Pendulum Roller Mill - PM

Application
Roller mills are suitable for fine grinding of soft to medium hard materials, specifically light, adhesive and temperature sensitive materials. The throughput rates vary from 100 kg/h to 80 t/h depending on mill size, material and its fineness. Depending on the material, grinding and drying of material with a humidity of 35% (in case of clay) is possible.

Pendulum Roller Mill with Direct Drive PM_DD

Gearless pendulum roller mill

-patented Direct Drive system of the mill with multipole synchrone motor
-simplified mill design, eliminating e.g. gearbox, couplings and oil lubrication
-variable grinding speed for optimized process conditions


Maintenance

-drive and mill rotor with pendulums, are completely removable in one step for efficient external maintenance
-highest process utilization due to lowest downtime

Radial Classifier SDR

Tests at the NEA's pilot plant with various materials have shown that the radial classifier mounted on airswept impact and roller mills can achieve throughput increases of 30 - 160 % versus static classifiers and 10 - 50 % versus dynamic axial classifiers. Meanwhile, more than 30 retrofits were successfully done.
The NEA Radial Classifier has a compact design, simple construction and an easy access to all inner parts. Maintenance costs are reduced to a minimum.
A quick and accurate control of the fineness and product quality can be adjustetd by the variable speed rotor drive.
This is an important advantage, especially in case of frequent product changes with different quality specifications.
