Corundum scattering machine with oscillating brush system

Versatile scattering machine designed to deliver even coating of paper and flooring.

Typical applications for this IPCO precision scattering unit include:

  • Overlay papers
  • Decorative papers
  • Safety flooring

Feeding of the powder to the funnel shaped hopper is done by vacuum sucking or auger system. Inside the hopper the powder is uniformly distributed and the level is kept constant during the scattering process. The formation of cavities and decomposition of the material is avoided through the use of a special mixer (spiked roller). The scattering roller is mounted below the hopper and is designed according to the powder size.

The powder is picked up by the scattering roller and stripped at a flexible doctor blade. The doctor blade design ensures an even dosing of the material over the whole scattering width. The scattering roller is driven by a servo drive, ensuring scattering of the required quantity (g/m2) onto the product.

A specially designed scattering roller in combination with a modified oscillating brush-off device ensures an accurate and uniform distribution of the scattering material out of the scattering roll onto the substrate.

All scattering machines are available in different sizes and capacities. Scattering machines can be supplied with vertical and horizontal transfer system for easy cleaning and maintenance work.


  • Lower investment costs compared to conventional mixing equipment
  • No resin-corundum mixing equipment required
  • No pot life for resin-corundum as only corundum is needed
  • Quick change of different sorts of corundum
  • Even distribution over complete product width delivers material savings
  • Low downtime as nozzles do not plug
  • No comminuting necessary, so rougher papers can also be coated
  • Lower energy costs
  • No change of hoses for hose pumps necessary
  • Compact system design means less space
  • Standard scattering widths from 300 – 3,000 mm
