In china, the need of sand is over 10 billion tons .But there are many limits of the existing sand industry such as the keep increasing price, the high transportation cost, the uneven quality and the shortness of the natural sand while the lower quality, the excessive trash, the bad shape of the machine-made sand. Therefore, to meet the requirement of the wide market and to make up the disadvantage of the traditional technology , the VU aggregate optimization system of Liming Heavy Industry have emerged as the times require.

  This optimization system adopts the advanced technologies and scientific payoffs from domestic and abroad which will provide a brand new dry sand-making solution to the problem of exiting sand-making industry and will bring a new developmental chance for sand-making, cement-making, dry blend and ready-mixed concrete making industry.
  Taking the cheap and easy to get tailing, waste, construction waste, aggregate chips, and the small pebbles as the raw materials, the VU optimization system can produce the machine-made sand just like the natural sand with the dry environmental technology. The sand produced by the VU optimization widely used as the auxiliary sand of mixing plant, dry concrete, cement, aggregate quarry, and large –scale construction which can meet the huge needs of the sand market. With the enormous value of investment, the VU optimization system has been approved and welcomed by the customers
