TECHNICAL FIELD
[0001] The present application relates to the technical field of sand and gravel screening, and particularly relates to a raw material screening device for putty powder production. BACKGROUND
[0002] Putty powder (also known as filling putty and wall putty) is a building material used for repairing and painting walls. It is commonly used to fill small holes, cracks and uneven places on walls and other surfaces to ensure a smooth surface and provide a good base for subsequent paint coating. A large amount of sand and other raw materials are required in its production process. The particle size of these raw materials directly affects the quality and application effect of putty powder. Especially in the production of different specifications of putty powder, the particle size of sand is different, so the screening of sand becomes a key link in the production process. The commonly used sand screening device in putty powder production is mostly a roller screening device. The roller screening device realizes the screening of sand particles through a rotating roller screen, and different particle sizes of sand are separated by using different screen aperture sizes.
[0003] However, the existing roller screening device has the problem that sand particles are often stuck in the screen holes of the roller filter screen during the screening process, and the sand particles often accumulate on one side of the roller filter screen during the screening process, causing too much material on one side of the screen and too little material on the other side. The uneven screening effect causes these particles to be unable to pass through the screen in time, resulting in low screening efficiency. SUMMARY
