Vertical Mill Magnetic Liner
We specialize in the R&D, production and sales of wear-resistant parts for mining grinding equipment.In view of the operating characteristics of vertical mills – high rotating speed, uniform force distribution, and frequent loosening of conventional liner bolts – we have professionally developed and produced special magnetic liners for vertical mills.
Featuring a composite structure of high-strength magnetic alloy substrate and wear-resistant alloy surface layer, these liners are directly adsorbed onto the grinding table, roller and inner shell of vertical mills via high-performance permanent magnetic force, with no bolt fastening required.This completely eliminates problems such as loosening, falling off and powder leakage of traditional liners.Our magnetic liners are widely used in various vertical mills for cement, slag, limestone, metallurgical auxiliary materials and other materials, with advantages including long wear life, fast installation, stable operation, light weight and energy saving, effectively reducing vertical mill maintenance costs and downtime.
I. Product Structure and Types of Magnetic Liners for Vertical Mills
Magnetic liners for vertical mills are based on permanent magnets for adsorption, with a composite wear-resistant protective layer on the outside.They are lightweight and feature high fitting accuracy. According to vertical mill structure, they are divided into the following types:
Magnetic Roller Liners
Suitable for the outer curved surface of grinding rollers of various vertical mill specifications.The curved profile closely matches the roller contour with firm magnetic adsorption, protecting the roller base and improving grinding efficiency.
Magnetic Table Liners
Flat-mounted on the working surface of the vertical mill grinding table.The flat structure ensures even stress distribution and excellent resistance to abrasion and scouring.As an alternative to traditional cast steel liners, they are lighter and deliver more stable operation.
Magnetic Shell / Air Duct Liners
Used in vertical mill air inlets, guide air ducts and inner cylinder walls.Resistant to dust scouring, wear and air leakage.Installation requires no drilling and causes no damage to the equipment body.
II. Core Product Performance Features
Magnetic Adsorption Fixation, Bolt-Free & Anti-Loosening
Directly adsorbed onto metal surfaces via high-strength permanent magnets, eliminating bolts, pressure bars and other fasteners.This completely prevents liner loosening, falling off and powder leakage caused by vibration, greatly improving operational safety.
Excellent Wear Resistance & Long Service Life
The surface layer adopts special wear-resistant alloy material, resistant to dust scouring and particle grinding.Service life exceeds that of ordinary high manganese steel liners, greatly extending replacement intervals.
Lightweight Design Reduces Equipment Load
Compared with traditional cast steel liners, magnetic liners have lower self-weight, reducing load on the main shaft and motor, cutting energy consumption and extending the service life of the transmission system.
Easy Installation & Dismantling, High Maintenance Efficiency
No drilling or welding on equipment.Can be handled and installed by a single person, significantly shortening mill maintenance and replacement time and reducing production losses at mines and grinding stations.
High Tightness, Anti-Leakage & Dust Reduction
High fitting accuracy and small splicing gaps effectively prevent internal powder leakage, improving the on-site working environment and reducing environmental protection pressure.
Strong Adaptability & No Damage to Equipment Base
No damage to roller and table surfaces.Can directly replace original liners and fit various domestic and imported vertical mills.
