INTRODUCTIONBirla group and the Indian
history are intertwined.Ghanshyam Dasji Birla, the
first of the Birla's was closely associated with freedom struggle.
BCW is a unit of mp MP Birla group of Birla corporation Limited.
The product “BIRLA PLUS CEMENT” is one of the market leaders and continuous to consolidate it’s leading position in the market.
BCW is one of the most modern cement plants.
ISO 9001:2001 and ISO -14001 Certifications.
MINESThe basic raw material required is limestone.
This limestone requirement of cement plant is met from captive mines.
Mining Lease of 760.692 hectare.
STACKER & RECLAIMER Linear luffing non-slewing type of stacker is
used. This makes roof type stockpile. Stacker can move to and fro on the rail by
means of motor. A control room for speed, boom distance and other activities.
LIMESTONE RECLAIMER (BRIDGE TYPE) Reclaimer we loosened the material of pile. Materials loosened by the harrows slides down the pile slope. At the base of the pile it is scrapped by the shovels of the scraper and carried away to the belt conveyor.

RAW & COAL MILLMaterial gets grind by VRM in powder form.VRM is ideally suited for combined grinding and
drying.Capacity : 300TPH (RAW MILL)
40 TPH (COAL MILL)
Main units of Mill sections are as follows:
Vertical Roller Mill Dy. Separator Bag house Bucket elevator Air slide & screw conveyors MAIN PARTS OF ROLLER MILL HOUSING ROLLER PAIR NOZZLE RING HYDRAULIC INSTALLATION DAM RING
STORAGE SILO
Silo consists of : Silo Material distribution Central chamber Outer chamber
SILO DETAILS SILO HEIGHT : 76 m SILO DIAMETE : 22m CAPACITY : 26,000 T
KILN SYSTEMMost essential part of a cement plant and has to be
operated continuously for as long as possibleThe major components of the kiln system are. Preheater Pre calciness Kiln Tube Clinker grate cooler The main function of the Preheater cyclone is the preheating of the raw meal, from outlet hot gases of kiln.Every stage cyclone performs the two functions. It heats up the raw meal in the gas stream. It separates the raw meal and discharges it via the meal chutes.
KILNThe rotary kiln consists of a steel tube with a length to
diameter (L/D) ratio between 10 and 38.The inclination of 2.5 to 4.5% together with a drive to
rotate the kiln about its axis at 0.5 to 4.5 revolutions per minute.
Kiln has these parts: Rotary kiln tube Supporting roller stations Kiln tyre Rotary kiln drives Rotary kiln longitudinal guide (Thruster block)
CLINKER COOLING & STORAGEGrate coolers are preferably used in modern installationsThe speed of cooling influences the ratio between the
content of crystalline & liquid phase in the clinker.CLINKER STORAGE PILE Capacity : 60000 MT
CEMENT MILL In the cement mill various equipment’s are used for various
purposes. In cement mill area we first mix gypsum in clinker and then effeminate the mixture to make cement.

SAFETY Safety is utmost requirement for any plant because by taking proper
measures against accident we can increase the profit of company and can save manpower from injury.
ACCIDENT: Unwanted undesirable events which has potential to hit injury to a person or a loss of property”
CAUSE OF ACCIDENT: Unsafe act- 85-90% Unsafe condition- 10-15% UNSAFE ACT: UNSAFE CONDITION: Lack of knowledge No provision of safety
attachment Lack of attention Leakage of oil, water, steam etc Hurry Dust fumes & temperature Violating safety Condition of Ladder/scrapped/stair Overconfidence Worry, Lack of experience, Fatigue
