Cutting type grinder

The cutting grinder is set by a scale, which rotates around the turntable axis while also rotating in the opposite direction around its own axis. The samples in the tank collide and rub against each other during high-speed motion, achieving the purpose of crushing, grinding, mixing, and dispersing the samples.

Continuous squeezing and friction are carried out between the rotating mortar and pestle, and the position and pressure of the pestle are adjusted according to different samples. The samples are repeatedly squeezed, rubbed, and mixed under the action of the scraper head, achieving homogenization and mixing of the samples. By setting with a scale, while revolving around the axis of the turntable, it also rotates in the opposite direction around its own axis. The samples in the tank collide and rub against each other at high speed, achieving the purpose of crushing, grinding, mixing, and dispersing the samples. When the turntable rotates, the ball mill jar rotates around the sun wheel axis in a planetary motion. Due to the design of geometry and transmission ratios,Cutting type grinderIt can move according to the appropriate trajectory. Move along the inner wall of the grinding tank until suddenly breaking away from this motion state under certain special conditions. Passing through the grinding ball, the sample and grinding ball are washed onto the opposite direction of the tank wall. The energy generated during the impact process is several times that of a regular ball mill, resulting in good grinding effect and short grinding time.

　　Cutting type grinderIt can quickly crush soft, medium hard, tough, and fibrous samples, and more efficient cutting speed can be easily solved when dealing with heat sensitive samples. The strong output of the three-phase motor and the high torque cutting force make the instrument exhibit a tough nature when encountering extremely complex samples. Stepless speed regulation can adapt to various samples, and the motor brake can quickly stop the machine. When the grinding chamber is opened, the instrument cannot operate, ensuring safety. In addition, the instrument can be equipped with a cyclone separator, which is suitable for processing fibrous or lightweight samples and improving crushing efficiency. Configuring a spiral feeder reduces operational steps and improves experimental efficiency for small-sized or granular samples.

1. The important assembly parameter of the gear transmission device is the clearance between the tooth tips of the automatic metallographic cutting, grinding, and polishing integrated machine. The regulations stipulate that the clearance between the large and small roller teeth is 7.5-8.5mm. During the production process, if the equipment runs for a long time, the large gear ring will be subjected to force and impact deformation, gradually changing from a circular shape to an elliptical shape, to avoid the impact caused by the clearance between the tooth tips, which may cause the gear teeth to overload and break. The tooth top clearance is even lower than 6mm locally, and in the actual adjustment process, the tooth top clearance should be adjusted to 8.5-10mm.

2. The insufficient tightening force of the large gear ring is also one of the important reasons for its deformation. In production operations, the fully automatic metallographic cutting machine not only increases the bolt tightening force, but also connects the large gear ring joint surface with a 10mm thick steel plate to increase the fastening surface, prevent gear ring deformation, ensure the same angular velocity of the driving and driven wheels, and prevent inertia force caused by changes in transmission ratio, which may cause fatigue and breakage.

3. The sufficient lubrication of the transmission shaft bearings is also the main reason for ensuring their smooth operation. The cutting grinder adopts traditional regular and manual oiling, which can also ensure sufficient lubrication of the bearings. However, it is easy to cause excessive or insufficient lubricating oil. It is recommended to use mechanical timing, quantitative and scientific replenishment of lubricating grease to ensure moderate lubrication of the bearings, reduce vibration, avoid bearing wear and cage rupture, and extend the service life.
