Product introduction

The large disc pelletizing machine is one of the scientific and technological products developed by Changsha Tianwei. The product has the characteristics of stable operation, high pelletizing quality, low energy consumption and simple maintenance. In the same industry in the country in a leading position.

The technical staff of our company has comprehensively learned from the advanced nature of similar products in Germany in the research and development, and integrated the working conditions at home and abroad, avoiding the instability and easy vibration of the cantilever shaft support structure of the traditional ball machine. After the actual production inspection of dozens of domestic and foreign projects, it has won unanimous praise and high recognition from users.



Working principle

The disc pelletizing machine is a disc-shaped pelletizing equipment that makes fine-grained powder into pellets whose particle size meets the requirements of the next process. The granulated material is rolled and rubbed under the action of gravity, centrifugal force and frictional force in the inclined and rotating disc, and forms a cue ball under the condition of adding appropriate water. The fine-grained material rolls on the wet surface of the cue ball to make the cue ball grow and have a certain strength. The pellets of different sizes automatically run along different tracks in the disc, and the finished pellets that meet the requirements are discharged from the disc.



Product advantages and innovations

* Adopt large-diameter slewing bearing, the disk body of the ball making plate is a plane support, the body is stable without vibration during the ball making process, and the ball making quality is high.

* The output of pelletizing is large, the output of qualified balls for the 6-meter pelletizing machine is maintained at 60-90 tons per hour, and the output of the 7.5-meter pelletizing machine is maintained at 120-160 tons per hour.

* Low energy consumption, the energy consumption per ton of balls is 0.7-0.8 of the traditional ball making machine, which brings considerable economic and social benefits to the energy saving and consumption reduction of enterprises.

* Maintenance is simple. During the use of the equipment, there is no need for routine maintenance work. The 7.5-meter pelletizer is the most overhauled component of about 4.3T. Compared with the traditional pelletizing machine, it is more convenient and practical, and the amount of failure and maintenance is very small.

* Using a completely enclosed internal gear transmission system, the transmission gear is isolated from external dust, so that the tooth surface is not worn by dust and pollution, reducing the failure rate, prolonging the service life of the gear, and ensuring the operation rate.

* The disc body of the ball making disc is supported by a plane, running smoothly and without vibration.

* The center distance and clearance of the large and small gears are guaranteed by machining, and the transmission precision is high. The clearance of domestic traditional ball making has to be adjusted manually. If the clearance is too large, too small, or too biased, it will affect the precision and service life of the transmission. Some balls need to be adjusted once every two months.
