Ball Mill Girth Gear repairs Cast steel Girth gear initially had a relatively small fracture which was welded Weld failed almost immediately and fracture grew .
CEMEX, a major player in the cement industry, has opted for drive technology from SEW-EURODRIVE at its cement plant in the Czech Republic. Highly resilient girth gears and pinions were used to modernize two ball mills.
Limestone has been mined in Prachovice in the Czech Republic since the Middle Ages. Today, this is where CEMEX operates an integrated cement plant. Its capacity is 900000metric tons per year .
Two cement mills ball mills perform the final production step grinding the cement clinker. Thanks to SEWEURODRIVE, exceptionally robust girth gears and pinions made from high-strength austempered ductile iron ADI now keep production running smoothly.
The production process culminates in two ball mills. Each day, the 15-meter-long machines grind up to 5000 metric tons of clinker the result is ready-to-use Portland cement. In each mill, two pinions and gear units transfer the force from two 2250-kilowatt asynchronous motors to a girth gear that is directly connected to the ball mill surface.
In spring 2017, an inspection of the drives revealed significant wear in the girth gears and pinions. This rang alarm bells, as a failure would mean a production stoppage, resulting in bottlenecks in delivery and high associated costs. CEMEX therefore opted for a rapid replacement. We provided the cement manufacturer with comprehensive support right from the design phase from selecting materials and configuration through to startup . Our many years of experience with girth gears in various countries and areas of industry was a compelling factor for CEMEX.
When manufacturing girth gears, we exclusively use high-strength austempered ductile iron ADI . ADI offers much better material properties than the cast steel previously used in Prachovice. The tensile strength is at least 1000megapascals, well above the 687 to 785megapascals of the old girth gears.
In addition to this, the new material has made it possible to design the girth gears to be much more compact and lightweight . In concrete terms, we have reduced the width from 900 millimeters to 300millimeters. We have also cut the number of teeth from 238 to 180 and increased the module to 40.
A prerequisite for the material39s excellent mechanical properties is heat treatment. It changes the microstructure and gives the material impressive strength values. As a result, the new girth gears are much more resilient and less susceptible to material fatigue.
The girth gear is the major component used in rotary kiln and ball grinding mill which is required to be operated in a long time So, the quality requirements during the actual production for the big gear.
Traditional girth gears generally consist of two to four segments. The girth gear from SEWEURODRIVE is different it has multiple parts and comprises several individual compact segments. For instance, the girth gear for Prachovice consists of twelve segments . Depending on the diameter, the individual segments of this design are only one to two meters in size.

Misaligenment girth gear cement mill process misalignment girth gear cement mill process,ball mill girth gear driving by torsion shaft and More, A case study at Shiraz Cement Plant, A case study has been conducted on the wear problem of a set of large helical gears of a ball mill used for cement, girth gear is 71 Severe wear problems.
For some years now, the foundry Ferry Capitain of 173Joinville in Northeast France, a manufacturer of girth gears for cement mills, has been offering replacement ball mill girth gears made of ductile cast iron Fig. 1.Thanks to their short delivery times and the fact that they allow repair welding, these girth gears are a reliable solution in the case of repairs or replacement of components.

Girth Gear Sag Mill Commissioning Czeu Installation of grinding mill girth gear and pinion condition based monitoring kiln and ball mill girth gear the pinion-gear et price and support online cr4 - thread ball mill girth gear and pinion alignmentug 28, 2011 can someone explain how to perform a pinion amp girth gear alignment ag mill girth gear.
Pinion gear is one of the indispensable spare parts of ball mill equipment, according to the direction of tooth shape can be divided into straight teeth and oblique teeth, there are two kinds of key type and expansion type. Different specifications of the ball mill selection of pinion teeth and modulus are not the same. Mainly according to the speed of the mill and the bearing capacity of the gear itself. Regardless of the type of ball mill, the quality of the pinion is of great importance, which directly affects the operation and service life of the equipment.
The large girth gear of the ball mill not only has a large shape, but also has a certain weight. It is formed by combining two half-toothed gears, which is mainly for the convenience of disassembly and installation. The number of teeth of the large ring gear is generally even, and.
There are many factors that determine the price of pinion gear. If the pinion gear of the same specification is made of different materials, different manufacturers and different regions, the final price will be different. Mainly is the pinion material and blank weight, followed by the specific requirements and the tedious degree of gear processing.The pinion gears of ball mill manufactured by our factory are all processed by hobbing teeth or grinding teeth, the accuarcy of teeth can up to ISO6, and the tooth surface is quenched with high frequency.
We can manufacture pinion for cement ball mill pinion pinion slag ball mill, ball mill pinion of fly ash, high fine grinding machine pinion, pinion bearing ball mill, sand ball mill pinion, wet ball mill pinion, gypsum ball mill pinion, the overflow type ball mill pinion, ceramic ball mill pinion, dressing ball mill pinion, the grid mill pinion, desulfurization ball mill pinion, the wind sweep gear grinding machine, drying coal power plant coal ball mill grinding pinion, rod mill pinion and so on.
In each mill, two pinions and gear units transfer the force from two 2250-kilowatt asynchronous motors to a girth gear that is directly connected to the ball mill surface. In spring 2017, an inspection of the drives revealed significant wear in the girth gears and pinions.
