Description

Technical Field

[0002] Calcium carbide is an important chemical raw material with a large production output. Unloading is usually done manually. Calcium carbide, the main component of calcium carbide, is a carcinogen. Long-term contact or inhalation can cause serious harm to the human body.

In order to ensure production efficiency, the calcium carbide pot is usually set larger, and manual unloading is not thorough, which is time-consuming and labor-intensive.
