There are many reasons why the sand drying effect is not good. The first reason may be the weather, such as rainy weather and high humidity, which will prolong the drying time of the sand. Secondly, it may be that the thickness of the sand layer used for drying is too large, causing the heat to not be transferred evenly, thus affecting the drying effect. In addition, if the temperature of the drying equipment is not high enough or the drying time is not long enough, the sand drying effect will also be poor.
To solve the problem of poor sand drying effect, the following measures can be taken. First of all, the drying time needs to be determined based on the thickness and humidity of the sand to ensure that the sand can be fully dried. Secondly, the temperature of the drying equipment can be increased to improve the heat transfer efficiency and speed up the drying process. In addition, the layered drying method can be used to place the sand on thinner layers for drying to ensure that the heat can be transferred evenly and improve the drying effect. In addition, it is also very important to choose suitable weather conditions for drying. Try to dry when the weather is sunny and the humidity is low, which can effectively speed up the drying of sand.
By taking the above measures, the problem of poor sand drying effect can be solved, ensuring that the sand can be fully dried and improving production efficiency. At the same time, safety issues also need to be paid attention to during the sand drying process to avoid fire accidents caused by excessive temperature. Only by controlling the drying process well can the quality and use effect of sand be guaranteed.
