Overview
Application & process role
The WLB belt conveyor is the standard transfer equipment used in TONZO sand and aggregate production lines. It connects crushing, screening, washing, recovery and stockpile sections, especially around PSJ roller crushers and SHY washing/dewatering/recovery machines.
Because conveyor performance depends strongly on site layout, belt angle, material condition and transfer distance, model selection should be confirmed together with the complete line flow.
Principle
Operating principle
The motor and reducer drive the head pulley to rotate. Friction between the pulley and rubber belt drives the belt to run continuously. Trough idlers support the loaded upper belt, return idlers support the lower belt, and material is transferred horizontally or at a small inclination to the next equipment section.
Configuration
Series and configuration groups
WLB Standard Belt Conveyor

Selection Note
Model range notes
WLB standard belt conveyor models are listed by belt width. Conveying capacity ranges are common references and should be checked against belt speed, inclination angle, material bulk density and transfer distance.
Display Logic
Website structure
Shown as the standard aggregate belt conveyor page. Conveyor belts, rollers, pulleys, cleaners and brackets are shown as related spare parts rather than separate machine pages.
Advantages
Core advantages
- Strong line compatibility for crushers, screens, SHY washing machines, roller crushers and stockpile transfer.
- Stable conveying with low noise and lower resistance compared with scraping transfer structures.
- Flexible layout for horizontal conveying or small-angle inclined conveying, commonly within 0-20 degrees.
- Modular length design; a single conveyor can be configured up to about 40 m according to site needs.
- Standardized rollers, belts and pulleys make maintenance and replacement easier.
- Waterproof idlers, rubber-lagged pulley and belt cleaner options suit wet washing-line conditions.
Limits
Operating limits
- Large inclination angles require special belt pattern, sidewall structure or another conveying solution.
- Capacity changes with material bulk density, belt speed, belt width, inclination angle and loading condition.
- Wet fine sand can stick to the belt, so cleaner selection and regular maintenance are important.
Maintenance
Daily maintenance points
- Install impact idlers at loading points to reduce stone impact on the belt.
- Use double labyrinth waterproof idlers in washing lines to reduce mud and water entering bearings.
- Install a head cleaner to remove wet fine sand attached to the belt.
- Check belt tension and tracking weekly; adjust tail screw tensioning when needed.
- Add waterproof high-temperature grease to pulley and idler bearings monthly according to site condition.
- Repair or replace torn and peeling belts in time to avoid material leakage and frame wear.
System Flow
How the process works
Raw material bin
Material is fed into the crushing and transfer line.
Jaw crusher
Large material is reduced before downstream transfer.
WLB belt conveyor
Material is transferred to the next crushing or washing equipment.
PSJ double roller crusher
Fine crushing or sand particle-size control is carried out when required.
WLB belt conveyor
Crushed material is transferred to washing and recovery equipment.
SHY washing, dewatering and recovery machine
Sand washing, fine sand recovery and dewatering are completed in one integrated machine.
Finished sand conveyor
Clean finished sand is transferred to the stockpile.
Structure
Main machine units
Frame
Sectional welded C-channel or channel-steel frame with bolted joints for easier transport and installation. Anti-corrosion painting or rust-resistant coating can be used for washing-line sites.
Conveyor belt
Rubber patterned belt or polyester canvas belt for aggregate lines. Common belt widths include 600, 800, 1000 and 1200 mm; wet washing lines can use wear-resistant and tear-resistant belts.
Idler sets
Upper trough idlers carry material and reduce spillage. Return idlers support the lower belt. Impact idlers are used at loading points and training idlers can be added for long conveyors.
Pulleys
Head drive pulley and tail bend pulley with bearing housings. Rubber lagging can improve traction for wet sand, and waterproof grease is used for washing environments.
Tension device
Tail screw tensioning adjusts belt tightness to reduce slipping, sagging and unstable running.
Drive assembly
Motor plus hard-tooth reducer is the standard drive option. Motorized pulley configuration can be considered where space is limited.
Auxiliary parts
Cleaner, skirt board, bracket, hopper, cover and guard are matched according to transfer point and site layout.
Model / Size Data
WLB standard conveyor references
Tables show common size ranges. Final configuration is checked by material hardness, mud and moisture, capacity, product size, upstream / downstream equipment and site layout.
The following ranges are common references for aggregate and sand lines. Actual conveying capacity depends on belt speed, inclination angle, material bulk density, loading condition and site layout.
| Model | Belt width | Common belt speed | Capacity reference | Matched equipment |
| WLB600 |
600 mm | 1.2-1.6 m/s | 40-100 t/h | SHY1230 small washing machine; small roller crusher |
| WLB800 |
800 mm | 1.3-1.8 m/s | 100-260 t/h | SHY1530; small and medium crushing sets |
| WLB1000 |
1000 mm | 1.4-2.0 m/s | 200-480 t/h | SHY1840 standard three-in-one machine; medium roller crusher |
| WLB1200 |
1200 mm | 1.5-2.0 m/s | 350-750 t/h | SHY2040 large washing machine; high-capacity crushing line |

Material
Material check
Material size, moisture, bulk density, transfer length, installation angle and connected equipment should be confirmed before conveyor selection. Wet sand and washing-line sites need stronger waterproof and anti-wear parts.
