The machine is used for grinding the barite, limestone, kaolin, cerames, and slags, etc, below scale 9.3 of Mohs hardness and 280-odd sorts of non-inflammable and non-explosive stuff in the trades of mining, metallurgical industrial, chemical engineering and building material for high fine powder generation and processing. The product size is adjustable in the range of 80-425 (1000 the finest) meshes. It is possible to product 30-80 mesh coarse powder through special device in the machine.

In the main frame, a 100-1500 kg powered pressure spring is fixed to the roller suspender. After the grinder is put into effect, the roller rotates around the main shaft, and rolls closely against the ring pressed by the high pressure spring and centrifugal force. And its rolling pressure ration is 1.2 times higher than that of the Raymond grinder under the same power condition and the production output is raised to substantial degree.

When a certain degree of wear of roller and ring is effected, it is recommended to adjust the length of the spring to maintain the constant pressure between the roller and the ring. As a result, the stable output and fineness are ensured.

Grinding mills are mainly used to grind and process calcite, limestone, marble, potassium feldspar and other materials. Henan Hongxing Mining Machinery grinding mill includes Raymond mill, High Pressure Suspension Mill, European Technology Trapezium grinder, Three-rings and Medium-speed Micro-powder Grinding machine and Super Pressure Trapezium Grinding equipment. Each series has various models, which can meet users’ different requirements. Below the experts from Hongxing Machinery will tell you how to maintain and prolong its service life.

First of all, during its operation, there should be specialized staff responsible for guarding the machines, and the operating staff must have the good technical level. Before the installation, it is necessary to conduct technical training for the operating staff so that they can understand the principle performance and be familiar with the operation process. In order to make it work normally, Equipment Maintenance and Safe Operating System needs to be instituted to ensure the long-term safe-running. Moreover, it is necessary to reserve some maintenance tools and grease accessories.

Next, it should be examined and repaired after using a period, and the quick-wear parts such as grinding roll, grinding ring and scraper knife should be repaired and replaced. The bolts and nuts should be checked carefully before or after the use of hammer crusher roll device. When replacing the roll after using for more than 500 hours or so, it is necessary to clean various rolling bearings and replace quick-wear parts. As to the fueling tool, manual refueling or grease gun is a good choice.

Finally, the ball mill should be operated in strict accordance with the instructions. If the equipment breaks down halfway, it can’t be modified at random but should be maintained by professionals and technicians.
