32 March 2014 Solids and Bulk Handling
lendinning purchased a DISAB BagVac and fixed pipework system in 2010 as part of a larger investment programme
The investment programme at Linhay Hill Quarry has doubled the capacity of stone throughput and opened up valuable limestone reserves located under the 30 year-old redundant processing plant, thus securing the long term future for the 55 year-old business.
MAJOR RE-INVESTMENT IN NEW PLANT
Back in 2010, the investment programme was to replace plant that had reached the end of its engineering lifetime, and the first major item was a new £2.5m asphalt plant in March of that year. It was designed and built with fixed pipework and inlet valves on all four floors comprising a screen, hot stone bins, mixer and skip levels, so that for the first time all floor areas and surfaces could be reached with a DISAB BagVac’s 60’ flexible suction hose. Quarry Manager at Linhay Hill, Neil Gibbs, talked about the efficiencies gained. “Previously, our quarry operatives would have done all this manually using brushes and brooms, shovels and barrows. On the upper floors of any plant, sweeping all the dust and waste into a pile is one thing, moving that down to ground level for collection and removal is quite another. “In addition, because of the very fine dust

these processes create, brushing makes more dust and there’s a significantly higher risk of dust exposure to our employees, something that we were determined to eliminate through design. As a result in each of the new plants, ie. asphalt, crushing and screening, fixed pipework systems were built-in and inlet valves were provided on each floor so that the flexible suction hoses could be attached.” “With the completion of the investment in 2012 the full potential of DISAB BagVac was realised, as our plant operatives were then able to use it to power the pipework system in all the plants and suck up everything in the way of dust and waste up to 50mm in size. This has made a dramatic difference to the dust and waste removal efficiency, and as importantly, has minimised the risk of dust exposure.”
ONE TONNE OF DUST AND WASTE A WEEK REMOVED AND 100% RECYCLED
Neil continues: “In terms of how much dust and debris is removed, it’s around one IBC or ‘Dumpy’ bag a week, approximately one tonne from all three plants. All we have to do is to move the BagVac with a forklift or telehandler to wherever it’s needed alongside the plant, connect it to the pipework inlet, turn the
