The Progresses of Mining Research on Ball Mill

In recent years, there are more and more research on the improvement of the ball mill at home and abroad and the analysis of the main technical factors of the improved bearing technology is as follows:

1. Factors of the spherical roller bearing:

The spherical roller bearing has many features such as high load ability, suitable for heavy load and vibration load, good adjustable spherical ability and low limit rotary rate. The ball mill will produce huge deflection under heavy workload.

2. Sealing of the bearing:

The bad working environment of the ball mill has high requirements for the sealing of the bearing. If the sealing of the bearing is not tight and foreign matters and dust go in, the particle of the bearing rolling pipe will be abraded and the bearing will become warm, as a result, the stickiness of the lubricating grease will decrease and the lubricating effect will be reduced. If water and harmful gas go into the bearing, the spare parts of the bearing may be eroded and the service life of the bearing will be decrease. For the above-mentioned reasons, the sealing of the bearing has great importance.

Large-sized rolling bearing ball mill has been in use in foreign countries since the 1980s, and in the early 1990s, this type of ball mill was first in use in the cement industry in our country. In 2000, the rolling bearing was chosen by metallurgy and mining industry. In China, our company is the first to adopt the rolling bearing in Φ3200×3600 ball mill and its operation has been excellent since July 2005. In 2006, Hongxing Machinery successfully changed the two movable bearings of the Φ5500×1800 wet-type autogenous grinding mill into rolling bearing.

At present, the hundreds of thousands of ball mills in our country adopt rolling bearing and every ball mill is able to save electricity worth billion yuan every year without influencing the ore grinding efficiency.

As the professional manufacturer of complete sets of mining machinery, such as hammer crusher, vibrating feeder, Henan Hongxing is always doing the best in products and service.
