In today’s social economy, highways are a modern road transport channel that plays a vital role in economic development. Facts have proved that highways as infrastructure construction have played an active role in promoting resource development, logistics, industrial structure adjustment, investment attraction, and horizontal economic integration along the route.

Introduction to highway mineral powder:

Highway construction cannot be separated from a large amount of concrete support, and adding other materials instead of cement in concrete materials can produce new concrete with better performance, lower energy consumption and less environmental pollution. High-performance concrete of mineral powder is a kind of green new concrete. It uses limestone powder, industrial waste residue, blast furnace slag and other materials. After grinding to a certain fineness, it can replace cement in a large amount (usually up to 30%-70% of the cement dosage). Mixing into concrete can not only adjust the performance of concrete, but also effectively reduce costs and achieve comprehensive utilization of resources. It is a green building material that is both sustainable and economically viable.

Highway mineral powder effect:

The main chemical components of the ore powder are CaO, SiO2, l2O3, Fe2O3 etc. The main functions in the concrete are: reducing the amount of cement, improving the workability of the concrete, reducing the heat of hydration, increasing the strength of the later stage, and improving the internal structure of the concrete, improving impermeability and corrosion resistance. Concrete mixed with fine mineral powder can delay the hydration speed of the cementitious material and prolong the concrete setting time. This property is beneficial to the concrete transportation and construction in the high temperature season.

Grinding equipment

HD series Raymond Mill

【single machine output】1-60T/H

【Outstanding advantages】

Special grinding device, automated electronic control system

1.Product quality is stable

The product has a short residence time in the grinding mill, which is easy to detect and control the particle size and chemical composition of the product, reduce repeated grinding and stabilize product quality.

2.High drying efficiency

The hot air that enters the grinding mill from the outside can be contacted with materials many times and fully, and the drying ability is strong, which not only saves energy, but also meets the requirements of different humidity materials.

3.Low operating costs

The grinding roller directly crushes the ground material on the grinding disc, and the energy consumption is low; the grinding roller and the grinding disc are not in direct contact during the working, and the grinding roller and the lining plate are made of good quality materials, and the service life is long and the wear is small.

4.Environmentally friendly cleaning

The vibration is small, the noise is low, and the equipment is completely sealed. The system works under negative pressure, no dust overflows, and the environment is clean, meeting the national environmental protection requirements.

5.The fineness of the finished powder is uniform, and the screening rate can reach over 97%.
