What are the functions and requirements of laboratory airflow crushing?
The jet mill is an ultra-fine mill, which is the most commonly used dry grinding at present. However, what functions and requirements should the laboratory airflow pulverizer have when purchasing? Unak machinery has been engaged in jet mill for many years, and the following suggestions hope to help you:

1. Determine the basic function, that is, put forward the requirements of crushing fineness, and whether it meets the crushing requirements:

At present, all manufacturers claim that the fineness of jet mill can reach nanometer level, but the actual situation is that jet mill is superfine crushing equipment, not nanometer crushing equipment. The author thinks that below 200nm can only be called nanometer, and it is difficult to reach nanometer by physical methods, so don't be misled by bad manufacturers.

Uninak jet mill, performance parameter D97,

2~45um,

That is, the fineness can be 97%, 2um.

When the average particle size is 50%, it is about 0.5~ 1um.

This performance is also the limit of the equipment, and it is aimed at some special materials. Not all materials can meet this requirement, so jet milling can't reach nanometer level.

2. Does the equipment have the function of easy cleaning?

Laboratory equipment, mainly used for a small number of samples, is easy to clean, which is a very important function. If the same sample takes 5 minutes and it takes 5 hours to disassemble and clean, this work is unimaginable for researchers in scientific research institutes.

The airflow pulverizer designed by Kunshan Younak Machinery, whether it is the main structure or auxiliary equipment, such as cyclone dust collector, pulse dust collector, feed feeder and other related equipment in all systems, has considered the basic requirements of easy disassembly and cleaning, so that laboratory users can easily disassemble the equipment in a short time, and the equipment has no dead angle and is easy to clean.

There are two kinds of air pulverizers, please don't choose the wrong one.

There are two kinds of jet mills: "fluidized bed jet mill" and "spiral jet mill", which have different functions and are suitable for different materials.

Generally speaking, drugs or viscous materials are grinded by spiral jet mill, and new materials such as batteries are grinded by fluidized bed jet mill.

Kunshan younak machinery has designed the model 100 for the laboratory, which can combine two types of jet mills to meet the requirements of different materials in the laboratory.
