2 Breitenbach. The Roll Company Grinding, refining, squeezing, crushing, flaking......these are tasks putting rolls into focus as the most important tool. Highly precise crushing rolls made by Leonhard BREITENBACH GmbH are, amongst other applications, used for preparing the following products: foodstuff including luxury foods animal feed pharmaceutical products colours fertilizers ceramics and stoneware BREITENBACH crushing rolls enhance the efficiency and profitability of various production processes in several respects. On the one hand, maintenance intervals are significantly extended without affecting reliability. This means longer machine cycles without interruption, and the repair costs are cut down to the required minimum. Reduction in energy consumption during grinding is another important benefit offered by our rolls. Furthermore, we have continuously developed our products and adapted them to actual market requirements, in dose cooperation with renowned mill and plant manufacturers. This dialogue in partnership along with our experience over many years makes BREITENBACH a reliable Partner specialising in the field of roll manufacture for all crushing applications.

3 Design BREITENBACH rolls are available in any desired dimension and design to suit all types of equipment. They meet the most exacting demands regarding TIR, surface finish and geometry. Depending on the type of roll stand, the rolls may be provided with shrunkin or bolted-on Journals or with Journals designed as an integral continuous axle. On request, the Journals may also be provided with а bore, e.g. for connection to a cooling circuit. The bearing seats are ground either cylindrically or conically, depending on customers' requirements. Materials As a roll manufacturer with its own foundry, BREITENBACH is able to offer rolls manufactured by static casting or spin casting, made from various materials, i.e.: chilled cast iron (single poured) chilled cast iron (compound casting) Special self-surfacing TM (indefinite chill) cast iron highly wear resistant TCBR- Marathon cast iron Our ränge of crushing rolls includes for example: smooth rolls corrugated rolls flaking rolls refiner rolls crumbler rolls grinding and squeezing rolls The rolls are manufactured and processed to customers' specifications. Semifinished rolls with premachined Journals or just blanks are also available.

In flour, meal and oil mills, they provide significantly better results in respect of yield and product quality, at the same time enhancing economic efficiency. The TCBR marathon grades used for corrugated rolls are characterised by high hardness and high resistanceto wear combined with excellent toughness. As compared with rolls made from chilled cast iron, the TCBR-roll is subject to less and especially to more uniform wear, which means consistent high quality of the crashed product and a significantly extended lifetime for the corrugation. Machining Maximum precision is the basic principle according to which all BREITENBACH rolls are manufactured. Advanced CNC machines ensure high-precision processing throughout the complete manufacturing process. Journals and roll bodies are processed with high precision, in accordance with customer's specification. The roll surface may be: ground corrugated shot-blasted The quality of the surface finish is guaranteed by our long experience and expertise in the precise processing of rolls. The TM-grades used for smooth- and flaking rolls guarantee almost uniform hardness over the cross section of the roll. Their self-surfacing roll body excellently adapts itself to the product to be ground, which yields outstanding feeding capacity, and therefore higher product quality and more efficient grinding.

5 о BREITENBACH смен Quality BREITENBACH rolls impress users by their perfectiy smooth running which is achieved by optimised manufacturing processes and by dynamic balancing, which is carried out for all types of rolls. The precision of BREITENBACH rolls is consistently ensured by clearly specified quality Standards, to the benefit of the crushed product and the extended service life of the roller mill.
