When selecting equipment, it is necessary to consider not only the purchase cost of the shotcrete machine, but also the quality and control of the shotcrete machine equipment, as well as the use cost of the shotcrete machine equipment. So what is the difference between the screw dry shotcrete machine and the piston mortar shotcrete machine?
The screw-type dry shotcrete machine has the advantages of simple structure, smooth spraying, good continuity and easy movement. However, its biggest drawback is the high cost of use. Take the spraying 20mm thick wall plastering mortar layer as an example. The cost of consumable parts per square meter of imported screw model spraying is 1.0 ~ 1.2 yuan / ㎡ The efficiency is as high as 2.5 ~ 3.2m² per hour, but its cost is as high as 75,000 yuan per unit.
Piston mortar shotcrete machine has the advantages of fine structure, convenient maintenance, low use cost, easy to move and so on, but the purchase cost is higher. Each imported model is about 150,000 to 350,000 yuan. In terms of use cost, the use cost of the wearing parts of the imported piston mortar shotcrete machine is 20mm thick wall coating, for example, about 0.12 ~ 0.2 yuan / ㎡. In addition, Compared with the screw type mortar shotcrete machine, the piston type mortar shotcrete machine does not block the pump and is easy to clean. The actual use effect is much better than the screw type.
