High-capacity sifting, ultra fine grinding and controlled particle size distribution

Coperion offers a variety of sifting, milling and grinding solutions.

Our centrifugal sifters are used to screen, separate and remove material of different sizes, at high rates and very efficiently.

With the Kemutec range of mills the process of particle size reduction will be quick, flexible, clean and easy for the operator. While our range for size reduction solutions is extensive, all our equipment will be customized to suit our client’s need, their material, as too, the process. Our global experts will help solve your size-reduction challenges and ensure you receive the highest level of support.

Sifting Solutions

Centrifugal sifters are used to screen, separate and remove material of different sizes, at high rates and very efficiently. The process of sifting material not only allows for size classification; separating material that isn’t of the required size, but also ensures a screening process by removing unwanted material and de-risking powder handling.

Features and Benefits

  • Size classification of material by sifting and separating out material that isn’t to the required size
  • Screens material to remove unwanted material and de-risk from contamination
  • Enables high-efficiency, high-speed performance
  • 30 second screen changes, via easily removable sifter screen for inspection and cleaning
  • Quick and easy to clean, with hygienic cantilever design
  • Operator friendly – no tools typically required for stripping down and cleaning
  • Models that can process from a few kilograms per hour, to over 90 tons
  • Gravity and inline pneumatic conveying designs
  • 7 model sizes in range

Milling and Grinding Solutions

We offer a comprehensive range of versatile, efficient and innovative milling and grinding technologies: air classifier mills, cone mills as well as universal impact mills and kibblers for use in battery manufacturing.

Our Offerings

Coperion Air Classifier Mill

PPS Air Classifier Milling Machines

PPS Air Classifier Milling Machines are ideally suited for grinding ultra-fine powders, as well as heat sensitive powders. Precise control over “particle cut point” is achieved through an internal air-classifying wheel and an independent drive. It’s typical milled particle size range down to a D50 as low as 5 to 10µ.

Kemutec’s Air Classifier Mill includes a gas intake system for either air or inert gases, while its grinding media parts are interchangeable – providing easy maintenance.

To allow for simple and quick access the Air Classifier Mill also features a hinged and interlocked top cover. Its performance is extremely efficient, making the PPS Mill a popular choice for fine powder processors.

Kemutec Universal Mill

KEK Universal Mill 

The KEK Universal Mill delivers high performance for one-pass fine grinding, making it perfect for applications that require precise particle size reduction along with a high level of fineness.

To ensure optimal process efficiency and reduce downtime, the KEK Universal Mill offers a range of interchangeable grinding media, including turbine and screen grinding components, along with pinned disc grinding media. This mill is specifically engineered to deliver exceptional performance and precise control over fine particle size, processing materials to a D50 range of 100μ to 20μ.

For minimal moisture absorption and to maintain material integrity, a closed-loop air recycle milling design is available. For heat-sensitive product, optional temperature control and full cryogenic grinding capabilities are available. This also helps grind materials that are difficult to process at ambient temperatures, by first cooling the material to a rate in which it can then be successfully ground.

Kemutec Cone Mill

KEK Cone Mill 

The KEK Cone Mill is ideal for sizing in both wet and dry granulation processes. It carefully mills and grinds material, at high speed, to produce a uniform and consistent size. The KEK Cone Mill is globally recognized as one of the most versatile size reduction milling machines, due to the wide range of materials it processes. The KEK range includes the widest available, from lab through to bulk production and are widely used in the chemical processing industry for the production of batteries.

KEK Cone Mills have the ability to take a wide range of feed material and produce an equally wide range of product, making this milling machine ideal for intermediate sizing in both wet and dry granulation. For maximum process versatility, it also includes variable speed control.

Tumbler Screener 

The Tumbler Screener is a reliable option for producing raw materials and recycling battery components. It efficiently separates, removes dust, and screens materials to ensure they conform to the necessary standards for subsequent processing or reuse.

Fields of Application

  • Raw Material Production: During the manufacturing of batteries, raw materials such as lithium, cobalt, graphite, nickel, and manganese are dedusted, fractionated, and safety-screened to ensure consistency and purity.
  • Battery Recycling: In recycling operations, crushed batteries are processed through our Tumbler Screener to separate components such as foils, outer casings, and black masses, facilitating efficient recovery and reuse of valuable materials.

Benefits and Options

Key Benefits 

  • High accuracy in particle size classification
  • Durable and dependable performance
  • Versatile use for processing raw materials and recycling
  • Engineered to manage both fragile and abrasive substances

Options

  • Dust- and gas-tight design to ensure operator safety and eliminate the risk of hazardous leaks
  • Stainless steel construction that is resistant to corrosion, customized for the materials being processed
  • ATEX certification along with grounding options, featuring a conductive gasket for enhanced safety
  • Ultrasonic technology for mesh cleaning that prevents contamination
  • A range of surface finishes, including plastic coatings, to avoid contamination
  • Quick-release mechanisms and multiple deck lifting systems for efficient maintenance and cleaning
