[0003] The existing calcium hydroxide fine powder screening device includes a material frame and a filter screen, wherein the material frame is connected with the filter screen. The existing device needs to be driven by manpower during operation, and a large amount of screening cannot be performed during screening due to the limited weight bearing capacity of a person.
