****************************

Manufacturing Process :

The production of cement will be based on completely dry process; hence no process waste water will be generated from the plant. Also the cooling water will be through a closed circuit system

 

The manufacturing process involves crushing of limestone, grinding of raw materials, homogenization of raw meal, pyroprocessing, clinker making, clinker storage, and cooling, cement making and blending with fly ash, packing and dispatch.

 

Maaterial Handling:

The plant will have a completely independent limestone crushing plant. 

The Crusher will be located near the mine pit and the limestone will be

transported to the plant site, through a Belt conveying system.

 A limestone Stacker / reclaimer system will be installed for storage of limestone.  The coal and gypsum will be conveyed through belt conveying system and stacking by a mechanized stacking arrangement.

 

Grinding systems for raw materials and coal: 

Energy efficient Vertical Roller mills (VRMs) for grinding raw materials and coal  will be used proposed for both Phases of the project. 

The ground raw meal is stored in silo and  the fine coal is stored in hoppers.

 

Pyro-processing system: 

A highly energy efficient 6 – Stage preheater / ILC (In-line Cacliner) precalciner with  a Rotary Kiln system will be used in this section  for

Phase I. 

An additional kiln system of similar design will be installed in Phase II of this projec

 

Clinker transport and storage:

Clinker will be transported from cooler through Deep Ducket Conveyors (DBC)

 

It is proposed to install a Clinker silo (100,000 Ton) for storage of clinker in Phase I and one  more similar silo in Phase II.

 

The Clinker manufacturing involves

Raw Material Preparation

Raw Meal Preparation

Clinkerisation and

Cement Packing & Storage..

 

Raw Materials :

The Total Minerals required for cement plant are:

 

1. Limestone                                           :  7.0 MTPA ( Captive)

2. Iron Ore                                                :  0.04 MTPA

3. Coal for Clinkerization                :  0.88 MTPA

4. Coal for Power Plant                   :  1.06 MTPA

5. Fly ash                                              :  2.80  MTPA

6. Gypsum                                          :  0.48 MTPA

7. Clay                                                 :  0.28 MTPA

6. Bauxite                                           :  0.05 MTPA

Electrostatic Precipitators (ESP) will be provided to cement mill and Power plant.  

Covered storage systems for coal will be provided for reducing the fugitive
emissions.

Truck tippler system will be provided for unloading of additives  received by road and a covered storage area with mechanized arrangement for additive stacking and reclaiming will be provided. 

Effective pollution control measures will  be provided to control the emissions from the Cement Plant & Boiler:

Other Systems

  • Fuel handling system

This section will include all the necessary equipments like coal crusher, conveyor and drives. Coal from the source shall be crushed into required size and taken to the feed hopper of the boiler room. Coal yard will have separate arrangements for incoming coal and crushed coal to be sent to the hopper

 

  • Ash handling system
  • Air Cooled Condenser
  • Fuel system

 

The following air pollution control systems/ measures are proposed in the Plant

1. All Conveyors will be completely covered with G.I. sheets to control fugitive  

    dust.

2. All bins will be totally packed and covered so that there will not be any chance   

    for dust leakage.

3. All the Dust Prone Points Material Handling systems to be connected with

    de-dusting system with bag filters.

4. All Discharge Points and Feed points, wherever the possibility of dust 

    generation is   there a de-dusting suction point will be provided to collect the dust.

    storage bin through a Pneumatic Conveying system.

 

Water Treatment Plant

Sand Filter, Iron Filter, ACF, DM Plant,Tube Settlers etc.

Pumps Valves, Custom Pipeline Work

 

The required water for the integrated  cement plant operations is

10750 m3 /day for both cement plant & CPP in phase-1

and additional 10750 m3 /day in phase-2.

 

It will be sourced initially by ground water in the plant site.

 

Once the mine pits are formed and rain water harvesting will be done in these pits, and the same will be used for plant purposes.

 

The water required 60 m3/Day for the mining activities will be sourced from  proposed integrated cement plant &  afterwards water will be sourced from reservoir developed in the mining lease  area.

 

Effluent Treatment Plant

No industrial wastewater will be generated from the cement plant.

Wastewater will be generated from captive power plant, which will be treated in ETP.

 

The waste generated during the construction phase will be segregated into non-biodegradable and biodegradable wastes and managed accordingly. The non-biodegradable wastes are further classified into metal scraps, plastics and combustibles, which will be sold and/or disposed appropriately. During operation phase of the proposed project, the municipal waste generation will be handled scientifically

 

Overburden/waste of about 9,25,000 Tonnes will be generated during entire life of mine.

This material will be dumped in ML area and will be used for backfilling

after extraction of limestone. However, topsoil will be used for

green cover development
