Best Chamber Dryer Tunnel Kiln Brick Factory for India
Technological Description
Technical key point
A. The material should be fully mixed when processing, thus to ensure the good molding of the green brick and drying uniformity.
B. The clay material should be proper treated, the biggest particles should be around 2mm or so.
C. Molding moisture content should be controlled under 18%. The section before critical point while drying must be strictly controlled and drying cycle is not less than 26 hours.
This production line has advanced technology, reasonable process equipment selection and high mechanization degree; It can not only meet the production requirement, but also ensure good products quality. It can product a variety of products at the same time.
Raw material crushing
In raw material stock, clay will be sent to box feeder by loader, and being sent to wet pan mill and fine pulverizing grinder to be crushed. Crushed clay will be sent to double shaft mixer, water added automatically and mixed. Thus the raw material is being sent to aging room by warehouse reversible belt conveyor.
Raw Material Aging Treatment
Material will be aged in the aging room, thus, water inside will be diffused and evenly divided, the grains will be further dissolved, tempered and plasticized so that the shaping performance will be greatly improved. Aged material will be unloaded on belt conveyor by multi-bucket excavator, then being sent to box feeder for molding process.
Molding process
Aged clay material first will be sent to mixing extruder for water replenishing and mixing, then the double stage vacuum extruder will squeeze material to clean-surface and solid-inside columns, which will be cut into the required adobes by cutter.
Extruding machine is the key equipment among the whole production line, its performance are required as follows:
1) They can meet the need of different specification and hole shapes of the brick
2) The vacuum degree is -0.092Mpa, the extruding pressure is 2.0-3.0Mpa.
3) The hourly output per set is more than 10000pcs Chinese standard bricks.
2.5 Brick cutting, stacking and transportation system
The whole system is used to automatically loaded green bricks on the pallet and bricks will be sent into the tunnel drying room for drying by drying cart or ferry cart, then dried bricks will be unloaded from the drying cart and pallet automatically, then sent into the automatic setting process. After unloading, empty pallet will be sent to the plate storage from storage and transportation line. A complete set of system is full automatic operation.
Drying and firing
Drying and firing will adopt two times stacking & firing process with single layer drying technology. Drying chamber adopts tunnel dryer (83.65x22.625m). The heat of the dryer comes from high temperature heat of fired-products and residual heat from Tunnel Kiln, through change the system to adjust the feeding air temperature and volume, so that to ensure the drying quality of green bricks.
Tunnel kiln adopts large section with inner width of 6.6 meter, it is designed as a flat ceiling structure. This kiln is suitable for firing products with 1200KJ/Kg characteristics.
Tunnel kiln has smoke exhausting system, kiln cart heat releasing system, kiln cart cooling system, gas burning system, heat recovery system, rapid cooling system and back pressure system(pressure balancing system). This kiln has following features: Large section, high capacity, small section temperature difference low, good heat maintain. Meanwhile, the kiln auto-control system can ensure the baking heat parameters are stable, so to guarantee the brick firing quality is good...
