What do claydite do and where do they use it?
Exceptional lightness and durability, ecological cleanliness and fire resistance, high strength, moisture resistance, chemical inertness and frost resistance in combination with high thermal and sound insulation characteristics make it a universal building material used in almost all types of climate.
Here are just some examples of its use: attic and basement floors, foundations of buildings and their walls, production of expanded clay blocks and construction of roads, arrangement of homestead territory and lawns. Lovers-flower growers often paint claydite with their own hands and use it as decorative decoration of flower beds and footpaths.
How to get crushed expanded clay on an industrial scale
Externally, this material resembles a porous, air-filled pebble and is called claydite gravel. It is much less common in the form of rubble or sand. The cellular structure is not always the same, and the thermal insulation properties are directly proportional to the porosity of the substance. In addition, the quality of expanded clay in many respects depends on its fraction, specific gravity and bulk density.
The material obtained in the course of production with a diameter of at least 5 but not more than 40 mm is classified as crushed stone or pebble, less than 5 mm - as sand. The quality of the building material directly depends on what the expanded clay is made of, since only a material capable of swelling is suitable for obtaining a full-fledged product.
The process of its manufacturing includes the following stages: extraction of raw materials, delivery to the place of production and storage. Then follows the processing and receipt of semi-finished raw materials, ready for roasting. And, finally, the firing itself is carried out with swelling, and then the product is cooled in the refrigerator. After that, sorting is necessary and, if necessary, additional aggregate crushing.
Equipment for the production of expanded clay - the vastness of
technology From all of the above it becomes clear that these processes require specialized warehouse areas with access roads and industrial equipment, so there is no serious talk about producing claydite at home .Although we can agree that some types of equipment can be manufactured independently in those sizes that are suitable for home use.
For example, a claydite crusher can be made by hand with the help of recommendations, which are available on the Internet.
However, in addition to the crusher, many more tools will also be needed, and for their placement - a room of at least a small workshop. Not to mention the ways to bring raw materials and storage space. And this is not home production. By the way, crushed ceramsite is produced in the case when the natural yield of the fine fraction is insufficient. By quality, it is significantly inferior to the material of small diameter, obtained as a result of the technological process.
It is for grinding the fraction to the required condition and there is a crusher for expanded clay. In general, to implement a full-fledged technological process requires a fairly large number of units of equipment. In general, without the specification of names, the following is needed:
- line for preliminary drying of raw materials, containing stone-breaking rolls, clay-ripper and drying drum;
- line for processing raw materials with rolls of fine and coarse grinding and with a paddle mixer;
- power supply;
- calcining furnace;
- belt conveyor;
- forming machine;
- layer refrigerator.
