Jun 17, 2019· Improvingparticle size distributionincement production. Enhancingcement grinding efficiencyis beneficial for numerous reasons: Lower energy costs. An improvement ingrinding efficiencymeans increased fineness at constant kWh/t or, more typically, lower kWh/t for constant fineness. Increased mill production.
Introduction The particle size of Class G oilwell cement is responsible for its limiteduse in specific remedial cementing operations. Because the largest particles ina typical Class G cement are in the 100- to 150- range, cement slurries willnot penetrate fractures narrower than about 0.4 mm or sandpacks finer thanabout 10/20 mesh.

In general, these raw materials arrive from the quarry, at the beginning of the process ofsizereduction in pieces of up to 2 meters in its largest dimension. To burn a good quality clinker in acementkiln, these lumps should be reduced to aparticle sizeof approximately 0.05 mm.
Assessingcementfineness. In the past,cementproducers gaugedcementfineness (i.e.,cement particle size) by evaluating the specific surface area (SSA) or Blaine fineness and the sieve residue at various sizes. However, many producers now useparticle sizeanalysis techniques to assess fineness and help monitor the efficiency of themill.
