Product Overview

ZOOMRY V-return Belt Cleaner is a third-stage cleaning device mounted on the non-working (inside) surface of the return belt — after the primary and secondary scrapers have cleaned the carrying side. Its V-shaped polyurethane blade splits accumulated material to both sides of the conveyor, preventing buildup on return rollers that causes belt mistracking and premature roller failure. In high-dust environments like cement plants and coal handling, a V-return cleaner typically extends return roller service life by 30–50%.

When Do You Need a V-Return Cleaner in Your Conveyor System?

Not every conveyor requires a V-return cleaner. It becomes essential when:

• Material reaches the return side — sticky materials like clay, wet coal fines, or gypsum bypass primary and secondary scrapers and adhere to the belt's inside surface.
• Return rollers show uneven wear — material buildup on rollers creates diameter variations that pull the belt off-track.
• Cleanup labor costs are rising — manual shoveling of spillage under the return run adds recurring operating expense.
• Belt splice damage is frequent — hardened material lumps on the inside belt surface can crack mechanical splices as they pass over pulleys.

In fertilizer and chemical plants, V-return cleaners are particularly valuable — hygroscopic materials like urea and potash absorb atmospheric moisture and form a corrosive paste on the belt's inside surface.

Advantages

• V-shaped self-aligning blade — automatically centers material flow to both discharge sides, preventing one-sided buildup.
• Dual-side material discharge — splits debris evenly to both sides of the conveyor, eliminating uneven roller loading.
• Polyurethane blade with high wear resistance — smooth, bubble-free PU surface extends blade service life in abrasive environments.
• Adjustable mounting frame — fits belt widths from 600 to 2,000 mm with simple bolt-on installation to the conveyor stringer.
• Corrosion-resistant construction — 35# carbon steel frame with optional hot-dip galvanizing for chemical and marine environments.
• Low maintenance design — spring-tensioned blade maintains consistent contact without daily adjustment.

How a V-Return Cleaner Completes the Three-Stage Cleaning System

A complete Conveyor Belt cleaning strategy uses three stages working in sequence: the primary cleaner removes 70–80% of carryback at the head pulley, the secondary cleaner captures fine residual material, and the V-return cleaner handles the inside belt surface — the only component addressing the non-working side. Skipping the V-return stage means inside-surface buildup continues unchecked, eventually causing return rollers to seize or belt tracking to drift beyond correctable limits.

Common Applications

• Coal handling and power plants — wet coal fines and fly ash that bypass primary scrapers and cake onto the return belt surface.
• Cement and clinker production — raw meal and clinker dust that hardens on return rollers, causing premature bearing failure.
• Fertilizer and chemical processing — hygroscopic materials like urea and ammonium phosphate that form corrosive paste layers.
• Mining and mineral processing — sticky clay, bauxite, and laterite ores that adhere aggressively to belt surfaces in wet conditions.
• Aggregate and quarry operations — limestone and sand dust accumulation that increases return roller diameter and triggers belt wander.
