Calcium carbide production process
Thread Content
Dear engineers, those of you who have in-depth knowledge of the calcium carbide production process, I have some questions I’d like to ask. First question: Are the raw materials used in calcium carbide production, namely carbon and quicklime, in powder form?
The raw materials that arrive are in block form; after processing, they are turned into powder, and the calcium carbide produced is also in block form
What is the transportation process for powder? Is it pneumatic conveying? Is it still belt transmission? Is it necessary to monitor the powder flow rate and moisture content as well? Is it necessary to strictly follow the ratio when reacting with calcium oxide? Is there bag dust collection involved?
The small pieces are melted at high temperature directly inside the equipment; bag filtration is available
The production of calcium carbide requires that all raw materials be in lump form; through high-temperature reactions in a furnace, they are converted into molten calcium carbide, which is then cooled back to a lump form

I heard that calcium carbide cannot get wet, so is it necessary to check for moisture when storing calcium carbide?
There are no such strict requirements. . . Ensure proper moisture prevention, keep the calcium carbide storage area dry and well-ventilated; the height of windbreak walls should be appropriate, the stacking of calcium carbide should not be too crowded, and the stacking height should be suitable. Part of the surface of calcium carbide will weather, but by taking the above measures, weathering can be reduced.
Okay, thank you. Thanks for your advice. I was wondering if it would be possible to add you on QQ or use some other means of communication, as it would be easier for me to ask further questions
Calcium carbide is produced in closed calcium carbide furnaces, and the particle size of the raw materials must meet certain requirements. Excessive powder content can result in poor air permeability of the furnace charge, leading to caking and material collapse, and thereby causing a range of problems.
Thank you; what you said is very valuable
