Not only skilled in Christy Turner machinery, the team can provide grinding and fluting services for almost every make and model of flaking mill, regardless of brand. As Chris Jones, managing director of Christy Turner Ltd, explains: “Part of our site here in Ipswich is dedicated to the maintenance of our customer’s rolls. We have a busy in-house roll grinding and fluting department where we receive rolls in a variety of sizes and conditions from a wide range of roller and flaking mills. “On receiving the rolls, we remove, clean and assess the condition of the bearings. What we are looking for is any pitting or corrosion often caused by poor storage conditions after the rolls are removed from the mill or for any bearing wear due to under or over greasing. A report is generated advising our customer on the condition and if replacements are recommended.  44 | November 2016 - Milling and Grain

We assess the rolls themselves, paying particular attention to any badly worn or damaged areas. We check the roll diameter and chill depth and then grind to reveal a clean, flat surface to which a new finish may be applied, fluted or matt. “We are able to grind not just our own rolls, but also other manufacturers chilled iron rolls with sizes from 250mm diameter up to 660mm, with tapers if required.” Offering a complete range of roll finishes suitable for all types of flake production from breakfast cereal to animal feed through and other non-food applications, Christy Turner can match the finish on a roll to exact specifications. On the rare occasions that rolls require more serious repairs, Christy Turner are able to refit shafts and repair bearing journals to maximise the life of a roll. Christy Turner only uses genuine parts for ultimate reliability and performance, with all replacement parts manufactured from the most suitable materials and to the correct dimensional specification. The company maintains casting patterns for every machine in its current range and all parts have full material traceability, essential for any food or feed production. Chris added: “We stock recommended spares for all of our mills in service, which includes many mills over 40 years old. By using genuine OEM parts compatibility is guaranteed. “Naturally, over time, all rolls will require replacement and we supply and fit a wide range, however, there is a great deal you can do to enhance the life of your rolls, including regular re-grinding and servicing.” Christy Turner’s dedicated team of experienced engineers support customers with site visits throughout the year to carry out
