The only sand making equipment in the world that can economically produce manufactured sand from Calcium Carbonate crusher dust to use as a COMPLETE replacement for natural sand in concrete, while making a filler by-product that equates to the raw mill product for the cement making process (70% passing 75 microns).

V7 - The Difference

  • Calcium Carbonate makes excellent Kayasand, which sells for a premium in the Japanese market
  • Minimal marginal cost to extract additional Calcium Carbonate
  • Cement plants are commonly limited in output by the raw mill capacity
  • Calcium Carbonate filler is close to the raw mill product (about 90% passing 75 microns) and can bypass the mill
  • By feeding bigger feed to the V7, sand making reduces and more filler will be created
  • Calcium Carbonate Kayasand can be sold through the existing local cement sales network
