KKB Group, a leading provider of integrated services to the regeneration and infrastructure sectors across the UK, has recently expanded its fleet with the addition of four new Powerscreen Chieftain 1400 Dual Power inclined screens. Based in Rochester, Kent, KKB Group is renowned for its expertise in land remediation, demolition, civil engineering, and plant hire. Among their core offerings is contract crushing and screening, where they convert concrete, asphalt, and hardcore into certified recycled aggregates such as Type 1 and 6F2.
A long-standing partnership spanning over two decades has seen Blue Machinery supply KKB Group with a wide range of Powerscreen equipment. Over the years, the Powerscreen Chieftain has proven a reliable workhorse in KKB’s operations. The Chieftain’s 4-bearing screenbox design and rugged build quality have made it the screen of choice for many demanding applications.
KKB’s recent investment in four Chieftain 1400 Dual Power machines marks a significant step in their ongoing commitment to operational efficiency and sustainability. Each unit is equipped with dual 30kW motors—one electric, one diesel—offering flexibility to power the machines either through an onboard engine or via an external power source.
In practice, the new Chieftains are being fully powered by surplus energy from KKB’s diesel-electric impact crushers, meaning the screens operate without needing to run their own engines. This approach not only results in impressive fuel savings, but also leads to lower servicing costs, reduced emissions, and a substantial drop in engine runtime. In many cases, the onboard engines are only used for tracking the machines into place, leaving them virtually untouched for most of the machine’s operational life. This unique setup means that when the time comes to sell or replace the machines, the engines are essentially brand new.
Despite the efficiencies gained by piggybacking off crusher-generated power, the Chieftain 1400 Dual Power units retain the flexibility to run independently. With a simple flick of a switch, operators can choose to run the machines using diesel power or mains electricity, making them ideal for both integrated and stand-alone applications on various job sites.
The new machines will be deployed across the UK at blue chip customer sites, supporting contract crushing and screening projects that process road planings, asphalt, and other recycled materials. The deployment highlights KKB Group’s continued investment in modern, sustainable technology and underlines their commitment to reducing environmental impact without compromising performance.
