Abrasion&impact Resistant Magnetic Wear Liner
Structure: Permanent magnet (strong magnetic)+wear-resistant layer (rubber/polyurethane/alumina ceramic/alloy steel), vulcanized or embedded as a whole.
Working principle: Absorb steel ball fragments and magnetic mineral powder to form a dynamic self regenerating protective layer; Wear only occurs in the material layer, and the lining plate body hardly wears, commonly known as "never wearing lining plate".
Installation: No welding, no bolts, no glue, directly attached to the surface of the steel plate, easy to disassemble and assemble.

Key Features and Advantages |
|
Metal Magnetic Liner (MML) |
Secondary ball mill for mining, regrinding ball mill |
The steel shell encases the magnet, providing high strength; a protective layer is formed by adsorbing iron particles; with its thin profile, it increases the effective volume of the mill and enhances grinding efficiency. |
|
Magnetic rubber/ceramic lining plate |
Conveying equipment such as chutes, hoppers, transfer points, and vibrating screens |
The matrix is made of polyurethane or rubber, with embedded magnets or ceramic sheets [6]; it is impact-resistant and corrosion-resistant, requiring no thermal permits for installation; it can be custom-cut on-site, and ceramic sheets are also used to enhance wear resistance. |
|
Removable modular liner |
Chutes and containers in mining and chemical industries that require maintenance |
The wear-resistant ceramic blocks are mounted on a rigid plastic base and combined with a detachable magnetic assembly; the magnetic force is adjustable (single-point suction force: 20–200 kg). For maintenance, a crowbar or lifting ring can be used. |
Key advantage of Magnetic Wear Liner
Maintenance free and long-lasting: The unique self protective layer makes it almost wear-resistant, requiring no maintenance in many applications, far exceeding ordinary lining plates.
Safe and fast installation: No need for hot work (no welding), no need for drilling, single person manual operation. For example, a lining plate weighing about 17 kilograms can be easily transported, reducing downtime from days to hours and significantly improving equipment efficiency.
Improving equipment performance: As there is no need to install bolts, the phenomenon of "powder leakage" is completely eliminated. At the same time, the lining plate is thinner, which increases the working diameter inside the mill and can directly increase the processing capacity.
Improving the working environment: The magnetic fixation structure is tighter, effectively reducing the noise and vibration during equipment operation
Limitation
Only applicable to ferromagnetic substrates: The equipment casing must be made of ferromagnetic steel (ordinary carbon steel), and stainless steel or aluminum equipment cannot be used.
Not suitable for strong non-magnetic materials: If the processed material and grinding medium are completely free of iron and cannot form a protective layer, the lining plate will wear out directly, greatly reducing its lifespan.
Not resistant to ultra-high temperatures: Permanent magnets will demagnetize at high temperatures (usually exceeding 80-100 ° C), so they are not suitable for high-temperature material conveying lines.
Typical Applications
Hydrocyclone: lined with wear-resistant material, replacing rubber/ceramic, bolt free, long service life.
Ball mill/semi autogenous mill: coal grinding for mining, building materials, and electric power.
Chute, silo, pipeline: transporting ore, sand and gravel, coal powder.
Vibration screen and feeder: do not detach in strong earthquake environments.
FAQ
Q: What is the minimum order quantity?
A: Standard-sized products require a minimum order of 100 pieces; custom orders have flexible minimum quantities. Volume purchases (≥500 pieces) qualify for preferential pricing.
Q: What is the service life in mining applications?
A: 3-5 years in coal handling applications; 1-2 years in gold/iron ore (high quartz content) applications – 6-10 times longer than manganese steel liners.
Q: Are installation accessories provided?
A: We supply matching adhesives, bolts, and welding rods, accompanied by installation manuals and video tutorials; on-site technical support is available for large-scale projects.
Q: Does the product comply with international standards?
A: Complies with ASTM, DIN, and ISO standards. Material and performance certified by SGS. Customisable to regional requirements.
Q: How are liner replacements or damage handled?
A: Manufacturing defects covered within the warranty period. We offer wear-and-tear replacements at preferential pricing with expedited delivery to minimise downtime.
