In the bulk material handling industries such as mining, metallurgy, and power generation, silo blockage and chute wear are two long-standing problems plaguing production, resulting in high costs and personal safety. Traditional metal materials have long faced challenges such as adhesion, corrosion, rapid wear, and high noise. Ultra-high molecular weight polyethylene (UHMWPE) sheets, with their superior wear resistance, impact resistance, self-lubricating and non-adhesive properties, are gradually emerging as the standard lining for modern mining equipment, safeguarding the stability and efficiency of the production line.
Silo Blockage Prevention and Arching: Say Goodbye to "Intestinal Obstruction"
Wet materials (ore, wet coal, clay), especially in the conical parts, easily adhere to the silo walls, forming holes and arches, leading to uneven discharge and requiring manual cleaning, which is not only inefficient but also extremely dangerous.
Therefore, laying UHMWPE sheets as linings on the inner walls of silos, especially in the conical and discharge areas, perfectly solves this problem.
In an iron ore concentrate silo in Johannesburg, South Africa, our 20mm thick UHMWPE sheets were fully installed. After the upgrade, adhesion was reduced by 90%, essentially achieving gravity-fed material flow. Our UHMWPE sheets saved the company up to $2 million annually in silo cleaning and capacity loss costs.
Clubbing Wear Resistance and Noise Reduction: Creating a "Silent High-Speed Passage"
Ore, coal, and slag fall at high speed in chutes, causing severe impacts on the bottom impact points. Metal chute liners wear quickly, generate significant noise, and require frequent replacement.
Therefore, we installed UHMWPE sheets as wear-resistant linings on the chute bottom plate, side plates, and material impact surfaces.
We installed linings at the main shaft transfer point of a coal mine in Mexico City, replacing the original 16mm thick wear-resistant steel plates with 30mm thick UHMWPE sheets. After the upgrade, the lining lifespan increased from the usual 6 months to over 5 years. Simultaneously, operating noise decreased from 120 decibels to below 80 decibels, significantly improving the working environment. The overall cost of a single replacement is lower than that of metal steel plates, increasing service life and reducing replacement frequency. Simultaneously, reduced noise levels reduce occupational health management costs.
As a crucial component in silos and chutes, UHMWPE sheets, due to their extended service life, reduce manufacturers' procurement costs, minimize personnel and maintenance costs, and reduce production losses due to downtime caused by maintenance.
UHMWPE sheets are wear-resistant, impact-resistant, self-lubricating, and have zero adhesion, preventing material blockage, minimizing flow resistance, and ensuring safety and environmental friendliness, thereby improving production efficiency.
BEYOND UHMWPE sheets are specifically designed for harsh working environments. We provide not just sheets, but a set of complete, systematic wear-resistant solution.
The extremely high wear resistance and impact resistance of UHMWPE material allow it to easily withstand the impact of sand and gravel. Meanwhile, its corrosion resistance makes it more suitable for various complex mineral compositions, including acidic, alkaline, and saline media. Its low noise and non-toxic, odorless nature make it safer and more environmentally friendly.
Our UHMWPE sheet thicknesses range from 8mm to 260mm, meeting the requirements of customers with varying wear intensities. Our CNC machining centers can provide non-standard custom machining, providing complete lining plates for conical silos and chute elbow lining plates to achieve seamless installation of UHMWPE sheets. We also provide professional securing accessories such as countersunk bolts and ceramic fasteners to ensure a secure installation.

FAQ
Q1: What is the temperature resistance of our UHMWPE sheets? Can they be used for high-temperature materials?
A: The long-term operating temperature of our UHMWPE sheets is -260℃ to +80℃. They can withstand temperatures below 100℃, but we do not recommend prolonged use in environments exceeding 80℃. However, if high-temperature materials are considered, we can modify the sheets to suit the specific working environment and meet customer needs.
Q2: Is installation complicated? Is special equipment required for installation?
A: Installation is very simple and does not require special equipment. First, we process the sheets according to the customer's drawings and then proceed to the construction site. The sheets can be installed using bolts, welding, or bonding. We provide installation instructions, drawings, and professional fasteners. Only cutting and drilling tools are needed on-site.
Q3: What are the advantages of UHMWPE sheets compared to ceramic liners?
A: UHMWPE sheets have the advantage of extremely high impact resistance and ease of processing. While ceramic sheets have high hardness, they are brittle and cannot withstand the impact of large materials. Furthermore, material accumulation is prone to occur at the joints, making cleaning difficult.
Q4: How should I choose the thickness of the UHMWPE sheets?
A: The thickness of the sheets depends on the hardness, shape, flow rate, drop, and equipment dimensions of the material. Generally, 30-70mm thick sheets are used for high-impact chute liners and silo impact areas, while 15-30mm thick sheets can be used for general silo wall panels. Of course, our professional engineers will provide you with more specialized wear-resistant solutions based on your engineering environment.
