在NEA的试验设备上使用各种物料进行的研磨试验结果表明，在使用气力输料的冲击式研磨系统和摆辊式研磨系统中，径向分级机相对于静态分级机，产量可提高30〜160％，相对于动态轴向分级机，产量可提高10〜50％。迄今已有30多个径向分级机系统改造项目顺利实施并效果显著。
The NEA Radial Classifier has a compact design, simple construction and an easy access to all inner parts.

NEA径向分级机结构紧凑、简单，所有内部部件易于维护。 

Maintenance costs are reduced to a minimum.

节省维修保养成本。
A quick and accurate control of the fineness and product quality can be adjustetd by the variable speed rotor drive.

通过调整分级机转子转速，可以迅速精准地达到产品的所需细度和质量要求。

This is an important advantage, especially in case of frequent product changes with different quality specifications.

这对于需要经常转换生产不同规格产品的客户尤为重要。

SDR径向分级机

The first generation of radial classifier SDR - K with conical classifier wheel has the following outstanding features:

**代径向分级机SDR-K配备有锥形分级轮，具有以下突出特点：

· higher throughput capacities

· 更高的产量

· wider top cut range

· 产品**粒径可调范围较宽

· sharp top cuts

· 产品细度分布集中

· accurate reproducibility

· 精确控制

· lower spec. energy consumption

· 低能耗

The NEA Radial Classifier was designed as integrated mill classifier for the classification of materials in an fineness range from d97 = 20 µm up to d97 = 400 µm. This range of fineness can be achieved economically and without any problems by using a conical classifier wheel. 

NEA径向分级机为一体化设计，可实现在d97 = 20μm到d97 = 400μm的物料细度范围内进行细度分级。通过锥形分级轮，可以经济稳定地运行并控制产品细度在上述范围内。

第二代NEA径向分级器SDR-Z配备有圆柱形分级轮，设计用于高质量产品生产：

· fineness d97 = 5 µm to d97 = 200 µm

· 物料细度范围d97 =5μm至d97 =200μm

· narrow particle size distribution

· 物料粒径分布集中大小均匀

· no spatter particles

· 避免产品中出现大颗粒混入

· low revolutions on classifier wheel

· 分级轮转速低

· less product stickings

· 较少的产品粘附

· less wear

· 磨损更低

Now it is possible for the first time to achieve with a radial classifier and an pendulum roller mill the same fineness as by using a jet mill.

现在采用**型径向分级机和摆辊式研磨机配合使用，产品细度已经可以达到气流磨程度。
