全新的s-Jet® 25是一款小型的紧凑型的实验机型，是对久经考验的高温蒸汽研磨 s-Jet®系列逻辑上的补充。
因为有了这个全新的开发，就可以在实验室以干法的方法制造出纳米粒径的材料。
这个系统是由一个螺旋的蒸汽研磨机和一个集成的动态气体分级轮结合而成。可以研磨出高度精细的物料，蒸汽研磨机可毫无压力地完成。在这个系统的开发过程中，最关注的是创造出一个特别适用于非常少量的和产品样本的制造的系统。
紧凑型结构的实验机型包括所有必要的组件比如：进料，研磨，产品分离，控制单元，配件和蒸汽产生器。机器的使用面积仅需3 m2，而最大的需求高度是2450 mm，所有产品可接触的配件都是由不锈钢制成。该机器出厂时是安装好的，可以直接操作。核心的连接点是压缩空气和电力，冷却水的进入和流出只需很少的安装和调试时间。进一步的要求就是人体工程学设计和清洁简便，以及在此过程中废气物的冷凝。这允许系统弹性配置。
机器中集成的空气分级轮可以无限级调整以满足精度的要求。这点保证了精准地进行研磨参数的调整和产品质量的可再现性。
使用了这款蒸汽研磨，即使再难的产品也没有问题。另外，潮湿的产品也不许要在进口处安装预干燥装置，高温蒸汽可以将研磨和干燥同时进行。
说明书
The new s-Jet® System is a consequent further development of the air-jet mill based on the Fluidized Bed Jet Mill CGS. Using steam instead of air, a considerably higher jet energy is made available whereby higher capacities and new ranges of fineness (submicron) can be achieved in the area of dry grinding.
应用文献
From the generation of adiabatic energy through to the breakthrough in nano range particles, a joint development in economical jet milling of industrial minerals and dry grinding in the sub-micron range is described by Dr. Roland Nied.

Economical Jet Milling of Inorganic Materials and Dry Grinding into the Nanometer Range
Steam is Power
A new method of grinding for jet mills that allows finenesses in the submicron range to be obtained was described in the April 2010 issue of cpp in an article headed “Economical using steam”. Such finenesses had until then been unattainable with dry grinding. This established process, known as the s-Jet® system, is meanwhile operating successfully in numerous applications.
Micronization is the miniaturization of particles by jet milling with compressed air or other gas to a range of 2-200 microns (µm). For most dry grinding processes, 2 µm is the practical limit of the technology...

[Translate to Chinese:] The interest in finer, dry products has led to the development of more efficient jet milling processes. The first part of the paper describes the thermodynamic basic principles for generation and application of steam, and compressed gases. Practical experience has shown that in the aspired fineness range stabilization during grinding provides an enormous potential for improvement. Some selected examples demonstrate that the energy requirement can be reduced by a factor of more than two by suitable choice of stabilizers.
Micronization is the miniaturization of particles by jet milling with compressed air or other gas to a range of 2-200 microns (µm). For most dry grinding processes, 2 µm is the practical limit of the technology. Nanonization is the miniaturization of particles by jet milling with superheated steam. By using superheated steam as the grinding gas, a fluidized bed jet mill with this revolutionary technology, can produce dry powders with median particle sizes in the range of 130 nanometers (nm) with 100% of the distribution finer than 400 nm. This patented new technology, known as s-Jet®, represents a quantum leap in particle size reduction by a dry grinding process and improves the jet milling process 10-fold. s-Jet® uses steam to produce superfine particles; therefore the new term – Nanonization!
