Across International 4x1000ml Gear-Drive 4-Liter Planetary Ball Mill

PQ-N4 series planetary ball mills may be used for mixing, homogenizing, fine grinding, mechanical alloying, cell disruption, small volume high-tech material production and even colloidal grinding. They are the ideal wet/dry milling tools for acquiring research samples with high efficiency and low noise. Vacuum jars may be used to process sample within a vacuum environment.

PQ-N4 planetary ball mills have four shredding stations arranged on the "Sun Wheel" of the planetary ball mill. When the Sun Wheel rotates, the shredding balls inside the jars are subject to superimposed rotational movements, known as Coriolis Forces. The difference in speeds between the shredding balls and jars produce an interaction between frictional and impact forces, which release high dynamic energies. Minimum granularity of the final product can be as small as 0.1 micron.

A timer controls running time from 1 to 999 minutes; it also controls jars' direction of rotation and intervals. We offer various sizes of shredding jars and shredding balls in different materials in our ball mill accessories section. Depending on your application, the material your shredding media is made from may be imperative to achieving accurate results.

shredding methods

• Single direction without timing (samples need long or non-stop milling)
• Single direction with timing (samples need to be milled in one direction for a designated amount of time before automatic shutdown)
• Bi-direction with timing (samples need to run clockwise for 1.5 hours, then counter-clockwise for another 1.5 hours and so on, for 15 total hours, before the machine shuts down itself)
• Single direction with paused interval and timing (i.e. samples need to run for 0.5 hour, then pause for 1 hour, then run for another 0.5 hour in same direction and pause for another 1 hour, for 10 cycles before auto shutdown)
• Bi-direction with paused interval and timing (samples need to run clockwise for 0.8 hour, pause for 0.5 hour, then run counter-clockwise for 0.8 hour, for 20 cycles, before auto shutdown)

DISCLAIMER

Achieving the desired particles via ball mill is a research project. The project depends on the material, shredding time, speed, and combination of shredding jar and quantity/size of milling ball. It is your responsibility to find the best milling procedure based on your material. Across International offers paid sample testing prior purchase.

Please be advised that the paid sample testing is implemented to establish a general base line for the experimental procedure. Depending on the present conditions that are applied to the unit, the results may vary if the process is repeated elsewhere.

Note:
1. Except stainless steel jars, all other jars must use stainless steel vacuum jackets when used in vacuum condition.
2. Vacuum jars or jackets must be operated with a vacuum pump which sold separately.
