Belt Cleaners · Secondary · Zone 03
Secondary scrapers install just past the head pulley on the return path, cleaning the thin, sticky and moist residue a primary scraper can't. Tungsten-carbide blades and self-tensioning cushions hold cleaning pressure across the belt.
Titan Secondary Scraper
01 / Scraper architecture
The architecture, up close.
A secondary scraper works the fine residue on the return path, where cleaning pressure has to stay constant across the full belt width. Tru-Trac builds that from tungsten-carbide tips, individually flexing cushions and a serviceable cartridge.
- 01
Tungsten-carbide blade tips
Proprietary carbide grades in an overlapping arrangement for streak-free cleaning; tip profile matched to the belt (V-Tips for vulcanised belts, C-Tips or U-Tips for mechanical fasteners).
- 02
Self-tensioning cushions
Impact-absorbing rubber cushions let each blade flex individually and hold a constant effective force against the belt; two-way cushions are available for reversing conveyors.
- 03
Slide-out service cartridge
Blades swap out and inspect without dismantling the mount, cutting downtime.
- 04
Bolt-up tensioner
Simple push-up / pull-up adjustment with a visual tension check; HD versions carry the load in high-speed, high-tonnage duty.
- 05
Optional water spray
Softens sticky or moist carryback where dry cleaning alone can't hold performance.
02 / The range
The secondary range, by duty.
