as to the capacity utilization of the plant during operation.

Chapter 13 1993

In certain cases additional equipment may also be required, e.g., driers are required for drying of clay and coke-breeze in plants situated in regions of heavy rainfall.

10.1 Market assessment 1993

Once the demand/supply position is assessed, the next important phase of the pre-feasibility study is the search for the required raw materials, as well as fuel like coke-breeze, both in terms of quality and quantity since the successful operation of a cement plant, to a large extent, depends upon the type of raw materials and fuel available.

10.1 Market assessment 1993

Clay, coke-breeze and additives are directly unloaded/stored in the storage yard.

7.1 Plant flow-sheet 1993

A preliminary raw-mix design has been worked out based on available raw materials and it is comprised of 69.50 per cent limestone, 12.50 per cent ferruginous clay, 5 per cent orthoquatzite and 13 per cent coke-breeze.
