LSD High-pressure Belt Sludge Deep Dewatering System

A vertical high-pressure belt deep dewatering system designed for secondary sludge cake moisture reduction in projects with limited floor length.

Product Overview

The LSD Series Vertical High Pressure Belt Sludge Deep Dewatering System is designed for secondary deep dewatering of sludge cake after belt press, centrifuge or screw press dewatering.

With a vertical pressing roller arrangement, the system is especially suitable for projects where the length direction is limited but sufficient height space is available.

The LSD machine adopts a vertical pressing path. The pressing rollers are arranged from bottom to top, with a lower sludge inlet and a higher sludge outlet. This layout reduces the required equipment length and is suitable for sites with limited floor length but available vertical space.

The system treats sludge cake after primary dewatering. Conditioning agent is added to modify sludge structure and improve deep dewatering performance. After efficient mixing and uniform feeding, the sludge moves upward through the vertical high-pressure belt path for moisture reduction, and the final sludge cake is discharged from the upper outlet.

The basic process flow is:

Primary Dewatered Sludge Cake → Conditioning Agent Dosing → Efficient Mixing → Uniform Feeding → Vertical High-Pressure Pressing → Final Cake Output

Faqs

LSD adopts a vertical pressing roller layout from bottom to top, while SFC-SD adopts a horizontal roller layout. LSD is more suitable for sites with limited length but available height.

It treats sludge cake after primary dewatering, usually from belt press, centrifuge, screw press or similar equipment.

Under suitable sludge and conditioning conditions, sludge cake moisture can generally be reduced to 60%–70%. The HTML also states that ≤60% is possible with proper conditioning.

Because the pressing path is arranged vertically. Sludge enters from the lower section and moves upward through the high-pressure belt path before being discharged from the upper outlet.

LSD is suitable for existing sludge rooms or compact projects where equipment length is restricted but height space can be used.

Yes. Conditioning agent is normally required to modify sludge structure and improve deep dewatering performance.

Yes. The system supports automatic control and can monitor belt deviation, low air pressure, overload and external equipment stop signals.

Please provide sludge source, current cake moisture, target cake moisture, daily sludge volume, available floor length, workshop height and final disposal method.
