Overview
Application & process role
The XSJ chain bucket elevator is an inclined wet-material lifting unit for sand washing lines. It is especially suitable after WLGSX trommel screening and before SHY washing, dewatering and fine sand recovery equipment.
For dry material transfer, XSJ can be used for coarse bulk material, but enclosed vertical bucket elevators are more suitable where dust control and fine dry powder lifting are the priority.
Principle
Operating principle
The drive sprocket pulls the double chain and buckets along the inclined frame. Wet sand or washed aggregate enters the lower trough, is lifted by perforated buckets, drains water during lifting and discharges at the upper chute. Overflow water returns through the trough or return channel according to site layout.

Selection Note
Model range notes
XSJ model numbers represent the effective bucket width in millimeters.
Display Logic
Website structure
Shown as a washing-line inclined chain bucket elevator. It should be separated from NE / TH vertical bucket elevators because XSJ is open, inclined and designed for wet sand drainage, while NE / TH elevators are enclosed dry-material lifting machines.

How buyers should choose this equipment type
Wet sand lifting
Recommended for wet sand, slurry-like sand, muddy aggregate, washed sand and tailings sand. Perforated buckets and overflow return structure help drain water and reduce fine-sand loss.
Dry bulk transfer
Can convey dry river sand, crushed stone, stone powder, tailings and limestone for coarse transfer, but it is not the first choice for enclosed fine powder conveying.
XSJ vs NE / TH bucket elevator
XSJ is inclined and open with drainage structure for washing lines. NE / TH elevators are vertical and enclosed for dry material, without drainage and not suitable for long-term mud slurry operation.
Advantages
Core advantages
- Designed for washing-line wet sand lifting, draining water while lifting material.
- Perforated buckets reduce water carryover and help connect WLGSX trommel screen with SHY washing equipment.
- Thickened chain and buckets can be matched for muddy, abrasive and wet aggregate conditions.
- Waterproof labyrinth sealing helps protect bearings in mud and water environments.
- Compatible with dry coarse bulk materials when dust control is not the key requirement.
- Open inclined layout is easier to inspect and maintain in sand washing yards.
Limits
Operating limits
- Open structure creates more dust when conveying dry powder, so enclosed NE / TH bucket elevators are better for fine dry powder.
- Not a precision screening or washing machine by itself; it is a lifting and transfer unit in the washing line.
- Final lifting angle, height and foundation layout must be confirmed with the complete line arrangement.
Maintenance
Daily maintenance points
- Check chain tension, bucket bolts and chain joint wear regularly.
- Inspect sprocket teeth, pins and sleeves; replace worn transmission parts in time.
- Keep waterproof bearing seals and grease points in good condition for mud-water operation.
- Check bottom trough liners and bucket liners for wear from wet sand and stone.
- Clean accumulated mud in the feed trough and overflow return area when needed.
System Flow
How the process works
PSJ double roller crusher
Material is finely crushed or particle size is adjusted before washing-line pretreatment.
WLGSX trommel screen
Wet material is pre-screened and muddy lumps or large stones are separated.
XSJ chain bucket elevator
Wet sand is lifted while water drains through bucket holes and returns through the trough.
SHY washing, dewatering and recovery machine
Sand washing, fine sand recovery and dewatering are completed.
WLB belt conveyor
Finished material is transferred to the stockpile.
Structure
Main machine units
Drive assembly
Motor, hard-tooth reducer, drive base and backstop to prevent reverse material flow.
Head assembly
Drive sprocket, head shaft, waterproof bearing housing and discharge chute.
Tail tension assembly
Tail sprocket, tail shaft, screw-spring tensioning mechanism and lower feed trough.
Traction and carrying parts
Double chain, bucket, bucket connection bolts and pins. Chain and buckets can be thickened for wet abrasive sand.
Frame and trough
Sectional channel-steel frame, side guards, bottom wear liner and overflow water return channel.
Support and service parts
Support rollers, wear-resistant rail strips, inspection platform and guardrail according to site layout.
Model / Size Data
XSJ standard model 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 public ranges are common references for wet sand lifting. Actual capacity depends on moisture, material grading, lifting height, bucket speed and site layout.
| Model | Bucket width | Wet sand capacity reference | Matched equipment |
| XSJ600 |
600 mm | 30-60 t/h | SHY1230 small washing line |
| XSJ800 |
800 mm | 60-110 t/h | SHY1530 small and medium washing line |
| XSJ1000 |
1000 mm | 110-180 t/h | SHY1840 standard three-in-one machine |
| XSJ1200 |
1200 mm | 180-280 t/h | SHY2040 large high-capacity sand washing plant |

Used for wet sand lifting, drainage during lifting and process transfer between WLGSX trommel screen, SHY washing/dewatering/recovery machine and stockpile conveying sections.
Material
Material check
XSJ is mainly positioned for wet sand and washing-line material with about 10%-28% moisture. It can also handle dry sand, crushed stone, stone powder, tailings and limestone, but open dry operation creates more dust than enclosed vertical bucket elevators.
