1L Vertical Small Lab Planetary Ball Mill Machine Portable Ball Grinding Mills

1 Description

1.1 Applications

Planetary ball mill is the requisite equipment for mixing, fine grinding, small sample preparing, new product development and small volume high-tech material production. The instrument has small volume, complete function, high efficiency and low noise. It is the ideal facility to acquire research samples for research institutes, universities as well as enterprise laboratories (can acquire four samples in one experiment). If mated with vacuum ball milling tanks, it can grind samples in vacuum status. The products is extensively applied to in the fields of Geology, Mining, Metallurgy, Electronics, Construction Material, Ceramics, Chemical Engineering, Light Industry Medicine, Environmental Protection etc.

1.2 Working Principle

Planetary ball mill has four ball grinding jar holders installed on one planetary disk. When the planetary disk rotates, the jar axis makes planetary movements and the balls in the jars grinds and mixes samples in high speed movement. The instrument can smash and blend various products of different materials and granularity with dry or wet methods. Minimum granularity of grinded products can be as small as 0.1 micron.

• Cooling of the grinding chamber with a built-in fan for long grinding times

2 Technical Data

2.1 Small Lab Planetary Ball Mill line

If the sample feed is larger than these then it must first undergo preliminary size reduction.

3 Frequency Conversion Control System

3.2.1 Single direction without timing

Samples need long or non-stop milling

3.2.2 Single direction with timing

Samples need to be milled in one direction for a designated amount of time before automatic shutdown

3.2.3 Bi-direction with timing

Samples need to run clockwise for 1.5 hours for example, then counter-clockwise for another 1.5 hours and so on, for 15 total hours, before the machine shuts down itself

3.2.4 Single direction with paused interval and timing

Samples need to run for 0.5 hour for example, then pause for 1 hour, then run for another 0.5 hour in the same direction and pause for another 1 hour, for 20 cycles before auto shutdown

3.2.5 Bi-direction with paused interval and timing

4Accessories

4.1 Standard Accessories of Vertical Lab Planetary Ball Mill

4.2 Remarks

Please note: for this ball mill, you require two or four grinding jars of your choice and the corresponding number of grinding balls. The grinding jar material must also 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. However, the standard package of the mill doesn't include the grinding jars or balls. They must be ordered as accessories.
