Belt Cleaners

What it is

Belt cleaners remove carryback — material that sticks to the belt past the discharge pulley and drops along the return run. Primary cleaners usually sit against the drive pulley; secondary cleaners work on the flat belt after the pulley; tertiary or plough devices address stubborn fines or protect tail pulleys. Blades may be polyurethane, carbide or other wear materials depending on abrasion and belt cover type.

Effective cleaning needs correct tip pressure, blade angle, mounting rigidity and a maintenance habit for tensioning and tip replacement. Cleaners are not a substitute for good chute sealing and skirt systems, but they are essential on wet coal, clayey ores and sticky concentrates common on South African plants. Stainless or coated hardware lasts longer in corrosive wash-down areas.

Note belt width, belt speed, material type, pulley diameter and whether the belt has mechanical fasteners when you request cleaner quotes. Fasteners can limit which blade systems are safe to use.

Use cases

Cleaners are fitted on new conveyors as standard practice, retrofitted where spillage under the return belt has become a housekeeping and safety problem, and upgraded when blade life is too short for the duty. Plants with long galleries gain the most: less shovelling, fewer idler seizures from fines build-up, and cleaner walkways for inspections.

• Primary scraper at head pulley — first cut of coarse carryback
• Secondary cleaner — fines removal for sticky products
• V-ploughs ahead of tail pulleys — protect against material trapped on the return belt
• Reversible belt systems — dual cleaner arrangements and careful geometry

Share photos of the current mounting space and any chute work that restricts access. Some head chutes leave little room for a robust primary cleaner — suppliers need that constraint early. If wash-down or chemical sprays are used near the head, mention that as well so hardware and springs are specified for corrosion rather than painted mild steel that seizes after a few months.

Industries

Coal handling, platinum and chrome processing, iron ore, aggregate washing plants and cement raw mills are heavy cleaner users because product sticks or abrades. Sugar, grain and fertiliser plants care about cleanliness and dust. Ports need cleaners that cope with wet bulk cargoes and limited maintenance windows between vessels.

Underground conveyors need compact, serviceable designs that crews can tension safely. Surface overland belts prioritise blade life and remote inspection. Matching supplier experience to sticky versus abrasive duty avoids fitting a soft blade where carbide is justified, or the reverse. Plants that already standardise on a cleaner brand should say so — tip compatibility often matters more than swapping the entire mainframe during a short shutdown.

Why it matters

Carryback creates spillage that buries return idlers, damages belt edges and creates slip and fall hazards in galleries. It also wastes product and increases cleanup labour — a quiet but large operating cost on many South African mines and plants. Good cleaning protects the belt investment and keeps structure visible for inspection. When cleaners are neglected, the plant pays repeatedly through idler consumption and belt edge repairs that look unrelated at first glance.

Compare quotes on blade material, tensioning method, spare tip availability and service support — not only the frame price. Conveyor Quotes connects you with cleaner specialists; you can also select related categories such as skirt rubber and scrapers in the same request when the spillage problem is wider than blades alone. A single coordinated brief usually produces more useful site visits than three separate emails with incomplete context.
