Expanded perlite roasting self-flowing preheating device
The invention provides an expanded perlite roasting self-flowing preheating device. According to the expanded perlite roasting self-flowing preheating device, the water content of perlite raw materialore sand is generally 4%-6%, and due to the fact that the water content is too high, after high-temperature heating, rapid volatilization of water can cause explosion of perlite. Therefore, the invalid water content of the perlite should be removed before expansion, so that water (namely effective water) required by normal expansion is reserved; and perlite can be preheated in batches through a feeding device, a feeding port cannot be blocked, perlite which does not reach the overheat temperature can be secondarily heated through a returning device, it is guaranteed that the perlite preheating effect is good, the product quality can be improved, the problem that the feeding port is blocked is solved, the working efficiency can be improved, smooth production of products can be guaranteed,and good benefits are brought to factories.
本发明提供了膨胀珍珠岩焙烧自流预热装置，珍珠岩原料矿砂的含水量一般为4％‑6％，由于含水量过高，经高温加热后，水分的急速挥发会造成珍珠岩的炸裂。所以，应首先将珍珠岩的无效水含量在膨胀前去除掉，使其保留正常膨胀所需的水分(即有效水分)；利用送料装置，可以将珍珠岩分批进行预热，不会造成进料口堵塞，利用了回料装置可以将未达到越热温度的珍珠岩进行二次加热，保证珍珠岩预热效果良好，可以提高产品的质量，解决了进料口堵塞的问题可以提高工作效率，保证产品可以流畅生产，给工厂带了很好的效益。
