2. Productive Technology
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 under the sun 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, Hoffman kiln.
3. The fuel coal is calculated on the basis of 5000x4.18 Kilo Joule / Kg.
4. The water consumption includes non-production (living) requirement.

7. 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.
The 30% heat source of hoffman kiln come from internal combustion, 70% come from out injection.

9. Civil work
Basic requirement for the field
Factory can not build in caving zone or fracture zone. Factory should be above 300 meters apart from residential area and on downwind position, because in mass production process, a few noise and dust will be produced.
10. Layout principle
On the premise of meeting the requirement for the production technology, try to make the layout compaction, with short transportation line, transportation easy and smooth, passengers and goods transportation separate and not disturb each other. It accord with the demands of clean, fire proofing and safe etc. with green planting arrangement and environment protection, so that to make economic and reasonable layout and practical total graphic design. This should make good use of the landform, if necessary make the layout in vertical direction, so that to reduce the ground works.
11. Construction engineering sub-item
Raw Materials Processing: (square meter): 48.2X18=867.6m2
Shack of hoffman kiln:29X122=3538M2
Total: 4405.6m2
Factory area will be not less than12,000 square meters.
12. Electric power
Facilities normal power matched is 380V, 50HZ, Four-wire three-phase alternation current. (can adjust according to local requirement.)
