Description

Technical Field

[0002] Lightweight plaster gypsum is a material used for indoor wall plastering. It is composed of an anti-cracking gypsum base, lightweight aggregates and additives. A stirring device is provided inside the lightweight plaster gypsum processing device. The stirring device will fully mix the anti-cracking gypsum base and the ingredients. The rotating motion of the stirrer can break up the anti-cracking gypsum base and the ingredients and make them evenly mixed.

[0003] According to a publicly disclosed lightweight plaster gypsum processing device (Announcement No.: CN221622605U), in the above application, the stirring rod is separated from the drive shaft by rotating the stirring rod, and the worn stirring rod is replaced separately. The stirring rod is repaired or replaced outside the mixing tank, and there is no need to go deep into the mixing tank for repair, thereby improving the safety of repair and simplifying the repair equipment.
