Size Reduction by Crushing/Kibbling

Through contract manufacture Exwold provides crushing and kibbling services.

Kibbling could be the perfect solution to providing you manageable feed source from materials that are:

  • Fused
  • Compacted
  • Hardened

What is Kibbling?

Kibbling is a particle size reduction technique often referred to as crushing, de-compaction or granulating

Crushing/kibbling uses cheese-grater type screens or rotating knives to provide a coarse product with particle diameters of between 3mm and 25mm. Exwold can process products tailored to your specification and packaging requirements.

Call us on +44 (0)1429 230346 to discuss how we can work together to make your materials work better for you.

At Exwold, we offer a number of different types of milling processes for solid particle size reduction.

  • Using our hammer/pin mills we can produce a coarse material with a particle diameter of 2000 microns or below.
  • Using our Baumeister Turbo mill we can achieve smaller particle sizes down to 75 microns.
  • We can process sensitive materials with an explosion rating up to KST2 where the mills are equipped with systems such as Kidde-Graviner Explosion Suppression systems.

We have experience of contract milling products for a wide range of speciality markets including Plastic Additives, Powder Coatings, Catalysts and Chemical Intermediates. With this experience, we can help you to achieve the precise specification you require through evaluation of the exact nature of your product, safety requirements and available milling options.
