Asia Cement’s Pukrang Plant consists of two production lines with a current installed capacity of 5 million tons of cement per year. The plant is located at Tambon Pukrang, Amphur Pra Buddhabat, Saraburi Province on an area of more than 1,000 rai (about 400 acres). In 1993 the first production line was started with an installed capacity of 2 million tons of cement per year. In 1997, the second production line was completed with an installed capacity of 3 million tons of cement per year. Both production lines used the dry process technology.
The limestone quarry is located nearby the plant. Blasted rocks are conveyed to the crusher by a fleet of dump trucks.
Crushing and Storage
The plant has two limestone crushers which can reduce the limestone lump to the size of 80 mm. before it is conveyed to the storage areas.
There are four roller mills utilized for raw meal production. The hot exhaust gas from each kiln preheater is used for the drying of raw materials. The gas-conditioning tower is used to cool down the hot gas before the raw mill circuit.
Raw Meal Silos
The continuous flow silos (CF silos) are used to homogenizing of raw meal. The total capacity of CF silos is 70,000 tons of raw meal.
The lignite / coal grinding and drying process take place in the vertical roller mill which utilizes the kiln exhaust gas as a heat source.
Being heated to a temperature of around 1,500 c in the rotary kilns, the raw feed is transformed to clinker by complex chemical reactions. The heating takes place in a series of suspension cyclone preheater.
The clinker cooling is performed in the grate cooler, which is an air quenching reciprocating grate cooler, to cool the temperature of clinker down to 100 c. There is one cooler for each Rotary Kiln.
Cement is manufactured by fine grinding the clinker together with various additives. There are a total of 4 Ball Mills for the cement grinding process. The Cement Mills utilize Roller Press as pre-grinders with additional Grit Separator for line 2. The total maximum grinding capacity is 7.2 million tons of cement per year.
Packing and Loading
There are two packing lines in Pukrang Plant. Ready to be shipped cement in bulk is stored in 8 cement silos with a total capacity of 100,000 tons.
