Cyclones, separators and sifters operate under extremely abrasive conditions. High-velocity particle streams continuously impact internal surfaces, especially in inlet zones, cylindrical bodies and separation cones.
Over time this constant particle impact leads to severe erosion, wall thinning and reduced separation efficiency. Abrasive dust, sand, minerals and process solids can rapidly destroy unprotected steel components.
MetaLine elastomeric coating systems provide impact-absorbing surface protection that significantly extends the service life of cyclone and separation equipment while maintaining the original geometry of the component.
The seamless elastomer lining absorbs particle impact energy and helps prevent progressive erosion of the steel structure.
Typical failure mechanisms in cyclones and separators
• Abrasion caused by high-velocity dust and solid particles
• Erosion in cyclone inlet zones
• Sliding wear in separation cones and discharge sections
• Corrosion in chemically aggressive environments
• Localized wear leading to reduced separation efficiency
High-velocity particle streams repeatedly strike internal walls, particularly near the inlet and high-turbulence areas, causing progressive material loss and frequent maintenance requirements.
Why elastomeric coatings work
MetaLine Series 700 elastomeric coatings are specifically designed to absorb mechanical impact energy while maintaining strong adhesion to the substrate.
Unlike rigid ceramic or metallic liners, elastomeric coatings deform elastically under particle impact and help prevent brittle fracture or liner detachment.
Typical advantages include:
• Seamless and stress-free protective lining
• Excellent resistance to abrasion and particle impact
• Strong adhesion to steel substrates
• Noise and vibration reduction
• Long service life in abrasive environments
Typical coating thickness for cyclone and separator protection ranges between approximately 2 mm and 10 mm (80–400 mils), depending on the severity of the operating conditions.
Typical components and applications
MetaLine coatings are widely used in industrial particle separation equipment such as:
• Dust collection cyclones
• Hydrocyclones
• Centrifugal separators
• Decanter hoods
• Turbo separators
• Vibratory sifters and screening systems
• Powder and bulk material separation systems
These systems are commonly used in industries such as mining, cement production, power generation, recycling and bulk material processing where abrasive particles must be separated from process streams.
Application limits
MetaLine elastomeric coatings provide excellent protection against abrasion and particle impact, but application limits must always be considered.
Typical limits include:
• Continuous operating temperatures above approximately 80 °C (175 °F)
• Strong oxidizing chemical environments
• Surfaces contaminated with oils or process residues without proper preparation
• Equipment exposed to excessive structural deformation or thermal cycling
Proper coating system selection and thickness should always be evaluated according to the mechanical, thermal and chemical loads of the specific application.
