Creeton take the new Chieftain 2200

Following the purchase of a new Premiertrak 400 XA Jaw crusher in 2017, Creeton Quarry have recently purchased a Powerscreen Chieftain 2200 mobile screen to separate the crushed material at the Jurassic Limestone Quarry in Lincolnshire. The quarry has three distinct beds: Creeton Banded, Creeton Hard White and Creeton Silverbed, which are utilised for a wide range of processing and masonry projects.

While the process can be changed depending on requirements, a typical set up is for the stone to be taken from the quarry face, with any oversized being broken up by a Rammer 3077 hydraulic hammer. The stone is then loaded into the Premiertrak 400 XA which crushes the material to 100mm before feeding it to the Chieftain triple deck screen, creating 4 sizes of product. There is an agricultural lime, a 2” clean and a type one which is being fed into a second screen, a Chieftain 2100 for a specific job. The 2100 further separates the stone into a 40mm-20mm and a 20mm-5mm, as well as producing further quantities of lime dust. The oversized is extracted via the new auxiliary conveyor, which can move from 0° to 70°. This allows the
Chieftain to recirculate the oversized into an impactor crusher and back into the Chieftain depending on customer requirements.

The Chieftain incorporates 2 triple deck screen boxes and can switch between 2 and 4 bearing arrangements. The mobile screen has an integrated, high capacity variable belt feeder and the heavy-duty, single shaft screen boxes can be adjusted in terms of stroke, angle and speed. Another key feature of the Chieftain 2200 is the hydraulic screen tensioning on the bottom deck and its exceptional processing power, making it the ideal machine for operators such as Creeton who are processing large volumes.

Steve Johnson, Quarry Manager at Creeton Quarry explains his reasons for purchasing the machine, “We purchased the machine, so we could go a bit faster and harder, and get a better, cleaner product. The aggression of the screen boxes also means it can handle the British weather” The Chieftain replaced an old Chieftain 2100 at the quarry, which is one of the reasons Steve didn’t look any further than Powerscreen when upgrading. Steve highlighted “The last machine was 12.5 years old and we sold it no problem. It still worked hard until the day it was taken away on the low loader, it’s just newer machines are superior and more advanced, so we upgraded.”

The older machine meant that, at times, the Powerscreen crusher feeding the screen had to be turned down.The 2200 however is processing considerably more tonnage per hour, meaning the operators and crusher can work at their maximum capacity, making the site as efficient as possible. As Steve says, “We want to process more through bigger machines, not more men.” The products are being used for a range of purposes from electric substations, roads, private driveways and even piling mats. Helping to make a clean product are the Major Wire screens within the Chieftain. The media has reduced blinding in wet conditions and is expected to reduced wear costs by considerably increasing the lifetime of the media.

Like many quarry men Steve just wants to get on and produce. One of the reasons he chooses Powerscreen is because he knows that Blue and Powerscreen are there to support him in reaching his objectives. Ian Taylor, Blue Machinery Salesman
