How to distinguish the construction technology of dry shotcrete machine and wet shotcrete machine
1. When mixing outside the cave, the dry spray process does not add water, and the solid mixture is formed. In the wet spraying process, water must be added according to the mixing ratio to form a fluid mixture.
2. Due to the different shapes of the mixture formed by the dry shotcrete machine and the wet shotcrete machine in the wet, the transportation method is different. The transportation requirements of the dry shotcrete mixture are relatively simple. Use shuttle mine or ore bucket. The vehicle can be transported, and the wet spray material must be transported by railed concrete transport vehicle.
3. The added accelerator is different. The dry spray process uses solid accelerators. The wet spray process uses liquid accelerators, and the price gap between the two accelerators is large.
4. The spraying equipment used is different. The dry spray process uses a dry shotcrete machine, and the wet spray process uses a wet shotcrete machine. There is a large price gap between the two equipment.
5. The feeding method of spraying equipment is different, because the dry shotcrete machine uses solid mixture. Therefore, manual feeding is necessary, and because the wet shotcrete machine is a concrete tanker, the equipment can be directly connected without manual feeding.
