Conveyor pully

ZOOMRY Conveyor Pulleys are essential components for belt conveyor systems, providing driving force, directional changes, and proper belt tension. Our comprehensive range includes drive pulleys (head pulleys), bend pulleys, tail pulleys, take-up pulleys, and snub pulleys — all engineered for reliable operation in mining, quarrying, cement, and bulk material handling applications. Manufactured with high-quality 16Mn steel shells and 45#/40Cr/42CrMo shafts, each pulley undergoes CNC four-roll rounding, ultrasonic flaw detection, and tempering stress relief — ensuring ovality below 1.5mm and a service life exceeding 50,000 hours.

ZOOMRY conveyor pulleys are core components of belt conveyor systems, serving critical functions including driving, redirecting, and tensioning the Conveyor Belt. Our comprehensive pulley range covers every position in the conveyor circuit — from high-torque drive pulleys at the head end to precision-engineered snub pulleys for wrap angle optimization. Each pulley is manufactured under ISO 9001 quality control with finite element stress analysis to ensure optimal structural integrity under heavy loads and harsh conditions.

What Types of Conveyor Pulleys Does ZOOMRY Offer?

Drive Pulley (Head Pulley) – transmits torque from the drive motor to the conveyor belt, providing the driving force for material transport. Available with rubber or ceramic lagging for enhanced traction.
Tail Pulley / Bend Pulley – redirects the conveyor belt at the loading end or changes belt direction at system bends. Provides tension to maintain stable belt tracking.
Take-up Pulley – maintains proper belt tension to prevent slippage and ensure stable operation. Gravity-weighted designs automatically compensate for belt stretch and thermal expansion.
Snub Pulley – increases the belt wrap angle around the drive pulley for improved traction, reducing belt pulling force and optimizing system cost.
Motorized Pulley – a compact, self-contained drive unit integrating motor, reducer, and bearings inside the pulley shell for space-constrained conveyor layouts.
Lagged Pulley – features ceramic, diamond-grooved rubber, or plain rubber lagging to increase friction and extend pulley service life in abrasive environments.
Quarry Duty Pulley – rugged design for the toughest applications where downtime must be minimized, built to withstand abrasive materials and continuous 24/7 operation.

Why Does Pulley Quality Matter for Conveyor Reliability?

The conveyor pulley is the power transmission heart of any belt conveyor system. A poorly manufactured pulley leads to premature bearing failure, shell deformation, belt slippage, and unplanned downtime that can halt entire production lines. ZOOMRY pulleys are engineered to eliminate these risks: CNC four-roll rounding ensures shell ovality below 1.5mm for smooth belt tracking; ultrasonic flaw detection after welding eliminates internal crack risks; and tempering stress relief removes residual stresses that cause long-term deformation under heavy cyclic loads.

For operations in mining, cement, and quarry environments, our pulleys are available in belt widths from 400mm to 2,400mm with custom lagging and hub configurations to match any drive requirement.

Materials

According to different environments and stress conditions, ZOOMRY selects appropriate materials for each pulley component:

Shaft Materials: 45# steel, 40Cr, 42CrMo – chosen for their strength, toughness, and wear resistance under varying load conditions.
Shell (Drum Skin) Material: 16Mn steel plate – provides excellent weldability, strength, and impact resistance for heavy-duty applications.
Lagging Options: Rubber lagging (plain or diamond pattern) for standard applications; ceramic lagging for abrasive environments; replaceable lagging for cost-effective maintenance.
