Jiangxi Building Materials Enterprise invested in a 600,000-ton limestone tailings resource utilization project. The project uses the advanced VU120 aggregate optimization system to provide the local construction market with high-quality machine-made sand products that meet national standards.

Project Overview

Raw material characteristics: limestone, tailings and melon stone with a particle size of 0-16mm

Design capacity: 100-120 tons per hour

Finished product application: mainly used in cement production and advanced concrete preparation

Core technology and process

Innovative advantages of VU aggregate optimization system Liming relies on a professional technical team to solve technical problems such as particle shape control and environmental dust removal in machine-made sand production. The system has the following significant features:

(1) Particle shape optimization technology:

Using waterfall self-grinding brush process

Low-energy crushing and shaping

Reduced porosity of finished sand

(2) Intelligent control system:

Adjustable range of fineness modulus

Powder content can be adjusted according to demand

Stable moisture content control

Environmentally friendly design: The project adopts a fully enclosed production process, equipped with a negative pressure dust removal system and an automatic humidification device to achieve dust concentration in the production process below the national standard limit.

Project implementation effect

Product quality:

The finished sand particles are round and reasonably graded, which can fully meet the preparation requirements of high-grade concrete.

Resource utilization efficiency:

Through the optimization process, efficient utilization of tailings resources is achieved, and the comprehensive utilization rate of raw materials exceeds 95%.

Environmental benefits:

Compared with the traditional wet process, it has obvious water-saving effect, no wastewater discharge problem, and high dust collection rate.

The successful implementation of this project has provided a feasible solution to the problem of shortage of natural sand resources. Its environmental protection concept and technological innovation have a positive role in promoting the transformation and upgrading of the building materials industry.
