Abstract

1397403 Coating-apparatus; vibratory mix- ing WILLIAM BOULTON Ltd 25 May 1972 [3 June 1971] 18760/71 Headings B1C and B2L Particulate material is coated with a finer powder material in a treatment chamber 13 which is subjected to vibrations. As shown in Fig. 1 the chamber 13 is of semi-toroidal shape and is lined with synthetic rubber. Particles to be coated are fed in measured quantities from a hopper 15 and the coating material from a supply 16. The treatment chamber is supported on a sleeve 6 mounted on springs 4 and is vibrated by eccentric weights 11, 12 on the shaft of a motor 9. The coating material and particles to be coated are first mixed by the vibrations and the coating material is then attracted to the surface of the particulate material by electrostatic charges built up in the material and then impact-bedded into the surface of the particles. The motor can run at 1500 rpm and produce vibrations having an amplitude of # of an inch. An exit 18 for the coated material is provided. In one modification a cylindrical drum having an upwardly coned bottom surface and a spiral ramp around the inside wall is provided. In this case materials deposited on the cone rise up the ramp so that a continuous process can be provided. In a second modification the coating chamber as a whole can have a spiral form. A removable top cover with windows can be provided on all the treatment chambers. Instead of an electric motor, electromagnetic, piezo-electric pneumatic or hydraulic vibrators can be provided and air springs instead of the coil springs 4 may be provided.
