MS400 × 29.2 m En Masse Scraper Conveyor with 45° Inclined Lifting, Fully Enclosed Trough, and Wear-Resistant Bottom Plate

Product Overview

The MS400 × 29.2 m en masse scraper conveyor is a fully enclosed scraper-type conveyor arranged at a 45° incline, with an overall length of 29.2 meters. It continuously lifts and transfers dewatered sludge and slurry-type bulk materials from a lower elevation to an upper hopper or downstream processing equipment. The fully enclosed trough keeps material contained throughout the conveying path — minimal dust, no odor release — making it suitable for installation in sludge dewatering buildings or mezzanine spaces.

This model is designed for applications requiring elevation change: it receives filter cake from belt or plate-and-frame filter presses upstream and feeds sludge hoppers, dryers, or incineration units downstream.

Construction Features

45° Inclined Lifting Design

The unit is arranged at a 45° angle over a 29.2 m overall length, providing a substantial horizontal projection with corresponding lift height — matching the elevation difference between two floors in a wastewater treatment plant. The incline section relies on internal material friction and scraper thrust to move the bed upward without intermediate transfer points.

Fully Enclosed Trough

Rectangular enclosed housing, built in bolted flange sections and fabricated in segments for field assembly over the 29.2 m length. Material travels in an en masse (buried) state with good sealing, reducing workshop dust and odor.

Drop-Forged Chain Drive

Drop-forged chain at 200 mm pitch offers high fatigue strength for heavy traction under 45° inclined duty. A tail screw tensioner compensates for chain elongation.

Wear-Resistant Bottom Plate

The trough bottom is fully 8 mm wear-resistant plate with 6 mm side plates. Abrasive wear concentrates on the bottom during inclined conveying; the thicker bottom extends the major-overhaul interval, while side plates provide structural strength.

Standardized Drive Components

Tongli gearbox, Wannan motor, and SKF bearings — all mature standard brands with good parts availability; for export projects, SKF's global network supports fast bearing replacement and reduced downtime.

Applications

Elevation Lifting in Sludge Dewatering Buildings

When the filter-press platform and the sludge hopper or loading bay are at different elevations, the MS400 × 29.2 m completes the lift in a single 45° run, replacing multi-stage belt transfers and reducing equipment count and maintenance points.

Feed to Sludge Drying / Incineration Lines

Before a low-temperature dryer, incinerator, or co-processing unit, the conveyor lifts filter cake continuously to a high-level inlet — forming a "crushing–conveying–buffering" system with the double-tooth-roll filter cake crusher and sludge hopper.

Sand Washing and Slurry Handling

For sand-laden tail slurry, the 8 mm wear-resistant bottom plate resists abrasive wear, and enclosed conveying prevents mud splashing on site.

Sizing Notes

• Capacity basis: 8 t/h is the design capacity under 45° inclined duty (0.25 m/s chain speed); the same trough width delivers more in horizontal layout — recalculate power and chain strength for the required lift height.
• Site interfaces: inlet/discharge elevations and flange dimensions can be customized to match upstream dewatering equipment outlets and downstream hopper inlets; the unit ships in sections for field assembly.
• Material fit: suited to dewatered sludge (approximately 60%–80% moisture) and granular/powdered materials; for highly sticky material, a replaceable wear-resistant liner and regular flight inspection are recommended.
