1. Lime powder in the pot is no problem, if you encounter water will overflow, so you must pay attention to waterproof problems.
2. Unknown_Error
3. The clarified lime water is the aqueous solution of hydrated lime (i.e. calcium hydroxide). The hydrated lime reacts with water to proce hydrated lime, and the hydrated lime dissolves in water to obtain the clarified lime water. Because the solubility of calcium hydroxide in water is relatively small, the hydrated lime is filtered after adding water, and the filtrate is clear lime water.
4. The conditions of CaO + CO2 = CaCO3: high temperature
Ca (OH) 2 + CO2 = CaCO3 + H2O
3 prove that: put quicklime into water, filter out insoluble matter, add enough HCl to insoluble matter, if there is any gas that can make clear lime water turbid, It is proved that there is calcined limestone in quicklime
CaCO3 + 2HCl = CaCl2 + H2O + CO2 ↑
Na2CO3. 552g / cm3. The melting point is 851 ℃. It tastes astringent. It is soluble in water, especially in hot water. The aqueous solution is strongly alkaline. Slightly soluble in anhydrous ethanol, insoluble in acetone. It can neutralize with acids to form salts and decompose with many salts. In the air can graally absorb water and carbon dioxide, generate sodium bicarbonate and form a hard decision, rece the quality
the application field is a kind of basic chemical raw material, which has a wide range of uses. The chemical instry is used to proce sodium hydroxide, foamed alkali, sodium bicarbonate, sodium alum, sodium yellow blood salt, sodium pyrosulfite, sodium sodium cyanide and other chemical procts. Soap can be made by adding fatty acids. It can also be used as additive in civil alkali, synthetic detergent and raw material for proction of sodium tripolyphosphate. It is an important alkaline melting agent for the proction of bottle glass, flat glass, bulb, thermos and daily enamel pigment. It is also a hydrochloric acid neutralizer for the proction of monosodium glutamate and chemical soy sauce. Wool spinning, cotton and hemp instry is used to wash wool, which can make sheep fingers into milk, dissolve sheep sweat, remove impurities in wool, and remove st.

5. The best way is to use bag filter. Bag filter is to use negative pressure ventilation to treat the st at the outlet of your lime kiln. If you use the shower method, it will cause secondary pollution. You can decide which one to choose according to the needs of your company.
if you only use it when you ship every day, it's very simple. Just turn off the st collector when you don't ship, and it won't waste your electricity

6. In the process of grinding operation, there are certain technical elements for grinding process, such as particle size of grinding materials, cement, temperature, etc., which are the basis for selecting grinding process, grinding equipment and management. Here, the Red Star Machinery mill into the grinding of the particle size of the material
the particle size of the feed has a great influence on the output, quality and power consumption of the ball mill. The particle size is small. If the feed is even, it is easy to grind, the output and quality of the mill are high, and the power consumption is low. contrary. Due to the large particle size and uneven feed, grinding is difficult, the output and quality of the mill are low, and the power consumption is also large. Therefore, the smaller the particle size of the feed material is, the more favorable it is to improve the output and quality index of the mill. However, recing the particle size of the feed material will be limited by the conditions of the grinding equipment
in large and medium-sized cement plants, it is difficult to crush a large amount of limestone to a very small particle size (such as less than 10 mm) under the current equipment conditions. Now the grinding particle size of different materials can only be controlled in the following range:
clinker, less than 30 mm
limestone, less than 25 mm
gypsum, less than 50 mm
mixture, less than 30mm
for the mill whose inner diameter of the mill cylinder is less than 1.5m, e to the small size and impact capacity of the grinding body, the particle size of the feed material should be controlled below 10 ~ 15mm.

7. This is the instability of lime. After absorbing water and air oxidation, lime forms a part of soluble calcium salt. After this moisture regain, calcium salt begins to precipitate and condense on the surface and cracks, which destroys the original coating structure and causes falling off. The treatment method is to remove the damaged lime layer, use putty powder, if the environment is humid, you can consider the external wall putty or Lafarge as the base
8. An index for characterizing the hydration reaction rate of quicklime is expressed as the milliliter of 4mol / L hydrochloric acid consumed by neutralizing Ca (OH) 2 proced ring the digestion of quicklime in sufficient time.
9. The lime kiln wants to shake out the ash, how to put out the army must use the sieve
