8L Lab Planetary Ball Mill Grinding Ultra Fine Powder High Rotate Speed

QXQM series planetary ball mill has four ball grinding tanks installed on one disc. When the turn disc rotates, the mill pots revolve on their own axis and make 360 degree rotation. And the balls in the tanks grind and mix samples in high speed movement. The product can smash and blend various products of different materials and granularity with dry or wet methods. Minimum granularity of ground samples can be as small as 0.1 micron meter. It is widely used in the fields of Geology, Mining, Metallurgy, Electronics, Construction Material, Ceramics, Chemical Engineering, Light Industry Medicine, Environmental Protection etc.

Features

• Ideal for wet or dry grinding application
• Automatic and programmable control with LED display
• multiple grinding modes to choose
• High Uniformity and excellent repeatability
• Four samples with different sizes and materials in one experiment
• Grinding chamber with a built-in fan for ventilation and long time grinding

Planetary disk turnover rolling

Motor for turnover rolling can be controlled for stop and lock. 360 degrees turnover makes grinding jars rotating in multiply directions without any dead angle.

Distinct designed gear with good stability and lower noise

Distinct gear with noise of 15-20db less than that of the same model

Elegant process and fine workmanship

500 thousand high-end mold molding, 3 million precision machine manuafacturing, exquisite and durable.

to name just a few.

Planetary ball mills are available in versions with 2 or 4 grinding stations. The freely selectable machine settings, comprehensive range of grinding jars made from top-quality materials as well as the numerous possible balls charge combinations(number and ball size) allow individual adaption of the grinding parameters to the particular size reduction task.

Guidelines for sample amount and ball charge

As a rule of thumb, the grinding balls should be approximately 3 x larger than the largest sample particle. In addition to the instrument settings and the ball size, the filling level of the jar is also of crucial importance for a successful grinding process in ball mills.

When grinding bulk materials, the jar should be filled with approx. 1/3 sample and 1/3 ball charge. The remaining third is the free jar volume that is necessary for the free movement of the balls.

If an increase or decrease in sample volume is to be expected during the grinding process, the filling levels may be changed according to the range give in the table below (in case of an expected decrease in sample volume, a further deviation is possible).

For wet grinding with grinding balls <3mm the ball charge should make up 60% of the jar volume, while the sample amount should be 30%, Then density of the grinding ball materials is used to calculate the mass of the required amount of grinding balls.

*Please note: The maximum recommended speed should be considered when using those grinding ball sizes, please refer to the operating manual for further information.

Remarks:

Please note: for this TENCAN ball mill, you require two or four grinding jars of your choice and the corresponding number of grinding balls. The grinding jar material must be harder than the material to be ground. In normal cases, grinding jars and balls of the same material are used. To shorten the grinding time, larger or heavier grinding jars and grinding balls with a higher density can be used.
