Belt Weighing at Jansen Recycling
In the Netherlands, Jansen Recycling (of A. Jansen BV) specializes in infrastructure demolition and remediation, debris recycling and a variety of concrete production. With multiple sites and installations using belt scales, maintenance and data collection are critical to success. Jansen Recycling turned to ACB-Transportbanden and Rice Lake Weighing Systems for their system maintenance and renovation.
Jansen Recycling has two different installations in Helmond for sorting material. The first is an extractive installation to sieve soil contaminated by oil or chemicals so it can be sorted into different types. Sand extracted in this process is immediately processed in the concrete mortar plant on the same site. The second installation is an Aquamotor to clean contaminated rubble, concrete and glass before the material goes back into the recycling circuit.
Conveyor Belts and Scales
Jansen Recycling uses multiple conveyor belts at their Helmond sites, and site manager John van Hout trusts ACB-Transportbanden for maintenance of these conveyors. ACB is located in Horst aan de Maas and they sell, install and service a variety of conveyor belt components in the Netherlands.
Many of the conveyor belts are also paired with belt scales, and these systems must operate reliably in rough conditions. John van Hout wasn’t satisfied with the maintenance performed by their previous belt scale supplier and, in 2017, he asked ACB if they could perform the scale and conveyor maintenance.
Belt scale maintenance is a specialized service area so ACB approached Rice Lake Weighing Systems about performing this maintenance. ACB had worked with the experts at Rice Lake’s Heteren location (formerly Master Engineering) for 10 years already, making the partnership a clear choice.
Belt Scale Maintenance and Renovation
Rice Lake’s service department has many years of experience working with belt scales and they had no problem providing maintenance for the non-Rice Lake belt scales that were installed at Jansen Recycling. After a few maintenance visits, however, Rice Lake’s experts determined that in many cases incorrect weighing frames were being used for the conveyor belt speeds. There were also numerous mechanical issues negatively impacting the accuracy of belt scales.
After speaking with van Hout, ACB and Rice Lake worked together to create a plan for conveyor belt and scale renovation. Jansen Recycling also wanted access to data from the bandwidth scales on the network, which meant expanding the plan with new electronics and a Belt Weigher Registration software package.
Belt Weigher Registration (BWR) Software
Jansen Recycling wanted more insight into their production data at their installations including tonnage, flow, operating hours and downtime. Rice Lake integrated data loggers to each of the belt scale electronics to collect and record this information.
BWR software was installed on existing computers where a web client is also hosted. The software application runs 24/7 and checks for new data every minute, processing information to be saved in their database, including:
- Machine number and name
- Belt weigher number and name
- Material specifications
- Shift data
- Production or standstill
Jansen Recycling has now been working with the belt weighers for a few months since the renovation, and they are very satisfied.
John van Hout: ‘We now know for sure what to do in terms of input for the installations and per output flows. The belt weighers are accurate enough and the BWR software package provides really good insights into what’s happening in the installations. Our management can also see and analyze what is happening in the plan from their offices.’
