In highway construction, high-quality mineral powder serves as a key additive to asphalt mixtures. The choice of processing equipment directly impacts project quality and production efficiency. With technological advancements, vertical grinding mills, with their high efficiency, energy saving, intelligent environmental protection, and stable and reliable performance, have become ideal equipment for highway mineral powder processing. This article will delve into the core features of vertical grinding mills and their application value in highway mineral powder production.

The core advantages of vertical grinding mill

1. High efficiency and low energy consumption

The vertical grinding mill utilizes a vertical mill structure and multi-stage sorting technology, enabling a single unit to produce 5-200 tons per hour while reducing power consumption by 30%. Its optimized process flow and efficient grinding system significantly shorten processing cycles, lower production costs, and meet the volume demands of large-scale highway projects.

2. Precise granularity control to meet various needs

The equipment’s finished product fineness can be freely adjusted between 80-600 mesh, resulting in uniform and highly active powder output, perfectly suited to the mix requirements of different grades of asphalt concrete. Through an intelligent grading system, the particle size distribution can be narrowed, improving the filling effect and mechanical properties of the mineral powder.

3. Intelligent environmental protection, green production

Equipped with a fully sealed structure and pulse dust removal system, dust emissions are below 10mg/m³, far exceeding national environmental standards. The PLC intelligent control system enables “one-button start and stop,” fault warnings, and remote monitoring, reducing manual intervention and lowering operation and maintenance costs, creating a clean, dust-free workshop.

4. Wear-resistant and durable, long-term stable operation

Core components (such as grinding rollers and grinding discs) are made of imported wear-resistant materials such as high-chromium alloy, extending their service life by more than 2 times and reducing equipment failure rates by 60%. The manufacturer provides 24-hour after-sales response and full lifecycle technical support to ensure the continued efficient operation of the equipment.

5. Multifunctional adaptation to expand industry value

In addition to highway mineral powder (such as limestone and basalt), vertical grinding mills can be widely used in cement, metallurgy, electric power and other fields, supporting enterprises to expand their business territory and realize deep processing and resource utilization of mineral powder.

Application scenarios in highway mineral powder processing

1. Asphalt mixture optimization

High-fineness mineral powder processed by a vertical grinding mill can improve the adhesion, durability, and rutting resistance of asphalt concrete. In particular, ultrafine powder with a D97 of 8.5μm directly enhances the density and service life of pavement materials.

2. Balancing environmental protection and economic efficiency

The low energy consumption of the equipment reduces energy consumption, which is in line with the “dual carbon” goals; while the high yield and automated production reduce labor and maintenance costs, creating significant economic benefits for the enterprise.

3. Intelligent production upgrade

PLC control of the entire process from raw material feeding to finished product packaging, as well as real-time data monitoring and adjustment, helps enterprises achieve digital and intelligent transformation and improve production management.

Why choose vertical grinding mill?

● Advanced technology: It integrates crushing, drying, grinding and grading, simplifies the process flow and saves land and infrastructure costs.

● Quality assurance: The automatic slag discharge function removes impurities, increases the content of effective ingredients such as calcium oxide, and ensures the purity and stability of the finished product.

● Market recognition: Branded equipment such as Guilin Mining Machinery has been verified for its stability and powder output quality in domestic and international highway projects and has been widely recognized by the industry.
