Primary Belt Cleaners
Martin® Engineering primary belt cleaners and belt scrapers for removing bulk carryback at the head pulley, supplied and supported by Oreflow across Australia.
HEAD PULLEY CLEANING
Mounted at the discharge point while the belt remains supported by the head pulley.
BULK CARRYBACK REMOVAL
Removes the main layer of material before it travels along the return side.
FIRST-STAGE PERFORMANCE
Works with secondary cleaners to achieve a cleaner, more consistent return belt.
Primary Belt Cleaners for Mining and Bulk Handling
Oreflow is an authorised Australian distributor of Martin® Engineering belt cleaning equipment.
A primary belt cleaner, also commonly called a primary belt scraper, is installed against the head pulley near the conveyor discharge point. It removes the bulk layer of carryback while the belt remains supported by the pulley, forming the first stage of the belt cleaning system.

Martin Engineering Primary Belt Cleaner Range
Martin® Engineering offers primary cleaners for different belt widths, speeds, pulley diameters, operating duties and installation requirements.
Use the product comparison as an initial guide. Final selection should be confirmed against the conveyor dimensions, material characteristics and current Martin technical data.

How Primary Belt Cleaners Work in a Staged System
A primary cleaner is generally mounted against the head pulley below the material discharge trajectory. Its blade is held in controlled contact with the belt, removing the bulk layer of carryback while the belt is supported by the pulley.
The removed material is directed into the discharge area rather than continuing along the return side of the conveyor.
A primary cleaner is not normally expected to produce a completely clean return belt on its own. In demanding mining and bulk materials handling applications, it is commonly followed by a secondary cleaner, which removes finer residual material after the belt leaves the head pulley.
Wet, sticky, fine or difficult materials may require additional or application-specific cleaning stages. Where a standard primary and secondary arrangement is unsuitable, Oreflow can also assess options from the specialty belt cleaner range.
Selecting the Right Primary Belt Cleaner
The correct primary cleaner depends on the conveyor duty, head pulley arrangement and material being handled. Key selection factors include:
- Belt width, speed and direction of travel
- Head pulley diameter and available mounting position
- Material type, moisture, abrasiveness and carryback
- Belt condition and mechanical splice type
- Discharge-chute layout and maintenance access
- Blade configuration and tensioning requirements
Oreflow can assess these details to identify a suitable Martin Engineering cleaner and blade arrangement. High-speed or heavy-duty conveyors, large pulley diameters and restricted discharge areas may require a specialised configuration.
Replacement Blades and Product Support
Blade wear, contact, tension and cleaner alignment should be checked during planned conveyor inspections. Adjustment and replacement requirements vary between cleaner models and should follow the relevant Martin technical documentation.
Oreflow can supply compatible Martin replacement blades and assist with product information for the selected cleaner.
Frequently Asked Questions
What is a primary belt cleaner?
A primary belt cleaner is the first cleaning stage on a conveyor. It removes the bulk layer of material remaining on the belt at the head pulley after discharge.
Is a primary belt cleaner the same as a primary belt scraper?
Yes. Primary belt cleaner and primary belt scraper are commonly used to describe the same type of equipment. Martin generally uses the term belt cleaner in its product names.
Where is a primary cleaner installed?
It is generally mounted against the head pulley near the discharge point, below the material trajectory. The exact position depends on the selected model and conveyor geometry.
Is a primary cleaner enough on its own?
It depends on the material and required cleaning standard. In demanding applications, a primary cleaner is commonly followed by a secondary cleaner to remove the finer material left on the belt.
How is a primary belt cleaner selected?
Selection should consider belt width, belt speed, head pulley diameter, material characteristics, temperature, belt and splice condition, operating environment and available installation space.
Can Oreflow supply Martin primary belt cleaners in Australia?
Yes. Oreflow is an authorised Australian distributor of Martin® Engineering belt cleaners and can assist with model selection, supply, technical information and replacement blades.
