Apparatus and method for producing scaly material from mineral melt

Abstract

The invention relates to a device and method for producing scaly materials from mineral melts, comprising a furnace and a feeder, the outlet of the furnace communicates with the inlet of the feeder, and the outlet of the feeder A high-temperature-resistant alloy plate is provided below the feed port, and a through hole is provided in the center of the high-temperature-resistant alloy plate. A scale forming device is provided below the high-temperature-resistant alloy plate. The discharge port of the scale forming device is connected to the inlet of the cyclone separator. The feed port is connected, and the scale forming device includes a scale collection bin, a funnel-shaped rotating dispersing disc and a motor that drives the rotating dispersing disc to rotate, and the rotating dispersing disc is arranged inside the scale collecting bin, above the rotating dispersing disc The top surface of the scale collection bin is provided with an opening matching the position of the through hole in the center of the high-temperature-resistant alloy plate, and the inner upper end of the rotating dispersing disc is provided with a number of circular and evenly distributed air injection holes.

Description

technical field [0001] The invention relates to a production device and method for mineral scale materials, in particular to a device and method for producing scale-like materials with basalt and gabbro minerals. Background technique [0002] Mineral flocculent or scaly materials made of gabbro-basalt-like rocks have the following characteristics: high chemical resistance (98% stability when boiling in H2SO4 solution for 2h), mechanical resistance, high dispersion, easy to use And quantitative adjustment, it can produce different fineness while maintaining the shape of the scales. These properties allow the flake material to be used as a polymeric protective-decorative coating in industrial and civil construction, chemical and fire-resistant coatings, various composite materials, thermal insulation materials, shipbuilding, aircraft construction, machine building and additive industrial production use . [0003] Existing methods of producing flake-like materials using miner...

Problems solved by technology

However, this method, although the most common, has many disadvantages: high consumption of materials and resources, non-uniform thickness of the glass film obtained according to the method, rapid burning of the rotating disk due to the high temperature of the melt falling on it , so that the scales obtained according to this method are not uniform in size, the temperature of the disc is changed due to the temperature of the melt falling on the rotating disc is so hot, and the part of the melt that is not cooled in time, which is converted into so-called "steel balls", Molten mineral lumps, not scales, which creates a waste product that is difficult to separate from the formed scales

Although this method can produce finer flakes than previous production methods, the resulting glass-like film is cooled very quickly, further reducing the thickness of the film by increasing the rotation speed causes the melt to separate from the surface, and the flakes obtained at this time The area and thickness are not uniform so that scales cannot be formed and the percentage of defective products obtained is also high, in this case the obtained size is also not uniform
