Polymer leaf disc filter is also
called disc filter element, used for high viscosity melt
filtration. The disc filter design maximizes the effective
filtration area per cubic meter, realizing the efficient utilization of space
and miniaturization of filtration devices. The main material is
stainless steel sintering felt or multilayer stainless steel sintered wire mesh.
Features: filter element bear the pressure
equably, stable filtration performance, can be repeatedly cleaned, long service
.
Polymer leaf disc filter is
divided into two kinds, according to the material is divided into: stainless
steel sintering felt, stainless steel sintered wire mesh; According
to the structure: hard and soft. Among the above types, stainless
steel sintered mesh filter material has the greatest advantages of high
strength and impact resistance, and sintered felt has the advantages of long
service cycle and good air permeability.

The Ultimate Guide to Milling in Road Construction
Road construction is a complex and meticulous process that demands precision at every stage to ensure the durability and safety of the final road. One of the most critical steps in this process is milling, a technique used to remove the top layer of existing pavement. This operation is carried out by specialized machines designed to prepare the surface for new asphalt layers effectively. In this article, we’ll explore everything you need to know about road milling, from its benefits and processes to how to choose the right **road milling machine** for your project.
**What is Milling in Road Construction?**
Milling, also known as cold planing, is a fundamental step in road construction where the top layer of old asphalt is removed. This method is essential for preparing the roadbed for new material, ensuring that the addition of new layers doesn’t increase the overall height of the pavement. By removing worn, damaged, or deteriorated asphalt, milling creates a smooth and even surface that allows new asphalt to bond properly. It not only prepares the road for resurfacing but also helps maintain the original structural integrity of the roadway.
**Advantages of Milling in Road Construction**
Milling offers numerous benefits that make it a preferred choice in modern road maintenance and reconstruction. Here are some of the key advantages:
- **Road Maintenance:** Regular milling helps eliminate cracks, ruts, and other surface imperfections that can lead to more serious structural problems if left unchecked. It plays a vital role in preventive maintenance, keeping roads safe and functional.
- **Correcting Surface Irregularities:** Milling ensures a level and even surface, which is crucial for the longevity and comfort of driving on the road.
- **Improving Skid Resistance:** By removing the smooth, polished top layer of asphalt, especially in wet conditions, milling enhances skid resistance and improves road safety.
- **Extending Roadway Life:** By allowing new asphalt to be laid over a stable base, milling significantly extends the lifespan of the road, making it more resilient to traffic and weather.
- **Cost Efficiency:** Milling is a cost-effective solution because it enables the reuse of old materials in new asphalt mixes, reducing waste and the need for new raw materials.
- **Recycling of Old Materials:** The process supports environmental sustainability by recycling the milled asphalt, which can be repurposed into new pavement. This reduces the demand for natural resources and minimizes environmental impact.
- **Time Efficiency:** Milling is a fast process that can cover large areas quickly, speeding up the rehabilitation of roads and minimizing traffic disruption.
**How is Milling Done?**
The milling process involves large **road milling machines** equipped with a rotating drum that grinds and removes the pavement. These machines can adjust their depth and width based on the specific needs of the project. Operators must carefully control the speed and drum rotation to ensure even surface removal and optimal performance of the machine.
**Key Factors to Consider When Buying a Road Milling Machine**
When selecting a road milling machine, there are several important factors to consider:
- **Width and Depth of Milling:** Choose a machine that matches the required specifications for your project’s size and depth.
- **Advanced Controls:** Look for machines with precise controls for depth, speed, and slope to ensure accurate results.
- **Durability:** Opt for a robust and well-built machine that can withstand the demanding conditions of road construction.
- **Ease of Operation:** Machines with user-friendly controls and ergonomic design improve operator comfort and productivity.
- **Maintenance Requirements:** Choose a model with easy-to-maintain components and accessible parts to reduce downtime.
- **Efficiency:** Consider fuel efficiency and environmental impact to lower operating costs and reduce the carbon footprint.
- **Versatility:** A versatile machine with interchangeable attachments can handle a variety of tasks, making it more adaptable to different projects.
