Wear Protection Coatings for Screening Machines | Vibrating Screens & Screening Equipment | MetaLine

Classification of bulk materials is synonymous with wear, wear and even more wear. Vibrating screens, screening machines and screening equipment used in mining and quarrying operations are exposed to continuous vibration, abrasive material flow and constant mechanical loading in both wet and dry processing environments.

Under these conditions, screen supports, discharge zones, housings and other structural components are subject to severe abrasion, impact damage and progressive corrosion. Maintenance and repair often have to be carried out quickly on site in order to minimize costly downtime.

MetaLine elastomeric coating systems provide seamless, impact-absorbing surface protection that significantly extends the service life of screening machinery. The highly elastic protective lining resists abrasion, absorbs vibration and protects steel components against progressive wear.

Unlike conventional rubber linings with joints, seams and edge transitions, the MetaLine synthetic spray elastomer creates a completely seamless protective layer. This improves durability, simplifies repair work and helps maintain the structural integrity of heavily loaded machine components.

Typical failure mechanisms in screening machines

Abrasion caused by highly abrasive bulk materials
Impact wear from coarse particles and changing material flow
Corrosion caused by moisture, slurry and aggressive process media
Material fatigue due to permanent vibration and oscillation
Localized wear at support zones, discharge areas and transitions

These combined loads continuously attack the machine structure and can quickly lead to material loss, structural weakening and unplanned shutdowns if surfaces are left unprotected.

Why elastomeric coatings work

MetaLine Series 700 elastomeric coatings are specifically designed for extreme wear conditions in vibrating process equipment. Their elasticity allows them to absorb impact energy and compensate for dynamic movement without becoming brittle or detached.

Unlike rigid coatings or segmented lining systems, elastomeric spray coatings form a seamless protective membrane with strong adhesion to the substrate. This reduces weak points and provides long-term resistance to abrasion, vibration and wet service conditions.

Typical advantages include:

Seamless protective lining without joints or gaps
Excellent resistance to abrasion and sliding wear
High elasticity under permanent system vibration
Strong adhesion to steel substrates
Fast and practical on-site repair capability

MetaLine Series 700 is an internationally proven OEM protection solution for wet and dry screening machines of all sizes. Exposure to saltwater or demineralized water is also permitted.

Typical components and applications

MetaLine coatings are used on a wide range of vibrating screens, screening machines and classification equipment, including:

Multi-deck screening machines
Vibratory sizers
Rotary screening machines
Wet screening machines
Banana screening frames
Tumbler screening machines
Drum screening machines
Log washers
Bar sizers

These systems are commonly used in mining, quarrying and bulk material processing applications where reliable continuous operation and long wear life are essential.

Application limits

MetaLine elastomeric coatings provide excellent protection against abrasion, vibration and wet service exposure, 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 oil, dust or residues without proper preparation
Structural defects or unstable substrates that prevent durable adhesion

The correct coating system and layer thickness should always be selected according to the specific wear load, material throughput, vibration profile and chemical exposure of the application.
