System shutdown in mines is now a thing of the past

Nov 28, 2014

Weighing system is a traditional solution in mines industry in China for calculating the mines outputs and shipping. Such weighing system easily fails and even outputs incorrect results when itwas used in the harsh environment, such as carrying heavy wet bulk for long time, or in a bad weather environment. System suppliers have to send out their service engineers each time to the mines where are far from downtown and cities. Now the Bulkscan® laser volume flowmeter generate a reliable volume flow signal, regardless of the bulk material's properties or weather conditions.  



China Huadian Corporation is one of the national electricity system enterprise group, who is owned by Chinese government, and ranked 389 in the Fortune 500. Its sub-company Huadian Engineering has an important influence in the power industry in China. It offers system solutions for power plants and even mines. They met a lot of problems in weighing system in mines end users. They are eager to find a better solution to reduce the maintenance cost, and Bulkscan® is their first choice.  




The Bulkscan® uses time-of-flight technology for non-contact measurement of volume flow on conveyor belts.The Bulkscan® works as a simple and user-friendly sensor, shorten the development time, and decrease the maintenance cost as well. It has a robust structure and is reliable. Using the multi-echo technology, the Bulkscan® LMS511 can combine time-of-flight data with the belt speed to generate a reliable volume flow signal, regardless of the bulk material's properties or weather conditions.The integrated center-of-gravity calculator can be used to detect uneven loading of the bulk material and avoid excessive belt wear. Its tough industrial housing is well suited to rugged operating conditions. An integrated heater also ensures safe operation at low ambient temperatures. All this significantly reduces maintainance costs. Those benefits touched the customer very much, and they are satisfied with the first unite during debugging, they plan to integrate our sensors to their conveyor belt controlling system for next step as a standard solution to replace weighing system.
