在NEA的試驗設備上使用各種物料進行的研磨試驗結果表明，在使用氣力輸料的沖擊式研磨系統(tǒng)和擺輥式研磨系統(tǒng)中，徑向分級機相對于靜態(tài)分級機，產量可提高30?160％，相對于動態(tài)軸向分級機，產量可提高10?50％。迄今已有30多個徑向分級機系統(tǒng)改造項目順利實施并效果顯著。
The NEA Radial Classifier has a compact design, simple construction and an easy access to all inner parts.

NEA徑向分級機結構緊湊、簡單，所有內部部件易于維護。 

Maintenance costs are reduced to a minimum.

節(jié)省維修保養(yǎng)成本。
A quick and accurate control of the fineness and product quality can be adjustetd by the variable speed rotor drive.

通過調整分級機轉子轉速，可以迅速精準地達到產品的所需細度和質量要求。

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

這對于需要經(jīng)常轉換生產不同規(guī)格產品的客戶尤為重要。

SDR徑向分級機

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

**代徑向分級機SDR-K配備有錐形分級輪，具有以下突出特點：

· higher throughput capacities

· 更高的產量

· wider top cut range

· 產品**粒徑可調范圍較寬

· sharp top cuts

· 產品細度分布集中

· accurate reproducibility

· 精確控制

· 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徑向分級機為一體化設計，可實現(xiàn)在d97 = 20μm到d97 = 400μm的物料細度范圍內進行細度分級。通過錐形分級輪，可以經(jīng)濟穩(wěn)定地運行并控制產品細度在上述范圍內。

第二代NEA徑向分級器SDR-Z配備有圓柱形分級輪，設計用于高質量產品生產：

· fineness d97 = 5 μm to d97 = 200 μm

· 物料細度范圍d97 =5μm至d97 =200μm

· narrow particle size distribution

· 物料粒徑分布集中大小均勻

· no spatter particles

· 避免產品中出現(xiàn)大顆粒混入

· low revolutions on classifier wheel

· 分級輪轉速低

· less product stickings

· 較少的產品粘附

· less wear

· 磨損更低

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.

現(xiàn)在采用**型徑向分級機和擺輥式研磨機配合使用，產品細度已經(jīng)可以達到氣流磨程度。
