Low yield rate? Poor particle shape? This intelligent device from Tietuo has revolutionized the sand and gravel production industry!

"Shortage of sand and gravel" has become a frequently mentioned keyword in the infrastructure construction craze in recent years. With the depletion of natural sand resources and the tightening of environmental protection policies, the drawbacks of traditional sand-making methods have become increasingly prominent. Against this backdrop, how the new generation of sand-making technology can transform from "extensive production" to "green intelligent manufacturing", while achieving controllable sand and gravel quality and a leap in production capacity, has become a continuous research topic for equipment manufacturers.

Based on the industry development trend and customer demands, Tietuo Machinery, relying on its strong R&D capabilities, has built a full life-cycle technical solution covering raw material sand making and shaping, mixed material stirring to the recycling and utilization of waste materials. Its independently developed VS series sand-making equipment has solved the pain points of the industry with revolutionary innovation.

Breakthrough in core technology

The VS series sand-making equipment adopts the internationally leading "V-shaped air selection + dynamic powder selection" dry sand-making process, and is specially designed for the production of high-quality machine-made sand required for high-performance concrete. This device achieves full-process intelligent control through three innovative modules:

1. Intelligent crushing module

The vertical shaft impact crusher adopts an integrated shell structure, which improves its operational stability by 30%

The 5-channel rotor design enables central feeding, with a maximum feed particle size of up to 60mm, optimizing the particle shape by 50% and reducing the content of needle and flake particles to less than 10%

The energy conversion efficiency reached 92%, and the sand-making rate increased by 25% year-on-year

2. Precision sorting system

V-shaped air separation device

Fine sand and coarse aggregates are separated through three-stage gradient air separation. While increasing production capacity by 40%, the service life of the screen mesh has been extended by more than three times.

Dynamic powder selection module

Real-time adjustment of rotor speed (adjustable from 100 to 200rpm), precise classification of particle size from 0.075 to 4.75mm. The powder content control accuracy reaches ±0.5%, and the fineness modulus deviation is ≤0.2

3. High-efficiency screening system

Innovative application of Three-axis Elliptical Vibrating screen

Modular design reduces maintenance time by 60%

Dual-motor drive reduces energy consumption by 35%

The screening efficiency reaches over 92%, quality verification data

Certified by the National Building Materials Testing Center, the high-quality machine-made sand produced by VS equipment:

The particle shape index (roundness coefficient) is ≥0.75

The gradation continuity meets the standards of Zone II

The crushing index is ≤18%

The methylene blue value (MB) is ≤1.0

Tietuo Machinery redefines the standards of the sand-making industry with "full-process environmental protection, intelligent production, and customized services". Choosing the VS series equipment not only means obtaining a high-quality sand and gravel production line with an annual output of over one million tons, but also serves as the smart key to unlocking the future of green infrastructure. The moment the start button is pressed, you will witness that every grain of sand and gravel carries the essence of intelligent manufacturing, and every production line becomes an ecological unit for sustainable development.
