A method for measuring particle size distributions of bulk materials such as cereals, cereal milling products, cereal products and the like, which is intended to enable the measurement of particle size distributions which vary by orders of magnitude. A sample of isolated particles is optically detected in an arrangement by at least two measurement methods. Preferably, detection of the contours of the particles and laser diffraction take place at the same time.

Device for determining particle sizes

A flame spray pyrolysis process for the preparation of ultrafine titania particles coated with a smooth, homogeneous coating of one or more metal oxides is provided. The metal oxide coating is achieved by contacting the titania particles with a metal oxide precursor downstream of the titania formation zone, after the titania particles have formed. The process provides titania particles with a high rutile content and a smooth and homogeneous coating of a metal oxide.

Gas phase production of coated titania

A stream of ground particles is characterized by irradiating it with electromagnetic radiation and detecting electromagnetic radiation emitted from the irradiated particles. The detecting system includes an imaging system and a color image sensor for imaging the particles by way of the electromagnetic radiation emitted by the particles. The color image sensor has sensor image elements for spectrally selective detection of the electromagnetic radiation.
