Six In Line at Limestone Quarry - continued
Both Warrior and Chieftain models are equally at home screening and stockpiling aggregates, blasted rock, recyclables and mined materials such as processed ores and minerals.
The 1000 Maxtrak cone crusher can accept an 'all in' feed, thereby eliminating the need for pre-screening, which would reduce the cubicity of the finished product. The feed hopper is equipped with a level probe which maintains choke feeding of the cone crusher, improving cubical shape and increasing fines production for ‘road-base’ applications.
The taper roller bearing design, with hydraulic setting, tramp release and unblocking system, ensures excellent productivity and ease of operation. Dust suppression sprays are included as standard to reduce environmental emissions. Adjustment can be made ‘on the run’ using touch button controls with direct read-out of closed side setting.
The Premiertrak 400 pre-screen jaw crusher incorporates a fully independent high amplitude, hydraulically driven pre-screen with increased drop angle on the bottom deck to facilitate maximum throughput and capacity. Improved pre-screened material flow is achieved by an enlarged discharge opening from the under chute which allows faster movement of pre-screened material to bypass the crushing chamber.
Commenting on the Powerscreen machines, Willowtree’s founder and owner James McLeod said
We looked at the available equipment on the market and closely consulted our customer’s highly experienced quarry manager at Coxhoe and we both came to the conclusion that the Powerscreen products would be best for the job in hand. Also, we at Willowtree have enjoyed an excellent relationship with Blue Machinery Scotland and this, combined with the reputation, build quality and productivity of the Powerscreen machines, made our choice easy.
