AB2000 double production with the Sandvik QJ341 + jaw crusher

摘要

Scottish company AB2000 Ltd visited Hillhead last year and were so impressed with the QJ341+ on display that they decided to purchase this latest addition to the Sandvik range of jaw crushers there and then. Since it was delivered they have seen a marked increase in production, almost doubling capacity over their previous model. AB2000 Ltd in Scotland specialise in the supply of both operated and self-drive machinery, including crushing and screening equipment, for the construction industry, incorporated in 1995 by Adam Bruce, who has over 50 years' experience of the operated plant hire industry, the company is now Scotland's largest privately owned hirer of operated plant and equipment. A longstanding customer of Sandvik, AB2000's relationship started with the mobile crushing and screening manufacturer almost fifteen years ago with the Extec brand. Over the years they have purchased a number of machines for their expanding fleet and now own five crushers; one QJ241, three QJ341S, and a QJ341+ . Already familiar with the Sandvik QJ341 mobile jaw crusher, Chris Brown, General Manager for AB2000 visited Hillhead in June 2016 and was interested to see the latest addition to the range, the QJ341+ on display. This new model encompasses the same characteristics as the QJ341 but is fitted with a double deck pre-screen and a number of additional benefits for improved efficiency, safety and operation. Chris describes the advantages of the pre-screen and why he was impressed with the new model. "I liked the idea of the screen and the improved production. In a recycling environment it gives us the option to produce a graded stone, a Type 1 material, which is popular with our customers. In a quarry environment we can scalp out the material and be a bit more accurate so we're not wasting as much of the raw product to put forward into the secondary process" says Chris. AB2000 have been very pleased with the increased production with the QJ341+ jaw crusher and cost per tonne is looking very good says Chris. "At Hillhead Sandvik were stating an increase in production of 30% with the QJ341+. We are actually running somewhere in the region of 300-350 tonnes per hour in comparison to the QJ341 which was doing 150-200 tonne per hour, so production's well up as far as I'm concerned and I'm more than happy with it." AB2000 are currently using the QJ341+ for a crushing contract at a limestone quarry to process 25,000 tonnes of crushed stone for a blend in the concrete plant. The -500mm raw material is fed into the QJ341+ which is then crushed down to 4" and fed into a cone crusher with a CSS set at approx. 25-28mm. The crushed limestone is then fed into a double deck screen and reduced to a clean 20-25mm product.
