Nylon central cylinder for flotation machines used in mining machinery.

1. Excellent Wear and Corrosion Resistance
Abrasion Resistance: Nylon material has excellent wear resistance, resisting continuous erosion from solid particles in mineral slurries. Its wear life is 3-5 times that of ordinary carbon steel, especially advantageous when processing highly abrasive minerals.
Chemical Corrosion Resistance: It has good resistance to water, weak acids, weak bases, and most flotation reagents (such as xanthates, dithiophosphates, and frothing agents) in flotation slurries. It never rusts, avoiding leakage problems caused by corrosion and perforation of metal cylinders.
Smooth Surface: The nylon surface is smooth after molding, making it less prone to scaling or mineral adhesion, which helps maintain a stable slurry flow cross-section.
2. Excellent Mechanical Properties and Stability
High Strength and Rigidity: Especially glass fiber reinforced nylon (PA66+GF), which has very high mechanical strength and rigidity, able to withstand the static pressure, dynamic pressure, and installation stress of the mineral slurry, and is not easily deformed during long-term use.
Impact Resistance and Shock Absorption: Nylon has good toughness, effectively cushioning impacts from slurry fluctuations or accidental operations, and absorbing some vibrations, contributing to smoother equipment operation.
Good Dimensional Stability: Nylon parts that have undergone appropriate heat treatment and post-treatment have controlled moisture absorption, maintaining stable geometric dimensions and installation accuracy under working conditions.
3. Lightweight and Convenient Installation and Maintenance
Extremely Lightweight: The density is approximately 1.15-1.16 g/cm³, and the weight is only 1/7 of a steel center cylinder of the same specification. This makes handling, installation, and disassembly exceptionally easy, greatly reducing labor intensity and safety risks.
Insulation and Safety: Nylon is an excellent electrical insulating material, improving the electrical safety of the equipment. There is no risk of sparks during operation, making it safer.
The nylon center cylinder for flotation machines is a typical successful application of "replacing steel with plastic." Through material innovation, it effectively solves the shortcomings of short lifespan and maintenance difficulties of traditional metal parts in corrosive and abrasive environments. Its core value lies in providing users with a reliable solution that offers longer service life, lower maintenance costs, higher safety, and better overall economic benefits. For modern mineral processing plants striving to reduce operating costs, improve equipment reliability, and achieve safe and efficient production, adopting high-performance nylon center cylinders is a wise and highly rewarding technological upgrade.
