Abstract

The invention relates to the building materials industry, in particular, to installations for the production of expanded clay. The aim of the invention is to improve the quality of products, to save pollutants and to eliminate its XRD. are fed into the atomizer 3 as an oil-jet pump is used. From the atomizer 3, the mixture is fed into the rotation by the action of air entering the air intake pipe 2. Burning kiln 1 loaded with raw granules of expanded clay. During the movement of particles filled with fuel oil, fuel burns and the particles are heated to temperatures close to the temperature of the torch, which settle on the surface of the granules 1 or 2 tabs C

Claims (1)

Claim An expanded clay roasting apparatus, comprising a rotary kiln, an air supply pipe with a spray gun disposed therein connected to a liquid fuel supply source, and a hopper with an dusting apparatus. This is because, in order to improve the quality of the product, save dusting and prevent dusting, it is equipped with a mixer installed between the fuel supply source and the sprayer and connected to the dusting hopper. while the sprayer is made in the form of a fuel oil cassette.
