The lime kiln with a daily output of 200 tons is one of the most used lime kiln equipments at present. There are two kinds of calcination processes for a daily output of 200 tons lime kiln. One is mixed-burning lime kiln with a daily output of 200 tons, the other is gas-burning lime kiln with a daily output of 200 tons. Now that we want to know about the daily production of 200 tons lime kiln, we will comprehensively analyze the advantages and disadvantages of the daily production of 200 tons lime kiln with you today.
Production line of 200 tons mixed-firing lime kiln per day: Fuel and material are mixed together by corresponding proportions, mixed on conveyor belt by measuring scale, and then entered into the feeding trolley of inclined lime kiln hoist. The feeding trolley is pulled up uniformly by hoister. In order to prevent uneven discharge or spilling of feeding trolley, most of the 200 tons mixed-material lime kiln roofs are now produced daily. The end is equipped with mixing chute and automatic distributor, which can not only solve the above problems perfectly, but also avoid the effect of kiln wall by distributing materials scientifically through distributors. The interior of limestone kiln is divided into pre-tropical zone, firing zone and cooling zone. Limestone and coal fuel first enter the pre-tropical zone, which can increase from room temperature to 600-800 degrees Celsius. Such problems can lead to the conclusion of limestone and coal. Crystal water and magazines are removed, and then the calcination effect will be better. When the temperature reaches 1250 degrees Celsius, the limestone is basically completely decomposed, leaving behind lime. The high temperature lime can not be directly brought into the warehouse through conveyor, so the problem of lime after heat transfer of cold air and hot materials through cooling belt is not more than 60 degrees Celsius. It ensures that the heat of the lime kiln is not lost and avoids the fire caused by high temperature lime.
Production line of 200 tons gas-fired lime kiln per day: Standard limestone particles enter conveyor belt from feeder, conveyor belt operation directly puts raw materials into the car of inclined hoist, lifts from hoist operation to the top of lime kiln, also has chute and automatic distributor, but the fuel of 200 tons gas-fired lime kiln per day uses natural gas, and natural gas pipeline from lime kiln cylinder. The lower part of the middle part enters the natural gas combustion system from the kiln body, but the use of natural gas fuel calcination technology requires a lime kiln with a daily production of about 200 tons. If the diameter of the lime kiln is too large, the natural gas can not be calcined evenly. The production problem is also the research direction of the gas-fired lime kiln at present. The gas-fired lime kiln with a daily production of 200 tons is different from the mixed-fired lime kiln only in feeding and combustion system. Other equipment and processes are basically the same.
