How do you deal with the high mud content in the sand?
Now the quality of sand, especially the quality of natural sand, with the increase in the amount of mining has been worse than before, and its main performance is that the amount of mud is large, that is, sand washing machine wash out the sand, mud content is not small.The amount of mud in concrete is strictly standard, and the mud has a great influence on the performance of concrete. On the one hand, mud affects the bond between the paste and the aggregate, i.e., the strength decreases. On the one hand, the water demand of concrete is increased, and the strength of concrete is also reduced. On the other hand, to reduce the fluidity of concrete, it is also easy to cause concrete cracks.
Sand recovery machineCompared with the dewatering sieve, the sand recovery machine has more powerful and perfect functions, not only the cleaning rate is higher, but also the fine sand can be recovered. Sand recycling machine can put water in a mixture of sand silt separation, extraction and collection of fine sand, by cleaning, dehydration, grading, improve the quality and yield of sand, greatly reducing the amount of mud sand, fine sand recovery rate is as high as 85%.
Dewatering sieveThe main functions of dewatering sieve are dewatering, desliming and stripping. They are commonly used in wet sand production line and sand washing machine, and can also be used separately. Sand washing machine through the sand, in the sand, dehydration, screening, hydraulic classification, desliming, recovery of sand, to achieve a reasonable size ratio, the mud will be reduced to less than 0.7%.
