The grid type grinding machine has a grid plate at the discharge end, and the grid plate has a plurality of small holes for discharging the slurry. A slurry lifting device is installed, which is a radial rib that divides the space between the lattice plate and the end cap into a plurality of fan-shaped chambers leading to the hollow journal. When the mill rotates, the radial ribs act to lift the slurry, and the slurry discharged from the small holes in the grid plate is lifted to the hollow shaft of the mine, and discharged from the mill through the hollow journal, so the work of the machine The main features are forced discharge and high production capacity. A sealant is a substance used to stop fluids from passing through a seam or opening in a surface or material and is a type of mechanical seal. In building construction, sealants are sometimes synonymous with caulking and are also used to block the transfer of dust, sound and heat. Sealants can be weak or strong, flexible or rigid or temporary. Sealants are not adhesives, but some have adhesive properties and are called adhesive sealants or structural sealants.
A caulk sealant has three basic functions: it fills the gaps between two or more substrates; it forms a barrier through the physical properties of the sealant itself and its adhesion to the substrates. And it maintains hermetic properties over the life expectancy, usage conditions and environment. Sealants perform these functions through the correct formulation to achieve specific application and performance characteristics. However, aside from adhesives, there are few other functions that can replace the sealing process.

Although not very strong, sealants have many properties. They seal the top structure to the substrate and are particularly effective during waterproofing by keeping moisture out of (or in) the components that use them. They provide thermal and acoustic insulation and can be used as a fire barrier. They may also have electrical properties. Sealant can also be used for simple smoothing or filling. They are usually required to perform several of these functions at a time.
