Polyurethane Conveyor Belt Cleaner Blades

Primary & Secondary Conveyor Belt Cleaners

TUFFLEX Conveyor Belt Cleaners provide effective carryback control for heavy-duty belt conveyor systems in mining, quarrying, cement, coal handling, aggregate processing and mineral processing plants.

The product range covers Primary Belt Cleaners / Pre-Cleaners, Secondary Belt Cleaners, Tertiary Belt Cleaners, Polyurethane Scraper Blades, Tungsten Carbide Cleaner Blades and V-Plow Belt Cleaners.

Complete systems can be supplied with cleaner blades, mounting shafts, brackets and spring, mechanical, pneumatic or hydraulic tensioning configurations according to the conveyor application.

Multi-Stage Conveyor Belt Cleaning

No single cleaner configuration is ideal for every conveyor.

Material characteristics, moisture, belt speed, pulley diameter and operating environment determine how aggressively the belt must be cleaned.

For heavy mining applications, a combination of primary and secondary cleaners provides an effective approach to carryback control.

Primary Belt Cleaner / Pre-Cleaner

A Primary Belt Cleaner is normally installed around the head pulley, where the belt is supported against the cleaning force.

Its primary purpose is to remove the majority of bulk material immediately after discharge.

Wear-resistant polyurethane is commonly selected for primary cleaner blades because its elasticity allows effective belt contact while providing resistance against abrasion and impact.

Secondary Belt Cleaner

A Secondary Belt Cleaner is positioned after the primary cleaner to remove fine material remaining on the belt.

Secondary systems may use Polyurethane Scraper Blades, Tungsten Carbide Belt Cleaner Blades or composite cleaning elements depending on the material and belt condition.

For highly abrasive ore and fine carryback, carbide cleaning edges provide excellent wear resistance.

Tertiary Belt Cleaner

A tertiary cleaning stage can be installed where a particularly clean return belt is required.

This configuration is suitable for enclosed plants, sensitive transfer points and conveyors where remaining carryback creates significant maintenance problems.

Belt Cleaner Blade Materials

TUFFLEX provides several blade materials for different operating environments.

Polyurethane Cleaner Blades provide abrasion resistance, flexibility and impact absorption for primary and general cleaning.

Tungsten Carbide Scraper Blades provide a hard cleaning edge for secondary cleaning and abrasive applications.

Composite and Special-Purpose Blades can be developed for specific temperature, corrosion and material-handling conditions.

Correct material selection helps balance cleaning performance, belt protection and blade service life.

Cleaner Tensioning Systems

Proper tension maintains blade contact with the conveyor belt as the cleaning edge wears.

Available configurations include:

• Spring Tensioned Belt Cleaners
• Mechanical Tensioners
• Air Tensioning Systems
• Hydraulic Tensioning Systems

The tensioning arrangement is selected according to cleaner size, belt width, installation space and maintenance requirements.

Typical Specifications

Reduce Carryback & Conveyor Maintenance

Uncontrolled carryback can increase housekeeping requirements and allow material to accumulate around conveyor structures.

A properly designed belt cleaning system removes material near the discharge point before it travels along the return belt.

This can help:

• Reduce carryback accumulation
• Keep conveyor structures cleaner
• Reduce material buildup around return idlers
• Reduce manual cleaning requirements
• Improve conveyor operating conditions
• Reduce unnecessary material loss

Applications

TUFFLEX belt cleaners are designed for conveyors operating in iron ore mines, copper mines, gold mines, coal preparation plants, aggregate quarries, cement plants, steel mills, power plants and port bulk handling terminals.

Solutions are available for dry abrasive ore as well as wet, sticky and fine materials.
