摘要： The present disclosure concerns expandable silica particles having a coating comprising talc powder and kaolin powder provided on the outer surface of the expandable silica particle and expandable and expanded silica particles comprising silica fume and/or ultrafine quartz silica sand beneath the surface of the particles. Methods for producing expandable and expanded silica particles are disclosed, including a method using a vibration plate and a furnace having a vibration plate for carrying out that method. The expanded silica particles have high compressive strength, substantially uniform cell size and distribution, low water absorption, and low porosity on the outer surface. They are useful as a filler in matrix materials, like concrete or epoxy, as insulation material with various binder materials, and as water filtration medium.

摘要： Expansion of granular or particulate material is effected by supplying such material, for instance slate chips, at a charging zone CZ of a kiln 10, to the upper surface of a rotating annular hearth 12 so as to lie thereon in a uniform layer up to about three chips in thickness. The hearth 12 is rotating in the direction of the arrow 96, and the chips face thereon just after a preheating zone PHZ. The chips are carried successively through a treatment zone TZ wherein they are subjected to heat from regenerative burner arrangements 68, 70 and 64, 66 beneath hood 44, to a discharge zone DZ whereat they are loosened by a reciprocating rake 80, 82 and are blown off the hearth 12 and into a receiver 88 by air jets from radially directed nozzles 78 supplied by way of a manifold 76.

摘要： A rotary kiln (10) is employed which is inclined downwardly from its charge end (12) to its discharge end (14) and has a maximum length to breadth ratio of 5:1. The interior space of the kiln (10) is heated by means of at least one burner (B1, B2) directed into the kiln from one end thereof to a substantially constant elevated process temperature. Material is fed into the kiln (10) so that it occupies a maximum of 10% of the cross-sectional area of the internal space of the kiln (10) at the charge end (12). Upon entering the kiln the material is subjected almost immediately to the required process temperature. As it moves along the bottom of the kiln (10) from the charge to the discharge end (14), heat transfer to the material is primarily by radiation from the combustion space and from the lining of the kiln (10).

The kiln, and its manner of use, enables expansible material, such as slate chips, to be substantially fully expanded and thereby achieve a product, suitable for use as a lightweight aggregate, of minimum possible density.

摘要： In order to manufacture large-size porous shaped bodies of low density by swelling clay masses by supplying heat thereto, a plate-like, self-supporting clay mass is used, it is given an all-round support by direct acting, multiple linear solid body contact and at the same time maintained in constant motion relative to the support, and the surface of the swelling clay mass is subjected to constant oxidation by the supply of oxidizing hot gases to the surfaces of the plate-like moving clay mass.
