Hi Keeley. Thank you for your question.

Sand production line adopts dry type sand making process, and it can avoid many problems about water treatment and stone powder recovery. You don’t need consider the dehydration technology of final product and the costs of mechanical dehydration and natural dehydration are also reduced. Combining dust elimination and powder removal can be propitious to environmental friendly and adjusting dust wiper to change blowing rate can control the stone powder content of final products. This system is a reliable technical support because it can provide both normal sand and compacted sand. Besides, the materials whose size is smaller than 0.08mm eliminated by dust wiper account for 88.6%. It proves that it takes great effect on controlling gradation of final products.

The stone powder made by sand production line with dry type process is easy to store and transport. Once the stone powder can substitute for fly ash in concrete or it can be used in grouting and cement, stone powder made by dry process can be reused, which will help reduce production costs.
