‘NST’ High Efficiency 4L All-Directional Lab Planetary Nano Powder Ball Mill Machine (Copy)

Overview

The comminution of the material to be ground takes place primarily through the high-energy impact of grinding balls. To achieve this, the grinding jar, containing the material to be ground and grinding balls, rotates around its own axis on a main disk whilst rotating rapidly in the opposite direction. At a certain speed, the centrifugal force causes the ground sample material and grinding balls to separate from the inner wall of the grinding jar. The grinding balls then cross the jar at high speed and further grind the sample material by impact against the opposite jar wall. In addition, impact between the balls themselves on the sample material adds to the size reduction process.

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.

• Four samples with different sizes and materials in one experiment
• Programmable interval and pause times and grinding sequences
• Stepless speed regulation, reversing function
• Smaller grinding jars also possible with an adapter
• Gear-drive offers an effective solution to problems caused by belt driving
• Grinding chamber with forced air ventilation

Please note: For the Planetary Mill, you require 2 or 4 grinding jar 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 and correspondingly higher impact energy can be used. Please take note of the useful capacity, this is not identical with the jar volume!
