product description
Use of the QM-3SP20 planetary ball mill:
Planetary ball mill is a necessary device for mixing, fine grinding, small sample preparation, new product development and small batch production of high-tech materials. The product is small in size, full in function, high in efficiency and low in noise. It is an ideal equipment for scientific research units, universities and enterprise laboratories to obtain research samples (four samples can be obtained in each experiment). It is equipped with a vacuum ball grinding tank, which can be ground under vacuum or inert gas protection. Widely used in geology, mineral resources, metallurgy, electronics, building materials, ceramics, chemical industry, light industry, medicine, environmental protection and other departments.Planetary ball mill is equipped with four ball mill cans on a wheel. When the wheel turns, the central axis of the ball mill tank is for planetary motion, and the ball is ground and mixed samples in high-speed motion. The product can be crushed and mixed by dry and wet methods with different particle sizes, with a minimum particle size of 0.1 micron (1.010-4mm)

Advantages of gear drive of QM-3SP20 planetary ball mill:
Good consistency of the same process conditions, the same material, four tank grinding results are consistent.
Good repeatability of the same process conditions, the same material, multiple test results are consistent.
Easy to use without the replacement of the planet wheel belt, greatly reducing the labor intensity.
Gear transmission completely solves a series of problems caused by belt slip and belt wear in belt drive.
Several main assessment indicators of the planetary ball mill:
- Speed: The speed is an important index of the planetary ball mill. In order to make the material grind fine and fast, the appropriate rotation speed should be selected.
- Maximum continuous working time: making sub-micron or nanomaterials with planetary ball mill often requires the equipment to work at full load for more than 50 hours, and strive to make the process conditions (such as speed) not change.
- Consistency: for the same material, the same process, the requirements of two cans or four cans of grinding results are completely the same, the use of gear transmission can be completely done, and with the belt transmission is very difficult.
- Repeatability: for the same material, the same process, the result of repeated ball grinding is completely consistent. It can be done with gear drive, but not with belt drive.
- Noise: in the no-load high-speed rotation state, the noise of belt rotation is 66dB, the noise of gear transmission is 68dB, but in the full load working state, the noise of both drives is the same, 75dB. This is mainly the sound of the grinding ball material hitting each other and grinding. Because only noise in load makes sense, the noise effect of belt transmission and gear transmission is the same.
- Speed ratio: The speed ratio of revolution and rotation is a technical performance index of the planetary ball mill. This parameter has a close and complex relationship with the speed size, grinding time and other factors. In order to reduce the influencing factors in the test and simplify the process conditions, our technicians in the process of developing planetary grinding (4L), and finally selected 1:1.5 (12L) as the best speed ratio (which is basically consistent with the speed ratio of imported planetary grinding). For the majority of users from the work in the experiment and exploration, save a lot of precious time.
