AI Technical Summary
The decreasing availability of sea sand due to environmental changes in seaside areas around Japan has created a need for alternative materials that can be used as substitutes in construction and concrete applications.
A method of processing waste insulators and similar materials into fine powders with particle sizes of 5mm or less, using a cage mill roll mill, which can then be used as a substitute for sea sand in mortar and concrete materials.
This method allows for the creation of new materials that can be used effectively in various fields, including construction, as a strong and versatile substitute for sea sand, reducing waste and environmental impact.
Abstract
Description
[Technical field]
[0001] The present invention relates to a new material that can be used as a building material such as a powdered material, for example, ceramic roof tiles, mortar material, etc., and can replace sea sand that has been used as a material for concrete in the past. The new material is made by making coarse sand of 5mm to 2mm and mixing it with fine sand available in Japan, and mixing the coarse sand with the existing product (fine sand) to create new sand. Prior Art
[0002] This type of material had never been developed prior to the present invention, but there were base materials that existed in nature and could be used as mortar materials, such as sea sand.
[0003] However, such base materials are becoming difficult to obtain due to environmental changes in the coastal areas near Japan and the decrease in sea sand and other resources. Waste insulators and the like are prepared as the base material, and these are fed into the roll mill from above as lump-like raw materials. The cage mill and roll mill are then rotated to crush the lump-like materials into sand-like granules with a particle size of 5 mm or less. The powder state is sorted through a screen, and those with larger particles are fed back and reduced again, and the material is circulated and crushed repeatedly to crush the material into particles of 5 mm or less until the particle size is adjusted. The material is then placed in bags of the required size and piled up at a construction site, etc. for use. No method of using such materials existed.
[0004] The proposal of the present invention is related to a problem invention, and does not focus on any particular problem in the prior art, but is a proposal regarding a completely new material. Until now, the general approach has been to set out separate issues and propose solutions to them, but the present invention proposes a method that has not existed or been used before, and that creates materials from new fields rather than using primitive materials such as sea sand.
[0005] As an alternative to conventional sea sand, we discovered new materials such as used and unnecessary insulators and similar raw materials, crushed them into powder, stored them, and wondered if we could use them in place of sea sand. In short, it would be a waste to simply discard them. The present invention aims to use unnecessary insulators as a resource to obtain a material to replace sea sand.
[0006] The processing method is to put unnecessary insulators into a cage mill / roll mill, crush them in the rotating cage mill / roll mill, and repeatedly crush them until the diameter is 5mm or less.To do this, the crushed material is filtered through a screen, and larger pieces are fed back and repeatedly crushed until the target diameter is 5mm or less. This makes it possible to mimic the appearance of sea sand and use it in place of mortar materials. In this case, materials similar to the insulators that can be crushed may be mixed and used. The crushing device used is preferably a cage mill or a roll mill.
[0007] In the present invention, it is preferable to carry out the method as follows. Typically, the objects are fed into a pair of roll mills from above. During this process, the storage device is vibrated, and the objects to be crushed, such as insulators, are successively drawn into the roll mills and subjected to the crushing action, but objects that are 5mm or larger and have not been crushed are returned to the feed inlet via a screen and are subjected to the crushing action once again. With this method, objects 5mm or larger are excluded from the objects to be treated with mortar. Effects of the invention
[0008] According to the present invention, a new material has been developed by the above-mentioned method, and it is extremely useful since it can be used in various fields. And because it can be used in place of sea sand, which has traditionally been used, it can be effectively used as an alternative material. Insulators are originally hard materials, but they can be crushed and used as a strong powder, so they can be mixed with lime for use in mortar and used as a raw material for concrete. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0009] Hereinafter, an embodiment of the present invention will be described. The present invention collects and gathers unnecessary insulators at the site of overhead lines, etc., and transports the insulators to the crushing site, where they are then placed in a feed hopper. This allows the insulators to be brought to the crushing site and prepared for crushing. At this time, the roll mill starts to rotate, takes in the insulators into the roll mill, and starts to crush them. At this time, the hopper is vibrated, so that the insulators are drawn in and crushing starts.
[0010] A screen is provided below the roll, and any material larger than a specified particle size, in this case 5 mm or more in diameter, is removed so that it can be subjected to crushing again, and then circulated to be subjected to crushing again.
[0011] Once a predetermined amount of the powder that has been subjected to the above-mentioned processing has been collected, it is sent to the next process. However, they can also be used for other purposes. Ceramics and other waste materials can also be crushed and mixed in in the same way. In short, it can be used not only for mixing with cement but also as road filler (-200 mesh).
