LBS : High-speed conveyor belt scale for high material flow

LBS (LARGE BELT SCALE) : Belt scale for high-speed and high-flow conveyors

The LBS belt scale is a versatile, continuous weighing solution ideally designed to fit a variety of conveyor types, including high-speed and high-flow models, frequently employed in mines and cement plants.

This industrial dosing device offers real-time measurement of bulk material flow conveyed on a metal apron, suitable for demanding environments. It enables a dynamic tare function without needing to empty the upstream silo beforehand.

This belt scale automatically detects belt rotation, improving dosing efficiency using its speed detection wheel. Furthermore, it ensures accurate totalisation of cumulative weight, enabling monitoring and accurate regulation of material flows.

ADVANTAGES OF THE LBS BELT SCALE

HIGH SPEED AND HIGH FLOW

Up to 7.0 m/s and 20,000 t/h.

HIGH ACCURACY AND RELIABILITY OF MEASUREMENT

this industrial solution delivers an accuracy of +/- 0.5% thanks to its analogue sensors (or optional digital sensor).

ROBUST CONSTRUCTION

A rugged speed sensor, a stainless-steel arm and an aluminium wheel with profiled thread provide protection against dirt, humidity and ice.

SMART SOLUTION

The LBS belt scale automatically detects belt rotation, optimising dosing operations using a speed detection wheel.

STAND-ALONE SOLUTION

No need for additional wiring for conveyor feedback.

EASY SERVICING AND MAINTENANCE

Simple BFC digital controller with HMI and easy-to-use menus, maintenance menu access, requires no on-site calibration if digital sensor option selected.

FLEXIBILITY

This industrial dosing system easily adjusts to all standard S20 belt conveyors and is compatible with S18 sizes (other rail sizes available on request). It can be installed both horizontally and on an incline.

SWIFT AND EASY CALIBRATION

The belt scale can be easily aligned in record time, so you can get up and running quickly.

LBS BELT SCALE APPLICATIONS

The LBS belt scale is the ideal solution for:

CEMENT INDUSTRY

Clinker, lime, limestone, raw powder, limestone-clay mix…


MINING AND ENERGY INDUSTRY

Lignite, limestone, iron ore, fly ash, coal…

OPERATING PRINCIPLE AND DESCRIPTION OF THE LBS BELT SCALE

 

The LBS belt scale comprises three main components:

/ The weighing station, at the heart of the system, uses the parallelogram principle to transmit forces to the load cell.

/ The belt speed measurement device ensures accuracy using a friction wheel in constant contact with the belt surface.

/ The SBS belt scale is connected to the BFC digital controller, which is available in wall-mounted or panel-mounted versions. The controller serves to process and manage weighing data. For more information, see the BFC page.

This belt scale is also available in a specific version for belt conveyors (SBS) as well as a version designed for apron conveyors (SAS).
