Compaction device for specific surface area measurement experiment

The utility model relates to the field of auxiliary equipment for testing the specific surface area of cement in a laboratory, in particular to a compaction device for testing the specific surface area of cement, which comprises a bottom plate, a cylinder and a rammer, the upper end of the bottom plate is fixedly connected with a vertical plate and a supporting cylinder, and the front end of the vertical plate is fixedly connected with a first transverse plate and a second transverse plate; the circumferential face of the sliding rod is connected with a balancing weight through a fastening assembly, and the cylinder is in sliding connection with the supporting cylinder. According to the utility model, the threaded rod is driven to rotate by rotating the handle, and the position of the limiting rod is changed under the action of the threaded rod, so that when a specific surface area experiment is carried out on a material, the ascending height of the balancing weight can be changed by adjusting the position of
