Air Classifying Mill

The Air Classifying Mill is ideal for grinding heat sensitive and extremely cohesive material efficiently. It grinds, classifies and conveys in one step. Due to the volume of air passing through, the temperature in the grinding chamber is generally lower than that in other types of fine grinding equipment. This condition offers a primary advantage in the processing of materials with low melting points.

It Separate Fine Powder Due To The Desired Final Fineness Or Other Product Characteristic.

The Best Results And Yields Are Achieved Regardless Of Whether You Are Separating Coarse Fractions (Grit) Or Classifying Fines (De-dusting). The Limitless Adjustment Of The Classifier Wheel Separates The Particle Sizes. The Optimized Classifier Wheel Design Guarantees That Very High Finesses Can Be Achieved With Only One Classifier Wheel, Even With High Throughputs.

The User Friendly Machine Housing Allows The Machine To Be Thoroughly Cleaned, Fast, When Product Or Batches Are Changed.

Air Classifying Mill

The Innovative Air Jet Mill Is Capable Of Fine Grinding All Kinds Of Dry Products With Virtually No Contamination.

Through this specialized milling concept, product grinding is Fully Automatic. Gas jets alone create the grinding energy. No tool wear occurs!

An integrated dynamic air classifier in the housing can be infinitely adjusted to the desired fineness. This guarantees exact adjustment of the grinding parameters and reproducible product quality.

Even the hardest of products poses no problem for this machine. In addition, extremely temperature sensitive products such as wax can be processed under continuous operation.

The energy efficiency of this technology. The result is a completely new grinding method.

Until now air jet milling, due to its energy consumption, was only cost efficient when applied to high value products. Now many other materials can be economically processed in our fluidized bed jet mills.

Economy is only one of the distinguishing features of our new System. Process optimization through the adaptation of grinding conditions provides energy savings of up to 30 % compared to the conventional operation of air jet mills. Products that in the past could only be economically processed in mechanical mills, can now be micronized even more economically

Fluidized Bed Jet Mill

Universal Milling System is a compact, high speed impact mill capable of coarse granulation or fine size reduction with interchangeable rotor configurations. The Universal mill is the next step in the evolution of the Hammer & Screen Mill by providing the same grind as the classic hammer mill while adding the flexibility of a pin disc, knife rotor or attrition plates. The Diverse Selection Of Grinding Tools Allows The Mill To Be Used Universally Depending On The Application And Area Of Operation. This Of Course Also Applies Later On, When Circumstances Such As Product Characteristics Or Requirements Have Changed, The Grinding Tools Can Be Changed As Well. Materials enter from the feed hopper, guided by a screw or direct gravity, ensuring a consistent flow without overloading the mill. As the material meets the rotor's rotation, it gets drawn centrally, then flung outward by centrifugal force. During its outward trajectory, the material is finely ground between the rotor and stator, thanks to their unique interplay of impact and shearing actions. After passing the stator screen, the milled product is collected. The grinding fineness varies based on the product, rotor type, stator screen, feed rate, air intake, and rotor speed

Attrition Mill

Attrition Mill is high speed cutting mill designed for the fine size reduction of plastics, polymers and fibrous materials that do not respond well to other forms of impact milling. It is designed to grind heat sensitive and soft materials without liquid nitrogen or conditioned air.

The raw material enters the grinding zone from a feeding device through the centrally located feed inlet. Size reduction takes place between the adjustable stator plate and high speed rotating grinding plate. The particle size is reduced as it passes through the tapered plates, which has a wider gap at the centre of the plates where the materials is introduced and is closest at the periphery of the plate where material exits. The finely ground product exits the grinding zone and discharges into the product container. Essentially the fineness of the product is dictated by the number of teeth on the plates, rotational speed of the rotor, as well as the gap between the plates.

Pin Mills

Pin Mills have been developed for grinding soft and medium-hard products and for surface coating of mineral fillers. With contra-rotating pin discs, the resultant tip speed is over 200 m/s, which enables the grinding of soft to medium and hard minerals to its highest fineness. Independent control of the speed and direction of rotation of the pin disc drives give a high degree of flexibility. An airflow through the mill assists the grinding, enables the control of product temperature and provides a medium for pneumatic transfer of the product.

As standard, the mill body is a robust, welded mild steel construction. Access on the Pin mill is excellent and pin replacement is an easy operation procedure. The pin mill also represents an economical and highly efficient method of coating ultra-fine fillers with stearic acid.

Features :

Fine grinding of soft and medium hard minerals
