Thompsons Plant Hire has recently expanded its business into the quarrying sector. Playing a major role in this has been tracked cone and jaw crushers which have been supplied by Sandvik Construction Mobile Crushers and Screens.
To ensure they can crush, but also shape the material, Thompson’s invested in the Sandvik Mobiles’ QH331 Hydrocone crusher to work alongside a QJ341 jaw crusher – the flagship of the Sandvik jaw crusher range, and consistently one of the world’s best-selling tracked crushers. The QJ341 has been designed to be equally productive in both hard rock and recycling applications, and is therefore the ultimate all round workhorse providing maximum efficiency and productivity whilst minimizing cost of ownership.
The QJ341 features the 1200 x 750mm C12 single toggle jaw crusher on a heavy duty mainframe, making it able to withstand arduous working conditions. It also features a reversible crushing action to relieve blockages, making it the ideal choice to tackle the most difficult applications. The QJ341 is also a very efficient choice as the jaw can operate at up to 283rpm and features hard-wearing manganese jaw plates.
On Thompson’s Whinstone application, the QJ341 is feeding the QH331 cone crusher. The QH331 is a compact, high quality machine designed to meet high product quality demands through the use of the renowned Sandvik CH430 Hydrocone crusher but on a tracked chassis. It is a very flexible machine offering a choice of six different crushing chambers and a variety of bush settings. Possessing sturdy construction, its power management, coupled with the market leading CH430 cone crusher, makes the QH331 ideal for aggregate production wherever it is needed.
A key attribute of the QH331 is that its CH430 cone possesses a deeper crushing chamber than other comparable machines. The material is therefore in the chamber longer, optimising reduction and providing a superior product shape. The CH430 is also equipped with a hydroset CSS regulation system, which allows the operator to adjust the CSS (closed side setting) whilst crushing via the main control panel.
For Thompson’s specific application the jaw on the QJ341 was set to 100mm (4”) to feed the QH331 cone, and has been producing 0-40mm type one material at an overall approximate production capacity of 130 tons per hour. This, and other factors, has meant that Kevin Thompson, owner and founder of Thompsons Plant Hire, is very pleased with his first involvement with Sandvik; “For our first crushing project we chose from the Sandvik Mobiles range as we found the machines we wanted were readily available, and were able to be supplied quickly, which was very important to our project.”
On the machines’ overall performance, the QJ341 and QH331 have proven to be a wise choice. Kevin continues: “We needed mobile crushers that would be sturdy, reliable and highly productive. These deliver on all three. The QJ341 has a good maximum feed size which, when combined with the cone, produces a very accurate product. The flexibility of the machines has been very attractive to us, especially their ability to be used on many different applications – it makes it a great investment for us. For this project they’re doing what we expected and are operating well. Our operators have found them easy to use, and user friendly, plus the machines communicate to one another, so we know the cone won’t get overloaded.”
