Buxton Lime & Cement choose BJD Crushers

BJD Crushers have recently supplied Tarmac Buxton Lime & Cement with two of their latest design of double roll crushers. The crushers, installed at Buxton Lime & Cement’s Hindlow and Tunstead sites, are employed in the production of high purity quicklime, which is used in industrial applications such as steelmaking and the manufacture of concrete building blocks.

Tarmac Buxton Lime & Cement are the largest producers of lime and high-quality lime products in the UK and installation of the two BJD crushers is part of a major investment by Tarmac that includes the recent commissioning of a new Maerz lime kiln at Tunstead.

The BJD double roll crushers are 75x75 hydraulic-drive models, one fitted with toothed rolls and the other with smooth rolls. The robust units are particularly suited to the reduction of friable materials such as limestone. The crushing action takes place at the nip-point between the two rolls, with the roll gap setting being fully adjustable for a variety of product sizes. At Buxton Lime & Cement, the units operate round-the-clock producing 330 tonnes a day of lime from a feed of lump 40mm limestone.

Burned lime is elevated from the kiln to the crusher house and then into a vertical in-feed arrangement, that spans the full width of the rolls, ensuring even distribution of feed to the high chrome rolls. An important feature of the BJD double roll is its automatic protection device, which protects the crusher against un-crushable material by automatically opening rolls, allowing such material to pass – the rolls then automatically re-set to the original gap setting.

Ian Andrews, Tarmac’s project manager, commented: ‘The BJD double rolls are performing to expectations.

‘In fact, everyone at BJD Crushers has performed well throughout the whole process. From the outset, they were willing to carry out a series of trials, which we at Tarmac witnessed, using a rolls test machine to determine a machine specification that satisfied our precise product requirements.’
