1.Material evaluation, project consultation design

In the initial stage of the construction of a sintered brick and tile enterprise, raw materials have an important influence on production process design parameters, product performance, drying chamber and roasting kiln structure design, and during the operation of the enterprise, raw materials have an important influence on the production cost control, energy saving, and environmental protection of the enterprise. Reaching the standards also has an important impact. Therefore, the judgment of the feasibility of raw materials is very important for the sintered brick and tile manufacturers.

The "Code for Design of Sintered Brick and Tile Factory" GB50701-2011 stipulates: "The design of a sintered brick and tile factory shall determine the product plan and process plan based on factors such as the quality of raw materials, reserves and process performance of raw materials." And in the quality requirements of raw materials: "Sintered brick and tile raw materials should be tested for mineral composition, physical properties and chemical composition, and comprehensively analyze and judge the feasibility of raw materials to make bricks and tiles, the suitability of the raw materials for the product, and the appropriate technology.

3. Operation management and production custody
a. A high-tech enterprise with independent legal personality.
b. Professional technical team.
c. Modern production management.
d. Low production cost.
e. High efficiency and high quality.
f. Ensure safe production and reduce employment risks.
g. The owner saves time, effort, and worry, and better develops the market.

4. Integrated use of natural resources

Advantages of Rotary tunnel kiln:
1. Low production cost:
a. Heat consumption: Less than 280 kcal/kg,For every 100 kcal/kg saved,Save 2 million yuan per year(Good kiln insulation, Superior thermal design, Full utilization of waste heat, Good kiln body sealing)

b. Electricity bill

c. Artificial:Rotary tunnel kiln:How many people are needed for a daily production of 300,000 folding standard bricks? need 28persons.

d. Equipment maintenance: Rotary  tunnel kiln does not require a kiln cart, save 300,000 RMB in maintenance cost of kiln car per year. Just clean the bottom of the kiln.

e. Land use cost.

2. High productivity&Low investment cost
Annual production capacity of 100 million pcs; Investment 15-20 million RMB; Reduce production costs by 15~25%.

3. Short construction period(Construction:Full research in the early stage to ensure fast, good and economical;Put into production:Personnel training, lifetime technical support from the expert team)
a. From the first month to the second month: Kiln factory production(Tailor-made design and modular production)
b. From the second month to the third month: On-site installation(Professional team construction)
c. From fourth month: Commissioning equipment(Professional debugging personnel)
d. From the first month to the  fourth month:On-site civil engineering and equipment installation()

4. Simple process flow-simple production management
Easy to manage: 1 raw materials--->2. Forming---> 3. Stacking----> 4. Drying---> 5. Firing:----> 6. Out of Kiln----> 7. Finished product.2s

5. Green environmentally friendly
a. Temperature monitoring during drying and roasting, humanized man-machine interface real-time data display to ensure that yield rate is over 99.6%.
b. Assembled structure, the kiln system can be disassembled and reinstalled in different places. 
c. The exhaust gas is more environmentally friendly after centralized treatment.
d. Low energy consumption so low carbon emissions.

a. Environmental protection standards
b. Production capacity reaches the design target
c. The yield of drying and roasting is over 96%.
d. Rotary tunnel kiln has not been overhauled for 10 years.
e. The internal reference heat consumption is less than 300 kcal/kg
 

1. Flue gas desulfurization(To desulfurize, the flue gas must be concentrated before processing,  After the exhaust gas is concentrated, it must be transported into professional desulfurization equipment, the desulfurization capacity of the desulfurization equipment must be matched with the production capacity)?

Solution:From 2008 to 2012, horizontal desulfurization on kiln roof; 2012 Annular flue centralized desulfurization process.

2.Kiln life issues(How many years can the Rotary tunnel kiln be used) ?

Solution:No major repairs in ten years!

3.Short production cycle in alpine regions?

Solution: In fact, the production cycle is not short! why? Because the tunnel kiln is indoors. The mobile tunnel kiln can also be placed indoors! So this is not a problem at all!

4.The range of raw materials is relatively narrow(One-time code burning, Artificial drying,Straight tunnel kiln)?

Solution:Although the kiln design has 138 meters, 150 meters, 168 meters and other different kiln length designs for different characteristics of raw materials, and has designed double drying chambers. But it still cannot cover all the raw materials.Inappropriate raw materials, Xi'an Liyuan can only say sorry! Seek truth from the facts-don't do the unsuitable raw materials if they can't be done, so as not to mislead others!

5.The shape of the venue is demanding?
Solution: Compared with the tunnel kiln, this is indeed the case! Although we have introduced different kiln diameters with diameters of 90 meters, 100 meters, 125 meters, and 150 meters, the fact that the layout flexibility is not as good as that of ordinary tunnel kilns cannot be changed.Therefore, I can only say sorry for the requirement of building a factory in a long and narrow terrain.
