Ultra- Super - Rotor
The Ultra-Rotor and Super-Rotor are offered in a range of sizes and configurations.
The Super-Rotor differs from the Ultra-Rotor by a solid serrated rotor which runs very close to the stator. This generates much smaller but far more intense eddies in the air stream. The rotor is also cooled to dissipate any heat generated by the more intense turbulence.
The below stated table can just give an overview of some of the possibilities. The capacities and evaporation capability are dependent on the product characteristics and the values given are indicative only. Trials in our Test Centre will confirm the expected results.
The operating principle of the mill is a rotor that is fitted with special tools. It rotates at a high peripheral speed within a solid replaceable stator. The mechanical design is conservative allowing the mill to operate safely under severe conditions and high peak loadings. The tooling on the rotor and the design of the liner of the stator accelerate the particles to very high velocities within the air eddies ensuring high energy impact between the air stream and the product. Material enters the mill at the base of the rotor and on leaving the grinding zone it enters a sifting section where the oversized particles are returned to the bottom of the grinding zone.
As the micronising effect is achieved from particle attrition the wear on the mill components is minimised.
Micronising Process
The micronising process starts with feeding the material into the lower section of the mill.
The product is then controlled crushed in the airstream.
A filter-cyclone separates product and air and the product is taken out of the filter via a rotary valve.
Simultaneous drying and grinding can be achieved by simply using heated air in place of ambient air. This allows a wide range of wet products to be dried and ground with agglomeration.
The wet product is fed into the inlet of the ULTRA-ROTOR which can be heated-up to 400°C. The wet produced will be size-reduced in the ULTRA-ROTOR, which increases the surface area of the product allowing the water to evaporate spontaneously.
A dry product will be taken out of the filter. The material itself will only be exposed to very low temperatures as the evaporating water cools down the product.
You would like to make a test milling with your product? Just contact us. We are up for it!
We need 200 kg (min.) of your product.
Plant capacity, product fineness and energy consumption can all be immediately measured and refined during the test runs. A test report will be issued after the test.
Jäckering Processing GmbH with place of business in Obersteeg nearby Cologne deals with grinding and mixing of products for non-food industries.
We are in the position to grind almost every product with our special Ultra-Rotor mill as well as other mills.
By introducing hot air into the system we are able to simultaneously dry and grind which is an excellent method of handling heat sensitive or sticky materials. Explosive or very heat sensitive materials can be processed in cryogenic systems cooled with liquid nitrogen or operating within an inert atmosphere.
Operation
First of all your product will be controlled crushed in a cutting mill. Has the product reached the right size for handling it in the fine grinding mill it will be micronised. Different sifter plants are available for security sifting and fracionating afterwards.
Beside milling with a fine grinding mill there is the opportunity to mix powder products with liquid components.
All processed products can be filled in the established packages like paper sacks, big bags and boards.
