石膏砂浆是以半水石膏作为胶凝材料，添加干砂或玻化微珠作为填料，辅以各种功能性添加剂混合而成。主材种类简单，添加剂计量和分散均匀性要求高。玻化微珠计量采用体积和重量双计量，添加剂采用地面称重和喷入式添加。

Gypsum mortar is made of hemihydrate gypsum as cementing material, with dry sand or glass bubbles as fillers, supplemented by various functional additives.The main material type is simple, the additive measurement and dispersion uniformity requirements are high.Glass beads are measured by volume and weight, and additives are added by ground weighing and injection.

由加料斗、斗式提升机、卧式无重力搅拌机、成品仓、自动称量包装机、电控箱、除尘器组成，主机置于平台之上。物料由斗式提升至搅拌机进行混合，混合时间大概3-5分钟（根据物料不同时间会有差异）。

It is composed of adding hopper, bucket elevator, horizontal agitator without gravity, finished product warehouse, automatic weighing packaging machine, electric control box and dust collector. The main engine is placed on the platform.The material is lifted from the bucket to the mixer for mixing, and the mixing time is about 3-5 minutes (depending on the time of the material).
