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 ring are very high.
1. The particular heat treatment technology is used for the big gear ring manufactured by Xinxiang Great Wall Machinery which makes the improvement in the structure optimization and the hardness of the product. The performance of wear-resistant and anti-impacting are also enhanced greatly.
2. The high strength steel was used by us in manufacturing the big gear ring. We also take the optimization for the product against the operation characteristics of the rotary kiln to ensure the stability of the component during the long time operation and extend the service life of the component.
3. Our company has rich production capability in steel castings. For the components such as the girth gear ring, we can provide them in large production quantity with short cast period and large amount.
At the core of our service system is a professional team that delivers standard, high-efficiency, and consistently good-quality services. Presently, our service network covers Central China, East China, Southern China, Northern China, and Northwestern China, among various other regions. As our sale is still on the increase, we take steps to improve our after-sales service system. At the moment, we are expanding our service area beyond China to countries all over the world.

The large ring gear is the main component of the ball mill, it needs to drive theentire barrel for a long time. The large gear mounted on the end cover of the ball mill is also called a large ring gear. Generally, it is divided into a full ring gear, a half ring gear and a quarter ring gear.
The ring gear and pinion are the key of the edge transmission device. Their reliable operation is directly related to the stable production of the mill. In order to ensure their reliable operation, in addition to strengthening the daily maintenance and regular maintenance, the installation and alignment of the ring gear and pinion are also important.
After the ring gear is closed to the cylinder according to the installation mark, tighten the connecting bolts on the mating surface, and check whether there is a step on the side of the gear (the step is required to be as small as possible, otherwise it will affect the end runout of the ring gear). Use a feeler gauge of 0.04mm to check the matching condition. It is required that the insertion depth is not more than 50mm, and the cumulative length of the gap is not more than 1 / 4 of the tooth width.
Ball mill is a major equipment in the production of power plants, cement plants, mines, chemical industry, metallurgy and other industries, the liner is one of the components of the mill, the main role is to protect the cylinder, the cylinder from the grinding body and Material direct impact and friction, help to improve the mill grinding efficiency, increase production and reduce metal consumption. As the liner in the harsh conditions of long-term conditions, maintenance and replacement of considerable volume, not only requires human, material and financial resources, but also a direct impact on productivity.
Ball mill liner plays a major role in protecting the inner wall of the anchor windlass. Different shapes of the ball mill lining plate can improve the grinding effect of the ball mill and improve the working efficiency of the ball mill. 1, flat ball mill liner, the surface smooth, suitable for installation in the fine grinding warehouse. 2, the pressure of the type of ball mill liner, suitable for coarse grinding warehouse, for low speed ball mill. 3, ladder-type ball mill liner, ladder liner is better than the pressure liner, suitable for installation in the coarse grinding warehouse. 4, small corrugated liner crest and pitch are small, suitable for fine grinding and coal mill. 5, end cover liner installed in the grinding head cover or cylinder cover to protect the end cover from wear and tear. 6, ring groove liner in the lining of the T surface for casting a circular groove, after installation to form a circular groove, suitable for multi-warehouse grinding of the first and second positions, dry, wet grinding Machine can be. 7, grading liner, grinding mill for the ideal state should be large particles of material with a large diameter grinding body to impact and crush, that is, in the direction of the mill feed with large diameter grinding body, with the material The direction of the material to the gradual reduction of the grinding body should be sequentially reduced.
