Description

Technical Field

[0001] The utility model relates to the technical field of lime production screening devices, in particular to a screening device for granular lime production. Background Art

[0002] White lime is a general term for quicklime and slaked lime. Its main components are calcium oxide (CaO) and magnesium oxide (MgO). The dissolution of quicklime is an important part of construction mixing. The process must be effectively controlled during specific construction. During production, because the granular white lime contains more impurities, it needs to be screened during production, so a screening device is required.

[0003] The existing screening device for granular lime production screens the lime through the sieve holes on the screening plate during use. During the screening process, since the specifications of the sieve holes on the screening plate are fixed, it can only screen the lime particles of the same specification. When particles of different specifications need to be screened, the corresponding screening plate needs to be selected, which leads to high limitations of the device and low applicability. Therefore, a screening device for granular lime production is urgently needed to solve the above problems. Utility Model Content
