Pulverizers for polymers and other materials

In the pulverizers segment, MAAG offers a wide range of Reduction Engineering Scheer pulverizers for different throughput ranges and applications. Our state-of-the-art product portfolio is based on 25 years of research, development, ongoing system improvement, and in-depth know-how in the grinding of plastics and other materials. The range of pulverizers extends from units for small throughputs such as for laboratory or pilot plant operations to pulverizer systems for medium to high throughputs. Key process parameters are the pulverizer disk geometry, the grinding gap setting, the feed rate of the input material, the temperature in the grinding chamber, and the screen fineness. Our pulverizer systems are characterized by high efficiency and top performance in terms of the ratio of produced kilograms to consumed energy.

Pulverizer for laboratories

The Reduction Engineering Scheer laboratory pulverizer offers the versatility and flexibility required for laboratory and pilot plant applications. It can be operated at both ambient and cryogenic temperatures. Reduction Engineering Scheer laboratory pulverizers can be used to grind polymers ranging from synthetic resins to rubber to adhesives, as well as pharmaceuticals, and even including food grades, into top-quality powder.

Pulverizer for a wide variety of applications

The REX basic pulverizer is designed for applications that do not demand a particularly tight grain size distribution. This makes it ideal for processing a wide variety of materials, especially in polymer compounding, extrusion, mold-making, and recycling.

Compact pulverizer 85XLP

Compact pulverizers are the perfect solution for medium throughput ranges, and are ideal for in-house production. The 85XLP multi-purpose pulverizers enable fully automatic production in the medium throughput range, with maximum quality performance and low operating cost. They are also the ideal solution for in-house production. Quick cleandowns and short changeover times are further benefits.


High-performance pulverizers for high demands

We meet demands for top powder quality and extraordinarily high throughput rates with our high-performance pulverizers. That improves efficiency in terms of the ratio of produced powder to required energy. Highly demanding powder producers, in particular, benefit from the performance of the pulverizer and the compact footprint of the plant.

Cryogenic pulverizers for temperature-sensitive materials

The cryogenic Reduction Engineering Scheer pulverizer uses liquid nitrogen to cool the input material before and/or during the grinding process. The extremely low temperature prevents melting of materials with a low melting point and leads to finer grains.

Accessories for pulverizers

Special retrofit kits allow the use of disposable disk technology even in pulverizers already in service. Our patented disposable pulverizer disks eliminate the need for the costly and time-consuming external sharpening process. The disposable pulverizer disks are simply replaced by new ones. The new pulverizer disks are thinner and lighter. Their light weight also improves handling during installation and removal, and reduces modification times correspondingly.

The COLORex color mixer is a great alternative to conventional high-speed mixers. The mixing process is directly downstream of the grinding process. Both dry and liquid pigments can be used for coloring. Typical cleaning times of a conventional system are shortened by the COLORex.
