Stage 2:Value chain activities and

linkages

I - Stage of Materials Preparation

1 - Limestone:

- Limestone is exploited by the method of explosive

drilling and layer cutting as required in the exploitation process and planning.

- After that, limestone is shoveled and transported to

hammer crusher by large capacity equipments Here, limestone is broken into 25 x 25 ballast and brought by conveyor to preliminary classification store, then

separated into two typical piles of 15.000 tons

mixed Materials

Trang 20

2 - Claystone:

- Claystone is exploited by the method of bulldozing

or shot drilling, then shoveled and transported to hammer crusher by large capacity equipments

- Claystone is broken by hammer crusher to the size

of 75mm (first breaking) and by thread rolling

machine to the size of 25 mm (second breaking)

- After that, claystone is also transported to the

preliminary classification store and separated into two different 6.600 ton piles

3 - Control Additive

- In order to qualify clanker, the Company has

made the process of handling and mixed

blending comply with the regulated Modules

and coefficients

- Therefore, control materials, in addition to

limestone and claystone, also include iron ore (rich in Fe2O3), bauxite ore (rich in Al2O3) and silicic rock (rich in SiO2)

Trang 24

II - Material Grinding.

 Limestone, claystone and control additive are poured into grinder through DOSIMAT and electronic weighing system The

material grinder is integrated with the

combined system of grinding and baking

with intermediary dissociation The capacity

of No 1 grinding line is 248 tons hour, No 2 grinding line, 300 tons hour

Trang 25

 Automatically control sets to adjust the

percentage of limestone, claystone,

bauxite and iron ore into the grinder is

managed by the computer to meet the

analyzed data of QCX system, aiming at controlling to-order manufacturing

coefficients

 After-grinding materials dust is transported

to the homogenization silos by the system

of elevator bucker and aerodynamic

channel.

Trang 26

Trang 27

III - Furnace

 Luu xa Cement Line I is the rotary furnace line using dry method, closed process, 04-layer heat exchanging system (cyclone) and planet-typed cooling system which includes 10 sub-furnaces

 Fuel admixture consists of 85% slack 3 and

15% MFO oil However, at present, the

Company has improved itself to use 100% slack

3 and MFO oil is used only for drying furnace

and supplementing fine coal when grinding coal

Trang 28

 The process of material inputting, grinding,

packing and finally, outputting of Luu Xa Cement Line No 1 is made completely automatic

 Luu Xa Cement Line II is the rotary furnace line using dry method, closed process, pre-baking

system (Canciner) which consumes only 715 kcal

kg Clanhke, grating-typed cooling system, which can create the higher cooling effectiveness, high quality products and facilitate the grinding

IV - Cement Grinding

 Clanhker from Silos, Gypsum and Additive from general storage are transported to grinder’s

bunker by conveyor and elevator bucker

Quantity of Clanhke, Gypsum and Additive are controlled by the DOSIMAT weighing system

Cement grinder of line No I and II operates under the closed process (integrated with intermediary dissociation), capacity of No 1 line grinder is 176 (th) and No 2 line grinder, 200 (t/h) Fineness of after-grinding cement is 3.200 cm2g and moved

to 05 powder cement containing silos by

conveyor, aerodynamic channel Total tonnage

of these 05 Silos is 39.500 tons

Trang 32

Trang 33

V - Cement Packing and Outputting.

 From bottom of containing Silos, passing

discharge door, cement is transported to

bunkers of packing machine or in-bulk cement outputting parts

 System of packing machine includes: Line I

consists of 06 packing machines of 12 taps and

100 tons hour each Line II consists of 02

packing machines of 08 taps and 120 tons hour each Packaged cement will be moved by

conveyor to outputting channels of roadway,

railway and waterway
