Does your sieve frequently break down due to worn-out screens? Polyurethane screens can significantly extend the lifespan of your equipment due to their resistance to aggressive environments. In this article, we explore how polyurethane screens for sieves can impact your production efficiency, reduce maintenance costs, and improve product quality.
Why Polyurethane is Better than Metal and Rubber
Polyurethane is 10 times more wear-resistant than rubber and surpasses metal in corrosion resistance, making it ideal for screens in the mining industry. This material is not susceptible to corrosion and withstands extreme temperatures from -60 to +100 °C. Polyurethane ensures a longer lifespan due to its resistance to abrasive wear, which is particularly important for parts constantly in contact with hard particles.
| Parameters | Rubber | Metal | Polyurethane |
|---|---|---|---|
| Wear Resistance | Low | Medium | High |
| Operating Temperature | Limited | Wide | Wide |
| Repairability | Difficult | Difficult | Easy |
| Weight | Light | Heavy | Light |
Polyurethane is not only durable but also easy to install. Thanks to free casting technology, polyurethane screens are manufactured with precise cells, ensuring better sorting capability and less contamination.
Which Parts and Assemblies to Replace
Replacing metal sieve parts with polyurethane ones can significantly reduce repair frequency and increase continuous operation time. Key assemblies to replace include screens, linings, and rollers. Polyurethane screens are made using the free casting method, allowing for the creation of assembly sections that can be easily replaced without dismantling the entire screen. This reduces maintenance costs and ensures prolonged equipment operation.
Installing polyurethane screens does not require special tools: they are easily mounted on the sieve frame using standard fasteners. Using polyurethane linings and rollers also helps reduce friction and contamination, which is a crucial factor in the mining industry.
Impact on the Enterprise
Installing polyurethane screens reduces repair costs and equipment downtime, increasing overall production efficiency. The precision of polyurethane screen cells improves material sorting, positively affecting the quality of the final product. Replacing metal screens with polyurethane ones also reduces noise levels in workshops, improving working conditions for staff.
Engineer Tip: Replacing metal screens with polyurethane ones reduces noise levels in the workshop, improving working conditions for your staff.
The efficiency of polyurethane screens also lies in their ability to reduce equipment energy consumption due to their lighter weight, which is an additional advantage for enterprises aiming to reduce production costs.
How to Choose Screen Hardness and Configuration
The choice of polyurethane hardness depends on operating conditions. For the mining industry, polyurethane with a hardness of about 70 Shore D is typically chosen for maximum wear protection. The configuration of the holes also plays an important role: for more precise sorting, choose screens with conical cells and bridges between perforations to prevent material sticking.
Polyurethane screens can be manufactured in various sizes and configurations, allowing them to be adapted to the specific requirements of your production. The right choice of hardness and configuration not only enhances efficiency but also reduces maintenance costs.
Polyurethane Screens in Sieve Assemblies
In sieve assemblies, polyurethane screens play a key role. They are installed on both central and edge sections of the sieve, ensuring even material distribution. Thanks to their high strength and flexibility, polyurethane screens can withstand heavy loads during ore and other material sorting. This reduces the risk of damage to other parts of the sieve and decreases the need for frequent repairs.
The installation process of polyurethane screens involves using standard fasteners, significantly simplifying their installation and replacement. This allows for quick adaptation of the sieve to changing working conditions without significant time and resource costs.
