Cement manufacturing - brief description of a cement mill. Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds.

Polishing Process The process begins with the use of coarse diamond segments bonded in a metallic matrix. These segments are coarse enough to remove minor pits, blemishes, stains, or light coatings from the floor in preparation for final smoothing. Depending on the condition of the concrete, this initial rough grinding is generally a three- to four-step process.
Spray some reactive concrete hardener onto the concrete to encourage a shiny look. Step 5 Switch to 120-Grit. Place a 120-grit pad onto the concrete machine for a thorough grinding process. This should level off the surface completely. Begin at one end of the patio and carefully spray some stain over the entire surface to color the concrete.
