Saying goodbye to the weaknesses of traditional machine-made sand; Overcoming the standards of GB/T14684 and JGJ52

Designed, manufactured and installed by us, this VU120 machine-made sand production line in Shijiazhuang was put into use in February, 2015. Its establishment plays an important role in relieving shortage of natural sand, protecting environment and developing green building materials and green mines.

Project Profile

Scheme design--installation and commissioning

The use of highly-intensive fully-closed tower-like layout integrates the high-efficiency sand-making system, particle shape optimization, stone powder control, grading adjustment, water content control and environmental protection, which can optimize and adjust the indexes like the particle shape, grading, powder content and fineness modulus so that machine-made sand can completely replace natural sand in concrete and mortar preparation. The performance of machine-made sand gets improved and the cement and the cement and additives can be saved a lot.

Performance Standard

The sand produced by VU meets the standards of GB/T14684 and JGJ52. The sand can be adjusted according to the practical requirements. The fineness modulus can be controlled within 2.0-3.5; the powder content 3-15%.

Equipment in the Production Line

Based on over 30-year experience in this industry, we spent 5 years developing VU system at the specialized aggregate optimization test site to satisfy the increasing demand for high quality sand and the performance requirement of concrete and mortar. VU Aggregate Optimization System is a scheme system designed to produce high quality machine-made sand which overcomes the problems in the sand-making technology including crushing, grinding and separating. In this production line, VU Aggregate Optimization System perfectly met all the machine-made sand production standards of Shijiazhuang Hengxin Jinshuo Construction Material Company.

Technology Analysis

After being crushed and shaped by the VU Sand-making Crusher, the tailings below 10mm as raw materials are divided into three components under the action of FM Control Screen and Dust Collector--- stone powder, reverting material and finished sand product. Stone powder is collected by Dust Collector and stored at the fine ore bin while the finished sand product enters the Particle Shape Optimization Machine for further dressing and then is taken the last processing step--- mixing in humid environment. Processed by VU Aggregate Optimization System, raw materials can be turned into high-quality sand with reasonable grading, smooth shape and controllable powder content, and dry, clean, recycled and high-quality stone powder (Application fields depend on raw materials).
