New Trident 125 Hi-Stak combines precision screening with enhanced stockpiling capabilities 

THE production of accurately sized aggregates in the mining, quarrying, recycling, and demolition industries is essential, as is the ability to produce large stockpiles of material. Although mobile screens have their own integrated stockpiling conveyors, they are generally relatively compact and often need to be augmented by separate specialist stockpilers. To overcome this, Screencore have combined precision screening and enhanced stockpiling capabilities with the introduction of their new Trident 125 Hi-Stak.

Providing high levels of precision screening efficiency, Screencore’s Trident scalper screens are known for their toughness and adaptability. With an exceptionally large screen area and high-capacity performance, the robust screens have the capability to handle large amounts of material, making them popular in quarrying, aggregate production, surface mining, construction, and recycling.


Likewise, Screencore’s range of highly durable stockpilers has been designed to boost operational productivity. The components of the range have been developed to work on their own or alongside Screencore’s – and other manufacturers – crushers, screens, and trommels etc. To deliver flexible, mobile stockpiling, Screencore conveyors are designed to be transportable and offer features such as twin drives, check valves, and hopper feeders.

Despite the excellence of the individual product ranges, to combine the attributes of precision screening and scalping with large material stockpiles, two pieces of equipment are generally required: a screener and a stockpiler. Now, however, Screencore have combined stockpiling and scalping/screening with the introduction of the new Trident 125 Hi-Stak. Believed by Screencore to be a first of its kind, this machine combines the benefits of an advanced scalper screen with the stockpiling capabilities of an advanced stacker.

‘Being able to produce high-quality, accurately sized aggregates is essential today, whether its materials from a surface mine, quarry, or aggregate plant, or recycled construction materials from highways, demolition, or recycling operations,’ explained Screencore director Ciarán Ryan.

‘The Screencore range of scalper screens has developed a reputation for advanced screening globally, being tough, productive, environmentally friendly, and accurate. Likewise, the Screencore range of stockpilers has been developed to deliver huge stockpiles of materials, working with their own on-board power unit, or powered by a crusher, screen, or plug-in mains or genset.’

Based on customer feedback, Screencore decided to combine stockpiling and screening excellence into one machine, the result being the New Trident 125 Hi-Stak, which we believe is a game-changing development.

‘The Screencore Trident 125 Hi-Stak really is in a class of its own,’ said Mr Ryan. ‘It combines the benefits of a modern, heavy-duty primary screen with the obvious benefits of a 24m stacker. Essentially, customers get two machines in one, resulting in remarkable reductions in carbon emissions, substantial fuel savings, and the elimination of the need for double-handling fines.’

He added: ‘The Hi-Stak is set to revolutionize efficiency across various primary screening operations. Whether it’s within the confines of a quarry, sand and gravel operation, or dealing with soil and mulch, its capacity to effortlessly screen and stockpile large quantities of fines without necessitating double-handling or the creation of a wheel-loader stockpile is hugely beneficial. Moreover, and in common with all new Screencore products, it aligns perfectly with our stated objective of prioritizing carbon-reduction.’
