Product Description
Clay brick Kiln Design coal fire brick Hoffman kiln
Raw material preparation
Before raw material being sent into raw material stock, masses of impurity and some organic parts will be eliminated by man power. In raw material stock, clay will be sent to box feeder by loader, and being sent to roller crusher and fine pulverizing grinder. Crushed clay with grain smaller than 3mm, and will be sent to double shaft mixer, water added and mixed, here the material moisture content reach to 13-14%. Thus the raw material is being sent to aging room by warehouse reversible belt conveyor.
Raw material aging process
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 in molding process. Box feeder with big stock capacity, which can guarantee the mixer extruder and extruding machine's feeding requirement, stabilize the green brick adobe moisture content and molding process. Meanwhile, this gives buffering time for multi-bucket excavator to change the working position. This also water down the synchronization requirement for former process. The aged material moisture content will reduce 1%.
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 1.5-2.0Mpa.
3) The hourly output per set is more than 8000pcs bricks.
Full automatic clay brick production line machine and brick making equipment
Drying and Firing
Drying and firing will adopt twice setting & firing process. Drying chamber adopts new type tunnel dryer with inner width of 2.4meter. Whole production line adopts 7 lines of double-rail tunnel dryers. The heating source is residual/waste heat from the tunnel kiln. The smoking air feeding temperature and air volume will be adjusted through the air-adjustment-system, so as to ensure the drying quality of green bricks. Well-dried green bricks will be unloaded from drying cart and re-stacking on the kiln cart manually.
Small brick dryer chamber for drying green bricks
Sintering bricks are produced by using clays as raw materials and adopting two-time setting and baking processes, that is Semi-stiff plastic extruding process; drying in the small section drying chamber using and baking in the Hoffman kiln process.
Main equipment has box feeder, primary roller crusher, fine pulverizing grinder, mixing and extruder, double stage vacuum extruding machine, double tunnel small section drying chamber, Hoffman kiln.
clay brick hoffman kiln
For this production line, raw material is clay with better material performance. So, the raw material be treated carefully by roll type crusher, fine pulverizing grinder, mix and extruder for guarantee the grain size distribution of the material and uniformity can meet the design requirement; This producing line adopts the semi-hard plasticity extruder to forming; double tunnel drying chamber to drying, hoffman kiln for firing. This technology is more concise, all adopt the mature technology, which also can meet the design requirement. The equipment selection of this producing line is reasonable, not only can guarantee the producing capacity, but also and guarantee the product's quality.
Dried bricks via the hydraulic ferry pusher are sent to the trail car. Then, the workers push the drying car onto the trail car, then send to the Hoffman kiln for unloading, stacking and firing.
Drying Chamber:
This design adopts small section drying chamber with flattop. It is with brick & concrete structure, with precast-concretetop plate, partition wall with thickness of 240mm, side wall with thickness of 490mm, top layer and insulating layer with thickness of 500mm.
The heat source of drying chamber is the waste heat from hoffman kiln, which will be supplied to each drying chambers through air channel by heat-supply blower from the chamber bottom. The drying chamber set up air-feeding system, moist-releasing system and testing system. Bottom layer bricks are ending-up setting method, so that to improve the drying efficiency and quality.
Hoffman kiln
This producing line adopts the new type hoffman kiln. This hoffman kiln have the impeccable firing system, exhausting system and afterheat system. It will produce the regular clay sintering bricks through adjusting all the systems and make the firing temperature more reasonable.
Hoffman kiln adopts the reinforced concrete foundation, the wall be built by the normal sintering brick, the fire hole and heat suction mouth be adopted the heat proof concrete.
