Abstract
The invention is directed to a process and apparatus for preparing coated particles, in particular a process for preparing particles that are coated with small particles using electrospraying. The coated particles produced according to the present invention find use for instance as catalysts or as pharmaceuticals. According to the invention a host particle is contacted in a gas stream where it is allowed to contact with one or more moving tribocharging particles, thus providing a charged host particle, which is subsequently contacted with charged guest particles in an electrospraying step.
