Equipment / Plants

CONDUX CGS Fluidized Bed Jet Mill

The fully autogenous grinding performed by the Fluidized Bed Jet Mill is carried out via a gas stream so that no wear of grinding tools can occur. The settings of a dynamic air classifier integrated into the housing, control the desired final fineness. The grinding method of this mill enables it to break down the hardest of products as well as extremely temperature sensitive Materials, due to the lack of heat development in the jet mill during processing. Finenesses ranging from d₉₇ 1 µm to d₉₇ 70 µm can be achieved.

CONDUX CSM Classifier Mill

The Classifier Mill combines a mechanical impact grinding tool with an integrated dynamic air classifier. With the help of this air classifier, very fine grain sizes of less than 10 µm can be achieved, without the disadvantages of an external closed loop classifying system. The self-regulating, internal circulation of the coarse material in the classifier mill makes its method of operation not only stable but also energy efficient. The actual grinding process takes place between a peripheral grinding track and the beaters.

CONDUX CUM Universal Mill

The Universal Mill is a fast rotating impact mill that can be used to break down a large range of products with a Mohs hardness of up to 3 to 3.5. The mill can be "universally" equipped with a diversity of grinding tools designed to fit your application, which makes it possible to operate as a blast mill, pin disc mill (single rotating and counter rotating), beater mill as well as a ridge disc mill. The finenesses that can be achieved with the CUM range between 30 and 800 µm (d₉₉), depending on the product characteristics and grinding tools used.

CONDUX CS-Z Fine Cutting Mill

Fine-Cutting Mills can be used to pulverize impact resistant, soft, elastic products. The feed product is cut by rotating knives and stationary knives built into the machine housing. In the bottom part of the housing a sheet screen with selectable hole sizes, determines the final size of the product. The most common finenesses range from 0.2 - 1 mm (or larger).

CONDUX CFS/HD-S High-efficiency Fine Classifier

This High–efficiency Fine Classifier is designed to achieve cross cuts ranging up to d₉₇ 2 µm. Guide vanes positioned around the classifier wheel combined with fresh gas disperse the feed product and short channel it to the classifier wheel. The high number of dispersion points and the short distance to the classifier wheel reduce the possibilities for the product to re-agglomerate.
Additional improvements to the classifier wheel geometry make fines dimensions possible that were not achievable with common air classifiers in the past.

Circulation Mill System Zeta^® Type LMZ

The agitator bead mill system Zeta^® can specially be used for circulation grinding of high viscosity products with high throughput rates. The highly efficient centrifugal separation system allows the use of different types of smallest grinding media (0.1 – 3 mm). This grinding system is predestined for circulation grinding down to the nanometer range.

Disk Mill System TriNex^® Type LME and LMK

The horizontal disk mills type LME and LMK are proven, continuously working laboratory and production mills for a variety of applications, especially with low to medium-viscosity products. Different grinding disk geometries and highly efficient separation systems are available for optimal processing of your products.

Intensive Mixer Type PMD-VC

The intensive mixer type PMD-VC is a mixing and dispersion aggregate for processing flowable medium to high viscosity products. The mixing tank of the intensive mixer is heatable or coolable. The eccentrically arranged high-speed dispersing disk gradually passes the dispersing tank, while the separately driven slow speed scraper with self-adjusting blades transports the product to the dispersing zone. Thus, an optimal circulation of your product is achieved.
