MANUFACTURED SAND WITH A DIFFERENCE!
The V7 System is the result of some remarkable research and development by Kotobuki Engineering & Manufacturing Co. Ltd. (KEMCO) in Japan, that adds a new dimension to the production of high quality, consistent aggregates for use in the construction industry.
Kemco's main object has been to improve the viability of manufactured sand, in the face of dwindling supplies from traditional sources such as land-based sand pits and dredging of marine and river deposits.
In these pages you will find an innovative solution ( Introductory Article) to the problems of making construction sand from quarried rock. Crusher dust, often a surplus quarry product, can now be turned into high quality sand of ideal grading and particle shape by the V7 Sand Manufacturing Plant.
