[0002] Calcium oxide is an inorganic compound with the chemical formula of CaO, commonly known as quicklime. Calcium oxide is mainly processed by limestone calcination method. The process is as follows: the limestone is coarsely crushed to 150mm, and fine slag below 30-50mm is screened out. The particle size of anthracite or coke is required to be below 50mm, and the low-melting point ash contained therein should not be too much. The amount of anthracite or coke added is 7.5%-8.5% (weight) of the limestone. The screened limestone and fuel are added into the kiln from the top of the kiln at a fixed time and quantity, calcined at 900-1200℃, and then cooled to obtain the finished product.

[0003] At present, most of the vibrating screens for calcium oxide processing are open structures with poor sealing performance, resulting in a large amount of dust floating during the screening process, leading to environmental pollution.
