The origin of the ball mill can be traced back to the earlier grinding tools and technology, but as a specific mechanical equipment, its design and application is in modern times with the development of industrial technology and materials science and gradually mature.

The basic concept of the ball mill is derived from ancient grinding methods, such as the use of stone mortar to grind grain. During the industrial revolution, with the acceleration of industrialization, more efficient large-scale grinding equipment appeared. The ball mill was developed during this period. It uses steel balls or porcelain balls inside the drum to crush and grind materials.

The design of the planetary ball mill is inspired by the principle of the planetary gear system, that is, multiple planetary gears revolve around a central gear (sun gear) and rotate around their own axis. This design allows the media in the grinding tank (usually steel balls or other grinding media) to grind the material more finely under complex motion conditions.

Although the exact invention time and inventor may be difficult to verify, but it is certain that the planetary ball mill began to be widely used in the middle of the 20th century, and with the increasing demand for nanotechnology and advanced materials research and continuous development and improvement. With the progress of technology, planetary ball mill has become an important research tool in the field of materials science, especially in the preparation of nanomaterials.

The predecessor of Nanjing Nanda Instrument Co., Ltd. is the instrument factory of Nanjing University established in 1952. Relying on the strong scientific research strength of Nanjing University, it has registered the trademark of "striving for the first", established the enterprise tenet of "creating a national brand and striving for the first", combined with the practice of scientific research and production, aiming at the international advanced level, developed and manufactured a series of high-tech products with independent intellectual property rights, and several patented products, won many national, provincial and ministerial awards.

The ball mill produced by Nanda is also the first company in China to produce ball mills, and its technology is also the first in China. Many ball mill manufacturers established in the follow-up are inextricably linked with Nantah. Either the employees who worked in Nantah started their own companies after going out, or the core technologies are imitated by Nantah. If you disassemble the equipment shell, you can find the contents. However, the best and purest things always belong to Nantah, and the others are imitators!!!
