s-Jet® 超高温蒸汽磨

耐驰产品总介

这款创新的蒸汽研磨机能够精磨所有的干燥的产品,任何硬度,且实际过程中无损耗。

因为这种特殊的研磨概念,产品研磨完全是自发的。蒸汽喷发装置单独产生研磨能量。无工具磨损发生!

一个集成动态的气体分级机,在特定空间里可以无限级地调整成所需的精度。这保证了精准的研磨参数的调整和产品质量的可再现线。

就算是最难的产品也显示了机器能够做到。另外,潮湿的产品也可以研磨,并且不需要在入口装任何预干燥装置就可以瞬间干燥。

s-Jet®

新型 s-Jet®  (蒸汽,超细)

新型 s-Jet®  (专利申请中)是气流磨领域里的一项新的创新技术,颗粒细度能达到亚微米范围 (如: d50 0,2 µm) .
跟其他传统的气流磨相比较,s-Jet® 使用的是蒸汽。
Sin通过蒸汽的能量带动分级轮的高速运转,使s-Jet®® 气流磨能够把颗粒分级到亚微米级别。

首先,新型s-Jet® 的经济性能非常吸引人: 与空气相比,蒸汽产生的能量更大。转速可达1,200 m/s,对颗粒的冲击力甚至可达4倍以上, 因此产量也高。

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.

说明书

NETZSCH-Feinmahltechnik GmbH offers mixing, kneading and dispersing machines for low- to high-viscosity products as well as a variety of wet-grinding units for reduction into the nanometer range, tailor-made for each application. When it comes to the processing of dry products by cutting, fine grinding or fine classification, you will find a wealth of experience and an equally varied program of fine-impact mills, classifier and jet mills as well as fine-cutting mills and high-performance fine classifiers.

Economical Jet Milling of Inorganic Materials and Dry Grinding into the Nanometer Range

应用文献

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...

应用文献

[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.

应用文献

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!
