Welsh Slate’s Penrhyn Quarry produces some of the finest slate and slate products in the UK with a unique reputation for durability, quality and variety.
A lesser known part of the operation is the aggregate side of the business, producing materials for construction, industrial and decorative applications.
Extraction, crushing and screening operations have recently been contracted out to Hawk Contracts utilising a Metso Lokotrack LT1213S impact crusher and a Powerscreen 2100X screen.
Traditional methods of production measurement such as stock pile surveying are time consuming, inaccurate and provide only low resolution historic data.
Trimble® Loadrite solutions can help to overcome these challenges.
Trimble® Loadrite scales installed on the Powerscreen provide real-time productivity measurement and stock input tonnages, giving contractor and client a basis for charging.
Live productivity figures can be viewed on any internet connected device, whilst more in-depth productivity reporting can be generated through Trimble® InsightHQ web-based reporting.
Equipment reports give managers daily information on plant utilisation with useful metrics such as ‘black belt’ time and percentage utilisation.
Product reports give live stockpile additions and individual product breakdown versus infeed tonnages.
Managers can tailor reports to meet their own personal requirements, for example senior managers may be interested in monthly production figures whilst supervisors could be interested in hourly production output.
Close to completion, Mansfield Sand are implementing a Trimble Loadrite C-Series conveyor scale and reporting package across 5 critical conveyors at their Two Oaks Quarry near Mansfield.
Demanding improved productivity data, the Trimble equipment was selected to provide accurate weighing and detailed reporting of productivity. Near real-time data can be easily accessed by any internet connected device through Trimble 'Snapshot' daily cumulative productivity information, whilst more detailed, periodic reports are emailed automatically, evidencing plant availability and utilisation and, total production for each product. Stock balances can now be ascertained more readily as well as overall productivity.
Further enhancements will see moisture content factored and waste product automatically calculated with the deployment of virtual scales; summing totals from relevant inputs and outputs.
